remember about privacy rules, it was really important when i was taken my cna exam. doors, curtains, windows if any need to be close.
handwashing after and before any procedure or task,
identify yourself to resident and tell what you going to do,
keep environment, resident, yourself as safe as you can,
gloves using if needed, mask,
proper body mechanics,
when you clean person - uncovered only the part which you clean, that was important when i passed my exam,
i always prepare extra stuffs in case emergency, like towel, gloves, blankets, spreadsheet, bluesheet, diaper,
try to not cut person, not to pull hair,
if person is able you can ask if she or he wants to do something on own,
that what i remember.
