rationales.
Domain 1: Medication Administration & Rights
1. A nurse is preparing to administer medications to a patient. Which of the following should the nurse
identify as the first step in the medication administration process?
A. Verify the medication dose B. Check the patient's identification using two
identifiers
C. Document the medication in the patient's chart D. Assess the patient for allergies
Answer: B
Rationale: The first step in medication administration is identifying the right patient using at least two unique
identifiers (e.g., name and date of birth). While allergy assessment, dose verification, and documentation are all
essential, patient identification must occur first to prevent administration to the wrong patient. This is the cornerstone
of the 'Six Rights' of medication administration.
2. A nurse is administering an intravenous medication and notices the IV site is red, swollen, and warm to
the touch. Which of the following actions should the nurse take first?
A. Apply a warm compress to the IV site B. Stop the infusion and discontinue the IV
access
C. Slow the infusion rate and reassess in 30 minutes D. Notify the pharmacy about a possible medication
reaction
Answer: B
Rationale: Redness, swelling, and warmth at an IV site are signs of phlebitis or infiltration. The first action is to stop
the infusion immediately and discontinue the IV access to prevent further tissue damage. Applying a warm compress,
slowing the rate, or notifying pharmacy delays necessary intervention and may worsen the patient's condition.
3. A nurse receives a verbal order from a provider for a new medication. Which of the following is the
correct action regarding this order?
A. Administer the medication and document the B. Read back the order to the provider for
verbal order later verification before documenting
1
, C. Ask the provider to send the order through the D. Refuse to accept verbal orders under any
electronic system within 24 hours circumstances
Answer: B
Rationale: When receiving a verbal medication order, the nurse must read back the complete order to the prescriber
for verification (read-back verification). This ensures accuracy and patient safety. The order should then be
documented promptly, and the provider should co-sign the order. Refusing all verbal orders is impractical in
emergencies, and administering before confirmation is unsafe.
4. A nurse is using the barcode medication administration (BCMA) system. The scanner indicates an error
when scanning the patient's wristband and medication. Which of the following is the most appropriate
action?
A. Override the system and administer the B. Investigate the cause of the error before
medication proceeding
C. Administer the medication manually without D. Skip the medication and administer it at the next
scanning scheduled time
Answer: B
Rationale: BCMA system errors are safety alerts that must be investigated before proceeding. Override or bypassing
the system removes critical safety checks designed to prevent medication errors. Skipping the dose could lead to under-
treatment. The nurse should verify the patient identity, medication order, and resolve any discrepancies before
administration.
5. During a medication reconciliation, a nurse discovers that a patient has been taking an over-the-counter
(OTC) herbal supplement that was not reported on admission. Which of the following is the priority nursing
action?
A. Advise the patient to discontinue the herbal B. Report the finding to the provider and
supplement immediately document it in the medication record
C. Note the supplement in the nursing notes only D. Contact the pharmacy to verify drug interactions
Answer: B
Rationale: The priority action is to report the OTC herbal supplement to the provider and document it in the official
medication record. Herbal supplements can have significant drug interactions (e.g., St. John's wort with SSRIs, ginkgo
with anticoagulants). The provider needs this information to make informed prescribing decisions. Notifying the
provider takes precedence over calling the pharmacy or advising discontinuation without assessment.
6. A nurse is administering a high-alert medication (e.g., heparin). Which of the following safety practices is
required for high-alert medications?
A. Administer the medication without independent B. Perform an independent double-check of the
verification in emergencies medication before administration
2
, C. Obtain a written consent form from the patient D. Administer the medication only when the
prior to administration prescriber is physically present
Answer: B
Rationale: High-alert medications (such as heparin, insulin, and opioids) require an independent double-check by a
second qualified nurse before administration. This ISMP-recommended practice significantly reduces the risk of errors
with medications that have the greatest potential for harm. Emergency situations do not negate the need for verification
when possible.
7. A nurse is preparing to administer a medication via the intramuscular (IM) route. The medication is known
to be irritating to subcutaneous tissue. Which injection site is most appropriate?
A. Deltoid muscle B. Vastus lateralis
C. Abdominal subcutaneous tissue D. Dorsogluteal muscle
Answer: B
Rationale: The vastus lateralis is the preferred IM injection site for irritating medications because it can accommodate
larger volumes (up to 3 mL in adults) and has a deep muscle mass that minimizes tissue irritation. The deltoid is limited
to small volumes (1 mL or less). The dorsogluteal site is no longer recommended due to risk of sciatic nerve injury.
Subcutaneous tissue should not be used for IM medications.
8. A nurse is documenting a medication that was administered 2 hours ago but forgot to document it at the
time. Which of the following is the correct documentation practice?
A. Document the current time as the administration B. Document the actual time of administration
time with a late-entry notation
C. Ask another nurse to document the medication D. Omit the documentation to avoid creating a
for you discrepancy
Answer: B
Rationale: Late entries must be documented with the actual time the medication was administered, along with a
notation indicating it is a late entry (e.g., 'Late entry: administered at 1400'). Falsifying the time or omitting
documentation compromises patient safety, legal integrity, and continuity of care. Accurate documentation is a legal
and professional responsibility.
Domain 2: Pharmacokinetics & Pharmacodynamics
9. A nurse is reviewing the concept of first-pass metabolism with a nursing student. Which of the following
best describes the first-pass effect?
A. The metabolism of a drug by the liver before B. The rapid distribution of a drug from the
it reaches systemic circulation bloodstream into tissues
