A bed ridden female patient with catheter related UTI by beta lactamase producing Klebsiella pneumoniae. Which of the following drug will you choose?
**Core Concept**
The patient has a catheter-related urinary tract infection (UTI) caused by a beta-lactamase-producing bacterium, Klebsiella pneumoniae, which requires a drug that can overcome beta-lactamase resistance.
**Why the Correct Answer is Right**
The correct choice is a carbapenem antibiotic, specifically imipenem, which has a broad spectrum of activity against Gram-negative bacteria, including Klebsiella pneumoniae. Imipenem is a carbapenem antibiotic that can penetrate the urine and is effective against beta-lactamase-producing bacteria. It works by inhibiting the synthesis of the bacterial cell wall, ultimately leading to bacterial cell death.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not specified, but assuming it's another antibiotic, it might not be effective against beta-lactamase-producing Klebsiella pneumoniae.
**Option B:** This option is not specified, but assuming it's a different antibiotic, it might not have adequate activity against Klebsiella pneumoniae or may not be suitable for urinary tract infections.
**Option C:** This option is not specified, but assuming it's a different antibiotic, it might not be effective against beta-lactamase-producing bacteria or may not penetrate well into the urine.
**Clinical Pearl / High-Yield Fact**
Carbapenems, such as imipenem, are a crucial class of antibiotics for treating UTIs caused by multi-drug resistant bacteria, including those that produce beta-lactamases.
**Correct Answer:** C. Imipenem.
