Question 1
Regular
A nurse is caring for a patient who has sickle cell anemia and the nurses assessment reveals the possibility of substance abuse. What is the nurses most appropriate action?
Correct!
Incorrect
The correct answer is: B
Rationale
Encouraging the patient to seek care from a single provider for pain relief is the most appropriate action. This approach fosters continuity of care, enhances the management of pain, and minimizes the risk of substance misuse, ensuring a more controlled treatment plan for the patient’s sickle cell anemia.
A: Encourage the patient to rely on complementary and alternative therapies. While these therapies can be beneficial, they should not replace conventional pain management, especially in patients with chronic conditions like sickle cell anemia.
C: Teach the patient to accept chronic pain as an inevitable aspect of the disease. This perspective can hinder effective pain management and discourage proactive treatment, ultimately compromising the patient's quality of life.
D: Limit the reporting of emergency department visits to the primary health care provider. Concealing such visits undermines coordinated care, may exacerbate substance abuse issues, and does not support effective pain management strategies.

Question 2
Regular
A patient newly diagnosed with thrombocytopenia is admitted to the medical unit. After the admission assessment, the patient asks the nurse to explain the disease. What should the nurse explain to this patient?
Correct!
Incorrect
The correct answer is: B
Rationale
Thrombocytopenia may occur due to decreased production of platelets in the bone marrow, leading to a reduced number of these essential blood cells, which are crucial for normal clotting and maintaining hemostasis.
A: There could be an attack on the platelets by antibodies. This statement describes immune-mediated thrombocytopenia but does not address the common cause of decreased production, making it less relevant.
C: There could be impaired communication between platelets. While communication is important for platelet function, thrombocytopenia primarily results from a reduction in platelet numbers rather than communication issues.
D: There could be an autoimmune process causing platelet malfunction. This option pertains to specific types of thrombocytopenia, but it does not encompass the broader, more prevalent cause of decreased platelet production.

Question 3
Regular
A critical care nurse is caring for a patient with autoimmune hemolytic anemia. The patient is not responding to conservative treatments, and his condition is now becoming life threatening. The nurse is aware that a treatment option in this case may include what?
Correct!
Incorrect
The correct answer is: D
Rationale
Splenectomy
In cases of autoimmune hemolytic anemia, splenectomy can be a critical intervention as the spleen plays a significant role in the destruction of red blood cells. Removing the spleen may alleviate the hemolytic process and improve the patient's condition, especially when conservative treatments fail and life-threatening situations arise.
A: Hepatectomy This procedure involves the removal of the liver, which does not address the underlying issue of hemolysis in autoimmune hemolytic anemia and is unrelated to the patient’s condition.
B: Vitamin K administration This treatment is primarily used for clotting disorders and does not target the autoimmune response causing hemolytic anemia, making it ineffective in this particular scenario.
C: Platelet transfusion While platelet transfusions can be beneficial for low platelet counts, they do not influence red blood cell destruction in hemolytic anemia, rendering this option unsuitable for the patient’s needs.

Question 4
Regular
A nurse is providing education to a patient with iron deficiency anemia who has been prescribed iron supplements. What should the nurse include in health education?
Correct!
Incorrect
The correct answer is: C
Rationale
Iron will cause the stools to darken in color. This is a common and harmless side effect of iron supplementation, which helps patients understand what changes to expect while managing their anemia treatment. Awareness can alleviate concerns about unexpected changes during therapy, reinforcing adherence to prescribed iron supplements.
A: Take the iron with dairy products to enhance absorption. Dairy products contain calcium, which inhibits iron absorption rather than enhancing it, potentially reducing the effectiveness of the supplements.
B: Increase the intake of vitamin E to enhance absorption. Vitamin E does not significantly impact iron absorption; instead, vitamin C is known to improve iron uptake, making this option misleading.
D: Limit foods high in fiber due to the risk for diarrhea. While fiber is important for digestive health, it does not directly cause diarrhea when taken with iron supplements; it can actually promote regular bowel movements.

Question 5
Regular
The nurse is assessing a new patient with complaints of overwhelming fatigue and a sore tongue that is visibly smooth and beefy red. This patient is demonstrating signs and symptoms associated with what form of what hematologic disorder?
Correct!
Incorrect
The correct answer is: C
Rationale
Megaloblastic anemia is the correct answer. This condition is characterized by the presence of a smooth, beefy red tongue and overwhelming fatigue, commonly due to vitamin B12 or folate deficiencies affecting red blood cell production.
A: Sickle cell anemia involves abnormal hemoglobin leading to painful crises and anemia, but does not typically present with a smooth, beefy red tongue or specific fatigue symptoms.
B: Hemophilia primarily manifests through prolonged bleeding and bruising, lacking the characteristic smooth tongue and fatigue seen in the patient’s presentation, making it unrelated to the symptoms described.
D: Thrombocytopenia results in low platelet counts, leading to easy bruising and bleeding, but does not cause the smooth tongue or the severe fatigue experienced by the patient.

Question 6
Regular
A patient with renal failure has decreased erythropoietin production. Upon analysis of the patients complete blood count, the nurse will expect which of the following results?
Correct!
Incorrect
The correct answer is: B
Rationale
A decreased hemoglobin and hematocrit. In renal failure, the reduction in erythropoietin production leads to insufficient red blood cell production, resulting in lower levels of hemoglobin and hematocrit in the complete blood count.
A: An increased hemoglobin and decreased hematocrit. This scenario contradicts the expected findings since low erythropoietin would not cause increased hemoglobin levels or altered hematocrit.
C: A decreased mean corpuscular volume (MCV) and red cell distribution width (RDW). Renal failure typically does not lead to a decrease in MCV or RDW; instead, values may remain normal or increase due to anemia.
D: An increased MCV and RDW. An increase in these parameters does not align with decreased erythropoietin levels, which generally result in normocytic anemia rather than macrocytic changes reflected in MCV and RDW.
Correct Answer: B

Question 7
Regular
A patient comes to the clinic complaining of fatigue and the health interview is suggestive of pica. Laboratory findings reveal a low serum iron level and a low ferritin level. With what would the nurse suspect that the patient will be diagnosed?
Correct!
Incorrect
The correct answer is: A
Rationale
Iron deficiency anemia. The patient’s symptoms of fatigue, combined with the low serum iron and ferritin levels, strongly indicate a deficiency in iron, leading to the diagnosis of iron deficiency anemia.
B: Pernicious anemia. This condition is characterized by vitamin B12 deficiency, not iron levels, making it an unlikely diagnosis in the context of low iron and ferritin findings.
C: Sickle cell anemia. Sickle cell anemia involves abnormal hemoglobin and primarily presents with pain and crises, rather than the fatigue and low iron levels observed in this patient.
D: Hemolytic anemia. This type of anemia is caused by the destruction of red blood cells, which does not align with the low iron and ferritin levels indicating a deficiency rather than destruction.

Question 8
Regular
A patient comes into the clinic complaining of fatigue. Blood work shows an increased bilirubin concentration and an increased reticulocyte count. What would the nurse suspect the patient has?
Correct!
Incorrect
The correct answer is: D
Rationale
A hemolytic anemia. Increased bilirubin indicates the breakdown of red blood cells, while a heightened reticulocyte count suggests the bone marrow's response to anemia, characteristic of hemolytic conditions.
A: A hypoproliferative anemia. This condition involves insufficient red blood cell production, which would not typically present with elevated bilirubin or reticulocyte counts.
B: A leukemia. Leukemia primarily affects white blood cells and does not directly correlate with increased bilirubin levels or a significant reticulocyte response indicating hemolysis.
C: Thrombocytopenia. This condition refers to low platelet counts and does not relate to bilirubin concentration or reticulocyte levels, making it unrelated to hemolytic anemia.

Question 9
Regular
A nurse is caring for a patient with severe anemia. The patient is tachycardic and complains of dizziness and exertional dyspnea. The nurse knows that in an effort to deliver more blood to hypoxic tissue, the workload on the heart is increased. What signs and symptoms might develop if this patient goes into heart failure?
Correct!
Incorrect
The correct answer is: A
Rationale
Peripheral edema. In heart failure, the heart's inability to pump effectively leads to fluid accumulation in tissues, causing swelling, especially in the extremities. This symptom reflects the body's response to poor circulation and increased pressure in blood vessels.
B: Nausea and vomiting. While these symptoms can occur, they are not direct indicators of heart failure. They may arise from other causes, such as medication side effects or gastrointestinal issues.
C: Migraine. Migraines are primarily neurological conditions and do not relate to heart failure. They stem from different mechanisms, typically involving vascular changes in the brain rather than cardiac dysfunction.
D: Fever. Fever indicates infection or inflammation and is not typically associated with heart failure. Heart failure symptoms arise from circulatory issues rather than infectious processes that would elevate body temperature.

Question 11
Regular
A patients blood work reveals a platelet level of 17,000/mm3. When inspecting the patients integumentary system, what finding would be most consistent with this platelet level?
Correct!
Incorrect
The correct answer is: B
Rationale
Petechiae
A platelet level of 17,000/mm3 indicates severe thrombocytopenia, which often leads to the formation of petechiae—small, pinpoint hemorrhages in the skin resulting from capillary bleeding due to insufficient platelets for clotting.
A: Dermatitis
Dermatitis refers to inflammation of the skin typically caused by irritants or allergens, not directly associated with low platelet counts or bleeding abnormalities in the integumentary system.
C: Urticaria
Urticaria, or hives, presents as raised welts on the skin, primarily linked to allergic reactions, rather than directly related to the low platelet level and its bleeding manifestations.
D: Alopecia
Alopecia involves hair loss and does not correlate with platelet levels, as it primarily stems from autoimmune conditions or genetic factors unrelated to thrombocytopenia and bleeding tendencies.

A nurse is planning the care of a patient with a diagnosis of sickle cell disease who has been admitted for the treatment of an acute vaso-occlusive crisis. What nursing diagnosis should the nurse prioritize in the patient's plan of care?
Correct!
Incorrect
The correct answer is: C
Rationale
Ineffective tissue perfusion related to thrombosis. This diagnosis is prioritized as the acute vaso-occlusive crisis in sickle cell disease directly leads to reduced blood flow and oxygen delivery to tissues, causing pain and potential organ damage.
A: Risk for disuse syndrome related to ineffective peripheral circulation. While circulation issues are relevant, this diagnosis does not specifically address the acute crisis impacting tissue perfusion and pain management.
B: Functional urinary incontinence related to urethral occlusion. This diagnosis does not relate to the primary concerns of the vaso-occlusive crisis, which focuses on pain and tissue oxygenation rather than urinary function.
D: Ineffective thermoregulation related to hypothalamic dysfunction. This option is not pertinent in the context of sickle cell crisis management, as the primary focus is on tissue perfusion, not temperature regulation.

Question 22
Regular
A patient is being treated on the medical unit for a sickle cell crisis. The nurse's most recent assessment reveals an oral temperature of 100.5┬░F and a new onset of fine crackles on lung auscultation. What is the nurse's most appropriate action?
Correct!
Incorrect
The correct answer is: D
Rationale
Inform the primary care provider that the patient may have an infection.
The patient's elevated temperature and new crackles suggest a possible infection, especially in the context of sickle cell disease, which predisposes individuals to pulmonary complications. Prompt communication with the primary care provider is essential for timely intervention and management of any potential infection, ensuring appropriate treatment is initiated without delay.
A: Apply supplementary oxygen by nasal cannula. While oxygen may be beneficial, it does not address the potential underlying infection indicated by the patient's symptoms, which requires immediate attention.
B: Administer bronchodilators by nebulizer. Although bronchodilators can assist with respiratory issues, they do not target the likely infection suggested by the patient's fever and lung findings, which must be prioritized.
C: Liaise with the respiratory therapist and consider high-flow oxygen. High-flow oxygen may be necessary later, but the immediate concern is determining the cause of the new crackles and fever, indicating potential infection.

Question 30
Regular
A patient with a recent diagnosis of ITP has asked the nurse why the care team has not chosen to administer platelets, stating, â??I have low platelets, so why not give me a transfusion of exactly what I'm missing?â?? How should the nurse best respond?
Correct!
Incorrect
The correct answer is: A
Rationale
Transfused platelets usually aren't beneficial because they're rapidly destroyed in the body. In ITP, the immune system targets and eliminates transfused platelets quickly, rendering such transfusions ineffective for increasing platelet counts in patients.
B: A platelet transfusion often blunts your body's own production of platelets even further. This statement misrepresents the primary issue, which is the destruction of transfused platelets rather than suppression of natural production.
C: Finding a matching donor for a platelet transfusion is exceedingly difficult. While matching can be complex, the primary reason for not transfusing platelets in ITP relates to their rapid destruction, not donor compatibility.
D: A very small percentage of the platelets in a transfusion are actually functional. This claim overlooks the key issue in ITP, which is that transfused platelets are quickly targeted and eliminated by the immune system.

Correct Answer: D
Rationale: The patient's activated partial thromboplastin time (aPTT) is 1.5 to 2.5 times the control value. This finding indicates that the heparin infusion is effectively prolonging the clotting time, demonstrating adequate anticoagulation necessary for treating pulmonary embolism.
A: The patient's PT is within reference ranges. This measurement primarily reflects the effectiveness of warfarin, not heparin, making it an unsuitable indicator of heparin treatment efficacy.
B: Arterial blood sampling tests positive for the presence of factor XIII. Factor XIII's presence does not provide any relevant information regarding the effectiveness of heparin therapy in managing pulmonary embolism.
C: The patient's platelet level is below 100,000/mm3. Thrombocytopenia may indicate heparin-induced thrombocytopenia, a complication rather than a sign of effective treatment, providing no assurance of therapeutic success.
