The nurse is taking care of a 80-year-old patient whose blood pressure is 156/96 mm Hg. What is an age-related cause of this blood pressure?
Arteries dilate, lengthen, and become more rigid
Chronic hypoxic state of the brain
Arteries constrict, lengthen and become more rigid.
Decreased heart rate and stroke volume
The Correct Answer is C
A. Arteries dilate, lengthen, and become more rigid
Arteries do not typically dilate; they narrow and stiffen with age.
B. Chronic hypoxic state of the brain
May affect mental function, not a direct cause of high BP.
C. Arteries constrict, lengthen and become more rigid
Arterial stiffness and loss of elasticity increase systemic vascular resistance, contributing to hypertension.
D. Decreased heart rate and stroke volume
May occur, but these typically cause lower, not higher, blood pressure.

Correct Answer is D
Explanation
A. Slower gastric emptying of fluid
This affects digestion, not necessarily bowel motility or stool formation. It is not the primary factor in constipation.
B. Decreased hydrochloric acid
This may impair digestion but is not directly responsible for constipation.
C. Abdominal bloating
Bloating is more of a symptom than a cause. It may occur after constipation develops.
D. Lack of dietary fiber
Older adults often consume less fiber, which is crucial for stool bulk and regular bowel movements. Low fiber intake is a leading contributor to constipation.
