The nurse is preparing to administer the first dose of an antibiotic to a patient admitted for pneumonia. What is the most important action to take prior to administering the antibiotic?

Collect a urine sample.

Ensure the patient is on a cardiac monitor.

Collect a blood culture sample.

Check baseline vital signs, including temperature.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

Choice A rationale
While a fasting blood sugar level of 130 mg/dL is slightly elevated, it is not the most concerning finding given the current medications. Metformin is a medication used to control blood sugar levels in patients with diabetes, so this patient’s blood sugar is being managed.
Choice B rationale
Yellow discoloration of the sclera is a sign of jaundice, which can indicate liver damage. Given that this patient is taking several medications that can potentially cause liver damage (including isoniazid and acetaminophen), this finding is most concerning.
Choice C rationale
A positive result on the tuberculin skin test indicates exposure to tuberculosis, but it does not necessarily mean the patient has active tuberculosis. The patient is currently taking medications for tuberculosis (isoniazid and rifampin), indicating that this condition is being managed.
Choice D rationale
A blood pressure reading of 100/70 mmHg is within the normal range, so this would not be the most concerning finding. The patient’s metoprolol medication is used to manage blood pressure, indicating that this aspect of the patient’s health is being managed. Prednisone Prednisone Explore

A. When the client feels nauseous or vomits B. Immediately after the chemotherapy is complete C. 30 minutes prior to starting the chemotherapy D. When the client requests the ondansetron

Correct Answer is C

Explanation

Choice A rationale
Administering ondansetron when the client feels nauseous or vomits is not the most effective use of the medication. The goal is to prevent nausea and vomiting from occurring in the first place.
Choice B rationale
Administering ondansetron immediately after chemotherapy is complete may not provide the most effective prevention of nausea and vomiting. The medication needs time to work and should ideally be administered before chemotherapy begins.
Choice C rationale
The optimal time to administer ondansetron is 30 minutes prior to starting chemotherapy. This allows the medication to start working before the chemotherapy drugs that cause nausea and vomiting are administered.
Choice D rationale
While it’s important to respond to a client’s requests, waiting until the client requests the ondansetron may not prevent the onset of nausea and vomiting. It’s more effective to administer the medication proactively.
