Correct Answer: A

Rationale: Administering oxygen is the most appropriate intervention for a patient with confusion post-surgery because it helps alleviate confusion caused by potential hypoxia. In a post-surgical setting, confusion can be a sign of decreased oxygen levels in the blood due to various reasons such as respiratory depression, decreased lung function, or other complications. Administering oxygen can quickly address hypoxia, improving oxygenation to the brain and reducing confusion. Repositioning the patient, administering IV fluids, or performing a neurological assessment are not the primary interventions for confusion related to hypoxia post-surgery.

Correct Answer: D

Rationale: The correct action for the nurse to take in this scenario is to discontinue the oxytocin infusion. With contractions occurring every 90 seconds with a duration of 90 seconds, the contractions are too frequent and prolonged, which can lead to uterine rupture or fetal distress. Increasing or maintaining the oxytocin infusion would exacerbate the situation, potentially causing harm to the mother and fetus. Decreasing the oxytocin infusion might not be sufficient to address the issue, making discontinuation the most appropriate action to ensure the safety of both the client and the baby.

Correct Answer: A

Rationale: Administering oxygen is the priority nursing action for a patient experiencing shortness of breath. Oxygen therapy aims to improve oxygenation levels quickly, addressing the underlying cause of the symptom. Repositioning the patient, checking oxygen saturation, and elevating the head of the bed are important interventions but administering oxygen takes precedence in this scenario to ensure adequate oxygen supply to the body.

Correct Answer: C

Rationale: The correct answer is to instruct the client to sit quietly for 5 minutes before measuring their blood pressure. This allows the body to relax and stabilize, leading to a more accurate reading. Choice A is incorrect because using a cuff that is too loose can result in inaccurate readings. Choice B is incorrect as the cuff should be placed directly on the bare skin. Choice D is incorrect as using the same arm for each reading is important for consistency in monitoring, but sitting quietly before measuring is crucial for accuracy.

Correct Answer: D

Rationale: Correct Answer: The nurse should instruct the patient to wear loose clothing over the radiation site. This helps prevent skin irritation and promotes healing by reducing friction and irritation on the treated area.\nChoice A is incorrect because applying a heating pad can further irritate the skin that is already sensitive due to radiation therapy.\nChoice B is incorrect because scented lotions may contain ingredients that could further irritate the skin.\nChoice C is incorrect because covering the radiation site with a bandage can trap moisture and lead to skin breakdown, increasing the risk of infection.
