Question 2

What does 'NKA' mean on a patient profile?

No Known Allergies

Answer

NKA stands for 'No Known Allergies,' indicating the patient has no documented drug, food, or environmental allergies on record.

Question 3

A prescription reads 'Metformin 500mg #60 Sig: 1 tab BID.' What is the days supply?

Accepted Answer

30 days

Answer

BID means twice daily (2 tablets/day); 60 tablets ÷ 2 = 30 days supply.

Question 4

Why did the ISMP recommend replacing the abbreviation 'QD' with 'once daily' in prescription writing?

Accepted Answer

'QD' could be misread as 'QID' (four times daily), causing dangerous dosing errors

Answer

The ISMP identified 'QD' as a dangerous abbreviation because it can be misread as 'QID' (four times daily) or 'OD' (right eye), so writing 'once daily' eliminates ambiguity.

Accepted Answer

Up to 5 refills within 6 months

Answer

Schedule V substances may be refilled up to 5 times within 6 months of the original prescription date, matching the rules for Schedule III and IV drugs.
