Nursing Elites

1. The nurse is caring for a client on digoxin. What is the most important assessment before administering this medication?

• A. Check the client’s heart rate.
• B. Check the client’s blood pressure.
• C. Check the client’s respiratory rate.
• D. Check the client’s oxygen saturation.

Correct answer: A

Rationale: The correct answer is to check the client’s heart rate before administering digoxin because one of the side effects of digoxin is bradycardia. Monitoring the heart rate is crucial to assess whether the client's heart rate is within the acceptable range before giving the medication. Checking the blood pressure (Choice B), respiratory rate (Choice C), or oxygen saturation (Choice D) are important assessments in general patient care, but they are not specifically related to the administration of digoxin.

2. What is a condition where the arteries that supply blood to the heart muscle become hardened and narrowed due to the buildup of plaque?

• A. Atherosclerosis
• B. Aneurysm
• C. Arrhythmia
• D. Peripheral artery disease

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It is a condition characterized by the hardening and narrowing of arteries supplying blood to the heart due to plaque buildup. This condition increases the risk of heart attacks. Choice B, aneurysm, refers to a balloon-like bulge in an artery, not the hardening and narrowing of arteries. Choice C, arrhythmia, is an irregular heartbeat and not related to arterial hardening. Choice D, peripheral artery disease, involves the narrowing of arteries that supply blood to the limbs, not specifically to the heart.

3. What type of imaging test uses X-rays to visualize the blood vessels after injecting them with a contrast dye?

• A. Angiography
• B. CT scan
• C. MRI
• D. Ultrasound

Correct answer: A

Rationale: Angiography is the correct answer because it is an imaging test that specifically uses X-rays to visualize blood vessels by injecting them with a contrast dye. This procedure is crucial for diagnosing conditions such as blockages or aneurysms. The other options, CT scan, MRI, and ultrasound, do not involve the use of contrast dye to visualize blood vessels with X-rays.

4. The client is on nitroglycerin patches. What should the nurse include in the client’s education?

• A. Rotate the application site with each new patch.
• B. Apply the patch at the same time each day.
• C. Leave the patch on for 24 hours, then remove it for 12 hours before applying a new one.
• D. Apply the patch to the same site each time.

Correct answer: A

Rationale: The correct answer is A: 'Rotate the application site with each new patch.' When educating a client using nitroglycerin patches, it is essential to rotate the application site to prevent skin irritation. Choice B is incorrect because applying the patch at the same time each day is not a critical aspect of patch application. Choice C is incorrect as nitroglycerin patches are usually left on for a specific period, typically 12 to 14 hours, before being replaced. Choice D is incorrect because applying the patch to the same site each time can lead to skin irritation and tolerance development.

5. What is a condition where the heart is unable to relax properly between beats, reducing its ability to fill with blood?

• A. Diastolic heart failure
• B. Systolic heart failure
• C. Hypertrophic cardiomyopathy
• D. Restrictive cardiomyopathy

Correct answer: A

Rationale: The correct answer is A: Diastolic heart failure. In diastolic heart failure, the heart is unable to relax properly between beats, leading to a reduced ability to fill with blood. This condition primarily affects the heart's filling function rather than its pumping function, which is characteristic of systolic heart failure (choice B). Hypertrophic cardiomyopathy (choice C) involves the abnormal thickening of the heart muscle, while restrictive cardiomyopathy (choice D) is characterized by the heart muscle becoming stiff and less compliant. Therefore, choices B, C, and D are incorrect in the context of a heart condition where relaxation between beats is impaired.
