Question 1 of 5
A client with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate? Which response is accurate?
Correct Answer: D
Rationale: Open-angle glaucoma is a chronic condition requiring lifelong eye drop use to maintain normal intraocular pressure and prevent optic nerve damage. The drops are not for temporary pressure reduction, pain/swelling, or angle restoration, making long-term pressure control the accurate response.
Question 2 of 5
A client with heart failure (HF) develops hyperaldosteronism and spironolactone is prescribed. Which instruction should the nurse include in this client's plan of care? Which instruction should the nurse include in this client's plan of care?
Correct Answer: D
Rationale: Spironolactone, a potassium-sparing diuretic, can cause hyperkalemia. Limiting high-potassium foods like bananas and oranges prevents dangerous potassium elevations, which can lead to arrhythmias. Salt substitutes often contain potassium, and bruising or photosensitivity are not primary concerns.
Question 3 of 5
Prior to administering the evening dose of carbamazepine, the nurse notes that the client's morning carbamazepine level was 84 mcg/L (35.6 mmol/L). Which action should the nurse take? Which action should the nurse take?
Correct Answer: A
Rationale: A carbamazepine level of 84 mcg/L is significantly above the therapeutic range (4-12 mcg/mL), indicating toxicity. Notifying the healthcare provider is the most appropriate action to ensure timely intervention, such as withholding the dose or adjusting the regimen, to prevent serious effects like ataxia or seizures.
Question 4 of 5
A client with psychosis who is receiving an antipsychotic medication is continually rubbing the back of the neck. Which nursing intervention is best for the nurse to implement? Which nursing intervention is best for the nurse to implement?
Correct Answer: C
Rationale: Rubbing the back of the neck suggests extrapyramidal side effects (EPS), such as dystonia, from the antipsychotic medication. Benztropine, an anticholinergic, counteracts EPS by reducing muscle stiffness and spasms, providing rapid relief. Other interventions like heating pads or pillows may offer comfort but do not address the underlying EPS cause, and physical therapy is not an acute solution.
Question 5 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? Which instruction should the nurse provide to the client?
Correct Answer: D
Rationale: Erythromycin can reduce oral contraceptive efficacy by increasing metabolism. Using an additional contraceptive method, like condoms, prevents unintended pregnancy during and after the antibiotic course. Stopping the contraceptive or timing doses apart is not effective, and photosensitivity is not a concern with erythromycin.
