During the physical assessment, the nurse asks an elderly female patient if she experiences constipation. The nurse knows that

It is common for intestinal peristalsis to slow down as a person ages, causing problems with constipation.

Aging patients always have difficulty having a bowel movement while hospitalized

Elderly patients almost always abuse laxatives, which creates problems with constipation.

In elderly patients, the rectal sphincter has lost elasticity, which decreases the sensation of urgency.

Answer and Explanation

The Correct Answer is A

A: Due to age-related reductions in gastrointestinal muscle efficiency, which slows the digestive process and can lead to increased water absorption from stool.
B: Overstates the issue, not all elderly patients experience difficulties, and it does not account for individual variability or other influencing factors like diet and medication.
C: Misrepresents the frequency and reasons for laxative use among the elderly, not all of whom misuse these medications.

B: Evaporation is the process where liquid (sweat) turns into vapor, removing heat from the surface it evaporates from, which is the primary cooling mechanism in sweating.
C: Conduction involves direct transfer of heat through contact with cooler objects, not relevant to the drying of sweat.
D: Radiation refers to heat transfer through electromagnetic waves and does not require the presence of an intervening medium, unlike the evaporation of sweat.
