Nursing Elites

1. The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?

• A. Administer a potassium supplement
• B. Notify the healthcare provider
• C. Hold the next dose of digoxin
• D. Increase dietary potassium intake

Correct answer: C

Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

2. The client is being taught to choose foods rich in potassium to prevent digitalis toxicity. Which choice indicates the client understands dietary needs?

• A. Three apricots
• B. Medium banana
• C. Naval orange
• D. Baked potato

Correct answer: D

Rationale: The correct answer is D: Baked potato. Baked potatoes are rich in potassium, which is essential in preventing digitalis toxicity by helping to maintain normal electrolyte levels. Apricots, bananas, and oranges are also sources of potassium, but a baked potato has a higher potassium content compared to the other options, making it a more effective choice for preventing digitalis toxicity.

3. The nurse is taking the blood pressure measurement of a client with Parkinson's disease. Which information in the client's admission assessment is relevant to the nurse's plan for taking the blood pressure reading?

• A. Frequent syncope
• B. Muscle rigidity
• C. Gait instability
• D. Fine motor tremors

Correct answer: A

Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.

4. Which intervention should be included in the long-term plan of care for a client with COPD?

• A. Administer high-flow oxygen during sleep.
• B. Reduce risk factors for infection.
• C. Limit fluid intake to reduce secretions.
• D. Use diaphragmatic breathing to achieve better exhalation.

Correct answer: D

Rationale: The correct answer is D: 'Use diaphragmatic breathing to achieve better exhalation.' Diaphragmatic breathing is an essential intervention for clients with COPD as it helps improve exhalation and lung function, ultimately reducing symptoms over the long term. Option A is incorrect because high-flow oxygen during sleep is more relevant for clients with conditions like sleep apnea rather than COPD. Option B, 'Reduce risk factors for infection,' is important but not as specific to the long-term management of COPD as diaphragmatic breathing. Option C, 'Limit fluid intake to reduce secretions,' is not a recommended intervention for clients with COPD, as adequate hydration is crucial for maintaining respiratory health.

5. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.
