Correct Answer: B

Rationale: The correct technique when performing nasotracheal suctioning is to apply intermittent suction when withdrawing the catheter. This method helps reduce trauma to the mucosa by preventing prolonged suctioning. Choice A is incorrect because inserting the suction catheter while the client is swallowing may increase the risk of aspiration. Choice C is incorrect as placing the catheter in a clean, dry location for later use is not a safe practice as it can lead to contamination. Choice D is incorrect since it does not address the proper technique involved in nasotracheal suctioning.

Correct Answer: B

Rationale: Encouraging the client to gradually resume self-care tasks with rest periods is the best strategy to promote independence in self-care for a client with acute myocardial infarction. This approach allows the client to regain independence while considering the need for rest to prevent overexertion. Instructing the client to limit all activity until fully rested (Choice A) may hinder independence by promoting inactivity. Assigning assistive personnel to complete self-care tasks (Choice C) does not promote the client's independence. Asking the client's family to assist with self-care (Choice D) may not foster the client's self-reliance and may not always be feasible.

Correct Answer: B

Rationale: The correct answer is to keep the home environment warm. Raynaud's disease causes vasospasm in response to cold, so maintaining a warm environment can help prevent attacks. Choices A, C, and D are incorrect. Increasing potassium intake, elevating legs when sitting, or reducing sodium intake are not specific to managing Raynaud's disease.

Correct Answer: D

Rationale: Option D is the most appropriate response as it acknowledges the client's expressed uncertainty about the surgery. By acknowledging the client's feelings, the nurse validates their concerns and opens the door for further discussion. This approach can help build trust and rapport with the client. Option A focuses more on seeking justification for the client's belief rather than addressing the underlying emotion. Option B, while acknowledging doubt, does not directly address the client's feelings. Option C, although well-intentioned, dismisses the client's concerns without exploring them further.

Correct Answer: A

Rationale: The correct nursing intervention for a patient with a pressure ulcer is to clean the wound and apply a hydrocolloid dressing. This promotes healing by creating a moist environment conducive to the wound healing process. Choice B is incorrect because while nutrition is important for wound healing, a high-protein diet alone is not a specific intervention for a pressure ulcer. Choice C is incorrect as antibiotics are only used if there is an infection present. Choice D is also incorrect as a low-sodium diet and monitoring for fluid retention are more related to conditions like heart failure or kidney disease, not specifically pressure ulcer care.
