Correct Answer is D

Explanation

Choice A rationale
While antacids can help reduce gastrointestinal discomfort, they do not interact specifically with levofloxacin or affect blood glucose levels.
Choice B rationale
Taking levofloxacin on an empty stomach can enhance absorption, but it does not affect blood glucose levels.
Choice C rationale
Nonsteroidal anti-inflammatory drugs (NSAIDs) can be taken for arthritis pain, but they do not interact specifically with levofloxacin or affect blood glucose levels.
Choice D rationale
Levofloxacin can cause changes in blood glucose levels, so patients with diabetes who are on oral hypoglycemic medication should monitor their blood glucose levels more frequently while on levofloxacin.

A. Collect a urine sample. B. Ensure the patient is on a cardiac monitor. C. Collect a blood culture sample. D. Check baseline vital signs, including temperature.

Correct Answer is C

Explanation

Choice A rationale
While collecting a urine sample can be important in diagnosing certain conditions, it is not the most important action to take prior to administering an antibiotic for pneumonia.
Choice B rationale
Ensuring the patient is on a cardiac monitor is not the most crucial action prior to administering an antibiotic for pneumonia. While it’s important to monitor the patient’s vital signs, it’s not specifically related to the administration of antibiotics.
Choice C rationale
Collecting a blood culture sample is the most important action to take prior to administering an antibiotic for pneumonia. This is to identify the specific bacteria causing the infection, which can help in selecting the most effective antibiotic.
Choice D rationale
Checking baseline vital signs, including temperature, is important but not the most crucial action prior to administering an antibiotic for pneumonia. It’s part of the overall assessment but does not directly impact the choice or effectiveness of the antibiotic.
