A client with portosystemic encephalopathy is receiving oral lactulose (Chronulac) daily. The nurse assesses which of the following to determine medication effectiveness?
- A. Lung sounds
- B. Blood pressure
- C. Blood ammonia level
- D. Serum potassium level
Correct Answer: C
Rationale: In portosystemic encephalopathy, the liver's ability to detoxify ammonia is impaired, leading to elevated blood ammonia levels, which can cause neurological symptoms such as encephalopathy. Lactulose is given to reduce ammonia levels by promoting its excretion through the bowel. Therefore, assessing the blood ammonia level is crucial to determine the effectiveness of lactulose therapy in managing portosystemic encephalopathy.

When is the best time for a client to take a daily dose of prednisone?
- A. At noon
- B. At bedtime
- C. Early morning
- D. Anytime, at the same time each day
Correct Answer: C
Rationale: The correct time for a client to take a daily dose of prednisone is early morning. Corticosteroids like prednisone should be taken in the morning to mimic the body's natural hormone release pattern. This timing helps reduce the risk of disrupting the body's internal clock and minimizes the potential for insomnia or other sleep disturbances.
In a client with chronic renal failure receiving epoetin alfa (Epogen, Procrit), which laboratory result would indicate a therapeutic effect of the medication?
- A. Hematocrit of 32%
- B. Platelet count of 400,000 cells/mm³
- C. White blood cell count of 6000 cells/mm³
- D. Blood urea nitrogen (BUN) level of 15 mg/dL
Correct Answer: A
Rationale: A hematocrit of 32% indicates a therapeutic effect of epoetin alfa in a client with chronic renal failure. Epoetin alfa is used to treat anemia in these patients by stimulating red blood cell production, leading to an increase in the hematocrit level. Monitoring the hematocrit is essential to assess the response to epoetin alfa therapy.
