Question 1 of 5
A nurse is reinforcing teaching with the family of a client who has a new prescription for donepezil. Which of the following therapeutic effects should the nurse inform the family to expect?
Correct Answer: C
Rationale: Donepezil improves cognitive function in Alzheimer's disease by enhancing acetylcholine levels. It doesn't affect urinary output, pulmonary function, or seizure incidence.
Question 2 of 5
A nurse is collecting data from a client who has hypertension. The nurse should recognize that which of the following over-the-counter medications is contraindicated for this client?
Correct Answer: B
Rationale: Pseudoephedrine, a decongestant, can raise blood pressure, making it contraindicated in hypertension. Docusate, omeprazole, and guaifenesin don't significantly affect BP.
Question 3 of 5
A nurse is preparing to administer an enteric-corrected oral medication to a client who is having difficulty swallowing. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Placing an enteric-coated medication on the tongue allows easier swallowing without damaging the coating, which protects against stomach irritation. Chewing, dissolving, or buccal placement could compromise the coating.
Question 4 of 5
A nurse who is preparing to administer medications to a client is unfamiliar with a medication that the client takes at home. Which of the following resources should the nurse consult?
Correct Answer: D
Rationale: A nursing drug guide provides reliable, up-to-date information on medications, including indications and side effects, making it the best resource. Sales reps, team members, and family may lack comprehensive or current data.
Question 5 of 5
A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: 44 lb = 20 kg; 6 mg/kg/day = 120 mg/day; 120 mg / 3 doses = 40 mg/dose; 40 mg / 40 mg/mL = 1 mL/dose, rounded to 1 mL.
