Rationale: The correct instruction for a patient prescribed hydroxychloroquine, especially in the context of systemic lupus erythematosus (SLE), is to report any vision changes immediately. Hydroxychloroquine can potentially cause retinal damage, so prompt reporting and ophthalmologic evaluation are essential in preventing irreversible eye complications.

Correct Answer: C

Rationale: The correct answer is C: Hemoglobin level. Erythropoietin therapy is used to stimulate red blood cell production in patients with chronic kidney disease who often develop anemia due to reduced erythropoietin production by the kidneys. Monitoring the hemoglobin level is essential to evaluate the effectiveness of erythropoietin therapy as an increase in hemoglobin indicates improved red blood cell production and better management of anemia in these patients. Serum creatinine, white blood cell count, and serum potassium levels are important parameters to monitor in CKD patients but are not specific indicators of the effectiveness of erythropoietin therapy for managing anemia.

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.
