The nurse assigns the diagnosis of Nutrition Imbalance: less than body requirements for an older adult. Which age-associated intestinal problem does the nurse apply to plan goals and interventions to improve this adult's nutritional status?
a. Less intrinsic factor secretion
b. Short, broad small intestinal villi
c. Decreased gastric smooth muscle
d. Decreased large intestinal motility
B
Feedback
A Incorrect. Decreased intrinsic factor secretion leads to pernicious anemia due to inability to absorb vitamin B12 in the stomach.
B Correct. Villi of the small intestine shorten and widen with age and, as a result, become less functional. This contributes to malabsorption of nutrients despite a healthy diet because nutrients are absorbed primarily in the small intestines. The concept of malabsorption is what the nurse uses to plan care, because this nurs-ing diagnosis refers to inability of the body to absorb nutrients due to biological factors.
C Incorrect. Gastric smooth muscle is not present in the intestines.
D Incorrect. Decreased large intestine motility is an age-associated problem; how-ever, this should have no impact on absorption in the small intestine.
