Correct Answer is B

Explanation

A. Uterine cancer: No known contraindications exist between this condition and sulfamethoxazole/trimethoprim.

B. Client taking captopril for hypertension: Sulfamethoxazole/trimethoprim can increase potassium levels, and captopril (an ACE inhibitor) also raises potassium levels. Using these drugs together increases the risk of hyperkalemia, a dangerous condition.

C. Osteoporosis: This condition does not contraindicate the use of sulfamethoxazole/trimethoprim.

D. Multiple Sclerosis: No known contraindications exist for this condition with sulfamethoxazole/trimethoprim.

A. Regular sun exposure is needed to maximize drug efficacy B. Avoid water while taking this medication C. Take this medication with antacids to relieve gastrointestinal symptoms D. Avoid dairy products when taking this medication

Correct Answer is D

Explanation

A. Regular sun exposure is needed to maximize drug efficacy: This is incorrect; in fact, doxycycline can cause photosensitivity, and sun exposure should be minimized.

B. Avoid water while taking this medication: Water should be taken with doxycycline to help prevent esophageal irritation.

C. Take this medication with antacids to relieve gastrointestinal symptoms: Antacids can also interfere with doxycycline absorption, so they should be avoided.

D. Avoid dairy products when taking this medication: Dairy products can bind to doxycycline and reduce its absorption in the gastrointestinal tract, which decreases its effectiveness. The client should avoid dairy when taking the medication.
