Nursing Elites

1. A client with a history of angina is scheduled for an exercise electrocardiography (ECG) test. The nurse should explain that the purpose of this test is to evaluate which factor?

• A. The heart's response to physical stress
• B. The client's overall physical fitness
• C. The presence of electrolyte imbalances
• D. The effectiveness of anti-anginal medications

Correct answer: A

Rationale: An exercise electrocardiography (ECG) test is used to evaluate the heart's response to physical stress. During the test, the heart's electrical activity is monitored while the client exercises, helping to identify any areas of ischemia or abnormal rhythms. This test helps healthcare providers assess the heart's function and detect any potential issues related to angina or other cardiac conditions. Choice B, the client's overall physical fitness, is incorrect because the test primarily focuses on the heart's response to stress rather than the client's general physical fitness. Choice C, the presence of electrolyte imbalances, is incorrect as this test is not specifically designed to evaluate electrolyte levels. Choice D, the effectiveness of anti-anginal medications, is incorrect as the main purpose of the test is to assess the heart's response to physical stress, not medication effectiveness.

2. The client has atrial fibrillation and is receiving warfarin (Coumadin) therapy. Which laboratory test should be monitored to evaluate the effectiveness of the warfarin therapy?

• A. Prothrombin time (PT) and international normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Complete blood count (CBC)
• D. Fibrinogen levels

Correct answer: A

Rationale: Monitoring the Prothrombin time (PT) and international normalized ratio (INR) is crucial for assessing the effectiveness of warfarin therapy. These tests help determine the clotting ability of the blood and ensure that the client is within the desired therapeutic range to prevent clotting events or bleeding complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy, not warfarin. Complete blood count (CBC) (Choice C) and fibrinogen levels (Choice D) do not directly assess the effectiveness of warfarin therapy in the same way that PT and INR do.

3. A nurse is assessing a client who is taking amiodarone. Which of the following findings should the nurse report to the provider?

• A. Dry skin
• B. Weight loss
• C. Bradycardia
• D. Productive cough

Correct answer: D

Rationale: A productive cough can indicate pulmonary toxicity, a serious side effect of amiodarone, and should be reported. Dry skin is not typically associated with amiodarone use. Weight loss is a common side effect of amiodarone but not generally a cause for concern unless severe. Bradycardia is a known side effect of amiodarone and may not necessarily require immediate reporting unless symptomatic.

4. The healthcare provider is teaching a client about the use of nitroglycerin patches for angina pectoris. Which instruction should the healthcare provider include?

• A. Apply the patch to the same site each day
• B. Remove the patch at bedtime to prevent tolerance
• C. Cover the patch with a bandage to keep it in place
• D. Rotate the application site every 24 hours

Correct answer: D

Rationale: Rotating the application site every 24 hours is crucial when using nitroglycerin patches to prevent skin irritation and ensure consistent absorption of the medication. By rotating the site, the risk of local skin reactions is reduced, and the effectiveness of the nitroglycerin patch is maintained. Applying the patch to the same site each day (Choice A) can lead to skin irritation. Removing the patch at bedtime (Choice B) is not necessary as long as the prescribed wearing schedule is followed. Covering the patch with a bandage (Choice C) is not recommended as it may interfere with proper absorption.

5. The healthcare provider is reinforcing teaching for a client who is starting statin therapy. Which dietary advice should the healthcare provider give?

• A. Eat more whole grains.
• B. Avoid foods high in potassium.
• C. Avoid grapefruit and grapefruit juice.
• D. Increase intake of dairy products.

Correct answer: C

Rationale: The correct answer is C: Avoid grapefruit and grapefruit juice. Grapefruit and grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. It is crucial for clients on statin therapy to avoid grapefruit products to ensure the medication's effectiveness and safety. Choices A, B, and D are incorrect because they do not directly impact the metabolism or effectiveness of statin therapy.
