Question 1 of 5
The nurse is preparing to administer digoxin (Lanoxin) 750 mcg PO daily. Available: See label below. How many pills should the nurse administer? Do not round your answer. Enter numeric answer only.
Correct Answer: A
Rationale: 750 mcg = 0.75 mg; if available is 0.25 mg/tablet, then 0.75 mg / 0.25 mg = 3 tablets.
Question 2 of 5
The nurse is preparing a client for discharge with a medical prescription for the HMG-CoA inhibitor, lovastatin [Mevacor]. Which statements from the client demonstrate a clear understanding of the teaching provided by the nurse?
Correct Answer: A
Rationale: Lovastatin works best at night (cholesterol synthesis peak) and grapefruit juice increases toxicity risk. It's taken with food, greens are fine, and alcohol/potassium aren't emphasized.
Question 3 of 5
The nurse is administering the first dose of hydralazine to an older adult. The nurse should place the client on which of the following precautions?
Correct Answer: B
Rationale: Hydralazine can cause orthostatic hypotension, increasing fall risk in older adults. Other precautions are unrelated.
Question 4 of 5
A client prescribed fluoxetine (Prozac) returns to the clinic one week after beginning therapy and states, "This drug is not working, I am still very sad." Which of the following would be the nurse's best response?
Correct Answer: D
Rationale: Fluoxetine, an SSRI, typically takes 4-6 weeks for full antidepressant effects. Adding drugs, switching early, or expecting results in 1-3 weeks is premature.
Question 5 of 5
The nurse is preparing to administer protamine sulfate for which of the following medication overdoses?
Correct Answer: D
Rationale: Protamine sulfate reverses heparin overdose by neutralizing its anticoagulant effects. It's not used for hydralazine, diphenhydramine, or warfarin.
