PTCE Exam Dumps - Pharmacy Technician Certification (CPhT) Exam

Cefdinir is a third-generation cephalosporin antibiotic commonly used to treat bacterial infections, including otitis media (middle ear infection) in children. It is available in both capsule and suspension forms. However, cefdinir suspension is supplied in different concentrations, typically125 mg/5 mLand250 mg/5 mL.

The prescription provided specifies"Cefdinir suspension 5 mL PO q12h x 10 days", but it does not mention the concentration (strength) of the suspension. Without this crucial information, the pharmacy cannot accurately determine the total dosage the patient will receive. Different strengths would result in significantly different amounts of cefdinir per dose.

For example:

If the prescriber intended125 mg/5 mL, then the patient would receive125 mg per dose (250 mg daily).

If the prescriber intended250 mg/5 mL, then the patient would receive250 mg per dose (500 mg daily).

This discrepancy could lead tounderdosing or overdosing, making it essential for the pharmacy to contact the prescriber to confirm the correct concentration before dispensing.

A. Cefdinir is not available as a suspension.→ Incorrect. Cefdinir is available inoral suspensionform, typically in 125 mg/5 mL and 250 mg/5 mL concentrations.

C. Cefdinir suspension is not indicated for otitis media.→ Incorrect. Cefdinir is FDA-approved for the treatment of otitis media in pediatric patients.

D. Cefdinir suspension was prescribed for a child old enough to swallow capsules.→ Incorrect. While some 8-year-old children may be able to swallow capsules, many pediatric patients prefer liquid formulations, and prescribers often choose suspensions for better compliance.

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
