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 with a diagnosis of angina pectoris returns to the nursing unit after experiencing an angioplasty. The nurse reinforces instructions to the client regarding the procedure and home care measures. Which statement by the client indicates an understanding of the instructions?

• A. I am considering cutting my workload.
• B. I need to cut down on cigarette smoking.
• C. I am so relieved that my heart is repaired.
• D. I need to adhere to my dietary restrictions.

Correct answer: D

Rationale: The correct answer is D because adhering to dietary restrictions is crucial in managing heart health post-angioplasty. Choice A focuses on workload, choice B mentions smoking, and choice C reflects relief about heart repair, which are important but do not directly relate to post-angioplasty care instructions.

3. A client with a history of heart failure is admitted with a diagnosis of pulmonary edema. Which intervention should the LPN/LVN expect to assist with first?

• A. Administer a diuretic as prescribed.
• B. Place the client in a high Fowler's position.
• C. Prepare the client for intubation.
• D. Insert an indwelling urinary catheter.

Correct answer: B

Rationale: In a client with pulmonary edema, placing them in a high Fowler's position is the priority intervention. This position helps to improve ventilation and oxygenation by decreasing venous return, reducing the workload on the heart, and facilitating fluid redistribution from the lungs. It is crucial to optimize respiratory function and oxygenation before considering other interventions like administering medications, preparing for intubation, or inserting a urinary catheter. Administering a diuretic, preparing for intubation, or inserting a urinary catheter may be necessary but should follow the priority of improving oxygenation through positioning.

4. A client is diagnosed with thrombophlebitis. The nurse should tell the client that which prescription is indicated?

• A. Bed rest, with bathroom privileges only
• B. Bed rest, keeping the affected extremity flat
• C. Bed rest, with elevation of the affected extremity
• D. Bed rest, with the affected extremity in a dependent position

Correct answer: C

Rationale: The correct answer is C: Bed rest, with elevation of the affected extremity. Elevating the affected extremity is crucial in managing thrombophlebitis as it helps reduce swelling and promotes venous return. By elevating the affected extremity, the gravitational force assists in venous blood flow back to the heart, thereby reducing the risk of complications associated with thrombophlebitis. Choices A, B, and D are incorrect because they do not address the need for elevation, which is specifically beneficial in the management of thrombophlebitis.

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.
