Related: Blood pressure, Intake and output
Blood pressure

The force of blood pushing against artery walls, written as two numbers (systolic over diastolic). It is measured with a cuff and gauge, and unusual readings are reported to the nurse promptly.

Intake and output

A record of all fluids a resident drinks or receives and all urine, vomit, or drainage released. Careful measuring helps the team recognize dehydration or fluid buildup.

Related: Vital signs, Catheter care

Cleaning and checking an indwelling urinary tube and the skin around it to prevent infection. The nursing assistant keeps the bag below bladder level and reports cloudy urine, leaks, or odor.

Related: Intake and output, Standard precautions
