Nursing Elites

1. 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.

2. 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.

3. A client presents to the clinic with a large abscess on the right thigh. The healthcare provider incises and drains the abscess. Which instruction should the nurse provide to the client upon discharge?

• A. Avoid showering until the wound is completely closed
• B. Perform daily wound care and dressing changes
• C. Apply heat to the wound for 15 minutes twice a day
• D. Take the prescribed antibiotic until the wound is fully healed

Correct answer: B

Rationale: After incision and drainage of an abscess, it is crucial to perform daily wound care and dressing changes to prevent infection and promote healing. Avoiding showering until the wound is completely closed (choice A) may not be practical or necessary. Applying heat to the wound (choice C) can increase the risk of infection and delay healing. While taking the prescribed antibiotic (choice D) is important, wound care and dressing changes are more directly related to promoting healing and preventing complications.

4. A female client with acute respiratory distress syndrome (ARDS) is sedated and on a ventilator with 50% FIO2. What assessment finding warrants immediate intervention?

• A. Assess the client’s lung sounds bilaterally.
• B. Diminished left lower lobe sounds.
• C. Monitor ventilator settings for changes in oxygen levels.
• D. Increased sputum production and shortness of breath.

Correct answer: B

Rationale: Diminished breath sounds in a sedated client with ARDS and on a ventilator indicate collapsed alveoli, which requires immediate intervention, such as chest tube insertion, to prevent further lung damage. Assessing bilateral lung sounds (Choice A) is important but not as urgent as identifying diminished sounds in a specific location. Monitoring ventilator settings (Choice C) is essential but does not directly address the immediate need for intervention due to diminished breath sounds. Increased sputum production and shortness of breath (Choice D) may indicate other issues but are not specific to the urgency of addressing diminished breath sounds in ARDS.

5. After placing a stethoscope to auscultate S1 and S2 heart sounds, what should the nurse do to check for an S3 heart sound?

• A. Switch to the diaphragm of the stethoscope to hear any abnormal sounds
• B. Listen with the bell of the stethoscope at the same location
• C. Listen at a different location over the aortic area
• D. Switch to the apical area and reassess for S3 sounds

Correct answer: B

Rationale: To assess for an S3 heart sound, the nurse should listen with the bell of the stethoscope. An S3 heart sound is often low-pitched and best heard with the bell. Choice A is incorrect because switching to the diaphragm is not ideal for detecting low-pitched sounds like an S3. Choice C is incorrect as the S3 heart sound is best heard over the apex of the heart, not the aortic area. Choice D is incorrect because moving to the apical area is appropriate, but the nurse should specifically use the bell of the stethoscope to listen for S3 sounds.
