A hospitalized older adult who recently had surgery and a wound infection postoperatively is noted to be losing weight despite consuming his meal trays and snacks. One reason that this might be occurring is:
a. an injury may trigger inflammatory medi-ators that increase metabolic rate and im-pair nutrient utilization.
b. an injury may cause malabsorption of nu-trients.
c. most hospitalized older patients do not consume adequate amounts of micro- and macronutrients.
d. most hospitalized patients do not have accurate weights recorded upon admis-sion.
ANS: A
One trajectory for malnutrition is inflammation-related malnutrition; in this situation, malnutrition develops as a consequence of injury, surgery, or disease that triggers inflammatory mediators that contribute to an increased metabolic rate and impaired nutrient utilization. An injury does not necessarily cause malabsorption of nutrients. There is no evidence that most hospitalized patients do not consume adequate diets, and there is also no evidence that accurate weights are not rec-orded for most hospitalized patients.
