The nurse is evaluating the patient’s response to antibiotic therapy. Which data would indicate that the medication has been effective?

Decrease in inflammation at the site of infection.

Increase in circulating neutrophils.

Positive culture and sensitivity report.

Symptomatic fever.

Answer and Explanation

The Correct Answer is A

Choice A rationale

A decrease in inflammation at the site of infection is a key indicator that antibiotic therapy is effective. Inflammation is a response to infection, so if the inflammation is reducing, it suggests that the infection is being successfully treated.

Choice B rationale

An increase in circulating neutrophils could indicate an ongoing response to infection, rather than resolution. Neutrophils are a type of white blood cell that the body produces more of when there’s an infection. Therefore, an increase in neutrophils does not necessarily indicate that the antibiotic therapy has been effective.

Choice C rationale

A positive culture and sensitivity report indicates the presence of bacteria and identifies which antibiotics the bacteria are sensitive to. While this information is crucial for selecting the most effective antibiotic, it does not indicate whether the chosen antibiotic therapy has been effective.

Choice D rationale

A symptomatic fever could indicate an ongoing infection, rather than resolution. While fever can decrease as an infection is brought under control, the presence of a symptomatic fever does not necessarily indicate that the antibiotic therapy has been effective.

Correct Answer is D

Explanation

Step 1 is to understand the therapeutic range for aPTT when a patient is on heparin therapy. The therapeutic range for aPTT is 1.5 to 2.5 times the normal value. Given that the normal aPTT value is around 30-40 seconds, the therapeutic range would be approximately 45-100 seconds. Therefore, an aPTT value of 75 seconds falls within this therapeutic range, indicating that the heparin therapy is effective.
