Which of the following is a true statement about assistive devices to aid older adults with impaired mobility?

Choice A reason: Use of a commode close by to where the client spends most of his time can reduce the distance and time required for the client to reach the toilet, and thus prevent accidents and embarrassment. It can also promote the client's independence and dignity.

Choice B reason: Development of a toileting schedule can help the client to establish a routine and habit of voiding at regular intervals, and thus prevent the bladder from becoming too full or overactive. It can also reduce the risk of urinary tract infections and skin breakdown.

Choice C reason: Use of an external catheter is not recommended for older adults with dementia, as it can cause irritation, infection, and obstruction of the urinary tract. It can also increase the client's confusion and agitation, and interfere with his mobility and comfort.

Choice D reason: Bladder diary to be completed by the client's wife is not a direct intervention to manage the incontinence, but rather a tool to assess the pattern and severity of the problem. It can help the nurse to identify the possible causes and triggers of the incontinence, and to evaluate the effectiveness of the interventions. However, it may not be feasible or reliable for the client's wife to complete the diary, as she may have other responsibilities or difficulties in observing and recording the client's urinary habits.

Choice A reason: Over-the-counter NSAIDs are generally harmless is not a true statement, as NSAIDs can cause serious adverse effects in older adults, such as gastrointestinal bleeding, renal impairment, hypertension, and heart failure. NSAIDs should be used with caution and under medical supervision in older adults.

Choice B reason: Stool softeners and laxatives should be used with opioids is a true statement, as opioids can cause constipation in older adults, which can lead to discomfort, abdominal pain, fecal impaction, and bowel obstruction. Stool softeners and laxatives can help prevent and treat constipation and promote regular bowel movements.

Choice C reason: Opioids are less effective in older clients than in younger clients is not a true statement, as opioids can have the same or even greater analgesic effect in older adults, depending on the dose, route, and duration of administration. However, opioids can also cause more side effects in older adults, such as sedation, confusion, respiratory depression, and falls. Opioids should be used with caution and under medical supervision in older adults.

Choice D reason: The dose limit for acetaminophen is difficult to reach for older adults is not a true statement, as older adults may be more susceptible to acetaminophen toxicity, especially if they have liver disease, malnutrition, or chronic alcohol use. The dose limit for acetaminophen is 4 grams per day for adults, but it may be lower for older adults or those with risk factors. Acetaminophen should be used with caution and under medical supervision in older adults.
