Answer to Question 1
ANS: B, D
Peripheral perfusion assessment includes noting loss of hair on lower legs, denoting decreased circulation. When assessing peripheral perfusion, the pedal pulses in the lower extremities are assessed in conjunction with skin color and temperature. Heart rate and rhythm are components of assessment of the cardiovascular system but not associated with peripheral tissue perfusion. Pupil reaction is considered a neurologic assessment.
Answer to Question 2
ANS: D
The Doppler ultrasound device may aid in determining peripheral blood flow. This is not a sufficient cause to notify the health care provider and does not warrant radiologic examination without further assessment. Positioning will not affect the assessment of pedal pulses.
