Extract:
Question 1 of 5
A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?
Correct Answer: A
Rationale: Erythromycin may reduce the effectiveness of oral contraceptives. Using an additional form of contraception ensures protection against unintended pregnancy during antibiotic treatment.
Question 2 of 5
A client with chemotherapy-induced nausea receives a prescription for metoclopramide. Which adverse effect is most important for the nurse to report?
Correct Answer: B
Rationale: Metoclopramide can cause extrapyramidal symptoms like involuntary movements (e.g., tardive dyskinesia), which are serious and may require medication adjustment or discontinuation. This adverse effect is more critical to report than diarrhea, irritability, or nausea.
Question 3 of 5
A client with allergic rhinitis is taking the over-the-counter antihistamine diphenhydramine HCL. Which instruction is most important for the nurse to provide this client?
Correct Answer: B
Rationale: Diphenhydramine causes significant drowsiness, posing a safety risk when driving. This instruction is critical to ensure the client’s safety and prevent accidents.
Question 4 of 5
The nurse is caring for an adult client who is taking digoxin. Which laboratory value should be reported to the healthcare provider immediately?
Correct Answer: B
Rationale: A potassium level of 3.2 mEq/L indicates hypokalemia, which increases the risk of digoxin toxicity and cardiac arrhythmias. This value requires immediate reporting to prevent potentially life-threatening complications.
Question 5 of 5
The nurse is reviewing the client's laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?
Correct Answer: A
Rationale: Atorvastatin lowers LDL cholesterol, a key risk factor for coronary artery disease. A decrease in LDL levels indicates the medication is effectively reducing cardiovascular risk, making it the primary indicator of therapeutic success.
