Correct Answer: C

Rationale: Repositioning the client every 2 hours is a crucial intervention in the management of pressure ulcers. This action helps redistribute pressure, reducing the risk of further skin breakdown and promoting wound healing. Massaging the ulcer can cause further damage to the skin and underlying tissues. Applying a heating pad can increase the risk of skin breakdown and should be avoided. Alcohol-based cleansers are too harsh for pressure ulcers and can irritate the skin, potentially delaying healing.

Correct Answer: C

Rationale: Inspecting the feet daily is crucial for clients with diabetes mellitus to detect early signs of injury or infection promptly. This practice helps prevent serious complications such as diabetic foot ulcers. Soaking feet in hot water daily can lead to skin dryness and increase the risk of injury. Applying lotion between toes can cause moisture buildup, leading to fungal infections. Using over-the-counter products to remove corns can result in skin damage and should be done under healthcare provider supervision.

Correct Answer: C

Rationale: Applying a transparent dressing over the heel is beneficial as it can protect the ulcer from friction and shear, and allow for continuous observation of the wound. This intervention promotes healing and prevents further damage to the skin.

Correct Answer: C

Rationale: When administering an intradermal injection, a tuberculin syringe is the appropriate choice due to its small size and precise measurement markings, which are essential for accurately delivering the medication into the dermis layer of the skin. Using a 1-inch needle (choice A) is more common for subcutaneous injections, while inserting the needle at a 45-degree angle (choice B) is typical for intramuscular injections. Aspirating before injecting (choice D) is not necessary for intradermal injections, as the goal is to deliver the medication into the dermis rather than a blood vessel.

Correct Answer: D

Rationale: Flushing the NG tube with water before and after administering medications is essential to prevent clogging of the tube and ensure proper delivery of medication. This practice helps maintain tube patency and decreases the risk of obstruction, which could compromise the client's treatment and nutrition. By flushing the tube, the healthcare provider ensures that the medication is completely delivered and that there are no residual drug particles left in the tube, which could lead to blockages or inconsistent dosing. Therefore, flushing the NG tube is a crucial step in the safe administration of medications to clients receiving enteral feedings.
