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? Which instruction should the nurse provide to the client?
Correct Answer: C
Rationale: Erythromycin can reduce the effectiveness of oral contraceptives by increasing the metabolism of the hormones, leading to a higher risk of unintended pregnancy. Using an additional form of contraception, such as condoms, is recommended to prevent unintended pregnancy while taking both medications.
Question 2 of 5
To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client’s caregivers? Which instruction should the nurse provide to this client’s caregivers?
Correct Answer: A
Rationale: The fluticasone propionate and salmeterol discus is a maintenance medication designed for twice-daily use, approximately 12 hours apart. Using it more frequently increases the risk of side effects without additional benefit. It is not intended for acute asthma attacks, which require a short-acting bronchodilator like albuterol.
Question 3 of 5
The nurse is teaching a client who has been diagnosed with human immunodeficiency virus (HIV) about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse? Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: While antiretroviral therapy significantly reduces the risk of HIV transmission, it does not completely prevent it. The statement that it 'prevents' transmission overstates the effect, as preventive measures like condoms are still recommended despite an undetectable viral load.
Question 4 of 5
The nurse is providing discharge instructions to a client who has been prescribed gabapentin 300 mg by mouth (PO) three times a day for postherpetic neuralgia. Which symptom should the nurse tell the client to report to the healthcare provider? Which symptom should the nurse tell the client to report to the healthcare provider?
Correct Answer: B
Rationale: Gabapentin can cause fluid retention, leading to rapid weight gain, which may signal serious issues like heart or kidney problems. This symptom requires prompt reporting to the healthcare provider for further evaluation.
Question 5 of 5
A client receives a prescription for allopurinol. Which information provided by the client requires additional instruction by the nurse? Which information provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Doubling the dose of allopurinol if a dose is missed is incorrect and dangerous, as it can increase the risk of toxicity. The client should take the missed dose as soon as remembered, unless it’s nearly time for the next dose, then continue the regular schedule.
