A

Determine proper cuff size and site

Record reading

Thigh

A

Supine position (not ideal) have pt bend knee

S – severity and setting
T – timing

81
Q

When should we assess pain?

A

Often
Always assess pain before procedures, activity and medicate if available
Always re assess pain at least 30 minutes after pain medication has been given
Do not assume to know what your patient’s pain level is….it is what your patient says it is

82
Q

Things to Remember
For VS

A

Nurse is responsible for measurement
Know baseline
Assure equipment is functional
Know history, therapies and medications
Obtain vital signs in a systematic, organized way
Vital signs should be taken at same time every day

83

Safety Guidelines for Skills

A

Cleaning devices
Rotating sites
Analyze trends
Determine the appropriate frequency based on the patient’s condition.
