32
List the 4 steps of the digestion process.
1. Digestion: Begins in the mouth and ends in the small and large intestines
2. Absorption: Intestine is the primary area of absorption
3. Metabolism and storage of nutrients
4. Elimination: Chyme is moved through peristalsis and is changed into feces
33
What are the three parts of the small intestine (in order)?
Duodenum, jejunum, and ileum
34
What is absorbed by the small intestine?
Carbohydrates, protein, minerals, and water-soluble vitamins
35
What is peristalsis?
A series of involuntary wave like muscle contractions which move food along the digestive tract
36

Ileum/small intestine
37
Where is a colostomy located?
Colon/large intestine
38

What is the difference between impaction and constipation?
A person is unable to relieve the impaction on their own
44
What do you need to assess before performing the digital removal of stool?
Heart rate
45
What do different wound colors indicate?
Beefy Red – indicates tissue and skin healing, appropriate blood supply
Pink – no active s/s of infection, blood supply isn’t ideal
Yellow – slough or infection (Slough is the consistency of snot, indicates body ridding itself of bad tissue)
Black – dead tissue, no blood supply

2. After positioning the patient on the bedpan, elevate the head of the bed to a 45-degree angle.
3. Adjust the head of the bed so that it is lower than the feet, and use gentle but firm pressure to push the bedpan under the patient.
4. Have the patient stand beside the bed, and then have him or her sit on the bedpan on the edge of the bed.
5. Make sure the patient has a nurse call system in reach to notify the nurse when he or she is ready to have the bedpan removed.

70
What causes pressure injuries?
Unrelieved prolonged pressure
Localized damage to the skin and underlying soft tissue
Can be intact, a blister, or open ulcer.
71
Patients at risk for pressure injuries?
Decreased mobility
Decreased sensory perception (quad/paraplegic)
Incontinence
Poor nutrition
72
Pathogenesis of pressure injury?
Pressure applied over period of time causes a capillary to occlude and causes tissue ischemia
If blood flow returns area is erythematic in color due to vasodilation.
73
How to assess a pressure injury?
Press a finger to the area:
If it turns lighter in color and erythema returns this is blanchable
If it doesn’t change color this is called non-blanchable. If this occurs deep pressure injury is probable
