Correct Answer: D

Rationale: The most important intervention for a client with rheumatoid arthritis is to assist with heat application and range of motion exercises. Heat application helps reduce stiffness and improve joint flexibility, while range of motion exercises help maintain mobility and prevent contractures. Massaging inflamed joints with creams and oils may provide temporary relief but does not address the root cause of stiffness and limited mobility in rheumatoid arthritis. Providing support to flexed joints with pillows and pads can be helpful for comfort but does not actively promote mobility. Positioning the client on their abdomen several times a day is not a standard intervention for managing rheumatoid arthritis.

Correct Answer: C

Rationale: The correct intervention for a client at risk for pressure ulcers is to turn and reposition the client every 2 hours. This helps relieve pressure on bony prominences, improving circulation and reducing the risk of pressure ulcer development. Applying heat to the affected area (Choice A) can increase the risk of skin breakdown. Placing the client in a prone position (Choice B) can also increase pressure on certain areas, leading to pressure ulcers. Providing the client with a bedpan every 4 hours (Choice D) is not directly related to preventing pressure ulcers.

Correct Answer: B

Rationale: The most appropriate intervention for a client with phlebitis at the IV site is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and continuing the IV can lead to complications such as infection or thrombosis. Applying a warm compress may provide symptomatic relief but does not address the root cause. Increasing the IV flow rate is not indicated and may worsen the inflammation. Monitoring for signs of infection is important, but the priority is to remove the source of inflammation by discontinuing the IV.

Correct Answer: A

Rationale: The correct answer is A: Yankauer catheter. The Yankauer catheter is specifically designed for oral suctioning, making it the most appropriate choice for this task. Choice B, the Bulb syringe, is typically used for suctioning small amounts of liquid from the nose or mouth. Choice C, the Suction catheter, is more commonly used for deep suctioning in the trachea or bronchi. Choice D, Sterile gloves, are necessary for infection control but are not the primary supply used for oral suctioning.

Correct Answer: C

Rationale: The correct instruction for a client with left-leg weakness using a cane is to maintain two points of support on the floor at all times. This technique provides stability and support while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice B is incorrect as advancing the cane and the strong leg together may not provide adequate support and balance. Choice D is incorrect as the distance to advance the cane with each step can vary depending on the individual's needs and abilities.
