Question 1
Regular
The nurse is taking a health history of a new patient. The patient reports experiencing pain in his left lower leg and foot when walking. This pain is relieved with rest. The nurse notes that the left lower leg is slightly edematous and is hairless. When planning this patients subsequent care, the nurse should most likely address what health problem?
Correct!
Incorrect
The correct answer is: B
Rationale
Intermittent claudication is the likely health problem to address, as the patient's symptoms of leg pain while walking, relief with rest, and the noted edema and hair loss suggest reduced blood flow.
A: Coronary artery disease (CAD) Angina primarily affects the chest and may not lead to leg pain, making CAD less relevant to the patient's specific symptoms.
C: Arterial embolus An arterial embolism typically causes sudden, severe pain and may not present with relief upon rest or gradual symptoms like those described in the patient.
D: Raynaud's disease This condition affects blood flow to extremities primarily during cold exposure or stress, not manifesting as exertional leg pain and edema seen in this patient.
Correct Answer: B

Question 2
Regular
While assessing a patient the nurse notes that the patients ankle-brachial index (ABI) of the right leg is 0.40 . How should the nurse best respond to this assessment finding?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Implement interventions relevant to arterial narrowing.
An ankle-brachial index (ABI) of 0.40 indicates significant peripheral artery disease, necessitating immediate interventions aimed at improving blood flow and reducing complications related to arterial narrowing.
A: Assess the patients use of over-the-counter dietary supplements.
While dietary supplements may influence overall health, they do not directly address the urgent vascular issues indicated by a low ABI score requiring immediate clinical attention.
C: Encourage the patient to increase intake of foods high in vitamin K.
Increasing vitamin K intake pertains to coagulation rather than directly improving arterial health or addressing significant arterial narrowing indicated by the low ABI measurement.
D: Adjust the patients activity level to accommodate decreased coronary output.
The ABI specifically assesses peripheral circulation rather than coronary output, making adjustments in activity level irrelevant to the vascular concerns highlighted by the patient's low ABI result.

Question 3
Regular
The nurse is providing care for a patient who has just been diagnosed with peripheral arterial occlusive disease (PAD). What assessment finding is most consistent with this diagnosis?
Correct!
Incorrect
The correct answer is: B
Rationale
Unequal peripheral pulses between extremities. This finding indicates a discrepancy in blood flow, which is characteristic of peripheral arterial occlusive disease (PAD), as it often leads to reduced perfusion in affected limbs.
A: Numbness and tingling in the distal extremities. While these sensations can occur with PAD, they are not specific to this condition and can arise from various other causes.
C: Visible clubbing of the fingers and toes. Clubbing is typically associated with chronic respiratory or cardiovascular conditions, not peripheral arterial occlusive disease, making it an unlikely assessment finding.
D: Reddened extremities with muscle atrophy. This presentation suggests severe vascular compromise or chronic venous insufficiency rather than the typical findings associated with peripheral arterial occlusive disease.

Question 4
Regular
The nurse is admitting a 32-year-old woman to the presurgical unit. The nurse learns during the admission assessment that the patient takes oral contraceptives. Consequently, the nurses postoperative plan of care should include what intervention?
Correct!
Incorrect
The correct answer is: A
Rationale
Early ambulation and leg exercises. This intervention is essential for patients on oral contraceptives to reduce the risk of venous thromboembolism, promoting circulation and encouraging recovery after surgery.
B: Cessation of the oral contraceptives until 3 weeks postoperative could increase the risk of unintended pregnancy and may not be necessary for all surgical procedures.
C: Doppler ultrasound of peripheral circulation twice daily does not address the immediate need for mobility and exercise, which are crucial for preventing postoperative complications in patients taking oral contraceptives.
D: Dependent positioning of the patients extremities when at rest does not promote circulation effectively and may lead to further complications, contrary to the objective of enhancing recovery through active movement.

Question 5
Regular
A nurse is creating an education plan for a patient with venous insufficiency. What measure should the nurse include in the plan?
Correct!
Incorrect
The correct answer is: A
Rationale
Avoiding tight-fitting socks. This measure prevents constriction of blood flow in patients with venous insufficiency, promoting better circulation and reducing the risk of complications such as swelling and discomfort.
B: Limit activity whenever possible. Reducing mobility can exacerbate venous insufficiency symptoms, leading to increased swelling and reduced circulation, counteracting the benefits of maintaining an active lifestyle.
C: Sleep with legs in a dependent position. This position can hinder proper venous return, worsening symptoms of venous insufficiency, as it promotes pooling of blood in the lower extremities.
D: Avoid the use of pressure stockings. Pressure stockings are specifically designed to support venous function; avoiding them would detract from managing symptoms effectively and improving the patient's overall condition.

Question 6
Regular
The nurse is caring for a patient with a large venous leg ulcer. What intervention should the nurse implement to promote healing and prevent infection?
Correct!
Incorrect
The correct answer is: A
Rationale
Providing a high-calorie, high-protein diet promotes healing and supports the body's nutritional needs, which is essential for recovery from a large venous leg ulcer and preventing potential infection.
B: Apply a clean occlusive dressing once daily and whenever soiled. While dressing changes are important, nutrition plays a more crucial role in the overall healing process of the ulcer.
C: Irrigate the wound with hydrogen peroxide once daily. Hydrogen peroxide can damage healthy tissues and impede healing, making it an unsuitable option for promoting recovery in this context.
D: Apply an antibiotic ointment on the surrounding skin with each dressing change. While antibiotics may help prevent infection, they do not address the nutritional needs vital for effective healing of the ulcer.

Question 7
Regular
The nurse is caring for a patient who returned from the tropics a few weeks ago and who sought care with signs and symptoms of lymphedema. The nurses plan of care should prioritize what nursing diagnosis?
Correct!
Incorrect
The correct answer is: A
Rationale
Risk for infection related to lymphedema.
Prioritizing the risk for infection is crucial due to the compromised lymphatic system associated with lymphedema, which can lead to skin breakdown and increased susceptibility to infections, especially in patients returning from tropical regions where certain infectious agents may be prevalent.
B: Disturbed body image related to lymphedema. While body image concerns may exist, the immediate priority should focus on preventing complications like infections, which pose a greater health risk.
C: Ineffective health maintenance related to lymphedema. Although health maintenance is important, it does not address the urgent threat of infection that can arise from the physical symptoms of lymphedema.
D: Risk for deficient fluid volume related to lymphedema. This diagnosis does not accurately reflect the primary concern, as lymphedema typically involves fluid retention rather than deficiency, making infection a more pressing issue.

Question 8
Regular
An occupational health nurse is providing an educational event and has been asked by an administrative worker about the risk of varicose veins. What should the nurse suggest as a proactive preventative measure for varicose veins?
Correct!
Incorrect
The correct answer is: B
Rationale
Walking for several minutes every hour to promote circulation is a proactive preventative measure for varicose veins. Regular movement enhances blood flow in the legs, reducing the likelihood of vein issues and promoting overall vascular health, which is crucial for those in sedentary roles like administrative work.
A: Sit with crossed legs for a few minutes each hour to promote relaxation. This position can hinder blood flow and contribute to increased pressure in the veins, worsening varicose veins.
C: Elevate the legs when tired. While this can provide temporary relief, it does not address the underlying risk factors associated with prolonged sitting and poor circulation throughout the day.
D: Wear snug-fitting ankle socks to decrease edema. Although they may provide some compression, they do not encourage movement or circulation, which is essential for effective prevention of varicose veins.

Question 9
Regular
A patient comes to the walk-in clinic with complaints of pain in his foot following stepping on a roofing nail 4 days ago. The patient has a visible red streak running up his foot and ankle. What health problem should the nurse suspect?
Correct!
Incorrect
The correct answer is: D
Rationale
Lymphangitis. The visible red streak running up the foot and ankle indicates inflammation of the lymphatic vessels, commonly caused by infection from puncture wounds like those from a roofing nail.
A: Cellulitis. While cellulitis involves skin and soft tissue inflammation, the specific presentation of a streak suggests lymphatic involvement rather than just localized skin infection.
B: Local inflammation. This option lacks specificity; local inflammation could refer to various conditions, but the streak's presence points towards a more systemic issue involving lymphatic vessels.
C: Elephantiasis. This condition is characterized by severe swelling and thickening of the skin due to lymphatic obstruction, not a recent infection following a puncture wound, making it irrelevant here.

Question 10
Regular
The triage nurse in the ED is assessing a patient who has presented with complaint of pain and swelling in her right lower leg. The patients pain became much worse last night and appeared along with fever, chills, and sweating. The patient states, I hit my leg on the car door 4 or 5 days ago and it has been sore ever since. The patient has a history of chronic venous insufficiency. What intervention should the nurse anticipate for this patient?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Antibiotics to treat cellulitis. The patient's symptoms, including pain, swelling, fever, chills, and the recent history of leg trauma, strongly suggest the presence of cellulitis, necessitating antibiotic treatment to combat the infection.
A: Platelet transfusion to treat thrombocytopenia. The scenario does not indicate low platelet levels or bleeding issues; thus, platelet transfusion is unnecessary and unrelated to the patient's condition.
B: Warfarin to treat arterial insufficiency. The presentation indicates an issue with infection rather than arterial insufficiency, making anticoagulation with Warfarin inappropriate for this situation.
D: Heparin IV to treat VTE. While VTE is a concern, the acute signs of infection and swelling point towards cellulitis rather than venous thromboembolism, rendering heparin unsuitable.

Question 11
Regular
A nurse in a long-term care facility is caring for an 83-year-old woman who has a history of HF and peripheral arterial disease (PAD). At present the patient is unable to stand or ambulate. The nurse should implement measures to prevent what complication?
Correct!
Incorrect
The correct answer is: B
Rationale
Deep vein thrombosis. Given the patient’s inability to stand or ambulate, she is at heightened risk for venous stasis, which significantly increases the likelihood of developing deep vein thrombosis (DVT).
A: Aoritis. This condition primarily relates to inflammation of the aorta and is not a direct consequence of immobility or the patient’s current health status.
C: Thoracic aortic aneurysm. This involves an abnormal bulge in the aorta and is unrelated to the patient's immobility or the immediate concerns associated with long-term care.
D: Raynaud's disease. This vascular condition affects blood flow to extremities due to cold or stress, not a complication stemming from immobility or the patient's existing conditions.

Question 12
Regular
A nurse is admitting a 45-year-old man to the medical unit who has a history of PAD. While providing his health history, the patient reveals that he smokes about two packs of cigarettes a day, has a history of alcohol abuse, and does not exercise. What would be the priority health education for this patient?
Correct!
Incorrect
The correct answer is: C
Rationale
Cigarettes contain nicotine, which is a powerful vasoconstrictor and may cause or aggravate PAD. Educating the patient about the detrimental effects of smoking on vascular health is crucial, as it directly impacts his condition and overall well-being, potentially worsening his peripheral artery disease through increased blood vessel constriction and reduced blood flow.
A: The lack of exercise, which is the main cause of PAD. While lack of exercise contributes to PAD, smoking and its effects on circulation are more immediate concerns needing urgent attention.
B: The likelihood that heavy alcohol intake is a significant risk factor for PAD. Alcohol can influence health, but the immediate impact of smoking on vascular constriction poses a greater risk to this patient.
D: Alcohol suppresses the immune system, creates high glucose levels, and may cause PAD. Although alcohol affects health negatively, its connection to PAD is not as direct as the impact of smoking on blood vessels.

A nurse has written a plan of care for a man diagnosed with peripheral arterial insufficiency. One of the nursing diagnoses in the care plan is altered peripheral tissue perfusion related to compromised circulation. What is the most appropriate intervention for this diagnosis?
Correct!
Incorrect
The correct answer is: B
Rationale
Encouraging the patient to engage in a moderate amount of exercise is the most appropriate intervention. Exercise enhances blood flow, improves circulation, and promotes optimal tissue perfusion, which is crucial for patients with peripheral arterial insufficiency.
A: Elevate his legs and arms above his heart when resting. This position can hinder blood flow to the extremities, potentially worsening the compromised circulation experienced in peripheral arterial insufficiency.
C: Encourage extended periods of sitting or standing. Prolonged sitting or standing can exacerbate poor circulation, negatively affecting tissue perfusion and ultimately leading to further complications for the patient.
D: Discourage walking in order to limit pain. Avoiding walking restricts blood flow and circulation, counteracting the benefits of movement that are essential for managing peripheral arterial insufficiency effectively.

The nurse is caring for a 72-year-old patient who is in cardiac rehabilitation following heart surgery. The patient has been walking on a regular basis for about a week and walks for 15 minutes 3 times a day. The patient states that he is having a cramp-like pain in the legs every time he walks and that the pain gets better when I rest. The patients care plan should address what problem?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Acute pain related to intermittent claudication. The patient’s cramp-like leg pain during walking, which improves with rest, is characteristic of intermittent claudication, indicating inadequate blood flow during increased activity.
A: Decreased mobility related to VTE. While mobility may be a concern post-surgery, the specific symptoms described do not align with venous thromboembolism, which typically presents differently.
C: Decreased mobility related to venous insufficiency. Venous insufficiency symptoms generally include swelling and discomfort rather than the cramp-like pain experienced during walking, which is more indicative of claudication.
D: Acute pain related to vasculitis. Vasculitis typically causes systemic symptoms and does not specifically relate to the intermittent leg pain experienced during exertion, making this option unsuitable.

Question 15
Regular
A nurse in the rehabilitation unit is caring for an older adult patient who is in cardiac rehabilitation following an MI. The nurses plan of care calls for the patient to walk for 10 minutes 3 times a day. The patient questions the relationship between walking and heart function. How should the nurse best reply?
Correct!
Incorrect
The correct answer is: D
Rationale
When you walk, the muscles in your legs contract and pump the blood in your veins back toward your heart, which allows more blood to return to your heart. This process enhances circulation, improving heart function and efficiency, particularly important for a patient recovering from a myocardial infarction (MI). Engaging in physical activity like walking is vital for rehabilitation.
A: The arteries in your legs constrict when you walk and allow the blood to move faster and with more pressure on the tissue. Constriction of leg arteries does not accurately describe the beneficial effects of walking on overall cardiac rehabilitation.
B: Walking increases your heart rate and blood pressure. Therefore your heart is under less stress. Increased heart rate and blood pressure during exercise actually indicate more stress, not less, on the heart during rehabilitation.
C: Walking helps your heart adjust to your new arteries and helps build your self-esteem. While beneficial for self-esteem, the primary advantage of walking relates to enhancing blood circulation and heart efficiency post-MI.

Question 16
Regular
The nurse is caring for a patient who is admitted to the medical unit for the treatment of a venous ulcer in the area of her lateral malleolus that has been unresponsive to treatment. What is the nurse most likely to find during an assessment of this patients wound?
Correct!
Incorrect
The correct answer is: B
Rationale
Heavy exudate. Venous ulcers typically present with significant fluid drainage due to poor venous return, leading to excessive exudate. This characteristic aligns with the clinical presentation of unresponsive venous ulcers, indicating underlying issues with circulation and fluid management.
A: Hemorrhage. While hemorrhage can occur in some wounds, it is not a typical finding in chronic venous ulcers, which usually exhibit other specific characteristics like exudate.
C: Deep wound bed. Venous ulcers generally have shallow wound beds rather than deep ones, as they are often superficial lesions resulting from prolonged venous pressure rather than extensive tissue destruction.
D: Pale-colored wound bed. A wound bed that appears pale suggests arterial insufficiency rather than the typical presentation of venous ulcers, which are more likely to exhibit a red or granulating appearance due to venous congestion.

The nurse is preparing to administer warfarin (Coumadin) to a client with deep vein thrombophlebitis (DVT). Which laboratory value would most clearly indicate that the patients warfarin is at therapeutic levels?
Correct!
Incorrect
The correct answer is: C
Rationale
C: International normalized ratio (INR) between 2 and 3. This range indicates that the warfarin is effectively anticoagulating the client, helping to prevent clot formation in cases of DVT.
A: Partial thromboplastin time (PTT) within normal reference range. This test primarily assesses the intrinsic pathway of coagulation and is not used to monitor warfarin therapy.
B: Prothrombin time (PT) eight to ten times the control. An excessively high PT may indicate over-anticoagulation, which can lead to bleeding complications, rather than a therapeutic level.
D: Hematocrit of 32%. Hematocrit measures red blood cell concentration and does not reflect the anticoagulation status or effectiveness of warfarin therapy in managing DVT.

The nurse should provide what instruction about long-term care to the client?
Correct!
Incorrect
The correct answer is: A
Rationale
A: Be sure to practice meticulous foot care. Proper foot care is crucial for individuals with diabetes, especially those experiencing intermittent claudication, as it prevents complications from reduced blood flow and potential ulcers.
B: Consider cutting down on your smoking. While reducing smoking is beneficial for overall health, it does not address the immediate need for careful foot care in diabetic patients.
C: Reduce your activity level to accommodate your limitations. Limiting activity can lead to further deterioration of vascular health, contradicting the importance of maintaining mobility in managing intermittent claudication.
D: Try to make sure you eat enough protein. Although protein is important for overall nutrition, it does not specifically relate to the management of foot care in diabetic patients with intermittent claudication.

A patient who has undergone a femoral to popliteal bypass graft surgery returns to the surgical unit. Which assessments should the nurse perform during the first postoperative day?
Correct!
Incorrect
The correct answer is: A
Rationale
Assess pulse of affected extremity every 15 minutes at first. Monitoring the pulse of the affected extremity at frequent intervals is crucial in the early postoperative period to identify any potential complications such as graft failure or inadequate blood flow, ensuring timely intervention if necessary.
B: Palpate the affected leg for pain during every assessment. While assessing pain is important, it does not specifically address the immediate vascular status or potential complications following bypass surgery.
C: Assess the patient for signs and symptoms of compartment syndrome every 2 hours. Although monitoring for compartment syndrome is vital, assessing every two hours may delay the timely detection of critical changes in blood flow.
D: Perform Doppler evaluation once daily. Conducting a Doppler evaluation only once daily fails to provide sufficient frequent monitoring needed in the immediate postoperative phase to ensure graft patency and limb viability.
Correct Answer: A

Question 20
Regular
You are caring for a patient who is diagnosed with Raynauds phenomenon. The nurse should plan interventions to address what nursing diagnosis?
Correct!
Incorrect
The correct answer is: B
Rationale
Ineffective tissue perfusion.
This diagnosis is appropriate as Raynaud's phenomenon leads to intermittent vasospasm, resulting in reduced blood flow to extremities. Interventions should focus on improving circulation and preventing complications associated with inadequate perfusion.
A: Chronic pain. The primary concern in Raynaud's phenomenon is not persistent pain but the effects of reduced blood flow, which may lead to discomfort rather than chronic pain management.
C: Impaired skin integrity. While skin integrity can be affected, the primary nursing diagnosis centers on perfusion issues rather than direct skin damage, making this option less relevant.
D: Risk for injury. Although there may be a risk for injury due to cold exposure, the immediate nursing diagnosis should focus on enhancing tissue perfusion rather than injury prevention.
Correct Answer: B
Rationale: Ineffective tissue perfusion.
This diagnosis is appropriate as Raynaud's phenomenon leads to intermittent vasospasm, resulting in reduced blood flow to extremities. Interventions should focus on improving circulation and preventing complications associated with inadequate perfusion.
A: Chronic pain. The primary concern in Raynaud's phenomenon is not persistent pain but the effects of reduced blood flow, which may lead to discomfort rather than chronic pain management.
C: Impaired skin integrity. While skin integrity can be affected, the primary nursing diagnosis centers on perfusion issues rather than direct skin damage, making this option less relevant.
D: Risk for injury. Although there may be a risk for injury due to cold exposure, the immediate nursing diagnosis should focus on enhancing tissue perfusion rather than injury prevention.
Question 21
Regular
A patient presents to the clinic complaining of the inability to grasp objects with her right hand. The patients right arm is cool and has a difference in blood pressure of more than 20 mm Hg compared with her left arm. The nurse should expect that the primary care provider may diagnose the woman with what health problem?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Upper extremity arterial occlusive disease. The symptoms of coolness in the right arm, inability to grasp objects, and significant blood pressure differences suggest a lack of adequate blood flow, indicative of arterial occlusion.
A: Lymphedema. This condition typically presents with swelling due to lymph fluid accumulation, not with coolness or significant blood pressure discrepancies, making it an unlikely diagnosis here.
B: Raynaud's phenomenon. Characterized by episodic vasospasm leading to color changes in fingers, it does not typically cause such pronounced blood pressure differences or significant functional impairment in grasp.
D: Upper extremity VTE. Venous thromboembolism usually presents with swelling and pain rather than coolness and functional limitations in grasp, which are more associated with arterial issues.

Question 22
Regular
A nurse working in a long-term care facility is performing the admission assessment of a newly admitted, 85-year-old resident. During inspection of the residents feet, the nurse notes that she appears to have early evidence of gangrene on one of her great toes. The nurse knows that gangrene in the elderly is often the first sign of what?
Correct!
Incorrect
The correct answer is: D
Rationale
Gangrene in the elderly is often the first sign of peripheral artery disease (PAD). This condition results from reduced blood flow due to narrowed arteries, leading to tissue damage and gangrene, particularly in the feet.
A: Chronic venous insufficiency. This condition primarily affects blood return from the legs, causing swelling and varicosities, rather than the arterial issues that lead to gangrene.
B: Raynaud's phenomenon. This disorder involves spasms of blood vessels in response to cold or stress, affecting blood flow temporarily, but it does not directly cause gangrene.
C: VTE. Venous thromboembolism refers to blood clots in veins, which may cause swelling or pain, but it does not typically result in the tissue death indicated by gangrene.

Question 24
Regular
The nurse is caring for an acutely ill patient who is on anticoagulant therapy. The patient has a comorbidity of renal insufficiency. How will this patients renal status affect heparin therapy?
Correct!
Incorrect
The correct answer is: C
Rationale
Heparin therapy requires lower doses for patients with renal insufficiency due to reduced clearance of the drug, which increases the risk of bleeding and requires careful monitoring to ensure safety.
A: Heparin is contraindicated in the treatment of this patient. While caution is necessary, heparin is not outright contraindicated; it can be used with adjusted dosing and monitoring.
B: Heparin may be administered subcutaneously, but not IV. Heparin can be administered both subcutaneously and intravenously; the mode of administration does not inherently change based on renal status.
D: Coumadin will be substituted for heparin. Coumadin serves different purposes and cannot simply replace heparin; it requires bridging and is not suitable for immediate anticoagulation in acute settings.

Question 25
Regular
The nurse is assessing a woman who is pregnant at 27 weeks gestation. The patient is concerned about the recent emergence of varicose veins on the backs of her calves. What is the nurses best response?
Correct!
Incorrect
The correct answer is: D
Rationale
Teaching the patient that circulatory changes during pregnancy frequently cause varicose veins provides reassurance and education about a common occurrence, helping her understand that her concern is typical and often temporary.
A: Facilitate a referral to a vascular surgeon. Referring to a specialist may be premature, as many cases of varicose veins during pregnancy resolve postpartum without requiring surgical intervention.
B: Assess the patients ankle-brachial index (ABI) and perform Doppler ultrasound testing. These assessments are unnecessary in this situation, as the emergence of varicose veins is a typical symptom related to pregnancy rather than a vascular disorder.
C: Encourage the patient to increase her activity level. While activity can improve circulation, suggesting it as a primary solution may overlook the normal physiological changes occurring during pregnancy contributing to varicose veins.

Question 26
Regular
Graduated compression stockings have been prescribed to treat a patients venous insufficiency. What education should the nurse prioritize when introducing this intervention to the patient?
Correct!
Incorrect
The correct answer is: D
Rationale
To ensure maximum effectiveness in treating venous insufficiency, the patient must understand that graduated compression stockings should be applied evenly, without creating pressure points that could impede circulation or cause discomfort.
A: The need to take anticoagulants concurrent with using compression stockings. While anticoagulants may be prescribed, they do not directly relate to the application and effectiveness of compression stockings.
B: The need to wear the stockings on a one day on, one day off schedule. This approach undermines the continuous support required for venous insufficiency, limiting the stockings' therapeutic benefits.
C: The importance of wearing the stockings around the clock to ensure maximum benefit. Continuous wear may not be necessary or practical; proper usage focuses on even application rather than constant use.

Question 27
Regular
The nurse caring for a patient with a leg ulcer has finished assessing the patient and is developing a problem list prior to writing a plan of care. What major nursing diagnosis might the care plan include?
Correct!
Incorrect
The correct answer is: D
Rationale
Imbalanced nutrition: less than body requirements. This diagnosis is pertinent as leg ulcers can impair dietary intake and increase metabolic demands, leading to inadequate nutrition, which is crucial for wound healing and recovery.
A: Risk for disuse syndrome. While immobility can be a concern, it does not directly link to a leg ulcer’s nutritional needs, making this option less relevant for the care plan.
B: Ineffective health maintenance. This option addresses broader health management issues but does not specifically focus on the nutritional aspects critical for healing a leg ulcer.
C: Sedentary lifestyle. Although related to activity levels, it does not directly correlate with the nutritional deficits that can exacerbate the healing process of a leg ulcer.

Question 28
Regular
How should the nurse best position a patient who has leg ulcers that are venous in origin?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Elevate the patients lower extremities. Elevating the lower extremities is essential for venous ulcers as it facilitates venous return, reduces swelling, and promotes healing by alleviating pressure on affected areas.
A: Keep the patients legs flat and straight. Maintaining flat and straight legs does not aid venous return and may exacerbate swelling, hindering the healing process for venous ulcers.
B: Keep the patients knees bent to 45-degree angle and supported with pillows. Bending the knees could restrict blood flow and potentially worsen venous congestion, which is counterproductive for ulcer healing.
D: Dangle the patients legs over the side of the bed. Dangling the legs can increase venous pressure and swelling, which may impede healing and worsen the condition of venous ulcers.

Question 29
Regular
A patient with advanced venous insufficiency is confined following orthopedic surgery. How can the nurse best prevent skin breakdown in the patients lower extremities?
Correct!
Incorrect
The correct answer is: A
Rationale
Ensure that the patients heels are protected and supported. This option is essential as it directly addresses the high risk of pressure ulcers in patients with advanced venous insufficiency by providing necessary cushioning and reducing friction on vulnerable areas.
B: Closely monitor the patients serum albumin and prealbumin levels. While important for assessing nutritional status, monitoring these levels does not actively prevent skin breakdown or address the immediate risk factors.
C: Perform gentle massage of the patients lower legs, as tolerated. Massage can potentially aggravate existing venous insufficiency and lead to further skin irritation rather than providing protective benefits against breakdown.
D: Perform passive range-of-motion exercises once per shift. Although beneficial for mobility, these exercises do not specifically target the prevention of skin breakdown, which is a more pressing concern in this scenario.

Question 33
Regular
A nurse is closely monitoring a patient who has recently been diagnosed with an abdominal aortic aneurysm. What assessment finding would signal an impending rupture of the patients aneurysm?
Correct!
Incorrect
The correct answer is: C
Rationale
Sudden onset of severe back or abdominal pain. This symptom often indicates that the aneurysm is stretching or about to rupture, as the body signals distress through acute pain in these areas.
A: Sudden increase in blood pressure and a decrease in heart rate. This combination does not specifically correlate with an impending rupture and could indicate different cardiovascular issues instead.
B: Cessation of pulsating in an aneurysm that has previously been pulsating visibly. While this might suggest changes, it does not directly indicate an impending rupture and could reflect other factors.
D: New onset of hemoptysis. This symptom typically relates to respiratory conditions and does not have a direct association with aortic aneurysm rupture, making it less relevant in this context.
