Rationale: The correct action for the nurse to take when administering medication to a client with a nasogastric (NG) tube is to flush the NG tube with 30 mL of water before administration. Flushing the tube with water helps ensure the patency of the tube and prevents clogging. Choice A is incorrect because administering the medication with a straw is not a recommended practice for NG tube administration. Choice C is incorrect because crushing all medications together may lead to potential drug interactions. Choice D is incorrect because mixing the medication with pudding is not a standard method for administering medication through an NG tube.

Correct Answer: C

Rationale: The correct answer is C. If sterile solution splashes onto the sterile field, it is considered contaminated. Changing gloves in this situation ensures that the sterility of the dressing change is maintained. Choice A is incorrect as non-sterile gloves would introduce contaminants. Choice B is incorrect as layering gloves can increase the risk of contamination. Choice D is incorrect as covering the sterile field with a sterile drape is not the appropriate action to take in response to contamination.

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.

Choice D is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous.

Correct Answer: B

Rationale: The correct answer is B. Wearing cotton socks is essential for clients with diabetes as it helps protect the feet and reduces the risk of skin breakdown.

Choice D is incorrect as applying lotion between the toes can create a moist environment that may increase the risk of fungal infections.
