Chapter Reference: Chapter 1 — Section: Safety in Medication
Administration — Title: Safety in Medication Administration
Stem: A nurse reads the medication administration record (MAR) that
lists: methylPREDnisolone 40 mg PO daily at 0900. Which statement
about this order is correct?
A. “PO” is an inappropriate abbreviation and makes the order unsafe.
B. The medication order contains the required components and is
,written correctly.
C. The dose should be written as “40mg” (no space) for
standardization.
D. Tall-man lettering indicates that this medication is a controlled
substance.
Correct Answer: B
Rationales:
• Correct: B — The order lists drug name, dose (40 mg), route
(PO), frequency (daily at 0900) — all required components of a
complete medication order.
• A (incorrect): “PO” is an accepted standard abbreviation for oral
(by mouth); while some institutions prefer “by mouth,” “PO” is
commonly used and not uniformly prohibited. This distractor
reflects over-interpretation of abbreviation rules.
• C (incorrect): “40 mg” (with a space) is the recommended format
(space between number and unit). Writing “40mg” is a formatting
error but not the primary safety issue here.
• D (incorrect): Tall-man lettering is used to distinguish look-
alike/sound-alike drug names — not to mark controlled
substances. This distractor confuses purposes.
,Teaching Point: A complete order must include drug, dose, route, and
frequency.
2.
Chapter Reference: Chapter 1 — Section: Safety in Medication
Administration — Title: Medication Order Components
Stem: Which of the following is NOT one of the traditional “rights” of
medication administration commonly emphasized for safety?
A. Right patient
B. Right drug
C. Right frequency
D. Right documentation
Correct Answer: D
Rationales:
• Correct: D — While documentation is essential (and sometimes
called an additional “right”), the classic six rights are patient, drug,
dose, route, time/frequency, and documentation is often taught
separately or as the “seventh.” This item tests recognition of
classic vs. ancillary safety items.
, • A (incorrect): Right patient is one of the core rights.
• B (incorrect): Right drug is one of the core rights.
• C (incorrect): Right frequency/time is one of the core rights.
Teaching Point: Memorize the core six rights but always document
appropriately.

Chapter Reference: Chapter 1 — Section: Safety in Medication
Administration — Title: Look-Alike/Sound-Alike Prevention
Stem: Tall-man lettering (e.g., predniSONE vs predniSOLONE) is used
primarily to:
A. Indicate drugs requiring special disposal procedures.
B. Emphasize differences between look-alike/sound-alike drug names
to reduce selection errors.
C. Show controlled substance scheduling.
D. Signal that the medication must be refrigerated.
Correct Answer: B
