A prescription for a 5-year-old reads amoxicillin of ¼ a 500 mg tablet every 8 hours for 5 days. The pharmacy stocks amoxicillin in both a chewable 125 mg tablet and suspension. What should you do?
Dispense either a chewable tablet or liquid form of the medication.
Dispense the medication as written, breaking the tablets prior to dispensing them
Dispense the medication as written, instructing the parent to break the tablets into four pieces.
Consult with the pharmacist or authorized prescriber before changing the form of the medication
The Correct Answer is D
A. Dispense either a chewable tablet or liquid form of the medication: Even though alternatives exist, dispensing a different form without prescriber authorization may lead to dosing inconsistencies or legal concerns. Proper protocol requires confirmation.
B. Dispense the medication as written, breaking the tablets prior to dispensing them: Splitting a 500 mg tablet into quarters may not ensure accurate dosing, especially in a child. Tablets may not split evenly, and not all are scored or safe to divide.
C. Dispense the medication as written, instructing the parent to break the tablets into four pieces: This puts responsibility on the caregiver to split tablets into exact quarters, which can lead to dosing errors. It is unsafe and inappropriate for pediatric medication.
D. Consult with the pharmacist or authorized prescriber before changing the form of the medication: The safest and most appropriate action is to confirm any modifications to a prescription. For pediatric patients, ensuring accurate dosage form and administration requires provider consultation.

Correct Answer is C
Explanation
A. ASA gr v q4h prn pain: This order uses outdated terminology ("gr v" for grain 5) and lacks a specified route. Current standards require metric units and a clearly defined route to reduce errors.
B. ASA 325 mg po prn fever: While the dosage, route, and indication are present, the frequency is missing. "prn" must be accompanied by a frequency (e.g., q4h) to be a complete and actionable order.
C. Aspirin 325 mg po q4h prn headache: This order includes the drug name, dosage, route, frequency, and specific indication. It uses current, safe prescribing standards and is a complete and appropriately written PRN medication order.
D. Aspirin po q4h prn toothache: This order is missing the dosage, which is critical for safe medication administration. Without the amount to administer, the order is incomplete and not acceptable for execution.
Correct Answer is ["0.67"]
Explanation
Desired dose = 8 mg.
Concentration of the available medication = 6 mg in 0.5 mL.
Concentration = 6 mg / 0.5 mL
= 12 mg/mL.
- Calculate the volume in milliliters (mL) to administer.
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
= 8 mg / 12 mg/mL
= 0.6666... mL.
- Rounding to the nearest hundredth
= 0.67 mL.
