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 D
Explanation
Choice A reason: Chest tube insertion is not indicated for respiratory depression caused by opioid overdose. It is a procedure used to treat pneumothorax, hemothorax, or pleural effusion.
Choice B reason: CPR is not the first-line intervention for respiratory depression. It is only indicated when the client has no pulse or signs of life.
Choice C reason: Glasgow Coma Scale score is a tool to assess the level of consciousness of a client. It is not an intervention that can reverse respiratory depression.
Choice D reason: Naloxone is an opioid antagonist that can reverse the effects of opioid overdose. It has a short half-life and may need to be repeated if the client's condition does not improve or worsens.
Correct Answer is C
Explanation
Choice B reason: Naloxone may be necessary, but first, the source of overdose (patches) must be removed to prevent further opioid absorption. After removal, the nurse should assess the severity and then administer naloxone if needed.
Choice A reason: Applying oxygen face mask is not the first action that the nurse should take in this situation, but rather a supportive measure that can be done after administering naloxone. Oxygen can help to improve the client's oxygenation and prevent hypoxia, but it will not reverse the opioid overdose.
Choice C reason: The client is exhibiting signs of opioid overdose, including respiratory depression (shortness of breath) and decreased level of consciousness (difficult to arouse). The first priority is to remove the excess morphine patches to stop further opioid absorption and prevent worsening of the overdose.
Choice D reason: Monitoring blood pressure is not the first action that the nurse should take in this situation, but rather an ongoing assessment that can be done after administering naloxone. Monitoring blood pressure can help to detect any changes in the client's hemodynamic status and guide further interventions, but it will not reverse the opioid overdose.
