A client diagnosed with a urinary tract infection (UTI) is prescribed sulfamethoxazole/trimethoprim. Which of the following conditions below would be a contraindication for this medication?
Uterine cancer
Client taking captopril for hypertension
Osteoporosis
Multiple Sclerosis
The Correct Answer is B
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.

Correct Answer is ["A","C"]
Explanation
A. Fluoroquinolones: Fluoroquinolones, such as ciprofloxacin and levofloxacin, are known to have the potential to prolong the QT interval, increasing the risk of arrhythmias like Torsades de Pointes.
B. Penicillins: Penicillins do not typically cause QT prolongation. Their adverse effects are more likely to include allergic reactions or gastrointestinal disturbances.
C. Macrolides: Macrolides, such as azithromycin and erythromycin, are associated with QT interval prolongation and an increased risk of cardiac arrhythmias.
D. Beta-Lactams: Beta-lactams, which include penicillins and cephalosporins, are not commonly associated with QT prolongation. They are more likely to cause allergic reactions.
E. Cephalosporins: Cephalosporins are not typically associated with QT prolongation. They share a similar beta-lactam structure to penicillins.
