Correct Answer: B

Rationale: In a client with adrenal crisis presenting with a high temperature, tachycardia, and hypotension, the priority action for the nurse to implement first is to infuse an intravenous fluid bolus. This intervention aims to address the hypotension by increasing the circulating volume and improving perfusion. Obtaining an analgesic prescription (Choice A) is not the priority in this situation. Administering an oral antipyretic (Choice C) may help reduce the fever but does not address the primary issue of hypotension. Covering the client with a cooling blanket (Choice D) may help with temperature control but does not address the hemodynamic instability caused by the adrenal crisis.

Correct Answer: D

Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.

Correct Answer: B

Rationale: The correct recommendation for a client with dry, peeling skin at a radiation therapy treatment site is to use mild soap and water to cleanse the area. This approach helps in preventing skin irritation and reduces the risk of infection. Applying lotion (Choice A) may further irritate the skin due to the chemicals present in the lotion. Covering the area with a sterile dressing (Choice C) is not necessary unless there is an open wound that needs protection. Allowing the skin to air dry after washing (Choice D) may lead to further dryness and peeling.

Correct Answer: B

Rationale: In clients with COPD experiencing difficulty breathing, increasing the client's oxygen flow rate is the priority intervention. This action helps to improve oxygenation and relieve shortness of breath. While bronchodilators and other medications may be necessary, providing immediate oxygen support is crucial. Elevating the head of the bed and repositioning the client can assist with breathing comfort but do not address the immediate need for improved oxygenation in COPD exacerbation.

Correct Answer: B

Rationale: The older brother's withdrawal likely indicates emotional trauma or stress from the near-drowning event. Asking how he felt provides an opportunity for emotional support and allows the child to express feelings that may need addressing. Involving him in supporting the child may be overwhelming and not address his emotional needs directly. Asking the parents for more information may not allow the older brother to express his own feelings. Simply reassuring him that everything is fine now may dismiss his emotional experience without providing a chance for him to process his feelings.
