When palpating the child's cervical lymph nodes, the nurse notes that they are tender, enlarged, and warm.
The best explanation for this is.

Choice A rationale:

Advising the caller to take his wife to the nearest emergency room for evaluation is the appropriate response. The new mom's symptoms, including confusion and auditory hallucinations (conversations with herself), are indicative of a serious mental health condition. These symptoms could be caused by postpartum psychosis, a rare but severe form of postpartum depression. Postpartum psychosis requires immediate medical attention and hospitalization for the safety of both the mother and the baby. It is essential to rule out any potential medical causes and provide appropriate psychiatric evaluation and treatment in an emergency setting.

Choice B rationale:

Bringing the wife to the office for medication is not appropriate in this situation. The symptoms described by the baby's father are severe and require urgent evaluation in an emergency room. Medication management should only be initiated after a comprehensive psychiatric evaluation, which can be conducted in an emergency room setting.

Choice C rationale:

Suggesting outpatient care is not appropriate in this case. The severity of the symptoms, including confusion and hallucinations, indicates the need for immediate evaluation in an emergency setting. Outpatient care is not sufficient for addressing acute psychiatric emergencies.

Choice D rationale:

Recommending behavioral therapy is not appropriate for a situation involving acute confusion and hallucinations. Behavioral therapy is a valuable treatment for various mental health conditions, but it is not the appropriate intervention for acute symptoms like those described in this scenario.

Choice A rationale:
The dosage prescribed for the child is 40 mg/kg/day, twice a day for 10 days. The child weighs 44 lbs, which is approximately 20 kg (1 lb = 0.45 kg). Therefore, the total daily dosage would be 40 mg/kg * 20 kg = 800 mg. This is split into two doses, so each dose would be 400 mg, not 400 mg per 5 ml as in the suspension.
Choice B rationale:
As explained above, the total daily dosage is 800 mg, split into two doses of 400 mg each. The suspension is written as 400 mg/5 ml, so one dose would be 400 mg.
Choice C rationale:
This choice is incorrect because it does not accurately calculate the dosage based on the child's weight and the prescribed dosage regimen.
Choice D rationale:
This choice is incorrect because it suggests a higher dose than what is prescribed. The correct dosage, based on the child's weight and prescription, is 800 mg per day, split into two doses of 400 mg each.
