Vaccines come in different strengths for adults and children, and mix-ups can lead to underdosing or overdosing.

Storing pediatric and adult vaccines separately within the refrigerator reduces the risk of errors.

Example:PediatricCOVID-19 vaccines (lower dose) and adult doses look similar but have different concentrations.

Why Other Options Are Incorrect:

A. Repackaging?❌Against CDC and USP <797> guidelines, which require vaccines to remain in their original packaging.

B. Ordering from different manufacturers?❌Not practical; most pharmacies use a single supplier for consistency.

D. Automated dispensing systems?❌Not always available for vaccines.

C. NDC not covered→ Would appear if the specific drug product (based on its National Drug Code) is not covered by insurance, but this scenario relates to duplication, not coverage.

D. Refill too soon→ This applies to refilling a medication before the allowed time frame, but the scenario describes a new prescription.

To determine the total number of10 mg prednisone tabletsrequired to fill the prescription, let's break it down by daily dosing:

First 2 days→ 20 mgtwice daily(b.i.d) =40 mg per day

Total for 2 days:40 mg × 2 =80 mg

Next 2 days→ 20 mgonce daily=20 mg per day

Total for 2 days:20 mg × 2 =40 mg

Next 2 days→ 10 mgonce daily=10 mg per day

Total for 2 days:10 mg × 2 =20 mg

Final 2 days→ 5 mgonce daily=5 mg per day

Total for 2 days:5 mg × 2 =10 mg

Days 1–4:(20 mg doses) → Each 20 mg dose requirestwo 10 mg tablets

Total for these 4 days:(20 mg × 4 days) = 80 mg

Tablets required:80 mg ÷ 10 mg =8 tablets

Days 5–6:(10 mg doses) → Each day requiresone 10 mg tablet

Total for these 2 days:10 mg × 2 =20 mg

Tablets required:20 mg ÷ 10 mg =2 tablets

Days 7–8:(5 mg doses) → Each day requireshalf of a 10 mg tablet

Total for these 2 days:5 mg × 2 =10 mg

Tablets required:1 full tablet (split into halves for two doses)

Step 1: Understanding the Prescription DirectionsStep 2: Determining the Number of 10 mg Tablets NeededFinal Calculation:8 tablets (Days 1-4) + 2 tablets (Days 5-6) + 1 tablet (Days 7-8) = 15 tablets
