1. What volume, in tsp, of a 20 mEq/15 mL solution would deliver a dose of 40 mEq?
A. 2
B. 6 Correct
C. 30
D. 40
Explanation
To determine the volume in teaspoons (tsp) that delivers 40 mEq from a 20 mEq/15 mL solution, calculate the concentration: 20 mEq / 15 mL = 1.333 mEq/mL. For a 40 mEq dose, the required volume is 40 mEq / 1.333 mEq/mL ≈ 30 mL. Since 1 tsp ≈ 5 mL, 30 mL / 5 mL/tsp = 6 tsp. Thus, the correct answer is 6 tsp.
2. According to USP Chapter 800, gowns worn during the preparation of hazardous nonsterile compounds must:
A. have seams or closures that could allow hazardous drugs to reach the skin
B. be selected based on the specific hazardous drugs being handled Correct
C. be made of reusable material to absorb hazardous drug residue
D. have short sleeves and open cuffs to minimize hazardous drug exposure
Explanation
USP Chapter 800 requires gowns to be selected based on the specific hazardous drugs to ensure proper protection against permeability and durability. Seams allowing drug exposure (A) and short sleeves with open cuffs (D) increase risk, while reusable materials (C) are unsuitable due to residue absorption, making B correct.
3. A pharmacy technician receives an order for azithromycin 200 mg/5 mL PO daily. What dosage form should be dispensed?
A. Tablet
B. Capsule
C. Suspension Correct
D. Suppository
Explanation
The order specifies azithromycin 200 mg/5 mL PO, indicating a liquid form with a concentration of 200 mg per 5 mL, which defines a suspension. Tablets (A) and capsules (B) are solids, and suppositories (D) are for rectal use, making Suspension the correct choice.
4. Following reconstitution, Varivax should be administered within a maximum of:
A. 30 minutes Correct
B. 48 hours
C. 7 days
D. 2 weeks
Explanation
Varivax (varicella vaccine) must be used within 30 minutes after reconstitution to maintain potency and safety, as per manufacturer guidelines and CDC recommendations, making A the correct answer. Longer timeframes (B, C, D) exceed safe storage limits.
5. A prescription calls for one capsule of a medication to be administered PO a.c. daily for 14 days. What directions should appear on the label?
A. Take one capsule by mouth daily for 14 days
B. Take one capsule by mouth after a meal once daily for 14 days
C. Take one capsule by mouth before a meal once daily for 14 days Correct
D. Take one capsule by mouth with a meal once daily for 14 days
Explanation
PO a.c.' means 'by mouth before meals.' The correct label direction should reflect this, specifying 'before a meal once daily for 14 days' (C). Options A, B, and D do not align with 'a.c.' (ante cibum), which indicates pre-meal administration.
