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. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?

• A. Apply a pressure dressing around the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess for allergies to topical cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.

3. A client with end-stage pulmonary disease requests 'no heroic measures' if she stops breathing. What should the nurse do next?

• A. Document the client's request in the medical record.
• B. Ask the client to discuss a DNR order with her healthcare provider.
• C. Consult the ethics committee for guidance.
• D. Discharge the client with no further discussion.

Correct answer: B

Rationale: The correct next step for the nurse is to ask the client to discuss a 'do not resuscitate' (DNR) order with her healthcare provider. While the client's wishes should be respected, it is essential to ensure proper documentation and legal protection by involving the healthcare provider in this decision-making process. Documenting the request in the medical record (Choice A) is important but should follow the discussion with the healthcare provider. Consulting the ethics committee (Choice C) may not be necessary at this stage and could delay the necessary actions. Discharging the client (Choice D) without further discussion is not appropriate and disregards the importance of addressing the client's wishes in a respectful and professional manner.

4. A client presents with severe dehydration due to prolonged vomiting. What is the nurse's priority intervention?

• A. Encourage the client to drink clear fluids.
• B. Assess the client's skin turgor and mucous membranes.
• C. Monitor the client's vital signs frequently.
• D. Administer an antiemetic as prescribed.

Correct answer: B

Rationale: The correct answer is to assess the client's skin turgor and mucous membranes. When a client presents with severe dehydration, assessing skin turgor (elasticity of the skin) and mucous membranes (such as checking for dryness in the mouth) is crucial in determining the extent of dehydration. Encouraging the client to drink clear fluids (Choice A) may be important but assessing dehydration severity takes precedence. Monitoring vital signs (Choice C) is essential but assessing dehydration status comes first. Administering an antiemetic (Choice D) addresses vomiting but does not directly assess dehydration.

5. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?

• A. Observe rhythm on telemetry monitor.
• B. Check for visual difficulties.
• C. Assess for hip and hand joint pain.
• D. Note the most recent hemoglobin level.

Correct answer: A

Rationale: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.
