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.

The nurse is administering a new medication to a client. What is the priority action before administering the drug?
- A. Verify the client's allergies
- B. Check the client's blood pressure
- C. Assess the client's pain level
- D. Provide client education on the medication
Correct Answer: A
Rationale: Verifying the client's allergies is the priority action before administering any medication. It is crucial to identify any known allergies to prevent potential allergic reactions, which can be severe and life-threatening. Checking the client's blood pressure, assessing pain levels, and providing education on the medication are important aspects of client care but verifying allergies is essential for ensuring the safety of the client.
A client with chronic liver disease is prescribed lactulose. Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
- A. Bilirubin level
- B. Serum ammonia level
- C. Serum potassium level
- D. Albumin level
Correct Answer: B
Rationale: The correct answer is B: Serum ammonia level. Lactulose is used to lower serum ammonia levels in clients with chronic liver disease, particularly in cases of hepatic encephalopathy. Monitoring serum ammonia levels is crucial to evaluate the effectiveness of lactulose in managing hepatic encephalopathy. Choices A, C, and D are incorrect because they are not directly related to the action or evaluation of lactulose in chronic liver disease.
A client presents with three positive responses to the CAGE questionnaire. What interpretation should the nurse provide?
- A. CAGE is a tool for general substance abuse screening.
- B. Two positive responses suggest alcohol dependence.
- C. One positive response does not indicate alcohol addiction.
- D. All four responses must be positive to suggest alcohol dependence.
Correct Answer: B
Rationale: Two positive responses on the CAGE questionnaire strongly suggest alcohol dependence. Choice A is incorrect as the CAGE questionnaire specifically targets alcohol abuse. Choice C is incorrect because one positive response is not enough to indicate alcohol addiction. Choice D is incorrect because alcohol dependence can be suggested with two positive responses, not all four.
A client is admitted to the hospital with a diagnosis of pneumonia. The client is prescribed intravenous antibiotics and oxygen therapy. Which assessment finding indicates that the client's condition is improving?
- A. Increased white blood cell count
- B. Crackles heard on lung auscultation
- C. Productive cough with green sputum
- D. Decreased respiratory rate from 24 to 18 breaths per minute
Correct Answer: D
Rationale: A decrease in respiratory rate indicates that the client's breathing is becoming more stable, which suggests an improvement in their condition. Respiratory rate is a critical indicator of respiratory status and oxygenation. Increased white blood cell count (choice A) suggests ongoing infection, crackles on lung auscultation (choice B) indicate fluid in the lungs, and productive cough with green sputum (choice C) may indicate persistent infection or airway inflammation, which do not necessarily reflect improvement in pneumonia.
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.
