Correct Answer: A

Rationale: For a client who has undergone an allogeneic stem cell transplant, it is crucial to maintain a protective environment to prevent infections. Wearing a mask when outside the room, especially if there is construction in the area, helps reduce the risk of exposure to harmful pathogens. This precaution is essential as the client's immune system is compromised post-transplant. Placing the client in a room with other immunocompromised patients (choice B) would increase the risk of infections as it exposes the client to a higher pathogen load. Allowing the client to visit public areas freely (choice C) is not recommended due to the higher risk of exposure to infections. Ensuring the client does not need any special precautions (choice D) is incorrect because clients post allogeneic stem cell transplant require protective measures to prevent complications.

Correct Answer: A

Rationale: The correct action the nurse should take first is to auscultate bowel sounds. This step is crucial to assess bowel activity before proceeding with palpation or administering medications. Assessing bowel sounds can provide valuable information about bowel motility and potential obstructions. Administering an antiemetic or offering pain medication may be necessary but should come after assessing bowel sounds to ensure appropriate treatment. Palpating the abdomen should be avoided initially to prevent potential discomfort or complications, especially if there is suspected abdominal pathology.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to notify the provider about the client's decision. By informing the provider, they can discuss the client's change in decision, explore the reasons behind it, and determine the appropriate course of action. Proceeding with the transport (Choice B) without addressing the client's concerns would not respect the client's autonomy and right to make decisions about their own healthcare. Preparing the surgical site (Choice C) would be premature and inappropriate if the client no longer wishes to proceed with the surgery. While documenting the client's statement (Choice D) is important for documentation purposes, the immediate priority is to involve the provider in the decision-making process.

Correct Answer: B

Rationale: The correct answer is B, 'Allergic to shellfish.' An allergy to shellfish can indicate a sensitivity to iodine, which is used in the contrast dye for an IVP, posing a risk of an allergic reaction. Reflex incontinence (Choice A) is not directly related to the potential hazard of an IVP. Claustrophobia (Choice C) and hypertension (Choice D) are also not significant factors that indicate a potential hazard for an IVP.

Correct Answer: A

Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.
