Q

Age-related changes in cardiac physiology are minimal

True- why?

Cardiac physiology changes that DO occur affect what?

A

Age-related changes in cardiac physiology are minimal, and the changes that do occur affect cardiac performance only under conditions of physiologic stress.

Q

Age-related changes in cardiac physiology are minimal

True-

Under stressful conditions, the how is the heart in healthy older adults? How does it differ in younger adult hearts?

A

Even under stressful conditions, the heart in healthy older adults is able to adapt, but the adaptive mechanisms may differ from those of younger adults or be slightly less efficient

Essential to assess for hypotension

23
Q

Nursing Assessment of Cardiovascular Function:

What should be addressed?

A

Technology to promote wellness in older adults

28
Q

What is white coat hypertension?

A

Elevated blood pressure readings during a visit to the healthcare provider

White coat hypertension (also called isolated office hypertension), which is the phenomenon of blood pressure readings being high only when checked by a health care practitioner

29
Q

Nursing Assessment of Cardiovascular Function

Identify risks for cardiovascular disease-like?
