An infant who weighs 22 lbs. receives a prescription for amoxicillin 20 mg/kg/day PO in divided doses every 8 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)
The Correct Answer is ["1.3"]
- Convert the infant's weight from pounds (lb) to kilograms (kg).
Given weight = 22 lb
Conversion factor = 1 kg = 2.2 lb
Weight (kg) = (Weight in lb / 2.2 lb/kg)
= (22 / 2.2)
= 10 kg.
- Calculate the total daily dose in milligrams (mg/day).
Prescribed dose = 20 mg/kg/day
Total Daily Dose (mg/day) = Weight (kg) x Dose (mg/kg/day)
= 10 kg x 20 mg/kg/day = 200 mg/day.
- Calculate the single dose in milligrams (mg/dose).
Frequency = every 8 hours (3 doses per day)
Single Dose (mg/dose) = (Total Daily Dose / Number of doses per day)
= (200 mg / 3)
= 66.67 mg.
- Calculate the volume in milliliters (mL) to administer per dose.
Available concentration = 250 mg per 5 mL
Volume (mL/dose) = (Single Dose (mg) / Available concentration (mg)) x Available volume (mL)
= (66.67 mg / 250 mg) x 5 mL
= 1.333... mL.
- Round the answer to the nearest tenth.
= 1.3 mL.

Correct Answer is A
Explanation
A. Complete blood count: Zidovudine can cause bone marrow suppression, leading to thrombocytopenia. Pinpoint red spots, or petechiae, are a sign of low platelet count. A CBC is the most relevant test to evaluate for cytopenias and should be reported promptly to the provider.
B. Skin biopsy: A biopsy would help diagnose dermatologic conditions such as rashes, lesions, or malignancies, but petechiae are usually vascular in nature and related to platelet abnormalities.
C. Allergy test: Allergy testing evaluates hypersensitivity to specific allergens but is not relevant here. Petechiae are not typical of allergic reactions; instead, they reflect impaired clotting or low platelets.
D. Electromyography: EMG measures electrical activity in muscles to assess for neuromuscular disorders. It has no connection to the client’s presentation of petechiae and is unrelated to zidovudine’s known adverse effects.
Correct Answer is D
Explanation
A. Recommend that he avoid fast food restaurants until he is familiar with his prescribed diet: Restricting social activities can lead to feelings of isolation and negatively affect adherence. It does not teach the adolescent practical skills for managing diabetes in real-life situations.
B. Encourage him to find activities to do with his friends that do not involve eating: While alternative activities are beneficial, avoiding meals with friends is not realistic for a teen. The goal is to promote self-management skills, not complete avoidance of social situations.
C. Advise him to take his own food with him when going to fast food restaurants with his friends: Bringing food may help in some situations, but it does not encourage the adolescent to make informed choices or learn how to navigate typical social eating environments.
D. Assist him in identifying popular fast foods that are within his meal plan for diabetes: Teaching the teen how to select appropriate options from common fast food menus empowers him to adhere to his diet while maintaining social interactions. This approach promotes self-management, independence, and realistic coping strategies.
