ATI RN CAPSTONE PHARMACOLOGY 2026/2027 PRACTICE EXAM
Questions Study Guide
DOCUMENT OVERVIEW
• Comprehensive Assessment Tool: This question practice exam simulates the ATI
RN Capstone Pharmacology assessment, designed to evaluate mastery of
Pharmacology 1 & 2 content with clinically relevant scenarios.
• Study Strategy: Work through all 200 questions, review rationales thoroughly,
identify weak areas, and focus additional study on topics with lower performance
before taking the actual ATI exam.
SECTION 1: CARDIOVASCULAR PHARMACOLOGY
QUESTION 1
A nurse is reviewing a patient's medication list and notices the patient is taking a
beta-blocker for hypertension. Which of the following is the primary mechanism of
action for beta-blockers?
A) Inhibiting angiotensin II formation
B) Blocking calcium channels in vascular smooth muscle
C) Blocking beta-adrenergic receptors in the heart and blood vessels
D) Directly relaxing vascular smooth muscle
,E) Increasing sodium and water excretion
CORRECT ANSWER: C) Blocking beta-adrenergic receptors in the heart and
blood vessels
RATIONALE: Beta-blockers work by blocking beta-adrenergic receptors, which
decreases heart rate, myocardial contractility, and blood pressure. This mechanism
reduces the heart's workload and oxygen demand. Options A, B, D, and E represent
mechanisms of action for ACE inhibitors, calcium channel blockers, direct
vasodilators, and diuretics respectively—not beta-blockers.
QUESTION 2
A 58-year-old client with heart failure is prescribed an ACE inhibitor. What is the
primary therapeutic effect of ACE inhibitors in treating heart failure?
A) Increasing myocardial contractility
B) Decreasing preload and afterload by inhibiting angiotensin II formation
C) Increasing heart rate to improve cardiac output
D) Promoting fluid retention to maintain cardiac filling pressures
E) Blocking calcium influx into cardiac cells
CORRECT ANSWER: B) Decreasing preload and afterload by inhibiting
angiotensin II formation
RATIONALE: ACE inhibitors reduce preload and afterload by preventing the
conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. This reduces
the workload on the failing heart. The drug does not increase contractility (A),
increase heart rate (C), or promote fluid retention (D). While they affect vascular
tone, the mechanism is not calcium channel blockade (E).
,QUESTION 3
A nurse is monitoring a patient taking digoxin for atrial fibrillation. Which
therapeutic serum level range should the nurse maintain for digoxin?
A) 0.5-1.0 ng/mL
B) 2.5-5.0 ng/mL
C) 0.8-2.0 ng/mL
D) 3.0-6.0 ng/mL
E) 5.0-10.0 ng/mL
CORRECT ANSWER: C) 0.8-2.0 ng/mL
RATIONALE: The therapeutic serum level for digoxin is 0.8-2.0 ng/mL. Levels below
this range are ineffective, while levels above 2.0 ng/mL increase the risk of digoxin
toxicity, including arrhythmias, nausea, and visual disturbances. This narrow
therapeutic window requires regular monitoring.
QUESTION 4
A patient is started on a statin for hyperlipidemia. Which statement best describes
the mechanism of action of statins?
A) They increase the excretion of cholesterol through the bile
B) They inhibit HMG-CoA reductase, the rate-limiting enzyme in cholesterol
synthesis
C) They bind to dietary cholesterol in the gastrointestinal tract
D) They increase HDL cholesterol while decreasing LDL cholesterol
E) They block the absorption of triglycerides in the small intestine
CORRECT ANSWER: B) They inhibit HMG-CoA reductase, the rate-limiting
enzyme in cholesterol synthesis
, RATIONALE: Statins work by inhibiting HMG-CoA reductase, which catalyzes an
early step in cholesterol synthesis. This reduces hepatic cholesterol production,
causing cells to upregulate LDL receptors and remove more cholesterol from the
bloodstream. Option A describes bile acid sequestrants, C describes ezetimibe, and
E describes fibrates.
QUESTION 5
A nurse is educating a patient starting on an antihypertensive medication. The
patient asks why they need to take the medication even though they feel fine. What
is the most appropriate nursing response?
A) "You need to take it because your blood pressure is very high right now"
B) "Hypertension is often called a silent killer because you may have no symptoms,
but it can damage your organs over time"
C) "The medication will help you feel better and have more energy"
D) "Without this medication, you will have a stroke within a year"
E) "This medication will prevent all cardiovascular diseases"
CORRECT ANSWER: B) "Hypertension is often called a silent killer because you
may have no symptoms, but it can damage your organs over time"
RATIONALE: Hypertension is frequently asymptomatic, which is why it's called a
"silent killer." Education should emphasize that even without symptoms, persistent
high blood pressure damages the kidneys, heart, and blood vessels. Option A
assumes the patient has high readings currently, C promises symptom
improvement, D is fear-based and inaccurate, and E overstates drug efficacy.
