A nurse is caring for an older adult client who has a hearing aid.
Which of the following actions should the nurse take when the client reports hearing a whistling sound from the hearing aid?

Choice A rationale

Hypermagnesemia is less common with vomiting and diarrhea. These conditions usually cause a loss of magnesium rather than an excess.

Choice B rationale

Hyperkalemia is also less typical. Vomiting and diarrhea tend to cause potassium loss, leading to hypokalemia instead.

Choice C rationale

Hyponatremia is common as vomiting and diarrhea result in the loss of sodium and water, leading to low blood sodium levels.

Choice D rationale

Hypocalcemia is not a primary result of vomiting and diarrhea. Calcium levels are usually not directly affected by gastrointestinal fluid loss.

Choice A rationale

Standing with the crutch tips against the feet is incorrect. Proper crutch placement involves positioning the crutches slightly forward and to the side of the feet to provide stability and prevent tripping.

Choice B rationale

Bearing weight on the unaffected leg is the correct instruction for using the three-point gait. This technique allows the client to move the crutches and the affected leg together while bearing weight on the unaffected leg, promoting balance and mobility.

Choice C rationale

Keeping the crutches at the level of the axillae is incorrect. Crutches should be positioned with a 1-2 inch gap below the axillae to prevent nerve damage and ensure proper support.

Choice D rationale

Holding the arms straight when walking is incorrect. The elbows should be slightly bent to allow for comfortable movement and better control of the crutches.
