Exam Structure
The ATI Comprehensive Pharmacology Proctored Exam for the 2026/2027 academic cycle is a
110-question, multiple-choice question (MCQ) examination.
Introduction
This ATI Comprehensive Pharmacology Proctored Exam guide for the 2026/2027 cycle prepares nursing
students for the high-stakes proctored assessment of pharmacologic knowledge essential for safe nursing
practice. The content integrates principles of drug therapy across all major body systems and patient
populations, emphasizing medication safety, accurate calculation, therapeutic effects, side effect
management, and patient education.
Answer Format
All correct answers and pharmacologic principles must be presented in bold and green, followed by
detailed rationales that explain drug mechanisms of action, calculate accurate dosages, identify major
adverse effects and contraindications, justify nursing interventions for monitoring and administration,
and apply age-specific considerations to medication therapy.
Questions (110 Total)
1. A nurse is preparing to administer digoxin 0.25 mg IV. The vial contains 0.5 mg/mL. How many mL
should the nurse administer?
A. 0.25 mL
B. 0.5 mL
C. 1.0 mL
D. 2.0 mL
Rationale: Desired dose = 0.25 mg. Concentration = 0.5 mg/mL. Volume = 0.25 ÷ 0.5 = 0.5 mL.
Always verify calculations using dimensional analysis. Digoxin is a high-alert medication; double-check
with another nurse when required.
,2. A client taking warfarin has an INR of 5.0. What is the priority action?
A. Administer vitamin K orally
B. Hold warfarin and notify the provider
C. Increase warfarin dose
D. Encourage green leafy vegetables
Rationale: INR >4.5 indicates high bleeding risk. Hold warfarin and notify provider. Vitamin K may
be given if INR >10 or active bleeding. Do not increase dose or encourage vitamin K-rich foods without
orders.
3. Which medication requires dose adjustment in a client with chronic kidney disease (CKD)?
A. Loratadine
B. Metformin
C. Levothyroxine
D. Atorvastatin
Rationale: Metformin is contraindicated if eGFR <30 and requires dose reduction or discontinuation
at eGFR 30–45 due to lactic acidosis risk. Loratadine, levothyroxine, and atorvastatin do not require
routine renal adjustment.
4. A client with heart failure is prescribed lisinopril. What is the primary purpose of this medication?
A. Increase heart rate
B. Reduce afterload and prevent ventricular remodeling
C. Promote sodium retention
D. Stimulate cardiac contractility
Rationale: ACE inhibitors like lisinopril reduce afterload by inhibiting angiotensin II production,
decreasing systemic vascular resistance. They also block aldosterone, reducing sodium/water retention,
and slow adverse ventricular remodeling. Per ACC/AHA guidelines, ACE inhibitors are first-line in
HFrEF unless contraindicated.
5. A client receiving chemotherapy reports mouth sores and difficulty swallowing. What is the best
nursing intervention?
,A. Offer citrus juices
B. Provide oral care with saline or baking soda rinses and soft foods
C. Administer aspirin for pain
D. Encourage alcohol-based mouthwash
Rationale: Chemotherapy-induced mucositis requires gentle oral hygiene. Saline or baking soda rinses
soothe and clean. Avoid acidic (citrus), spicy, or alcohol-based products—they irritate. Aspirin increases
bleeding risk. Soft, bland foods reduce trauma. Oral cryotherapy may be used with certain agents (e.g.,
5-FU).
6. Which medication is contraindicated in a client with a history of sulfa allergy?
A. Amoxicillin
B. Sulfamethoxazole-trimethoprim (Bactrim)
C. Ciprofloxacin
D. Azithromycin
Rationale: Bactrim contains a sulfonamide antibiotic and is contraindicated in sulfa-allergic patients
due to risk of Stevens-Johnson syndrome, rash, or anaphylaxis. Penicillins, fluoroquinolones, and
macrolides are unrelated to sulfa drugs.
7. A client with type 2 diabetes is prescribed metformin. What is the most important teaching point?
A. “Take it on an empty stomach.”
B. “Report muscle pain or dark urine immediately.”
C. “Avoid all carbohydrates.”
D. “Skip doses if you feel dizzy.”
Rationale: Metformin can rarely cause lactic acidosis, signaled by muscle pain, weakness, or dark
urine. It should be held before procedures with contrast dye. It does not cause hypoglycemia and is
taken with meals to reduce GI upset.
8. A client taking haloperidol develops muscle rigidity, fever, and altered mental status. What condition is
suspected?
A. Akathisia
, B. Neuroleptic malignant syndrome (NMS)
C. Tardive dyskinesia
D. Serotonin syndrome
Rationale: NMS is a life-threatening reaction to antipsychotics, characterized by “Fever,
Encephalopathy, Rigidity, Autonomic instability” (FERA). Discontinue the drug, provide supportive
care, and consider dantrolene or bromocriptine. Serotonin syndrome involves hyperreflexia and occurs
with serotonergic drugs.
9. A pregnant client at 28 weeks gestation has a urinary tract infection. Which antibiotic is safe to
administer?
A. Doxycycline
B. Cephalexin
C. Levofloxacin
D. Trimethoprim-sulfamethoxazole
Rationale: Cephalosporins (e.g., cephalexin) are pregnancy Category B and safe in all trimesters.
Doxycycline (tetracycline) causes tooth discoloration; fluoroquinolones (levofloxacin) affect cartilage;
TMP-SMX is avoided in the first and third trimesters due to folate antagonism and kernicterus risk.
10. A client with asthma is prescribed albuterol via metered-dose inhaler (MDI). What instruction should
the nurse provide?
A. “Use daily even if asymptomatic.”
B. “Shake the canister before use and wait 1 minute between puffs.”
C. “Rinse your mouth before inhaling.”
D. “Exhale into the inhaler before pressing.”
Rationale: Albuterol MDIs must be shaken to mix the suspension. Wait 1 minute between puffs for
optimal absorption. Rinse mouth after corticosteroid inhalers (not albuterol) to prevent thrush. Exhale
away from the inhaler, then inhale slowly while actuating.
11. A client with COPD is prescribed ipratropium. This medication works by:
A. Stimulating beta-2 receptors
B. Blocking parasympathetic (muscarinic) receptors
