SECTION A: High-Alert Medications & The "5 Rights" of Medication
Administration (Q1–Q10)
Q1: A nursing instructor is reviewing the foundations of safe medication administration
with a clinical group. Which list contains ONLY the traditional "5 Rights" of medication
administration?
A. Right patient, right drug, right dose, right route, right time [CORRECT]
B. Right patient, right drug, right dose, right documentation, right evaluation
C. Right reason, right route, right response, right time, right assessment
D. Right drug, right dose, right to refuse, right education, right response
Correct Answer: A
Rationale: The traditional 5 Rights are patient, drug, dose, route, and time.
Documentation, reason, assessment, evaluation, response, and the right to refuse
belong to the expanded 10 Rights, not the original five.
Q2: A nurse enters the room of a patient to administer the 0900 medications. Which
action best fulfills the "right patient" requirement?
A. Asking the roommate, "Is this Mr. Alvarez's bed?"
B. Calling the patient by first name only, since the nurse has cared for him all week
C. Verifying two patient identifiers (name and date of birth) against the eMAR using the
barcode scanning system [CORRECT]
D. Confirming the room and bed number match the medication administration record
Correct Answer: C
Rationale: Two independent identifiers, verified against the MAR (ideally with barcode
scanning), are required to confirm patient identity. Room numbers change, names alone
are unreliable, and roommates cannot confirm identity safely.
Q3: A nurse educator is teaching a group about high-alert medications, defined as drugs
that bear a heightened risk of causing significant patient harm when used in error.
Which list correctly identifies high-alert medications?
,A. Insulin, heparin, opioids, neuromuscular blocking agents, concentrated electrolytes
[CORRECT]
B. Acetaminophen, docusate, multivitamins, oral antacids
C. Oral antibiotics, antihistamines, stool softeners, topical creams
D. Statins, proton pump inhibitors, chewable vitamins, saline nasal spray
Correct Answer: A
Rationale: ISMP's high-alert list includes insulin, anticoagulants such as heparin,
opioids, neuromuscular blockers, chemotherapy, and concentrated electrolytes because
errors with these are catastrophic. The other lists contain low-risk medications not
classified as high-alert.
Q4: A nurse is preparing insulin lispro from a U-100 vial for a patient with type 1
diabetes. Which safety action is required before administering this high-alert
medication?
A. Asking the nursing assistant whether the patient looks like he needs insulin
B. Programming the IV pump for a secondary infusion
C. Documenting the dose before drawing it up to save time
D. Completing an independent double check with a second nurse, verifying the insulin
type, concentration, dose, and syringe units before administration [CORRECT]
Correct Answer: D
Rationale: Insulin is high-alert; an independent double check of type, concentration
(U-100 vs. U-500), and drawn-up dose intercepts the most common insulin errors.
Appearance-based assessment, IV pump programming, and pre-documentation do not
verify the dose safely.
Q5: A provider orders heparin 5,000 units subcutaneous now for a patient with atrial
fibrillation. The pharmacy supplies a vial labeled "Heparin 10,000 units/mL." Which
action correctly fulfills the "right dose" check?
A. Draw up 1 mL in a tuberculin syringe
B. Calculate 5,000 units ÷ 10,000 units/mL = 0.5 mL and verify the calculated volume
and unit measurement against the order before administration [CORRECT]
C. Draw up the entire vial, since heparin is measured in units, not milliliters
D. Convert the units to milligrams and administer 5 mg
Correct Answer: B
Rationale: The dose calculation is 0.5 mL, and verifying both the calculation and the
unit-based measurement against the order fulfills the right dose. Drawing 1 mL delivers
a double dose, emptying the vial is unsafe, and heparin is not converted to milligrams
for subcutaneous dosing.
, Q6: The eMAR displays "metoprolol tartrate 25 mg PO daily," but the original provider
order reads "metoprolol tartrate 5 mg IV q6h × 3 doses." Which action should the nurse
take before administration?
A. Give the 25 mg oral dose, since oral is the safer route
B. Administer the IV dose quickly before the next vital sign check
C. Withhold the medication and clarify the route and dose discrepancy with the provider
before administering [CORRECT]
D. Split the difference and give 12.5 mg orally
Correct Answer: C
Rationale: A discrepancy between the eMAR and the original order must be clarified
before administration to satisfy the right drug, right dose, and right route. Guessing at
the safer route, rushing the IV dose, or altering the dose independently are unsafe and
out of nursing scope.
Q7: A nurse is reviewing facility policy regarding medication timing. Which statement
about the "right time" is most accurate?
A. Time-critical scheduled medications, such as insulin and antibiotics, must be
administered within 30 minutes before or after the scheduled time [CORRECT]
B. Any scheduled medication may be given at any point during the 12-hour shift
C. PRN medications require no timing considerations at all
D. All scheduled medications have a 4-hour administration window
Correct Answer: A
Rationale: CMS and medication-safety standards require time-critical drugs to be given
within 30 minutes of the scheduled time; non-time-critical daily medications generally
allow a 1–2 hour window per policy. Shift-wide flexibility and ignoring PRN timing create
unsafe practice.
Q8: A nursing student is asked to identify a right that is NOT part of the traditional 5
Rights of medication administration. Which response is correct?
A. Right patient
B. Right dose
C. Right documentation [CORRECT]
D. Right time
Correct Answer: C
Rationale: Right documentation is part of the expanded 10 Rights, not the traditional
five. Patient, dose, and time are three of the original five rights along with right drug and
right route.
