A nurse is participating in the care of a 4-year-old child as part of the interdisciplinary team. Which of the following observations should the nurse report to the physical therapist?

A) Time: The time of administration is an important factor to clarify. The prescription specifies erythromycin 500mg four times per day, but it does not specify the exact times the medication should be administered. The nurse should clarify the specific times to ensure the medication is given at proper intervals, especially considering the potential for drug interactions and the timing of meals, which may impact absorption.

B) Dosage: The dosage of 500mg is specified clearly in the prescription. There is no indication that the dosage is incorrect or needs clarification. Erythromycin 500mg four times per day is a standard dose for certain infections, so no issues are apparent with the dosage itself.

C) Route: The route of administration (oral, intravenous, etc.) is not specified in the question but is typically understood unless otherwise stated. However, in the context of erythromycin, the most common route is oral. Unless there’s uncertainty about the route, it does not need clarification.

D) Medication: The medication is clearly identified as erythromycin, which is a known antibiotic. There is no ambiguity in the medication prescribed, so there is no need for clarification in this regard. The focus should be on confirming the time of administration.

A) Decreased platelets: A decrease in platelet count (thrombocytopenia) is often associated with conditions such as bleeding disorders, bone marrow problems, or certain infections, but it is not a direct indicator of infection. While infections can cause a drop in platelets, this is not a specific or primary indicator of infection.

B) Decreased hemoglobin: A decrease in hemoglobin is typically indicative of anemia, which can result from a variety of causes, including nutritional deficiencies, chronic disease, or blood loss. While anemia can be associated with some infections, it is not a specific indicator of infection.

C) Increased erythrocyte sedimentation rate (ESR): An increased ESR is a nonspecific indicator of inflammation in the body and can be associated with infections, autoimmune diseases, and other inflammatory conditions. It is commonly elevated during infections, as the body responds to the inflammatory process. Therefore, an elevated ESR is a useful laboratory finding when suspecting an infection.

D) Increased iron level: Increased iron levels are typically associated with conditions such as hemochromatosis or iron overload, not with infections. During infections, iron levels can actually decrease due to the body's response to restrict iron availability to pathogens.
