2)"The heart of an older client may have some degree of diastolic dysfunction."
3)"A higher response of baroreceptors in arterioles is seen with increasing age."

2)Atherosclerosis
3)Diabetes mellitus
4)Both C and B

Question 11

Which change in the integumentary system of older clients is responsible for difficulties in thermoregulation?

2)Fewer sebaceous glands
3)Decreased function of melanocytes
4)Increased fragility of small blood vessels in the skin

Question 12

While reviewing the medical history of a client with diabetes,a nurse finds that the client has impaired renal function.Which medication in the client's prescription does the nurse suspect to be replaced?
1)Aspirin
2)Metformin
3)Insulin lispro
4)None of the above

Question 13

An older client is frequently complaining of constipation to a nurse.Which age-related change in the gastrointestinal system does the nurse suspect to be the cause?
1)Stomach lining atrophies
2)Diminished amount of lactase enzyme
3)Loss of strength of the lower esophageal sphincter
4)Denervation in the distal portion of the gastrointestinal tract

Question 14

Flattened villi of the intestine in older adults causes
1)Pain in the lower quadrant of the abdomen.
2)Indigestion,gas accumulation,and diarrhea.
3)Changes in the composition of the intestinal flora.

1)Pick's disease
2)Vascular dementia
3)Alzheimer's disease
4)Dementia with Lewy bodies

Question 16
