Which is the antibiotic of choice for a bedridden patient with catheter-related UTI and pneumonia?
Show Hint
Resistant organisms make beta-lactamase, so you need an inhibitor combination.
Updated On: Jun 24, 2026
- Amoxicillin
- Beta lactam antibiotic with a beta lactamase inhibitor
- 3rd generation cephalosporins
- 2nd generation cephalosporins

The Correct Option is B
Solution and Explanation
Step 1: Assess the scenario. A bedridden patient with catheter-related UTI plus pneumonia is at risk of resistant, often beta-lactamase-producing organisms.
Step 2: Choose for that resistance. A beta lactam combined with a beta lactamase inhibitor (for example piperacillin-tazobactam or amoxicillin-clavulanate) overcomes beta-lactamase and provides broad coverage of these organisms.
Step 3: Conclude. Option B is the best choice because it pairs potent beta lactam activity with protection against beta-lactamase.
Step 4: Exclude distractors. Plain amoxicillin is destroyed by beta-lactamase, and the cephalosporin options give narrower or less reliable coverage for this mixed, resistance-prone infection.
