Which of the following assessment(s) is/are considered reliable in the older adult? (Select all that apply.)

Choice A reason: Overhydration is not the definition of the promotion of an adequate fluid balance, but rather a condition where the body has excess fluid volume, which can cause medical complications, such as edema, hyponatremia, or heart failure.
Choice B reason: Dehydration is not the definition of the promotion of an adequate fluid balance, but rather a condition where the body has insufficient fluid volume, which can cause medical complications, such as hypotension, tachycardia, or kidney failure.
Choice C reason: Hypernatremia is not the definition of the promotion of an adequate fluid balance, but rather a condition where the body has excess sodium concentration in the blood, which can cause medical complications, such as thirst, confusion, or seizures.
Choice D reason: Hydration is the definition of the promotion of an adequate fluid balance, as it refers to the maintenance of the optimal amount and distribution of fluid in the body, which can prevent medical complications, such as dehydration, electrolyte imbalance, or infection.

Choice A reason: The classic signs of elevated glucose levels, polyuria, polyphagia, and polydipsia are rarely present in older adults is true because older adults may have impaired thirst sensation, reduced appetite, or altered renal function that can mask these symptoms. They may also have other chronic conditions or medications that can affect their glucose levels or urine output.

Choice B reason: Older adults tend to metabolize glucose at a faster rate than younger adults is false because older adults usually have a slower metabolism and a reduced insulin sensitivity that can impair their glucose regulation. They may also have less muscle mass and more fat tissue that can affect their glucose utilization.

Choice C reason: Fingerstick glucose monitoring is inaccurate in older adults is false because fingerstick glucose monitoring is a reliable and convenient method to measure blood glucose levels in older adults, as long as they follow the proper technique and calibration. They may also benefit from using devices that have larger displays, voice output, or memory functions.

Choice D reason: There is a higher tolerance for elevated levels of circulating glucose in older adults is false because elevated levels of circulating glucose can cause serious complications in older adults, such as cardiovascular disease, kidney disease, nerve damage, or infections. Older adults may have a higher risk of developing these complications due to their age, comorbidities, or frailty.
