A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?
Stop the oral contraceptive immediately.
Take the medications at least 12 hours apart.
Use an additional form of contraception.
Avoid prolonged exposure to direct sunlight.
The Correct Answer is C
Choice A reason: Stopping the oral contraceptive immediately is not necessary and may increase the risk of unintended pregnancy. Erythromycin can reduce the effectiveness of oral contraceptives by interfering with their metabolism, but it does not make them completely ineffective.
Choice B reason: Taking the medications at least 12 hours apart is not sufficient to prevent the interaction between erythromycin and oral contraceptives. The interaction can occur regardless of the timing of the doses.
Choice C reason: Using an additional form of contraception is the best instruction for the client who is taking an oral contraceptive and erythromycin. This can prevent pregnancy in case the oral contraceptive fails due to the interaction with erythromycin. The additional form of contraception should be non-hormonal, such as a barrier method or a copper intrauterine device.
Choice D reason: Avoiding prolonged exposure to direct sunlight is a good advice for anyone taking erythromycin, as it can cause photosensitivity and increase the risk of sunburn. However, this is not related to the interaction with oral contraceptives and does not affect their efficacy.

Correct Answer is ["200"]
Explanation
The correct answer is 200 mL/hr.
Explanation: To calculate the infusion rate, the nurse should use the formula:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
In this case, the volume is 200 mL and the time is 1 hour. Therefore,
Infusion rate (mL/hr) = 200 mL / 1 hr
Infusion rate (mL/hr) = 200 mL/hr
Correct Answer is D
Explanation
Choice A reason: Telling the client to notify the nurse if the pain is not relieved is an important nursing action, but it is not the highest priority. The nurse should assess the client's pain level before and after administering the medication, and evaluate its effectiveness. If the pain is not relieved, the nurse should report it to the prescriber and consider other interventions.
Choice B reason: Advising the client that the medication should start to work in about 30 minutes is an informative nursing action, but it is not the highest priority. The nurse should educate the client about the expected onset, peak, and duration of action of the medication, and how to take it safely and effectively. However, this does not address any immediate risks or needs of the client.
Choice C reason: Administering a stool softener/laxative at the same time as the analgesic is a preventive nursing action, but it is not the highest priority. The nurse should anticipate and prevent potential side effects of the medication, such as constipation, which can be caused by codeine. However, this does not address any urgent or emergent issues of the client.
Choice D reason: Instructing the client to request assistance when ambulating to the bathroom is the highest priority nursing action, as it addresses a serious safety concern of the client. The nurse should protect the client from falls and injuries, which can be caused by codeine's sedative and drowsy effects. The nurse should also monitor the client's respiratory rate and level of consciousness, as codeine can cause respiratory depression and altered mental status.
