HESI Pharmacology Exam 2 Questions
Extract:
Question 1 of 5
An older adult with iron deficiency anemia is being discharged with a prescription for ferrous sulfate enteric-coated tablets. To promote best absorption of the medication, which information should the nurse include in the discharge instructions?
Correct Answer: C
Rationale: Ferrous sulfate is best absorbed on an empty stomach, waiting 2 hours after meals to avoid interference from food or minerals like calcium. Bedtime dosing risks GI upset, crushing enteric-coated tablets causes irritation, and multivitamins may contain interfering substances.
Question 2 of 5
The nurse is preparing a discharge teaching plan for a client who is taking ciprofloxacin hydrochloride tablets, which were prescribed because of a suspected anthrax exposure. Which instruction(s) should be included in the teaching plan? (Select all that apply.)
Correct Answer: C,D
Rationale: Ciprofloxacin is linked to tendonitis and rupture, requiring immediate reporting of tendon pain/swelling. Increased fluid intake prevents crystalluria, a side effect. Crushing tablets may alter efficacy, and NSAIDs increase seizure risk with ciprofloxacin, making these incorrect.
Question 3 of 5
The healthcare provider prescribes the antibiotic tetracycline HCl for an adult client that arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?
Correct Answer: B
Rationale: Tetracycline causes photosensitivity, increasing sunburn risk. Instructing the client to protect their skin from sunlight prevents skin damage. Orange juice, milk, or antacids reduce absorption, and serum levels are not routinely monitored for tetracycline.
Question 4 of 5
A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client’s history, the nurse determines that the client has been self-administering St. John’s Wort, an herbal preparation, on the advice of a friend. Which information is most significant about this finding?
Correct Answer: D
Rationale: St. John’s Wort induces liver enzymes, reducing cyclosporine levels, an immunosuppressant critical for preventing transplant rejection. This interaction directly contributes to graft rejection, making it the most significant finding. Sodium intake, corticosteroid needs, or depression treatment are less relevant to the acute issue.
Question 5 of 5
A female client who is a vegetarian has a new prescription for warfarin. The client states she eats leafy green vegetables every day. How should the nurse respond?
Correct Answer: B
Rationale: Warfarin’s anticoagulant effect is reduced by vitamin K, abundant in leafy greens. Informing the healthcare provider about the client’s consistent intake allows for dose adjustments to maintain therapeutic anticoagulation. Replacing vegetables is unnecessary, commending the diet ignores the interaction, and leafy greens may reduce warfarin’s efficacy, not enhance it.
