A nurse is caring for a client in the ICU. The client's ECG monitor tracing reveals sinus bradycardia and ST-segment elevation. The client reports shortness of breath and feeling dizzy and faint. Which of the following medications should the nurse administer?

Choice A reason: Changing the ostomy pouch daily is not typically necessary. Most pouches can be worn comfortably for several days before needing to be changed. Frequent changes are not only unnecessary but can also irritate the skin around the stoma.

Choice B reason: Emptying the ostomy pouch when it is 2/3 full is recommended to prevent leaks and overfilling, which can lead to discomfort and potential skin irritation. It is important to monitor the fullness of the pouch and empty it regularly to maintain hygiene and comfort.

Choice C reason: Trimming the opening of the ostomy seal to be 1/2 inch wider than the stoma is incorrect. The opening should be cut to match the size of the stoma to ensure a snug fit that prevents leakage and protects the skin around the stoma.

Choice D reason: Applying lotion to the peristomal skin when changing the ostomy pouch is not advised. Lotions or creams can interfere with the adhesive of the ostomy appliance and should be avoided. The peristomal skin should be clean and dry to ensure proper adhesion of the ostomy appliance.

Choice A reason: Placing the client's bed at the lowest height is a safety intervention that minimizes the risk of injury from falls, which is particularly important for clients with dementia who may have impaired mobility or judgment. Lowering the bed height can reduce the severity of an injury if a fall does occur. Additionally, it can facilitate easier access for the client to get in and out of bed with less assistance.

Choice B reason: Requesting a prescription for a nightly sedative is not typically recommended as a first-line intervention for clients with dementia. Sedatives can increase the risk of confusion, falls, and can worsen cognitive impairment in the elderly. Non-pharmacological approaches are preferred for managing sleep disturbances in dementia patients.

Choice C reason: Assisting the client with toileting at least once every 4 hours is an important intervention to maintain hygiene and comfort, as well as to prevent urinary tract infections and skin breakdown. However, the frequency of toileting assistance should be individualized based on the client's needs and level of incontinence.

Choice D reason: Turning off all lights in the client's room at night is not advisable as some clients with dementia may experience increased confusion or agitation in complete darkness. A nightlight or low-level lighting can provide a safer environment and help to orient the client during nighttime hours.
