A nurse is teaching a newly licensed nurse about transcribing prescriptions. Which of the following examples should the nurse include in the instructions?

A.

Losartan 50.0 mg, PO, QD

B.

Desmopressin .1 mL, intranasal, qd

C.

Metformin 500 mg, 1 tablet, PO, daily

D.

Zolpidem, 5 mg PO, HS

Answer and Explanation

The Correct Answer is C

A. Losartan 50.0 mg, PO, QD: The use of decimal points with trailing zeros (50.0 mg) is discouraged to avoid potential errors. It should be written as 50 mg.

B. Desmopressin .1 mL, intranasal, qd: The abbreviation "qd" (quaque die) is not recommended due to potential misinterpretation. It should be written as "daily."

C. Metformin 500 mg, 1 tablet, PO, daily: This prescription is clear and correctly formatted, including the dosage, route, and frequency without ambiguous abbreviations.

D. Zolpidem, 5 mg PO, HS: The abbreviation "HS" (at bedtime) is acceptable, but clarity and standardization are preferred, and this option is less specific compared to C.

Correct Answer is A

Explanation

A. Pull the auricle down and out: For a child under 3 years old, the ear canal is more horizontal, so the auricle should be pulled down and out to straighten the ear canal for proper instillation of ear drops.

B. Pull the auricle up and back: This technique is used for children older than 3 years old, as their ear canal becomes more vertical.

C. Pull the auricle up and out: This technique is incorrect for a 3-year-old child as it does not account for the horizontal position of the ear canal in younger children.

D. Pull the auricle down and back: This technique is not recommended for ear drops in young children and does not align with the anatomical considerations for their ear canal.

Correct Answer is ["56"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) Drop factor (gtt/mL)

First, calculate the total time in minutes:

  • 3 hours 60 minutes/hour = 180 minutes

Then, calculate the volume per minute:

  • 500 mL / 180 minutes = 2.78 mL/min

Finally, multiply the volume per minute by the drop factor:

  • 2.78 mL/min 20 gtt/mL = 55.6 gtt/min
  • Rounded off= 56gtt/min
