,Chapter 1: Safety in Medication Administration – Test Bank
1. A nurse is preparing to administer a new medication to a patient. Which of the following is
the most important first step to ensure safe medication
administration?
A. Verify the patient’s identity
B. Shake the medication vigorously
C. Document the medication after administration
D. Ask the patient if they want the medication
CORRECT ANS: A
Rationale: Verifying the patient’s identity using two identifiers (e.g., name and date of birth) is
the most critical first step to prevent medication errors.
2. The “Five Rights” of medication administration include all of the following
EXCEPT:
A. Right patient
B. Right dose
C. Right documentation
D. Right allergy
CORRECT ANS: D
Rationale: The five rights are right patient, right drug, right dose, right route, and right time.
Checking allergies is essential but is not one of the “five rights.”
3. A patient refuses a prescribed medication. What should the nurse do first?
A. Explain the consequences of not taking the medication
B. Document the refusal and notify the provider
,C. Force the patient to take the medication
D. Leave the medication at the bedside
CORRECT ANS: B
Rationale: Patient autonomy must be respected. The nurse should document the refusal, notify
the provider, and provide education as appropriate.
4. A new nurse administers a medication at the wrong time. Which safety principle is most
directly involved?
A. Right patient
B. Right route
C. Right time
D. Right documentation
CORRECT ANS: C
Rationale: Administering medications at the prescribed time is critical to ensure therapeutic
effectiveness and prevent adverse effects.
5. Which of the following is considered a high-alert medication?
A. Acetaminophen
B. Insulin
C. Amoxicillin
D. Ibuprofen
CORRECT ANS: B
Rationale: High-alert medications, like insulin, have a higher risk of causing serious harm if used
incorrectly. Nurses must take extra precautions when administering these medications.
6. A nurse is checking a patient’s MAR and notices an unclear order. The best action is:
A. Administer the medication anyway
, B. Clarify the order with the prescriber
C. Ask a colleague to interpret the order
D. Wait until the next shift to clarify
CORRECT ANS: B
Rationale: Administering medications without a clear order is unsafe. The nurse must clarify
unclear orders with the prescriber before administration.
7. Which of the following actions is an example of preventing medication errors?
A. Ignoring a double-check policy to save time
B. Using a bar-code scanning system for verification
C. Relying solely on memory for dose calculations
D. Administering leftover medications from a previous patient
CORRECT ANS: B
Rationale: Using technology like bar-code scanning helps prevent errors and ensures the right
medication is given to the right patient.
8. A patient receives a medication intended for another patient. This is an example of:
A. Adverse drug reaction
B. Medication error
C. Side effect
D. Therapeutic effect
CORRECT ANS: B
Rationale: Administering medication to the wrong patient constitutes a medication error and
must be reported and addressed immediately.
9. Which organization sets guidelines to improve patient safety in medication administration?
A. FDA
B. Institute for Safe Medication Practices (ISMP)
