Lpn pharmacology I | Nurselytic

Correct Answer: D

Rationale: The correct answer is D. This antibiotic is given as a prophylactic to help reduce the risk of infection after surgery. The rationale is that cefazolin is commonly used as a prophylactic antibiotic before surgery to prevent postoperative infections. By administering it 30 minutes before knee replacement surgery, the nurse is following best practices to reduce the risk of surgical site infections.


Choice A is incorrect because cefazolin is not indicated for replacing vitamins and minerals lost during surgery.
Choice B is incorrect as cefazolin is not a pain medication but an antibiotic.
Choice C is incorrect because cefazolin does not help the surgeon identify areas of bone destruction.

In summary, the correct answer (
D) is supported by the fact that administering cefazolin preoperatively is a standard practice to reduce the risk of infection, while the other choices are incorrect because they do not align with the purpose and mechanism of action of cefazolin.
