Question 1
Regular
A nurse is caring for a severely burned client who now has elevated hematocrit and blood cell counts. What consequences should the nurse expect in this client?
Correct!
Incorrect
The correct answer is: B
Rationale
Blood clots and kidney stones can be expected in this client due to dehydration and increased blood viscosity from elevated hematocrit, which heightens the risk of thrombus formation and renal complications.
A: Slow heart rate. Elevated hematocrit typically leads to increased blood viscosity, which may cause a faster heart rate as the body compensates for reduced blood flow, rather than a slow heart rate.
C: Imbalance in electrolytes. While burns can lead to electrolyte imbalances, elevated hematocrit specifically indicates fluid loss and concentration of cells, rather than direct changes in electrolyte levels.
D: Elevated central venous pressure (CVP). Increased hematocrit often signifies dehydration, which typically results in decreased blood volume and lower CVP, rather than an elevation in central venous pressure.

Question 2
Regular
The nurse is caring for a client who has been admitted with a possible clotting disorder. The client is complaining of excessive bleeding and bruising without cause. The nurse knows to take extra care to check for signs of bruising or bleeding in what condition?
Correct!
Incorrect
The correct answer is: C
Rationale
Hypocalcemia. This condition results in low calcium levels, which are critical for proper blood clotting. Low calcium can lead to increased bleeding and bruising, necessitating vigilant monitoring by the nurse.
A: Dehydration. While dehydration can cause various complications, it does not directly influence blood clotting mechanisms or significantly contribute to excessive bleeding or bruising in clients.
B: Hypokalemia. This condition refers to low potassium levels, primarily affecting muscle and nerve function, and does not have a direct relationship with bleeding or bruising tendencies.
D: Hypomagnesemia. Low magnesium levels can impact many bodily functions but do not specifically correlate with increased bleeding or bruising, making it an unlikely choice in this context.

Question 3
Regular
The nurse is caring for a client with severe hypokalemia. The physician has prescribed IV potassium to be administered at $10 \mathrm{mEq} / \mathrm{hr}$. The client complains of burning along the vein. What should the nurse do?
Correct!
Incorrect
The correct answer is: A
Rationale
Seek a physician's prescription to dilute the infusion.
Diluting the IV potassium can help reduce irritation and burning sensations along the vein, ensuring a more comfortable administration while maintaining therapeutic efficacy. Proper dilution is crucial for patient safety in hypokalemia treatment.
B: Switch to an oral formulation. Oral potassium may not effectively address severe hypokalemia as rapidly as IV administration, potentially delaying necessary treatment and exposing the patient to further risks.
C: Increase the speed of transfusion. Accelerating the infusion could exacerbate the burning sensation and may lead to complications such as vein irritation or damage, compromising patient safety.
D: Change the electrolyte. Altering the electrolyte type may not address the immediate discomfort experienced from potassium infusion and could divert attention from the urgent need for effective hypokalemia treatment.

Question 4
Regular
The client's lab values are sodium $166 \mathrm{mEq} / \mathrm{L}$, potassium $5.0 \mathrm{mEq} / \mathrm{L}$, chloride $115 \mathrm{mEq} / \mathrm{L}$, and bicarbonate $35 \mathrm{mEq} / \mathrm{L}$. What condition is this client likely to have, judging by anion gap?
Correct!
Incorrect
The correct answer is: A
Rationale
The client is likely to have metabolic acidosis. Elevated bicarbonate levels and a high sodium-to-chloride ratio indicate a compensatory response, suggesting that an underlying metabolic acidosis condition is present.
B: Respiratory alkalosis In this scenario, the lab values do not support respiratory alkalosis, as the bicarbonate level is elevated rather than decreased, contradicting the typical findings for this condition.
C: Metabolic alkalosis The presence of high sodium and chloride levels, along with elevated bicarbonate, does not align with metabolic alkalosis, which typically features low chloride and sodium levels in conjunction with elevated bicarbonate.
D: Respiratory acidosis The lab values reflect metabolic rather than respiratory imbalances; respiratory acidosis presents with elevated carbon dioxide and lower pH, which is inconsistent with the current bicarbonate and electrolyte levels.

Question 5
Regular
The emergency department (ED) nurse is caring for a client with a possible acid- base imbalance. The physician has prescribed an arterial blood gas (ABG). What is one of the most important indications of an acid-base imbalance that is shown in an ABG?
Correct!
Incorrect
The correct answer is: D
Rationale
Bicarbonate is one of the most important indications of an acid-base imbalance shown in an ABG. It plays a crucial role in maintaining pH balance, where abnormal levels indicate metabolic disturbances or compensation mechanisms in the body.
A: $\mathrm{PaO}_2$ Measures oxygen levels in the blood, not directly indicating acid-base status. While important for respiratory function, it does not reflect the acid-base balance specifically.
B: $\mathrm{PO}_2$ Refers to partial pressure of oxygen, which assesses oxygen availability but lacks relevance to the acid-base equilibrium. It does not provide information on bicarbonate levels or pH.
C: Carbonic acid, while involved in the acid-base balance, is not typically measured directly in ABG results. Its levels fluctuate based on carbon dioxide, making it less indicative than bicarbonate.

Question 7
Regular
The nurse is instructing on the body's negative feedback loop to ensure homeostasis to a group of students. Which action by bases keeps the blood $\mathrm{pH}$ nearly neutral?
Correct!
Incorrect
The correct answer is: B
Rationale
Bases bind with hydrogen. This action effectively neutralizes excess acids in the body, maintaining blood pH within the optimal range necessary for physiological processes and overall homeostasis.
A: Bases cast off acids. This description misrepresents the role of bases; they do not release acids but rather interact with them to stabilize pH levels.
C: Bases hold acidic properties. This contradicts the fundamental nature of bases, which are characterized by their ability to neutralize acids rather than possess acidic characteristics themselves.
D: Bases have no contact with acids. This statement overlooks the essential interaction between acids and bases that is crucial for maintaining a balanced pH in the body.

Question 8
Regular
The nurse is caring for an older adult client in the home setting who is experiencing decreased thirst. Which type of fluid imbalance should the nurse anticipate?
Correct!
Incorrect
The correct answer is: A
Rationale
Dehydration
Dehydration is anticipated due to the older adult's decreased thirst, which often leads to reduced fluid intake. In this population, the body's compensatory mechanisms may fail, increasing the risk of fluid imbalance.
B: Hypovolemia
Hypovolemia refers to a decrease in blood volume, often due to significant fluid loss. While related, it does not specifically address the context of decreased thirst impacting fluid intake.
C: Hypervolemia
Hypervolemia indicates an excess of fluid in the body, typically resulting from fluid overload. This scenario contradicts the situation of decreased thirst, which likely leads to fluid deficiency.
D: Third spacing
Third spacing describes fluid accumulation in interstitial spaces, not directly linked to thirst reduction. It involves fluid shifting rather than a decrease in fluid intake from inadequate thirst response.

Question 10
Regular
The nurse is conducting a lecture on the difference between hypovolemia and dehydration. When completing a verbal comparison, which point needs clarified?
Correct!
Incorrect
The correct answer is: C
Rationale
C: In dehydration, only extracellular is depleted. This distinction is crucial as dehydration primarily affects extracellular fluid levels, while hypovolemia involves a reduction in overall blood volume, impacting both extracellular and intravascular compartments.
A: Similar causes are present in both conditions. While some causes may overlap, hypovolemia and dehydration have distinct etiologies that need clarification for accurate diagnosis and treatment.
B: Hypovolemia contains only low blood volume. This statement oversimplifies hypovolemia; it can also involve altered fluid distribution and electrolyte imbalances, not merely low blood volume.
D: Both conditions result in abnormal laboratory studies. Although both may yield abnormal results, the specific laboratory findings differ between hypovolemia and dehydration, necessitating precise diagnostic interpretation.

Question 11
Regular
Which laboratory result does the nurse identify as a direct result of the client's hypovolemic status with hemoconcentration?
Correct!
Incorrect
The correct answer is: B
Rationale
Elevated hematocrit level. Hypovolemic status leads to a decreased plasma volume, which concentrates the red blood cells, resulting in a higher hematocrit. This directly reflects the body’s compensatory mechanisms in response to fluid loss.
A: Abnormal potassium level. Hemoconcentration primarily affects red blood cell levels rather than electrolytes; potassium levels are influenced by various factors unrelated to hypovolemia directly.
C: Low white blood count. Hemoconcentration does not typically decrease white blood cells; rather, it may falsely elevate their concentration due to reduced plasma volume, showing no direct correlation.
D: Low urine specific gravity. Hypovolemia typically results in concentrated urine, leading to a higher specific gravity, as the kidneys conserve water, countering the assumption of lower values.

Question 12
Regular
The nurse is caring for a client in heart failure with signs of hypervolemia. Which vital sign is indicative of the disease process?
Correct!
Incorrect
The correct answer is: B
Rationale
Elevated blood pressure. In heart failure, hypervolemia leads to increased blood volume, which subsequently raises blood pressure as the heart struggles to pump effectively against the excess fluid load.
A: Low heart rate. A decreased heart rate does not align with heart failure symptoms, as the condition typically presents with increased heart rates due to compensatory mechanisms.
C: Rapid respiration. Although rapid respiration can occur in heart failure, it is more indicative of respiratory distress rather than a direct sign of hypervolemia specifically.
D: Subnormal temperature. A lower body temperature does not correlate with heart failure or hypervolemia, which often presents with normal or elevated temperatures due to increased metabolic demands.

Question 15
Regular
Which nursing action is anticipated by the nurse to restore colloidal osmotic pressure to clients with third-spacing?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Initiate an IV of albumin. Administering albumin directly addresses the reduction in colloidal osmotic pressure by increasing the protein concentration in the blood, drawing fluid back into the vascular space and alleviating the symptoms of third-spacing.
A: Initiate an IV of an isotonic solution. While isotonic solutions maintain fluid balance, they do not specifically target the restoration of colloidal osmotic pressure required in third-spacing situations.
C: Manage an infusion of plasma. Infusing plasma may help with volume restoration, but it does not provide the necessary protein concentration to effectively restore colloidal osmotic pressure in third-spacing.
D: Manage an infusion of total parenteral nutrition. Total parenteral nutrition focuses on providing essential nutrients but does not directly address the need for protein to restore colloidal osmotic pressure.

Question 20
Regular
The nurse receives report that a client's $\mathrm{pH}$ level is 7.4. Which nursing action would be most appropriate?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Finish the head-to-toe assessment. A pH level of 7.4 is within the normal range, indicating the client’s acid-base balance is stable. Completing the head-to-toe assessment is essential to gather comprehensive information for ongoing care.
A: Call the health care provider with the report. Reporting a normal pH level does not necessitate immediate communication as the client’s condition appears stable and requires further assessment.
B: Encourage the client to practice deep breathing. While deep breathing can be beneficial, it is unnecessary with a normal pH level; further assessment is more critical to evaluate overall health.
D: Obtain an ECG. A normal pH level does not warrant an ECG. This action is typically reserved for evaluating cardiac issues rather than addressing stable acid-base balance.

Question 21
Regular
The nurse is caring for a client who has been diagnosed with chronic obstructive pulmonary disease (COPD) and is experiencing respiratory acidosis. The client asks what is making the acidotic state. What does the nurse identify as the result of the disease process that causes the fall in $\mathrm{pH}$ ?
Correct!
Incorrect
The correct answer is: D
Rationale
The lungs are not able to regulate carbonic acid levels. In respiratory acidosis, the buildup of carbon dioxide due to impaired lung function leads to an increase in carbonic acid, resulting in a decreased pH.
A: The lungs are unable to breathe in sufficient oxygen. While oxygen intake is crucial, the primary issue in respiratory acidosis is the retention of carbon dioxide, not lack of oxygen.
B: The lungs are unable to exchange oxygen and carbon dioxide. Although gas exchange is compromised, the critical factor in respiratory acidosis is the accumulation of carbon dioxide, affecting pH levels directly.
C: The lungs have ineffective cilia from years of smoking. While ciliary dysfunction contributes to lung problems, it does not directly cause the acidotic state associated with elevated carbon dioxide levels in respiratory acidosis.
Correct Answer: D
Rationale: The lungs are not able to regulate carbonic acid levels. In respiratory acidosis, the buildup of carbon dioxide due to impaired lung function leads to an increase in carbonic acid, resulting in a decreased pH.

B: The lungs are unable to exchange oxygen and carbon dioxide. Although gas exchange is compromised, the critical factor in respiratory acidosis is the accumulation of carbon dioxide, affecting pH levels directly.
C: The lungs have ineffective cilia from years of smoking. While ciliary dysfunction contributes to lung problems, it does not directly cause the acidotic state associated with elevated carbon dioxide levels in respiratory acidosis.
Question 22
Regular
The nurse on a surgical unit is caring for a client recovering from recent surgery with the placement of a nasogastric tube to low continuous suction. Which acid-base imbalance is most likely to occur?
Correct!
Incorrect
The correct answer is: B
Rationale
Metabolic alkalosis. The placement of a nasogastric tube to low continuous suction can lead to the loss of gastric acid, resulting in a higher pH and decreased hydrogen ion concentration, characteristic of metabolic alkalosis.
A: Respiratory alkalosis. This condition typically arises from hyperventilation, which is unrelated to the effects of nasogastric suctioning and does not correlate with the loss of gastric acid.
C: Respiratory acidosis. This imbalance occurs when there is inadequate ventilation leading to carbon dioxide retention, which does not occur with the nasogastric suctioning process described.
D: Metabolic acidosis. This condition results from an excess of acid or loss of bicarbonate, which contrasts with the scenario of gastric acid loss through suctioning that promotes alkalosis instead.

Question 23
Regular
Upon shift report, the nurse states the following laboratory values: $\mathrm{pH}, 7.44 ; \mathrm{PCO}_2, 30 \mathrm{mmHg}$; and $\mathrm{HCO}_3, 21 \mathrm{mEq} / \mathrm{L}$ for a client with noted acid-base disturbances. Which acid-base imbalance do both nurses agree is the client's current state?
Correct!
Incorrect
The correct answer is: A
Rationale
Compensated respiratory alkalosis. The laboratory values indicate a pH above normal, low PCO2, and normal HCO3 levels, suggesting that the respiratory system has compensated for the alkalosis through hyperventilation, balancing the acid-base status.
B: Uncompensated respiratory alkalosis. The PCO2 is significantly low, indicating respiratory compensation, which shows that the condition is not uncompensated but rather compensated for the alkalosis.
C: Compensated metabolic acidosis. The HCO3 level is low, which is inconsistent with metabolic acidosis; thus, this option does not reflect the respiratory origin of the imbalance.
D: Compensated metabolic alkalosis. The pH and HCO3 levels do not support metabolic alkalosis, as the low PCO2 indicates that the issue stems from respiratory, not metabolic, disturbances.

Question 24
Regular
The nurse is caring for a client prescribed a low sodium diet. Which food, identified as a client favorite, will the nurse discourage?
Correct!
Incorrect
The correct answer is: C
Rationale
C: A hot dog with ketchup. Hot dogs are typically high in sodium due to added preservatives and flavoring agents, making them unsuitable for a client following a low sodium diet.
A: A grilled chicken sandwich with mayonnaise. While mayonnaise can contain some sodium, grilled chicken is generally a low-sodium option, especially if prepared without added salt.
B: A natural fruit salad with nuts. Fruit salads are typically low in sodium, and nuts can be chosen in unsalted varieties, making this option more suitable for sodium-restricted diets.
D: A fresh grilled tuna entrée with fresh asparagus. Tuna can be a low-sodium food when prepared without added salt, and asparagus is naturally low in sodium, making this meal appropriate.

Question 25
Regular
The nurse is caring for a client with laboratory values indicating dehydration. Which clinical symptom is consistent with the dehydration?
Correct!
Incorrect
The correct answer is: D
Rationale
Dark, concentrated urine. This symptom indicates the body's attempt to conserve water due to dehydration, resulting in urine that has a deeper color and higher specific gravity compared to normal hydration levels.
A: Cool and pale skin. This symptom typically suggests reduced blood circulation or shock, rather than dehydration specifically, and does not directly correlate with the body's fluid status.
B: Crackles in the lung fields. This finding points to fluid accumulation in the lungs, which is associated with conditions like heart failure, rather than the effects of dehydration.
C: Distended jugular veins. This symptom indicates increased blood volume or pressure in the venous system, which contrasts with dehydration's effects that typically lead to decreased vascular volume.

Question 26
Regular
The nurse is caring for a client with frequent dizziness. The nurse is evaluating the client for postural hypotension. Which of the following symptoms would indicate a potential diagnosis?
Correct!
Incorrect
The correct answer is: B
Rationale
A drop in systolic blood pressure $(15 \mathrm{~mm} \mathrm{Hg}$ ) upon rising indicates postural hypotension, as it reflects the body's inadequate response to changes in position, potentially causing dizziness.
A: A blood pressure elevation upon activity signifies an increase in vascular resistance, typically associated with exertion rather than a drop indicative of postural hypotension.
C: A pulsating headache does not directly relate to postural hypotension, as headaches can arise from numerous other factors unrelated to blood pressure changes upon standing.
D: A drop in diastolic blood pressure $(25 \mathrm{mmHg}$ ) upon rising is not a standard indicator for postural hypotension, where systolic changes are more clinically significant in assessing the condition.

Question 27
Regular
An adult client is brought into the clinic feeling thirsty with dry, sticky mucous membranes; decreased urine output; fever; a rough tongue; and lethargy. The nurse reconciles the client's medication list and notes that salt tablets had been prescribed. What would the nurse do next?
Correct!
Incorrect
The correct answer is: D
Rationale
Discontinuing salt tablets is essential due to the client's symptoms of dehydration and electrolyte imbalance. The presence of thirst, dry mucous membranes, and lethargy indicates that sodium levels may be elevated, necessitating sodium restriction.
A: Continue to monitor client with another appointment. This option fails to address the immediate need for intervention regarding the client’s dehydration and potential hypernatremia.
B: Be prepared to administer a lactated Ringer's IV. While IV fluids may be necessary, lactated Ringer's does not specifically address the excess sodium issue present in this scenario.
C: Be prepared to administer a sodium chloride IV. Administering sodium chloride would exacerbate the client’s condition, as their symptoms indicate a need for sodium restriction, not supplementation.

Question 28
Regular
A client with hypervolemia asks the nurse what mechanism in the sodium potassium pump will move the excess body fluid. What is the correct answer from the nurse?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Active transport. The sodium-potassium pump utilizes active transport to move sodium out of cells and potassium in, which helps regulate fluid balance and mitigate the effects of hypervolemia by controlling extracellular fluid volume.
A: Passive osmosis. This process involves the movement of water across a membrane, driven by concentration gradients, but does not directly address the active regulation of sodium and potassium levels.
B: Free flow. This term implies an unrestricted movement of fluids, lacking the specificity needed to explain the mechanisms of fluid balance and cellular ion regulation relevant to hypervolemia.
C: Passive elimination. While it suggests removal of excess fluid, it fails to capture the active role of the sodium-potassium pump in managing electrolyte balance and fluid distribution within the body.

Question 29
Regular
A nurse is assessing a client's reflexes. Which condition does the nurse need to confirm when tapping the facial nerve of a client who has dysphagia?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Hypomagnesemia. Hypomagnesemia can affect neuromuscular function, leading to altered reflex responses. In clients with dysphagia, confirming hypomagnesemia is crucial as it could exacerbate swallowing difficulties and reflex abnormalities.
A: Hypervolemia. Hypervolemia primarily involves excess fluid volume, which does not directly impact the facial nerve reflexes or swallowing capabilities in the context of dysphagia assessment.
B: Hypercalcemia. Hypercalcemia is usually related to increased calcium levels, which can lead to various symptoms but does not specifically correlate with the assessment of facial nerve reflexes in dysphagia.
D: Hypermagnesemia. Hypermagnesemia can cause neuromuscular impairment, but the condition is less relevant in assessing reflexes related to facial nerve function in patients experiencing dysphagia.

Question 30
Multiple Choice
A client was admitted to the unit with a diagnosis of hypovolemia. When it is time to complete discharge teaching, which of the following will the nurse teach the client and family? Select all that apply.
Correct!
Incorrect
The correct answer is: A,D,E
Rationale
Drink at least eight glasses of fluid each day, drink water as an inexpensive way to meet fluid needs, and respond to thirst are essential teaching points for managing hypovolemia. These actions help ensure adequate hydration and fluid balance, crucial for recovery and maintaining optimal health following a diagnosis of low blood volume.
B: Drink caffeinated beverages to retain fluid. Caffeine acts as a diuretic, potentially leading to increased fluid loss rather than retention, which is counterproductive for someone with hypovolemia.
C: Drink alcoholic beverages to help balance fluid volume. Alcohol can dehydrate the body and worsen fluid imbalances, making it unsuitable for someone recovering from hypovolemia.
E: Respond to thirst. Ignoring thirst can lead to inadequate fluid intake, which is critical for someone with hypovolemia, as thirst is a natural indicator of hydration needs.
