Question 1 of 5
A nurse is reviewing the medication list of a client who has a new prescription for tetracycline. The nurse should instruct the client to take which of the following medications 3 hr before or after taking the tetracycline?
Correct Answer: B
Rationale: Antacids can bind to tetracycline, reducing its absorption and effectiveness, so they should be taken 3 hours apart. Hydrochlorothiazide, lovastatin, and acetaminophen do not significantly interfere with tetracycline absorption.
Question 2 of 5
A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: 66 lb = 30 kg; 0.24 mg/kg/week = 7.2 mg/week; 7.2 mg / 6 doses = 1.2 mg/dose, rounded to 1.2 mg.
Question 3 of 5
A nurse is obtaining a medication history from a client who has systemic lupus erythematosus (SLE) and reports taking several herbal supplements daily. The nurse should identify that SLE is a contraindication for taking which of the following herbal supplements?
Correct Answer: C
Rationale: Echinacea boosts the immune system, which can worsen autoimmune conditions like SLE. Flaxseed, glucosamine, and ginger are not contraindicated and may even offer anti-inflammatory benefits.
Question 4 of 5
A nurse is caring for a client who is postoperative following arthroscopy and reports a pain level of 6 on a scale of 0 to 10 after receiving ketorolac 1 hr ago. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Oxycodone is appropriate for breakthrough pain (6/10) post-ketorolac. Ketorolac isn't dosed every 3 hours, rectal acetaminophen isn't first-line, and labeling as drug-seeking is premature.
Question 5 of 5
A nurse is caring for a client who has been taking epoetin alfa for 3 months. Which of the following laboratory tests should the nurse monitor to determine the effectiveness of the medication?
Correct Answer: D
Rationale: Epoetin alfa stimulates red blood cell production, so hemoglobin (Hgb) levels are monitored to assess its effectiveness. AST assesses liver function, troponin indicates heart damage, and T4 measures thyroid function, none of which relate to epoetin alfa's purpose.
