ATI Pharmacology: Medication Administration & Error
Prevention Pack 2026/2027 UPDATED ACTUAL Exam
Questions and CORRECT Answers
1. A nurse is preparing to administer a medication to a client. Which of the
following identifiers is acceptable for verifying the client’s identity?
A. The client’s room number
B. The client’s bed number
C. The client’s physical description
D. The client’s full name and date of birth
E.
Answer: D
Rationale: Safe medication administration requires at least two unique identifiers, such as
name and date of birth. Facility-specific identifiers like a medical record number are also
acceptable, but room or bed numbers are never used.
2. A nurse discovers a medication error. Which of the following actions should
the nurse take first?
A. Notify the provider.
B. Complete an incident report.
C. Inform the nurse manager.
D. Assess the client’s condition.
Answer: D
Rationale: The first priority after a medication error is always the safety of the client. The
nurse must assess the client for any adverse effects before notifying others or documenting.
,3. A nurse is providing teaching to a client about a new sublingual medication.
Which instruction should the nurse include?
A. Swallow the tablet with a full glass of water.
B. Chew the tablet thoroughly before swallowing.
C. Crush the tablet and mix it with applesauce.
D. Allow the tablet to dissolve completely under the tongue.
Answer: D
Rationale: Sublingual medications must dissolve under the tongue to be absorbed through
the mucous membranes into the bloodstream. Swallowing or chewing them bypasses this
route and may render the medication ineffective due to the first-pass effect.
4. A nurse is preparing to administer an intramuscular (IM) injection. Which site
is the preferred location for adults due to being away from major nerves and
blood vessels?
A. Ventrogluteal
B. Dorsogluteal
C. Deltoid
D. Vastus lateralis
Answer: A
Rationale: The ventrogluteal site is the preferred and safest site for IM injections in adults
because it is located away from major nerves and blood vessels and has a thick muscle
mass.
5. What is the ‘first-pass effect’ in pharmacology?
A. The rapid excretion of a drug by the kidneys.
B. The initial metabolism of an oral drug in the liver before it reaches systemic circulation.
C. The time it takes for a drug to reach its peak concentration.
D. The binding of a drug to plasma proteins in the blood.
Answer: B
, Rationale: The first-pass effect occurs when oral medications are absorbed from the GI
tract into the portal circulation and metabolized by the liver, significantly reducing the
amount of active drug that reaches the systemic circulation.
6. A nurse is preparing to administer a liquid medication to an infant. Which of
the following methods should the nurse use?
A. Use a needleless syringe to place the medication in the side of the mouth.
B. Mix the medication with a full bottle of formula.
C. Administer the medication using a teaspoon from the kitchen.
D. Place the medication in the back of the infant’s throat to prevent spitting.
Answer: A
Rationale: Using a syringe to place medication in the side of the mouth (buccal area)
prevents aspiration and ensures the infant receives the full dose. Mixing with formula is
discouraged as the infant may not finish the bottle.
7. A nurse is administering ear drops to a 2-year-old child. In which direction
should the nurse pull the auricle?
A. Up and back
B. Down and back
C. Straight back
D. Down and forward
Answer: B
Rationale: For children under the age of 3, the ear canal is straightened by pulling the
auricle down and back. For adults, it is pulled up and back.
