Rationale: The correct answer is C. Hydrochlorothiazide is a thiazide diuretic, which can lead to hypokalemia, hyperglycemia, hypercalcemia, hyperlipidemia, and hyperuricemia. It is a sulfa-based medication, so individuals with a sulfa allergy are at risk for an allergic reaction when taking hydrochlorothiazide.

Rationale: Furosemide (Lasix) is a diuretic that can lead to orthostatic hypotension, causing dizziness. Instructing the client to change positions slowly can help prevent this adverse effect. It is important for the client to consume foods rich in potassium to prevent hypokalemia. Taking furosemide in the morning helps reduce the need for frequent urination at night. Encouraging the client to maintain an adequate fluid intake is crucial to prevent dehydration while on this medication.

Correct Answer: B

Rationale: To monitor the effectiveness of infliximab (Remicade) treatment in a client with Crohn's disease, the nurse should observe the frequency and consistency of bowel movements. Infliximab is an immunomodulator that works to reduce inflammation in the colon, leading to improvements in bowel symptoms such as frequency and consistency. Monitoring these bowel patterns can provide valuable insight into the response to the medication and the overall management of Crohn's disease.
