When evaluating the radial pulse measurement technique of the nursing assistant,the nurse identifies appropriate technique when the assistant:

A) has the patient's arm elevated.
B) positions the patient supine or sitting.
C) applies significant pressure to the pulse site.
D) counts the pulse for 15 seconds and multiplies by 4.

Assist the patient to assume a supine or sitting position.If the patient is supine,place the patient's forearm straight alongside or across the lower chest or upper abdomen with the wrist extended straight.If the patient is sitting,bend the patient's elbow 90 degrees and support the lower arm on the chair or on the nurse's arm.Slightly extend or flex the wrist with the palm down until the strongest pulse is noted.Lightly compress against the radius,obliterate the pulse initially,and then relax pressure so the pulse becomes easily palpable.Pulse is assessed more accurately with moderate pressure.Too much pressure occludes the pulse and impairs blood flow.If the pulse is regular,count the rate for 30 seconds and multiply the total by 2.If the pulse is irregular,count the rate for 60 seconds.Assess frequency and pattern of irregularity.
