ATI PHARMACOLOGY EXAM 2026–2027 | RN NURSING STUDY GUIDE & TEST PREP | SIDE
EFFECTS,, Exams of Pharmacology Comprehensive Assessment | 2026-2027 | 100 questions |
100% VERIFIED
Introduction
This comprehensive pharmacology assessment covers Antibiotics and Antimicrobials, Cardiovascular
Medications, Central Nervous System Drugs, Endocrine Medications, Gastrointestinal and Renal Drugs,
Respiratory and Immune Modulators, Oncology and Pain Management, and Medication Safety and Nursing
Implications. The questions emphasize adverse-effect recognition, safe administration, patient education,
monitoring, interaction awareness, and clinical pharmacology execution to support RN certification and
reliable nursing care.
1. A patient receiving vancomycin develops flushing and pruritus during infusion. Which action is appropriate?
A. Administer the next dose rapidly
B. Stop all antibiotics permanently
C. Slow the infusion and assess the patient
D. Give vitamin K
Rationale: Rapid infusion can cause histamine-mediated infusion reactions; slowing the rate and monitoring are
appropriate.
2. Which adverse effect is most important to monitor in a patient receiving gentamicin?
A. Severe constipation
B. Hyperthyroidism
C. Photosensitivity only
D. Nephrotoxicity and ototoxicity
Rationale: Aminoglycosides can injure renal tubules and cranial nerve VIII; renal function and hearing require
monitoring.
3. A patient taking tetracycline asks which instruction is correct.
A. Take it with iron to improve absorption
B. Avoid taking it with milk or antacids
C. Stop contraception permanently
D. Use it freely during pregnancy
Rationale: Calcium, magnesium, and iron bind tetracyclines; pregnancy and childhood use also require special caution.
4. Which teaching is essential for a patient taking metronidazole?
A. Take it with grapefruit juice
B. Expect harmless blue urine
C. Avoid alcohol during therapy and for the recommended period afterward
D. Use it with disulfiram routinely
Rationale: Metronidazole with alcohol can produce a severe disulfiram-like reaction; the other options are incorrect.
5. A patient develops watery diarrhea after clindamycin. Which complication is most concerning?
A. Acute appendicitis
B. Iron-deficiency anemia
C. Viral conjunctivitis
D. Clostridioides difficile colitis
Rationale: Clindamycin strongly predisposes to C. difficile overgrowth and toxin-mediated colitis.
6. Which medication is used to treat anaphylaxis from penicillin?
A. Intramuscular epinephrine
, B. Oral acetaminophen
C. Intravenous calcium only
D. Topical hydrocortisone only
Rationale: Epinephrine rapidly reverses airway edema, bronchospasm, and cardiovascular collapse; adjuncts cannot
replace it.
7. A patient taking rifampin should be taught that the drug may
A. Cause permanent white discoloration of teeth
B. Prevent all vaccine responses
C. Increase warfarin effect
D. Turn urine, tears, and other body fluids orange-red
Rationale: Rifampin commonly causes orange discoloration and induces hepatic enzymes, which can reduce effects of
several drugs.
8. Which finding suggests peripheral neuropathy from isoniazid?
A. Increased visual acuity
B. Severe bradycardia only
C. Numbness and tingling in the extremities
D. Excess salivation
Rationale: Isoniazid can cause pyridoxine-responsive peripheral neuropathy; pyridoxine supplementation may be
prescribed.
9. A patient taking fluoroquinolones reports sudden Achilles tendon pain. What should the nurse do?
A. Hold the medication and notify the prescriber
B. Encourage vigorous activity
C. Apply heat and continue without assessment
D. Double the next dose
Rationale: Fluoroquinolones can cause tendinopathy and tendon rupture; new tendon pain requires prompt
evaluation.
10. Which medication is preferred for uncomplicated oral candidiasis?
A. Oseltamivir
B. Acyclovir injection
C. Nystatin oral suspension
D. Praziquantel
Rationale: Nystatin acts locally against Candida; the other agents target viruses or helminths.
11. A patient taking acyclovir should be monitored for which problem?
A. Severe hypokalemia in every patient
B. Renal toxicity, especially with dehydration
C. Permanent hearing loss as the usual effect
D. Thyroid storm
Rationale: Acyclovir can crystallize in renal tubules; hydration and renal monitoring reduce risk.
12. Which antibiotic requires monitoring of hearing and vestibular function because of toxicity?
A. Amoxicillin
B. Azithromycin
C. Amikacin
D. Cephalexin
Rationale: Amikacin is an aminoglycoside with cochlear and vestibular toxicity risks.
13. A patient prescribed trimethoprim-sulfamethoxazole takes warfarin. Which concern is priority?
A. Complete reversal of anticoagulation
B. Immediate insulin resistance
C. Reduced risk of rash
