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 furosemide. Which of the following statements should the nurse include in the teaching?

• A. Take the medication in the morning.
• B. Monitor for muscle weakness.
• C. Eat foods high in potassium.
• D. Expect weight gain.

Correct answer: C

Rationale: The correct statement that the nurse should include in the teaching for a client prescribed furosemide is to eat foods high in potassium. Furosemide can lead to potassium depletion (hypokalemia) due to increased urine output. Consuming potassium-rich foods like bananas, oranges, spinach, and potatoes can help prevent this electrolyte imbalance. Choices A, B, and D are incorrect because taking furosemide in the morning, monitoring for muscle weakness, and expecting weight gain are not directly related to the potential side effects or necessary dietary adjustments when taking furosemide.

3. The client with Raynaud's phenomenon is being taught by the nurse about preventing episodes. Which instruction should the nurse reinforce?

• A. Wear gloves in cold weather.
• B. Avoid caffeine and chocolate.
• C. Increase intake of vitamin C.
• D. Use a heating pad for warmth.

Correct answer: A

Rationale: The correct answer is A: 'Wear gloves in cold weather.' Wearing gloves in cold weather is essential for preventing vasoconstriction and subsequent episodes of Raynaud's phenomenon. Cold temperatures can trigger vasospasms in individuals with Raynaud's, and wearing gloves helps maintain warmth and prevent the constriction of blood vessels in the extremities, reducing the likelihood of an episode. Choices B, C, and D are incorrect because while avoiding caffeine and chocolate, increasing vitamin C intake, and using a heating pad for warmth can be beneficial for overall health, they are not specifically targeted at preventing Raynaud's phenomenon episodes triggered by cold weather.

4. A client with atrial fibrillation is prescribed warfarin (Coumadin). Which instruction should the nurse give to the client regarding lifestyle changes?

• A. Avoid prolonged sitting or standing.
• B. Use an electric razor to prevent cuts.
• C. Take your medication with a full glass of water.
• D. Eat a diet low in protein.

Correct answer: B

Rationale: The correct answer is B. Using an electric razor is advised to prevent cuts, which is crucial for individuals taking warfarin due to the increased risk of bleeding associated with this medication. Lifestyle changes related to warfarin therapy focus on minimizing the risk of bleeding, and using safety measures such as an electric razor is a practical recommendation to reduce the likelihood of injury. Choices A, C, and D are incorrect. Avoiding prolonged sitting or standing is more related to preventing blood clots than to the bleeding risk of warfarin. Taking warfarin with a full glass of water is not a specific lifestyle change associated with its use. Eating a diet low in protein is not a typical recommendation for individuals on warfarin therapy.

5. An 81-year-old male client has emphysema. He lives at home with his cat and manages self-care with no difficulty. When making a home visit, the nurse notices that this client's tongue is somewhat cracked, and his eyeballs appear sunken into his head. Which nursing intervention is indicated?

• A. Help the client determine ways to increase his fluid intake.
• B. Obtain an appointment for the client to have an eye examination.
• C. Instruct the client to use oxygen at night and increase humidification.
• D. Schedule the client for tests to determine his sensitivity to cat hair.

Correct answer: A

Rationale: The client's cracked tongue and sunken eyes indicate dehydration. Therefore, the priority nursing intervention is to help the client determine ways to increase his fluid intake. Dehydration can exacerbate the client's emphysema symptoms and lead to further complications. Monitoring and addressing the client's fluid intake is crucial for maintaining his health and well-being. Options B, C, and D are not the immediate priorities in this situation. While an eye examination, oxygen use, and sensitivity tests are relevant aspects of care, addressing dehydration through increased fluid intake takes precedence in this scenario.
