Nursing Elites

1. The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?

• A. Tall, peaked T waves
• B. ST-segment depression
• C. Prolonged P-R interval
• D. Widening of the QRS complex

Correct answer: B

Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.

2. A client has a new prescription for transdermal nitroglycerin patches. Which of the following instructions should be included for proper use?

• A. Apply the patch to the same site each day.
• B. Place the patch on an area of skin away from skin folds and joints.
• C. Keep the patch on 24 hours per day.
• D. Replace the patch every 72 hours.

Correct answer: B

Rationale: Placing the nitroglycerin patch on an area of skin away from skin folds and joints is crucial to ensure optimal absorption and effectiveness of the medication. Placing the patch on skin folds or joints can interfere with absorption, potentially reducing the patch's efficacy. Therefore, it is essential to follow this instruction to maximize the therapeutic benefits of the nitroglycerin patches. The other options are incorrect because applying the patch to the same site each day can lead to skin irritation, keeping the patch on 24 hours per day may not be necessary depending on the specific patch instructions, and replacing the patch every 72 hours is not the standard frequency for nitroglycerin patches.

3. Prior to a dipyridamole thallium scan, what substance should the LPN/LVN ensure the client has not consumed?

• A. Caffeine
• B. Fatty meal
• C. Excess sugar
• D. Milk products

Correct answer: A

Rationale: Caffeine should be avoided before a dipyridamole thallium scan as it can interfere with the test results. Caffeine is a stimulant that can affect the heart rate and may lead to inaccurate findings during the scan. Fatty meals, excess sugar, and milk products do not specifically interfere with the dipyridamole thallium scan procedure. Therefore, it is essential for the LPN/LVN to check and ensure that the client has not consumed caffeine prior to the procedure to obtain accurate diagnostic results.

4. The nurse is caring for a client with hypertension who is prescribed enalapril (Vasotec). The nurse should monitor the client for which potential adverse effect?

• A. Hypertension
• B. Hypotension
• C. Tachycardia
• D. Hyperglycemia

Correct answer: B

Rationale: The correct answer is B: Hypotension. Enalapril is an ACE inhibitor that works by dilating blood vessels and reducing blood pressure. Therefore, a potential adverse effect of enalapril is hypotension, not hypertension (choice A), tachycardia (choice C), or hyperglycemia (choice D). Monitoring for hypotension is crucial to prevent complications.

5. A healthcare professional is assessing a client who has a new prescription for enalapril. Which of the following findings should the professional report to the provider?

• A. Frequent urination
• B. Dry cough
• C. Tremors
• D. Dizziness

Correct answer: B

Rationale: The correct answer is B: Dry cough. A dry cough is a common side effect of enalapril that can indicate the development of angioedema or potentially life-threatening angioedema. An onset of dry cough should be reported to the provider promptly as it may require discontinuation of the medication to prevent further complications. Frequent urination, tremors, and dizziness are not typically associated with enalapril use and are less likely to be of immediate concern compared to a dry cough in this context.
