Nursing Elites

1. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?

• A. Take the medication only when experiencing severe chest pain.
• B. Store the medication in a dark container to protect it from light.
• C. Take the medication before engaging in physical activity that may trigger chest pain.
• D. Limit nitroglycerin use to no more than three doses in 15 minutes.

Correct answer: D

Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.

2. A client with heart failure is prescribed furosemide. The nurse notes that the client's potassium level is 3.1 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement
• B. Encourage the client to eat potassium-rich foods
• C. Hold the next dose of furosemide
• D. Increase the client's fluid intake

Correct answer: A

Rationale: A potassium level of 3.1 mEq/L is considered low, indicating hypokalemia. Administering a potassium supplement is the nurse's priority action to prevent complications such as cardiac arrhythmias associated with low potassium levels. Encouraging the client to eat potassium-rich foods is beneficial in the long term but may not rapidly correct the low potassium level. Holding the next dose of furosemide may worsen the client's heart failure symptoms. Increasing the client's fluid intake is not the priority action in this situation; addressing the low potassium level takes precedence to prevent potential serious complications.

3. After repositioning an immobile client, the nurse observes an area of hyperemia. What action should the nurse take to assess for blanching?

• A. Document the presence in the client’s record.
• B. Apply light pressure over the area.
• C. Apply heat to the area and reassess in 30 minutes.
• D. Apply cold compresses to reduce the redness.

Correct answer: B

Rationale: The correct action for the nurse to take to assess for blanching in an area of hyperemia is to apply light pressure over the area. Blanching is the temporary whitening of the skin when pressure is applied and then released, indicating that the blood flow is returning to the area. Applying light pressure helps in determining if the hyperemic area blanches, ensuring that blood flow is adequate. Choices A, C, and D are incorrect because documenting findings, applying heat, or using cold compresses are not appropriate actions for assessing blanching in an area of hyperemia.

4. While auscultating heart sounds, the nurse hears a swishing sound. How should this sound be documented?

• A. Heart murmur.
• B. Murmur.
• C. S3 sound.
• D. S4 sound.

Correct answer: B

Rationale: The correct answer is B: 'Murmur.' A murmur is a swishing sound heard during auscultation, typically caused by turbulent blood flow through the heart or valves. Choices C and D, 'S3 sound' and 'S4 sound,' refer to specific heart sounds associated with different cardiac conditions, not the general description of a swishing sound. Choice A, 'Heart murmur,' is redundant as 'murmur' alone is sufficient to describe the swishing sound heard.

5. The nurse is caring for a client with an indwelling urinary catheter. Which of the following actions should the nurse prioritize to prevent infection?

• A. Maintain a closed drainage system
• B. Cleanse the catheter insertion site daily
• C. Increase the client's fluid intake
• D. Empty the collection bag every 4 hours

Correct answer: A

Rationale: The correct answer is to maintain a closed drainage system. This action is crucial in preventing infection as it helps prevent bacteria from entering the urinary tract. While cleansing the catheter insertion site and ensuring adequate hydration are important aspects of catheter care, the top priority is maintaining the integrity of the closed system to prevent infection. Emptying the collection bag regularly is also important but not as critical as ensuring a closed drainage system to minimize infection risk.
