What is the best teaching point for a client with left-leg weakness learning to use a cane?

Correct Answer: B

Rationale: The correct teaching point for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures better stability and support for the client while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice C is incorrect as advancing the cane too far with each step may compromise balance. Choice D is incorrect because advancing the cane and the strong leg together may not provide adequate support for the weaker leg.

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: 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: A

Rationale: The correct intervention for a client with hyperkalemia is to administer calcium gluconate. Calcium gluconate helps counteract the effects of hyperkalemia by stabilizing the cardiac cell membrane. Increasing fluid intake (Choice B) may not effectively lower potassium levels. Administering a diuretic (Choice C) or sodium bicarbonate (Choice D) is not the primary treatment for hyperkalemia and may not address the immediate need to lower potassium levels.

Correct Answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This action helps stimulate voiding post-catheterization by promoting relaxation and providing sensory input. Assessing for bladder distention after 6 hours (Choice A) is important but not the immediate intervention needed for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not effectively address the issue of post-catheterization voiding difficulty. Restricting the client's intake of oral fluids (Choice C) is not appropriate and can lead to dehydration, which is not helpful in promoting voiding.
