Which of the following should the nurse perform to assess the arterial function of the lower extremities?

Assess for pretibial edema

Palpate pedal pulses bilaterally

Allen test

Homan sign

Answer and Explanation

The Correct Answer is B

A. Pretibial edema: Edema is more indicative of venous function, not arterial function.

B. Palpate pedal pulses bilaterally: Palpation of the pedal pulses is essential to assess arterial circulation in the lower extremities.

C. Allen test: This assesses arterial blood flow to the hand, not the lower extremities.

D. Homan sign: Homan sign is used (though controversial) to assess for deep vein thrombosis (DVT), which is related to venous, not arterial, function.

Explanation

New Nurse Statement	Met	Not Met
I will confirm the patient's pupil size with the scale on the side of the penlight.	✅
When putting the penlight at the bridge of the nose, the eyes converge and constrict	✅
I will check the patient's pupillary reflex by shining a light into their eyes.	✅
When shining the penlight into the patient's eyes, their pupils should dilate		✅

Rationale:

"I will confirm the patient's pupil size with the scale on the side of the penlight" (Met):

This is a correct use of the penlight to assess pupil size and document findings accurately.

"When putting the penlight at the bridge of the nose, the eyes converge and constrict" (Met):

This statement describes the normal accommodation reflex, where the eyes converge and pupils constrict when focusing on a near object.

"I will check the patient's pupillary reflex by shining a light into their eyes" (Met):

This correctly describes testing for the pupillary light reflex, where the pupil constricts in response to light.

"When shining the penlight into the patient's eyes, their pupils should dilate" (Not Met):

This is incorrect. The pupils should constrict in response to light, not dilate. Dilation occurs in response to low light or sympathetic stimulation.

A. Progressive atrophy of the intramuscular calf veins, causing venous insufficiency B. Narrowing of the inferior vena cava, causing low blood flow and increases in venous pressure resulting in varicosities. C. Peripheral blood vessels growing more rigid with age, producing a rise in systolic blood pressure D. Hormonal changes causing vasodilation and a resulting drop in blood pressure

Correct Answer is C

Explanation

A. Atrophy of calf veins: Vein atrophy is not a normal aging process, although venous insufficiency is common due to other causes.

B. Narrowing of the inferior vena cava: This is not a typical age-related change.

C. Peripheral blood vessels growing more rigid: Arteriosclerosis (hardening of the arteries) is common with aging and leads to increased systolic blood pressure.

D. Hormonal changes causing vasodilation: Aging tends to cause vascular rigidity, not vasodilation, and is more likely to lead to hypertension.
