What does the medication abbreviation "PO" commonly stand for?
Per os (by mouth)
Per ocular
Per rectum
Per operating room
"PO" is an abbreviation of the Latin term "per os," meaning taken by mouth. It indicates the oral route of administration.
The abbreviation "q.d." on a prescription means:
Once a day
Every other day
Twice daily
As needed
"q.d." stands for the Latin "quaque die," which translates to once daily. It directs administering the medication once every day.
What is the correct meaning of the abbreviation "b.i.d."?
Twice daily
Three times a day
Once daily
Every six hours
"b.i.d." comes from the Latin "bis in die," meaning twice a day. It instructs dosing two times within a 24-hour period.
In prescription terminology, "IM" indicates which route of administration?
Intramuscular
Intravenous
Intraosseous
Inhalation
"IM" stands for intramuscular, indicating the medication should be injected into muscle tissue. Proper route identification prevents administration errors.
The abbreviation "SC" (or "SubQ") is used to denote which route?
Subcutaneous
Supraorbital
Sublingual
Subarachnoid
"SC" or "SubQ" refers to the subcutaneous route, meaning under the skin. Clear route abbreviations help ensure safe injections.
Which abbreviation is specifically listed on the Joint Commission's "Do Not Use" list?
U (unit)
PO
BID
QD
The abbreviation "U" for units is on the Joint Commission's Do Not Use list because it can be mistaken for a zero or the number four. Writing "units" in full avoids dosing errors.
Why is the abbreviation "MSO4" considered a risky shorthand?
It can be confused with morphine sulfate or magnesium sulfate
It is not recognized by pharmacies
It abbreviates a non-controlled substance
It conflicts with insulin dosing
"MSO4" can be misread as either morphine sulfate or magnesium sulfate, leading to serious medication errors. Using the full drug name ensures clarity.
Which practice helps prevent errors when writing decimal doses like 0.5 mg?
Always include a leading zero before the decimal point
Omit the zero and write .5 mg
Use trailing zero after the decimal
Write the dose in scientific notation
Including a leading zero (e.g., 0.5 mg) prevents misreading .5 mg as 5 mg. This practice reduces the risk of tenfold dosing errors.
Which abbreviation is ambiguous because it can mean both "discharge" and "discontinue"?
D/C
PRN
TID
QID
"D/C" can be interpreted as either discharge or discontinue, risking unintended therapy changes. Writing the full word avoids confusion.
What is a recommended best practice when indicating frequency instead of using "TID"?
Write "three times a day" in full
Use "tid" in lowercase
Combine it with "q8h"
Replace it with "3xd"
Writing "three times a day" fully instead of "TID" eliminates ambiguity for all staff. Spelling out frequencies enhances patient safety.
Which of the following is a priority strategy to reduce errors with look-alike/sound-alike drug names?
Use Tall Man lettering
Write both names in lowercase
Combine them into one abbreviation
Avoid using brand names
Tall Man lettering (e.g., vinBLAStine vs vinCRIStine) highlights differences in similar drug names and reduces selection errors. It is an ISMP-endorsed strategy.
A prescription reads ".25 mg digoxin." Why is this considered unsafe?
It lacks a leading zero before the decimal
It uses a decimal rather than a fraction
It should be written as 1/4 mg
It abbreviates the drug name
Writing ".25 mg" without a leading zero can be misread as "25 mg." A leading zero (0.25 mg) clearly indicates the intended dose.
Which of these is the clearest way to write a three-times-daily antibiotic order?
Cephalexin 500 mg by mouth every 8 hours
Cephalexin 500 mg TID
Cephalexin 500 mg po q8h prn
Cephalexin 500 mg per os three times a day
Writing "by mouth every 8 hours" fully conveys route and frequency without abbreviations. This format aligns with safety guidelines.
What is the correct interpretation of "q4-6h prn pain" on an order?
Every 4 to 6 hours as needed for pain
Four to six times daily for pain
Every 4 hours and 6 hours as needed
Between 4 AM and 6 PM for pain
"q4-6h prn pain" means the medication may be given every 4 to 6 hours if the patient experiences pain. It specifies a variable interval based on need.
Which feature of electronic prescribing can reduce unsafe abbreviation use?
Built-in alerts for prohibited abbreviations
Autofill using pharmacist initials
Free-text fields for all entries
Default frequency set to BID
Electronic prescribing alerts can flag "Do Not Use" abbreviations and prompt the prescriber to correct them, improving safety at the point of entry.
A clinician writes "Heparin 5000 U IV QHS." Which revision best follows safe prescribing guidelines?
Heparin 5,000 units IV every night at bedtime
Heparin 5000 U IV nightly
Heparin 5,000 units IV qhs
Heparin 5,000 IU IV every bedtime
This revision spells out "units," avoids the abbreviation QHS, and fully describes frequency. It aligns with Joint Commission standards.
Which organization publishes the official "Do Not Use" medication abbreviation list in the U.S.?
The Joint Commission
FDA
World Health Organization
American Pharmacists Association
The Joint Commission maintains a nationally recognized "Do Not Use" list of unsafe abbreviations to improve medication safety in accredited healthcare organizations.
To improve clarity, which change should be made to the order "ASA 81 mg PO daily"?
Write "Aspirin 81 mg by mouth daily" in full
Change ASA to Acetylsalicylic acid
Use "ASA 81 mg per os every day"
Include the brand name Bayer ASA
Replacing "ASA" with the full drug name "Aspirin" and spelling out the route and frequency eliminates ambiguity and meets best-practice guidelines.
A prescription reads "Levothyroxine .125 mg." What is the safest correction?
Levothyroxine 0.125 mg
Levothyroxine .125 mg every morning
Levothyroxine 1/8 mg
Levothyroxine 125 mcg
Adding a leading zero (0.125 mg) prevents misreading the dose as 125 mg, reducing the risk of a tenfold overdose.
Which of the following orders fully complies with best practices for clarity and safety?
Ciprofloxacin 500 mg orally every 12 hours for 7 days
Cipro 500 mg PO BID for seven days
Ciprofloxacin 500 mg po bid ×7d
Ciprofloxacin 500 mg by mouth twice a day
This order spells out the drug name, route, frequency, and duration without using unsafe abbreviations or symbols, adhering to guideline recommendations.
