Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. A client with chronic liver disease develops jaundice. What is the most important assessment the nurse should perform?

• A. Assess the client’s skin for lesions or sores.
• B. Monitor the client’s liver function tests.
• C. Assess for changes in mental status and behavior.
• D. Monitor the client’s urine output closely.

Correct answer: D

Rationale: In a client with chronic liver disease developing jaundice, the most important assessment the nurse should perform is to monitor the client’s urine output closely. Jaundice can indicate worsening liver function, so monitoring urine output helps assess kidney function and fluid balance, which are critical in chronic liver disease. Assessing the client’s skin for lesions or sores (Choice A) may be relevant for dermatological conditions but is not the priority in this case. Monitoring liver function tests (Choice B) is important but may not provide immediate information on the client’s current status. Assessing for changes in mental status and behavior (Choice C) is important for detecting hepatic encephalopathy but does not directly address the immediate concern of fluid balance and kidney function in the presence of jaundice.

3. Before administering digoxin to a client with heart failure, what is the most important assessment for the nurse to perform?

• A. Check the client's blood pressure
• B. Monitor the client's heart rate
• C. Assess the client's respiratory rate
• D. Review the client's potassium level

Correct answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.

4. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.

5. A client with hypertension is prescribed hydrochlorothiazide. What teaching should the nurse provide?

• A. Take the medication in the morning to avoid frequent urination at night.
• B. Increase fluid intake to prevent dehydration.
• C. Avoid potassium-rich foods, such as bananas and oranges.
• D. Monitor the client’s potassium levels weekly.

Correct answer: B

Rationale: The correct teaching for a client prescribed hydrochlorothiazide is to increase fluid intake to prevent dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalances, so adequate fluid intake is crucial. Choice A is incorrect because hydrochlorothiazide is typically taken in the morning to avoid nighttime urination. Choice C is incorrect as potassium-rich foods should not be avoided but monitored, as hydrochlorothiazide can cause potassium loss. Choice D is incorrect as potassium levels should be monitored regularly, but not necessarily weekly, unless indicated by the healthcare provider.
