Q

what are guidelines for the low cholesterol diet?

A

high fiber foods have been found to lower cholesterol and should be incorporated in the low cholesterol diet (oatmeal)

35
Q

what is one reason to limit chair sitting to one hour?

lower extremity edema

36
Q

what are important interventions for a client sitting in a chair?

A

limit time to one hour

shift weight every 15 min and use a cushion to decrease pressure

nonskid socks
proper fitting shoes
bed locked and lowered
hourly rounding to offer toilet
ensure high use items are close by
call light within reach
two head side rails up

sensory aids in
assistive devices being used

38
Q

what side is the cane used on?

A

the unaffected/strong side

39
Q

what is the 3-point gait?

A

requires the client to bear all weight on strong leg/side

  • client moves both crutches with the weak leg forward and then moves the strong leg
40
Q

if you are teaching a client the 3-point gait and they move the strong leg first, is this correct?

A

no, move weak leg

41
Q

what are some symptoms of DVT?

A

swelling
redness/erythema
pain
edema
warm to touch
increased calf circumference

42
Q

what are 2 ways to prevent pressure ulcers? (fill in the blank/written)

A
  • turn the patient every two hours, maintain hydration, keep skin dry, float the heels
  • alternating a lateral position between the right and left side is best for those at high risk for skin breakdown (HOB less than 30 degrees so it doesnt create additional pressure on the coccyx or other bony prominences)
  • diet rich in protein and vitamin c
  • passive range of motion exercises
  • therapeutic mattress
  • do not place client in high fowlers
43
Q

when using a wheelchair, what do you make sure you do before a patient gets in or out of it?

A

lock the wheels

Q

What is the movement called when you lift up the arm/shoulder?

oatmeal
beans
veggies
- not white rice, not waffles, not rice like cereal

50
Q

what can you do to reduce compression of the leg veins?

A

should not place pillow under the knees
- you should also not cross legs, sit for long periods, wear restrictive clothing on the lower extremities, or massage legs
- you should instead, teach client techniques to promote venous return

51
Q

what is involved in active ROM?

A

completing the full ROM of joints and is performed by the client independently such as foot circles, ankle pumps, and knee flexion

52
Q

causes skeletal muscle contractions which promote blood return

A

ROM Exercises

client supine with head of bed elevated 45 - 60 degrees
allows for better ventilation
