Correct Answer: A

Rationale: To prevent skin impairment in a patient with a cast, the nurse should assess surfaces exposed to the edges of the cast for pressure areas. This is important to prevent pressure ulcers or skin breakdown. Keeping the patient's blood pressure low (Choice B) is not directly related to preventing skin impairment in this scenario. Allowing turning in bed (Choice C) is essential for preventing complications like pressure ulcers and is not contraindicated. Encouraging the patient's dietary intake (Choice D) to maintain hydration is not directly related to preventing skin impairment associated with a cast.

Correct Answer: D

Rationale: The most crucial action for the nurse to take when caring for a client in restraints is to release the restraints every 2 hours for repositioning. This practice helps prevent complications such as pressure ulcers and impaired circulation by ensuring adequate blood flow and preventing skin breakdown. Checking the client's circulation every hour (Choice A) is important, but releasing the restraints for repositioning takes precedence to prevent serious complications. While documenting the reason for restraints (Choice B) is essential for legal and documentation purposes, it is not as critical as providing necessary care to the client's physical well-being. Providing range-of-motion exercises (Choice C) is beneficial for maintaining mobility but may not address the immediate risks associated with prolonged restraint use.

Correct Answer: A

Rationale: The correct instruction for a patient with stomatitis is to avoid commercial mouthwashes. Commercial mouthwashes often contain alcohol and other ingredients that can irritate the already inflamed oral mucosa in patients with stomatitis. Avoiding commercial mouthwashes helps prevent further irritation and discomfort. Choice B is incorrect because normal saline rinses are gentle and can help soothe the oral mucosa in patients with stomatitis. Choice C is incorrect because a soft toothbrush should be used to prevent further irritation or injury to the gums. Choice D is incorrect because an alcohol-based toothpaste can be too harsh and drying for patients with stomatitis.

Correct Answer: B

Rationale: The correct response is to instruct the client that the stoma will become smaller when the initial swelling diminishes. This explanation helps reassure the client about the temporary appearance of the stoma. Choice A is incorrect because simply reassuring the client that he will become accustomed to the stoma's appearance does not address the immediate concern about the stoma size. Choice C is incorrect because offering to contact a support group does not directly address the client's current distress about the stoma size. Choice D is incorrect because encouraging the client to handle stoma equipment does not directly address the client's concern about the stoma size and may not be appropriate at this time.

Correct Answer: D

Rationale: The correct answer is to proceed with the triage process in the same manner as any adult client. In this scenario, since the teenager is legally married, they have the legal authority to consent to their own treatment. Choice A is incorrect because the teenager, being legally married, can provide their own consent. Choice B is incorrect as it unnecessarily delays treatment by waiting for telephone consent from the partner, which is not required in this case. Choice C is incorrect as the teenager can receive appropriate care in the current emergency department setting without the need for referral.
