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 professional is providing discharge teaching to a client who has a new prescription for enoxaparin. Which of the following instructions should the healthcare professional include?

• A. Administer the injection into the abdomen.
• B. Avoid massaging the injection site after administration.
• C. Expect mild bruising at the injection site.
• D. Avoid alternating injection sites between the arms.

Correct answer: A

Rationale: Administering enoxaparin into the abdomen is recommended to ensure proper absorption and effectiveness. Massaging the injection site after administration should be avoided as it can increase the risk of bleeding or bruising. Mild bruising at the injection site is common with enoxaparin and should be expected. Alternating injection sites, especially between arms, is not suitable for enoxaparin administration. Consistent administration into the abdomen is preferred for consistent absorption of the medication.

3. A client with a diagnosis of deep vein thrombosis (DVT) has been placed on bed rest. The LPN/LVN should reinforce which instruction to the client to prevent complications?

• A. Perform ankle pumps and circles every 1 to 2 hours.
• B. Use a heating pad to relieve pain in the affected leg.
• C. Keep the affected leg flat and avoid elevation.
• D. Wear tight compression stockings to prevent swelling.

Correct answer: A

Rationale: Performing ankle pumps and circles every 1 to 2 hours is crucial for a client with DVT on bed rest. These exercises promote venous return, preventing stasis and reducing the risk of complications such as pulmonary embolism. Ankle pumps help activate the calf muscle pump, assisting in propelling blood back to the heart and preventing blood clots from forming or worsening. Choice B is incorrect because using a heating pad can increase blood flow to the area, potentially dislodging a clot. Choice C is incorrect because elevation helps reduce swelling and improve venous return. Choice D is incorrect because although compression stockings can be beneficial, they are not the most important instruction for preventing complications in this scenario.

4. A client diagnosed with hypertension is prescribed atenolol (Tenormin). The nurse should monitor the client for which common side effect of this medication?

• A. Tachycardia
• B. Dry mouth
• C. Hypotension
• D. Increased appetite

Correct answer: C

Rationale: Atenolol is a beta-blocker that works by lowering blood pressure. A common side effect of atenolol is hypotension, where blood pressure drops too low. Therefore, the nurse should monitor the client for signs and symptoms of hypotension to prevent any complications. Choices A, B, and D are incorrect because tachycardia (fast heart rate), dry mouth, and increased appetite are not common side effects of atenolol. Hypotension is the expected side effect due to the medication's mechanism of action.

5. What is the initial action the nurse should take for a client who had a myocardial infarction (MI) and is experiencing restlessness, agitation, and an increased respiratory rate?

• A. Administer oxygen.
• B. Administer morphine sulfate.
• C. Notify the healthcare provider.
• D. Take the client's blood pressure.

Correct answer: A

Rationale: Administering oxygen is the priority action for a client experiencing restlessness, agitation, and an increased respiratory rate after a myocardial infarction (MI). This intervention helps ensure adequate oxygenation, improve cardiac function, and reduce the workload on the heart. Oxygen therapy takes precedence over administering medications like morphine sulfate or notifying the healthcare provider as it addresses the immediate need for oxygenation. Checking the blood pressure is also important but not as urgent as ensuring proper oxygen supply.
