Correct Answer: B

Rationale: When a client reports pain and redness at the site of a peripheral IV, indicating signs of phlebitis, the nurse's initial action should be to discontinue the IV line. This helps prevent further complications and ensures patient safety. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider (Choice C) is important but not the initial step. Increasing the IV flow rate (Choice D) can exacerbate the inflammation and should be avoided.

Correct Answer: B

Rationale: The correct answer is to auscultate bowel sounds. This action should be taken first because it ensures that bowel sounds are not altered by physical manipulation. Inspecting the abdomen (choice C) may provide visual cues but does not address functional assessment. Palpating the abdomen (choice A) should follow auscultation to prevent altering bowel sounds. Percussing the abdomen (choice D) is typically done after auscultation and palpation.

Correct Answer: B

Rationale: The correct answer is B: Eye contact, personal space, and touch are cultural variables that can influence healthcare interactions. These factors vary across cultures and can impact how individuals perceive communication and interactions. Choices A, C, and D include elements that are not specifically cultural variables affecting communication and interactions in the same way as eye contact, personal space, and touch.

Correct Answer: B

Rationale: The correct instruction the nurse should include when teaching a client about using a metered-dose inhaler (MDI) is to hold the inhaler 1-2 inches from the mouth. This distance ensures proper delivery of the medication into the airways. Choices A, C, and D are incorrect because inhaling for a specific duration, exhaling immediately after inhaling, or holding the inhaler directly at the lips are not recommended practices for the correct use of an MDI.

Correct Answer: B

Rationale: The correct answer is B: 'Ensure the cane has a rubber tip.' This instruction is essential for safety as the rubber tip prevents slipping, providing stability. Choice A is incorrect because the cane should be held on the stronger side to provide better support and balance. Choice C is incorrect as the cane should be used on the stronger, more dominant side. Choice D is also incorrect as a cane is not only used on stairs but also for general support and mobility.
