RN HESI Pharmacology Exam Questions
Question 1 of 5
A female client with mild depression reports to the nurse recently starting St. John's wort. Which information provided by the client requires further instruction?
Correct Answer: B
Rationale: St. John's wort reduces oral contraceptive efficacy by inducing liver enzymes, increasing pregnancy risk. Additional contraception is needed, requiring further instruction. Hard candy for dry mouth, insomnia, and sun sensitivity are accurate and do not need correction.
Question 2 of 5
A client who is taking an oral dose of a tetracycline reports gastrointestinal (GI) upset. Which snack should the nurse instruct the client to take with the tetracycline?
Correct Answer: B
Rationale: Tetracycline absorption is reduced by calcium in dairy products.
Toasted wheat bread and jelly, free of dairy or iron, minimizes GI upset and maintains efficacy. Cheese, yogurt, and milk contain calcium, impairing absorption.
Question 3 of 5
To prevent deep vein thromboses following knee replacement surgery, an adult male client is receiving daily subcutaneous enoxaparin. Which laboratory result requires immediate action by the nurse? Reference Range: Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)] Platelets [150,000 to 400,000/mm² (150 to 400 × 10^9/L)] Creatinine [0.5 to 1.1 mg/dL (44 to 97 μmol/L)] Blood Urea Nitrogen (BUN) [10 to 20 mg/dL (3.6 to 7.1 mmol/L)]
Correct Answer: A
Rationale: A platelet count of 100,000/mm³ indicates thrombocytopenia, a potential enoxaparin side effect, increasing bleeding risk. Immediate action (notifying provider, monitoring for bleeding) is needed. Hematocrit, BUN, and creatinine are within normal ranges and do not require urgent intervention.
Question 4 of 5
A client who experiences migraine headaches reports having fewer headaches since using the herbal remedy feverfew. Which information is most important for the nurse to include in a teaching plan for this client?
Correct Answer: B
Rationale: Feverfew’s antiplatelet effects increase bleeding risk when combined with aspirin or NSAIDs, critical for clients using these for migraines. Allergies, GI side effects, and anxiety are important but less urgent than bleeding risk.
Question 5 of 5
A client is receiving orlistat as part of a weight management program. Which ongoing assessment should be included in the plan of care to determine the effectiveness of the medication?
Correct Answer: B
Rationale: Orlistat blocks dietary fat absorption, aiding weight loss. Monitoring body mass index (BMI) assesses weight reduction and program success. Depression, calorie counts, and protein levels are unrelated to orlistat’s direct effects.
