standards
Question 1
Which medication is classified as a high-alert medication by the ISMP due to its
narrow therapeutic index and risk of fatal errors?
A. Acetaminophen
B. Ciprofloxacin
C. Insulin
D. Omeprazole
Rationale: Insulin is a high-alert medication per ISMP because small dosing errors
can cause severe hypoglycemia, coma, or death. Independent double-checks,
barcode scanning, and clear labeling are required safety practices.
Question 2
Which abbreviation is considered error-prone and prohibited by The Joint
Commission?
A. mg
B. mL
C. U (for units)
D. mcg
Rationale: The abbreviation “U” for units is prohibited because it can be mistaken
for “0,” “4,” or “cc.” The word “units” must be written out in full to prevent dosing
errors (TJC National Patient Safety Goal 03.05.01).
Question 3
A patient is prescribed warfarin. Which laboratory value must be monitored regularly
to ensure safe and effective therapy?
A. Serum creatinine
B. Complete blood count
, C. International Normalized Ratio (INR)
D. Liver enzymes
Rationale: Warfarin therapy requires regular INR monitoring. The therapeutic
range is typically 2.0–3.0 for most indications. An INR >4.0 significantly increases
bleeding risk and requires immediate intervention per FDA Black Box Warning.
Question 4
Which pair of medications is an example of a look-alike/sound-alike (LASA) drug
error risk?
A. Metformin and glipizide
B. Lisinopril and metoprolol
C. Hydralazine and hydroxyzine
D. Amoxicillin and azithromycin
Rationale: Hydralazine (antihypertensive) and hydroxyzine (antihistamine) sound
similar and have been involved in serious errors. ISMP recommends using tall man
lettering (e.g., hydrALAZINE/hydroXYZINE) and separate storage to reduce LASA
risks.
Question 5
During medication reconciliation at admission, which information is most critical to
obtain?
A. Patient’s preferred pharmacy
B. Insurance coverage for medications
C. A complete and accurate list of all current medications, including
dose, frequency, and route
D. Patient’s last refill date
Rationale: TJC requires a best possible medication history (BPMH) obtained within
24 hours of admission. This includes all prescription, OTC, herbal, and vitamin
products with dose, frequency, and route to prevent omissions, duplications, and
interactions.
Question 6
Which medication carries an FDA Black Box Warning for tendon rupture?
A. Amoxicillin
B. Azithromycin
C. Levofloxacin
D. Doxycycline
Rationale: Fluoroquinolones (e.g., levofloxacin, ciprofloxacin) carry a Black Box
Warning for tendinitis and tendon rupture, especially in patients over 60, those on
corticosteroids, or with kidney disease. Use only when no alternative exists.
Question 7
Which action is essential when preparing a chemotherapy agent?
A. Wear standard gloves and gown
B. Prepare in a regular medication room
