How would the nurse best evaluate the effectiveness of drug therapy for a client diagnosed with pneumonia being treated with amoxicillin?

Oral temperature of 100.6°F.

Pulse oximetry of 98% on room air.

Increased neutrophil count.

Adequate urine output.

Answer and Explanation

The Correct Answer is B

Choice A Reason

An oral temperature of 100.6°F may indicate that the client still has a fever, which could suggest ongoing infection. However, temperature alone is not the most reliable indicator of the effectiveness of antibiotic therapy, as it can be influenced by various factors.

Choice B Reason

Pulse oximetry measures the oxygen saturation of the blood, which is a direct indicator of respiratory function. For a client with pneumonia, an improvement in oxygen saturation to 98% on room air is a strong sign that the lungs are effectively exchanging gases and that the pneumonia is resolving. This would be a clear indication that the amoxicillin is effective.

Choice C Reason

An increased neutrophil count is a sign of acute infection, but it does not directly measure the effectiveness of the antibiotic therapy. Neutrophil counts can remain elevated even as the infection is resolving, so they are not the best sole indicator of therapeutic effectiveness.

Choice D Reason

Adequate urine output is important for overall health and indicates good kidney function, but it is not a direct measure of the effectiveness of antibiotic therapy for pneumonia. Urine output does not reflect the respiratory status or the resolution of lung infection.

Correct Answer is D

Explanation

Choice A Reason:

Gas pains, while uncomfortable, are not typically a serious adverse effect of simvastatin and do not usually require immediate medical attention unless they are severe or persistent.

Choice B Reason:

Headaches are a common side effect of many medications, including simvastatin, and are not generally considered an emergency. However, if the headache is severe, persistent, or accompanied by other symptoms, it should be reported to a healthcare provider.

Choice C Reason:

Occasional constipation is another common side effect and is not usually a cause for immediate concern unless it becomes severe or chronic.

Choice D Reason:

Muscle weakness and pain, especially in the calves, can be a sign of a serious condition called rhabdomyolysis, which is a rare but serious adverse effect of statins like simvastatin. This condition involves the breakdown of muscle tissue and can lead to kidney damage. It should be reported to a healthcare provider immediately.

A. 1200 B. 1000 C. 0900 D. 1100

Correct Answer is C

Explanation

Choice A Reason
Monitoring for hypoglycemia at 1200 is not optimal because it is well past the peak action time of insulin aspart, which occurs approximately 45–90 minutes after administration. By noon, the insulin's effects are waning, and the risk of hypoglycemia is lower compared to the peak action period.

Choice B Reason
Monitoring at 1000 might still catch the tail end of the peak action time, but it is not the most likely time for hypoglycemia to occur. The nurse could miss the initial signs of hypoglycemia if monitoring starts two hours after administration.

Choice C Reason
0900 is the most appropriate time for the nurse to monitor for hypoglycemia. Insulin aspart has a rapid onset of action, peaking in about 45–90 minutes, and the effects last for 3–5 hours. Monitoring one hour after administration aligns with the start of the peak action time, when hypoglycemia is most likely to occur.

Choice D Reason
Monitoring at 1100 is less ideal because it is nearing the end of the peak action period. While there is still a risk for hypoglycemia, the highest risk would have been earlier, closer to the peak action time.
