1. How should bleeding in a patient on warfarin be monitored?

A. Monitor INR levels
B. Monitor hemoglobin levels
C. Monitor potassium levels
D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor INR levels. INR levels are the most critical indicator for monitoring bleeding risk in patients on warfarin. INR stands for International Normalized Ratio and specifically measures the clotting tendency of the blood. Monitoring hemoglobin levels, potassium levels, or platelet count are not as directly relevant to assessing bleeding risk in patients on warfarin.

2. A client is receiving chemotherapy and is being taught about preventing infection. Which of the following instructions should the nurse include?

A. Take your temperature daily.
B. Avoid fresh fruits and vegetables.
C. Limit your intake of high-protein foods.
D. Increase your intake of high-fat foods.

Correct answer: B

Rationale: Clients receiving chemotherapy are instructed to avoid fresh fruits and vegetables to lower the risk of infection. Fresh produce may harbor bacteria or other pathogens that could be harmful to individuals with compromised immune systems. Taking the temperature daily may be important but is not directly related to preventing infection. Limiting high-protein foods is not necessary unless there are specific dietary restrictions due to the treatment plan. Increasing the intake of high-fat foods is not recommended during chemotherapy as a high-fat diet may lead to other health issues.

3. Which electrolyte imbalance is most concerning in a patient taking digoxin?

A. Monitor potassium levels
B. Monitor calcium levels
C. Monitor sodium levels
D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

4. A nurse is assessing a client who has pericarditis. Which of the following findings is the priority?

A. Paradoxical pulse
B. Dependent edema
C. Pericardial friction rub
D. Substernal chest pain

Correct answer: A

Rationale: In a client with pericarditis, the priority finding is a paradoxical pulse. This is a crucial sign of cardiac tamponade, a life-threatening complication of pericarditis where fluid accumulates in the pericardial sac, causing compression of the heart. A paradoxical pulse is an exaggerated decrease in systolic blood pressure (>10 mmHg) during inspiration. Prompt recognition and intervention are essential to prevent hemodynamic instability and cardiac arrest. Dependent edema (choice B) is not typically associated with pericarditis. Pericardial friction rub (choice C) is a common finding in pericarditis but does not indicate the urgency of intervention as a paradoxical pulse. Substernal chest pain (choice D) is a classic symptom of pericarditis but is not as critical as a paradoxical pulse in the context of assessing for complications.

5. A healthcare provider is preparing to administer an intramuscular injection to a client. Which of the following sites should the healthcare provider select?

A. Deltoid
B. Vastus lateralis
C. Rectus femoris
D. Dorsogluteal

Correct answer: B

Rationale: The vastus lateralis is the preferred site for intramuscular injections in adults due to its large muscle mass and low risk of complications. The deltoid, although a common site for vaccines, has a smaller muscle mass and may not be suitable for all types of medications. The rectus femoris is a muscle in the thigh that is more commonly used for intramuscular injections in infants. The dorsogluteal site is no longer recommended due to its proximity to major nerves and blood vessels.
