Introduction
This comprehensive ATI Pharmacology Study Guide is designed to provide nursing students
and healthcare professionals with a thorough review of essential pharmacological principles
and drug-specific knowledge required for success on the ATI Pharmacology Proctored Exam
and clinical practice. The assessment focuses on pharmacokinetics, pharmacodynamics,
drug classifications, therapeutic uses, adverse effects, nursing interventions, and patient
education. Students will be expected to apply pharmacological knowledge to clinical
scenarios, demonstrating safe medication administration, monitoring for adverse effects,
and patient teaching. This resource serves as a definitive study tool for exam preparation
,and self-assessment, ensuring readiness for the rigors of ATI testing and the NCLEX-RN
licensure examination.
SECTION ONE: QUESTIONS 1 – 100
1. A patient is prescribed digoxin for heart failure. Which assessment finding
indicates digoxin toxicity?
A. Hyperkalemia
B. Tachycardia
C. Yellow-green halos around lights
D. Hypotension
C. Yellow-green halos around lights
RATIONALE: Visual disturbances, including yellow-green halos around lights, are a
classic sign of digoxin toxicity. Other signs include nausea, vomiting, bradycardia, and
cardiac arrhythmias. Serum digoxin levels should be monitored.
2. A patient is prescribed warfarin. The nurse should monitor which laboratory
value to evaluate therapeutic effectiveness?
A. Activated partial thromboplastin time (aPTT)
B. International normalized ratio (INR)
C. Platelet count
D. Bleeding time
B. International normalized ratio (INR)
RATIONALE: Warfarin is monitored using the INR, with a therapeutic target typically
between 2.0 and 3.0 for most indications. The aPTT is used to monitor heparin therapy.
3. A patient with asthma is prescribed albuterol. The nurse understands that this
medication works by:
A. Blocking histamine release
B. Stimulating beta-2 adrenergic receptors to cause bronchodilation
C. Reducing inflammation in the airways
D. Increasing mucus production
B. Stimulating beta-2 adrenergic receptors to cause bronchodilation
RATIONALE: Albuterol is a short-acting beta-2 agonist that stimulates beta-2 receptors
in the bronchial smooth muscle, resulting in bronchodilation and relief of bronchospasm.
It is a rescue medication for acute asthma exacerbations.
,4. A patient is prescribed metformin for type 2 diabetes. Which instruction should
the nurse include in patient teaching?
A. "Take this medication on an empty stomach for best absorption."
B. "Monitor for signs of hypoglycemia, especially when taking alone."
C. "Take this medication with meals to reduce gastrointestinal side effects."
D. "This medication should be taken at bedtime."
C. "Take this medication with meals to reduce gastrointestinal side effects."
RATIONALE: Metformin commonly causes gastrointestinal side effects such as nausea
and diarrhea. Taking it with meals helps minimize these side effects. Metformin alone does
not typically cause hypoglycemia.
5. A patient is prescribed furosemide. Which electrolyte imbalance should the
nurse monitor for?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypercalcemia
B. Hypokalemia
RATIONALE: Furosemide is a loop diuretic that inhibits sodium and potassium
reabsorption in the ascending loop of Henle, leading to potassium loss and hypokalemia.
Serum potassium levels should be monitored.
6. A patient is receiving heparin therapy. Which adverse effect is most important
for the nurse to monitor?
A. Hyperkalemia
B. Bleeding
C. Heparin-induced thrombocytopenia (HIT)
D. All of the above
D. All of the above
RATIONALE: Heparin can cause bleeding, heparin-induced thrombocytopenia (HIT),
and hyperkalemia. The nurse should monitor for signs of bleeding, platelet counts, and
serum potassium levels.
7. A patient is prescribed lisinopril. Which side effect should the nurse monitor for
and teach the patient about?
A. Hyperkalemia
B. Hypokalemia
, C. Tachycardia
D. Hypoglycemia
A. Hyperkalemia
RATIONALE: Lisinopril is an ACE inhibitor that can cause hyperkalemia by decreasing
aldosterone secretion. Patients should be monitored for elevated potassium levels,
especially those with renal impairment.
8. A patient with a urinary tract infection is prescribed ciprofloxacin. Which
instruction should the nurse provide?
A. "Take this medication with dairy products to enhance absorption."
B. "Complete the full course of antibiotics even if symptoms improve."
C. "Take this medication only when symptoms are severe."
D. "Discontinue the medication if gastrointestinal upset occurs."
B. "Complete the full course of antibiotics even if symptoms improve."
RATIONALE: Antibiotics should be taken for the full prescribed course to prevent
antibiotic resistance and ensure complete eradication of the infection. Symptoms may
improve before the infection is fully cleared.
9. A patient is prescribed enoxaparin (Lovenox) for DVT prophylaxis. Which
instruction is most important for the nurse to provide?
A. "Massage the injection site after administration."
B. "Administer the medication in the same site each time."
C. "Rotate injection sites in the abdomen and do not expel the air bubble."
D. "Take aspirin daily to prevent bleeding."
C. "Rotate injection sites in the abdomen and do not expel the air bubble."
RATIONALE: Enoxaparin is administered subcutaneously in the abdomen, and
injection sites should be rotated to prevent bruising. The air bubble should not be expelled
from the prefilled syringe to ensure correct dosing.
10. A patient is prescribed an opioid analgesic for severe pain. Which side effect
should the nurse anticipate and manage?
A. Diarrhea
B. Constipation
C. Urinary incontinence
D. Hypotension
B. Constipation
RATIONALE: Opioid analgesics slow gastrointestinal motility, leading to constipation.
