Question

1state which parameters - rate, rhythm, amplitude, and quality would be easy to assess via palpation and which would be more challenging to assess via palpation. Briefly explain why for each. 2.Speculate on the adaptive significance of a reduction in peripheral blood flow in cold conditions. How is reduction in peripheral blood flow achieved? 3.People with chronically uncontrolled or poorly controlled diabetes will develop severe peripheral vascular disease. Their blood vessels become damaged and blood flow to their extremities reduces (poor perfusion) a.How does diabetes, left improperly managed, damage peripheral vasculature? b.Diabetics are often instructed to take special care of their feet. They are supposed to avoid injury and be on the lookout for wounds that they might not otherwise have felt. What risks from a foot injury does a diabetic have that an otherwise healthy person not have to worry about?

Explanation / Answer

Rate , rhythms and amplitudes are easy to assess by palpation where quality is challenging.

Rate is assessed by counting Number of beat per minute .calculated ocer right radial pulse.

Normal sinus rhythms is regular.irregular rhythms show phadic variations

Amplitude is measured from volume and waveforms of pulse

2.in cold condition stimulation of posterior hypothalamic sympathetic centres that lead to vasocnostriction of peripheral blood vessels thta leads to decrease in blood flow.

People with diabetic are more prone to atherosclerosis due to excess fat and and glucose.that leads to narrow ing of blood vessels which causes ishchaemia.

Diabetic people have more chance if developing infection because excess glucose in body favour bacterial growth which leads to infection.
