Question 1 of 5
A nurse is reinforcing teaching with a newly licensed nurse about age-related changes that affect medication administration for older adult clients. Which of the following information should the nurse include?
Correct Answer: A
Rationale: Aging reduces renal function, slowing drug excretion and increasing toxicity risk. Brain receptor sensitivity varies, gastric emptying slows, and hepatic metabolism decreases.
Question 2 of 5
A nurse is reinforcing teaching with a client who has a prescription for sildenafil to treat erectile dysfunction. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: B
Rationale: Fatty foods delay sildenafil absorption, reducing efficacy. It's taken as needed, not twice daily, doesn't prevent STDs, and constipation isn't a common side effect.
Question 3 of 5
A nurse is reinforcing teaching with a newly licensed nurse about age-related changes that affect medication administration for older adult clients. Which of the following information should the nurse include?
Correct Answer: A
Rationale: Aging reduces renal function, slowing drug excretion and increasing toxicity risk. Brain receptor sensitivity varies, gastric emptying slows, and hepatic metabolism decreases.
Question 4 of 5
A nurse is preparing to administer 0800 medications to a client. The medication administration record (MAR) states 'phenobarbital' and the medication the pharmacy supplied is pentobarbital. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Verifying the prescription clarifies the discrepancy between phenobarbital and pentobarbital, ensuring safety. Allergies, past intake, or MAR history don't directly resolve this.
Question 5 of 5
A nurse is preparing to administer acetaminophen 10 mg/kg PO every 6 hr to a toddler who weighs 26.4 lb. Available is acetaminophen 80 mg/0.8 mL liquid. How many mL should the nurse administer with each 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: 26.4 lb = 11.979 kg; 10 mg/kg × 11.979 = 119.79 mg; 119.79 mg ÷ (80 mg/0.8 mL) = 1.2 mL.
