Lisinopril is an ACE inhibitorused for hypertension and heart failure.

Standard dosing is once daily (q24h), not every 8 hours (q8h).

A frequency of q8h (three times daily) is unusual and could be a prescribing error.

(A) Directions for useCorrect -- 'q8h' is incorrect for lisinopril and needs clarification.

(B) Medication strengthIncorrect -- '20 mg' is a standard strength for lisinopril.

(C) Route of administrationIncorrect -- 'PO' (by mouth) is correct.

(D) Number of refillsIncorrect -- While 12 refills is uncommon for chronic medications, it is not the primary issue.

Analysis of the Prescription:Why the Directions Need Clarification:Analysis of Answer Choices:Reference for Pharmacy Technicians:

To determine the required volume of U-100 insulin to administer a20-unitdose ofNPH insulin, we use the concentration definition:

U-100 insulinmeans100 units per 1 ml

We need20 units

Using the formula:

Volume(ml)=Dose(units)Concentration(units/ml)\text{Volume (ml)} = \frac{\text{Dose (units)}}{\text{Concentration (units/ml)}}Volume(ml)=Concentration(units/ml)Dose(units)Volume=20units100units/ml=0.2ml\text{Volume} = \frac{20 \text{ units}}{100 \text{ units/ml}} = 0.2 \text{ ml}Volume=100units/ml20units=0.2ml

Thus, the correct answer is0.2 ml.

A . 0.02 ml Incorrect; this would correspond to only 2 units.

B . 1 ml Incorrect; this would correspond to 100 units, far exceeding the prescribed dose.

D . 2 ml Incorrect; this would correspond to 200 units, which is incorrect.

Analysis of the Answer Choices:Abbreviation

Meaning

ISMP Recommendation

U

Units

Do NOT use Can be mistaken for '0' or '4' (e.g., 10U could be misread as 100).Use'unit'instead.

AD

Right ear

Do NOT use Can be confused with 'OD' (right eye).Use'right ear'instead.

AU

Both ears

Do NOT use Can be confused with 'OU' (both eyes).Use'both ears'instead.

gtt

Drop

Accepted Common and not considered error-prone.

Since'gtt' for drop is not on ISMP's 'Do Not Use' list, it is the correct answer.

ISMP List of Error-Prone Abbreviations-- Confirms that 'U,' 'AD,' and 'AU' should not be used in prescriptions.

Joint Commission 'Do Not Use' List-- Prohibits 'U' and similar abbreviations to prevent dosing errors.

PTCB PTCE Exam Content Outline-- Covers error prevention strategies, including abbreviation safety.
