Correct Answer: D

Rationale: The priority action for the nurse is to address the client's immediate physiological need for comfort and pain relief during the dressing change. Administering pain medication 45 minutes before the procedure can help alleviate the pain experienced by the client. Encouraging relaxation techniques (choice A) is beneficial but may not provide sufficient pain relief during the dressing change. Educating about the importance of pain management (choice B) is relevant but does not address the immediate need for pain relief. Assisting the client to a comfortable position (choice C) is helpful but does not directly address the client's pain concern during the dressing change. Administering pain medication is the most direct and effective intervention to ensure optimal client comfort and compliance with necessary procedures.

Correct Answer: A

Rationale: The correct response is A: 'When the GI tract is working again, in about three to five days, the tube can be removed.' After a partial colectomy, the GI tract needs time to recover and start functioning properly. The NG tube is typically removed when peristalsis returns, indicating GI function restoration, which usually occurs within 3-5 days post-op. Choice B is incorrect because the removal of the NG tube is not solely based on nausea improvement. Choice C is incorrect as it provides a longer duration for tube removal than is usually necessary. Choice D is incorrect as the cessation of drainage alone does not dictate NG tube removal; the return of GI function is the primary indicator.

Correct Answer: A

Rationale: The correct answer is to assess the oral cavity. 'Edentulous' means without teeth, so the nurse should assess the oral cavity for any issues related to oral health, dentures, or potential complications. This assessment is crucial to prevent oral health problems and ensure proper care for the patient. Assessing the room for drafts (choice B) is unrelated to the patient's edentulous status and does not address the immediate care needs. Assessing ankles for edema (choice C) is important for circulatory assessment but not directly related to the patient being edentulous. Assessing for reduced sensations (choice D) would be more relevant for neurological or sensory concerns, which are not specifically associated with being edentulous.

Correct Answer: D

Rationale: When a nurse observes peristomal skin irritation while changing a client's colostomy pouch, it is crucial to ensure that the pouch is slightly larger (0.32 cm or 1/8 inch) than the stoma. This extra space helps prevent the pouch from rubbing against the stoma and causing further irritation. Option A is correct because colostomy pouches should be changed based on individual needs, not necessarily every 24 hours. Option B is incorrect because applying the pouch only when the skin barrier is completely dry ensures better adhesion. Option C is incorrect as patting the peristomal skin dry after cleaning is more gentle and less likely to cause irritation compared to rubbing.

Correct Answer: C

Rationale: Dehydration is the primary factor to consider in this scenario. Dehydration leads to decreased skin turgor and tenting, where the skin does not return to its normal position when pinched. While thin, parchment-like skin, loss of adipose tissue, and diminished skin elasticity can contribute to skin changes, they are not the primary cause of the significant tenting observed.
