INTRODUCTION
The ATI PN Pharmacology Proctored examination assesses the
knowledge, skills, and clinical judgment required to administer
medications safely and effectively as a practical nurse. The exam
,evaluates foundational pharmacologic principles, drug
classifications, adverse effects, nursing interventions, dosage
calculation, and patient education through multiple-choice and
Next Generation NCLEX (NGN)-style case scenarios. Candidates
must demonstrate competency in applying the nursing process to
medication administration, recognizing therapeutic and adverse
responses, and making evidence-based decisions to ensure patient
safety across the lifespan.
SECTION ONE: QUESTIONS 1–100
Question 1
A nurse is preparing to administer a medication. Which of the
following should the nurse use to identify the client? (Select all that
apply.)
A. Client's room number
B. Client's full name
C. Client's date of birth
D. Client's medical record number
E. Client's diagnosis
B, C, D
RATIONALE: The Joint Commission requires two client
identifiers before medication administration. Acceptable identifiers
include the client's full name, date of birth, and medical record
number. Room number and diagnosis are not reliable identifiers as
they can change or be assigned to different clients.
,Question 2
A nurse is reviewing a prescription that reads "metoprolol 25 mg PO
once daily." Which part of the prescription is missing?
A. Frequency
B. Route
C. Dose
D. Provider signature
D. Provider signature
RATIONALE: A complete prescription requires client name,
date, medication name, dose, route, frequency, and provider
signature. While "once daily" indicates frequency is present, the
provider's signature is missing, making the prescription incomplete.
Question 3
A nurse is administering a medication and considers its
pharmacokinetics. What does "pharmacokinetics" refer to?
A. How a drug produces its therapeutic effect at the cellular level
B. How the body absorbs, distributes, metabolizes, and excretes a
drug
C. The client's personal preference for a medication
D. The cost of the medication
B. How the body absorbs, distributes, metabolizes, and excretes
a drug
, RATIONALE: Pharmacokinetics describes the movement of a
drug through the body: absorption, distribution, metabolism, and
excretion (ADME). Pharmacodynamics, by contrast, describes the
drug's mechanism and effect on the body.
Question 4
Which organ is primarily responsible for the first-pass metabolism
of many oral medications?
A. Kidney
B. Liver
C. Lung
D. Spleen
B. Liver
RATIONALE: Orally administered drugs absorbed from the GI
tract travel via the portal circulation to the liver, where a significant
portion may be metabolized before reaching systemic circulation, a
process known as first-pass metabolism.
Question 5
A client has impaired renal function. Why is this significant when
administering a medication that is primarily renally excreted?
A. Renal function has no effect on medication dosing
B. Reduced renal function can cause drug accumulation and
toxicity, often requiring dose adjustment or increased monitoring
