1. A client with hepatic encephalopathy is being treated with lactulose. What is an expected outcome of this treatment?
- A. Reduction in blood ammonia levels
- B. Improvement in liver enzyme levels
- C. Decrease in bilirubin levels
- D. Increase in urine output
Correct answer: A
Rationale: Lactulose is used to treat hepatic encephalopathy by reducing blood ammonia levels through promoting its excretion via the intestines. Elevated ammonia levels contribute to the development of encephalopathy symptoms, so by lowering them, the client's neurological status can improve.
2. A client's healthcare provider has ordered a 'liver panel' in response to the client's development of jaundice. When reviewing the results of this laboratory testing, the nurse should expect to review what blood tests? Select one that doesn't apply.
- A. Alanine aminotransferase (ALT)
- B. C-reactive protein (CRP)
- C. Gamma-glutamyl transferase (GGT)
- D. Aspartate aminotransferase (AST)
Correct answer: B
Rationale: A 'liver panel' is a group of blood tests used to evaluate liver function. The components typically include ALT, GGT, and AST. While C-reactive protein (CRP) is a marker of inflammation and not part of a standard liver panel, it may be ordered for other diagnostic purposes.
3. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?
- A. Serum sodium.
- B. Serum potassium.
- C. Serum calcium.
- D. Serum magnesium.
Correct answer: B
Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.
4. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?
- A. To lower blood sugar levels
- B. To reduce ammonia levels
- C. To treat liver inflammation
- D. To improve bile flow
Correct answer: B
Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.
5. A client with a history of chronic alcohol use is admitted with confusion and an unsteady gait. Which deficiency should the nurse suspect?
- A. Thiamine (Vitamin B1)
- B. Cyanocobalamin (Vitamin B12)
- C. Folic acid
- D. Vitamin D
Correct answer: A
Rationale: The correct answer is Thiamine (Vitamin B1). Chronic alcohol use can lead to thiamine deficiency, which can result in neurological symptoms such as confusion and an unsteady gait. Thiamine is essential for proper brain function and nerve conduction, and its deficiency is common in individuals with alcohol use disorder. Cyanocobalamin (Vitamin B12) deficiency can also present with neurological symptoms, but in this case, the patient's history of chronic alcohol use points more towards thiamine deficiency. Folic acid deficiency typically presents with symptoms like fatigue and megaloblastic anemia. Vitamin D deficiency is associated with bone health issues rather than neurological symptoms.
