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 healthcare provider is providing discharge instructions to a client who has a new prescription for warfarin. Which of the following statements should the healthcare provider include?

• A. Avoid using a soft toothbrush.
• B. Report any signs of bleeding.
• C. Increase your intake of leafy green vegetables.
• D. Take the medication with food.

Correct answer: B

Rationale: The correct answer is to instruct the client to report any signs of bleeding when taking warfarin. Warfarin is an anticoagulant medication that increases the risk of bleeding, so it is essential to monitor for any signs of abnormal bleeding and report them promptly for appropriate management. Choices A, C, and D are incorrect. Instructing the client to avoid using a soft toothbrush is not directly related to warfarin therapy. Increasing the intake of leafy green vegetables is not recommended as they contain vitamin K, which can interfere with warfarin's anticoagulant effects. Taking warfarin with food can be inconsistent and may not result in optimal absorption.

3. The LPN/LVN is assisting in the care of a client who has been prescribed enoxaparin (Lovenox) for the prevention of deep vein thrombosis (DVT). Which instruction should the nurse reinforce with the client?

• A. Avoid consuming foods high in vitamin K while taking this medication.
• B. Administer the injection in the same site each time for consistency.
• C. Report any unusual bleeding or bruising to your healthcare provider.
• D. Do not take aspirin if you experience any mild pain or discomfort.

Correct answer: C

Rationale: The correct instruction for the nurse to reinforce with the client is to report any unusual bleeding or bruising to their healthcare provider. This is crucial because unusual bleeding or bruising may indicate excessive anticoagulation, a potential side effect of enoxaparin. Prompt reporting to a healthcare provider is necessary to prevent complications. Choices A, B, and D are incorrect. Choice A is not directly related to enoxaparin and vitamin K interactions. Choice B is incorrect as rotating injection sites is essential for preventing tissue damage and irritation. Choice D is also incorrect as aspirin can increase the risk of bleeding when taken with enoxaparin.

4. A client is wearing a continuous cardiac monitor, which begins to alarm at the nurse's station. The nurse sees no electrocardiographic complexes on the screen. What should the nurse do first?

• A. Call a code blue.
• B. Call the healthcare provider.
• C. Check the client's status and lead placement.
• D. Press the recorder button on the ECG console.

Correct answer: C

Rationale: The correct first action for the nurse to take is to check the client's status and lead placement. This step is crucial to ensure that the alarm is not triggered by a simple issue such as lead displacement. Calling a code blue (choice A) is premature without assessing the client first. Contacting the healthcare provider (choice B) can be done after ruling out basic causes for the alarm. Pressing the recorder button (choice D) is not as urgent as checking the client's status and lead placement in this scenario.

5. A client with a history of coronary artery disease (CAD) is prescribed simvastatin (Zocor). The nurse should teach the client about which potential side effect?

• A. Muscle pain
• B. Dry mouth
• C. Drowsiness
• D. Diarrhea

Correct answer: A

Rationale: Muscle pain is a common side effect of statins like simvastatin and can indicate a serious condition called rhabdomyolysis. Rhabdomyolysis is a severe condition where muscle fibers break down rapidly, releasing myoglobin into the bloodstream, which can lead to kidney damage. Therefore, it's important for the nurse to educate the client about this potential side effect and to promptly report any muscle pain to the healthcare provider. Dry mouth, drowsiness, and diarrhea are not commonly associated with simvastatin use and are less concerning compared to the risk of rhabdomyolysis.
