Q

Identify the normal defenses of the body against infection

A

Skin — 1st line of defense, shedding outer layer of skin cells, sebum; mechanical barrier to microorganisms + antibacterial activity
Mouth — multilayered mucosa, saliva
Eyes — tearing, blinking
Respiratory tract — cilia lining upper airways, coated by mucus, macrophages
Urinary tract — flushing action of urine flow, intact multilayered epithelium
GI tract — acidity of gastric secretions, rapid peristalsis in small intestine
Vagina — @ puberty normal flora cause vaginal secretions to achieve low pH

Q

Discuss the development of the inflammatory response

A

Purpose of inflammation: protective vascular rxn involving cascade of physiological responses to neutralize and eliminate pathogens/necrotic tissues, establishes a means of repairing body cells and tissues

1) Redness
2) Warmth
3) Pain
4) WBC count increases
5) Fever
Exudate: purulent drainage; serous or sanguineous exudates
Tissue repair: tissue defects heal and close
Immune response: when a foreign material (antigen) enters the body, a series of responses changes the biological makeup of the body; the next time the same antigen enters, antibodies bind to the antigens, neutralize, destroy, and eliminate

Exam Concepts

A

What to/not to do?

— Problems with prolonged immunity
— Sources of protein/ nutritional servings per day
— Fall risk assessment
— Isometric exercises
— Cane ambulating
— Agitated client safety
— Hand hygiene
— Ergonomics in lifting
— Biohazard
— Crutch gait
— WBC labs
— PPE donning/doffing
— MRSA transmission
— W/C safety
— TB
— Fall
— Fires
— Restraints

55
Q

Problems with prolonged immunity

A

Develop resistant tendencies?
because of hyperactive immune responses your body can’t tell the difference between your healthy, normal cells and invaders. In essence, your immune system turns against you.

56
Q

Nutrient-dense sources of protein

A

— Red meat
— Cream soups/meat-based vegetable soups
— Cheese, eggs, peanut butter
— Milk/fortified milk-substitutes w/ Ca + VitD (soy, almond, rice)

57
Q

— WBC labs —
Ranking WBC differential counts from largest to smallest percentage found in your body

A

WBC — 5,000-10,000/mm3 — increased = acute infxn
Neutrophils — 55%-70% — acute infxn
Lymphocytes — 20%-40% — bacterial/viral infections
Monocytes — 2%-8% — protozoan, rickettsial, TB infections
Eosinophils — 1%-4% — parasitic infection
”Ew, there’s something inside of me”
Basophils — 0.5%-1% — allergic rxns

_N_ever
_L_et
_M_onkeys
_E_at
_B_ananas

NOTE: Bone marrow not waiting for the baby neutrophils to mature, so sending them out to fight the infx = VERY SICK = bandemia/left-shift

58
Q

Isometric exercises

A

Involve tightening or tensing muscles with­out moving body parts (isometric contraction)
e.g. holding a bicep curl, wall squat

Why? ideal for patients who do not tolerate increased activity

59
Q

Crutch Gait

A

— The basic crutch stance is the tripod position, formed when the crutches are placed 15 cm (6 inches) in front of and 15 cm to the side of each foot

60
Q

What is the chain of infetion?

A

Infectious agent –> Reservoir –> Portal of Exit –> Modes of Transmission –> Portal of Entry –> Susceptible Host

61
Q

Bones perform 5 functions in the body

A

1) Support
2) Protection
3) Movement
4) Mineral storage
5) Hematopoiesis (blood cell formation).

62
Q

Order: 650mg Tylenol PO q4-6hrs
Available: 325mg tablets

A

(650mg/325mg) x quantity —> 2 tablets

63
Q

Practice problem: In 9 hours, what is the intake?

A

30mL = 1oz
240mL = 8oz
_____________
250mL NS
150mL packed RBC
15mL (=30mL)
8oz OJ
4oz jello
NS @ 75mL/h = x9 = 675mL
___________
TOTAL = 1450mL

64
Q

Order: 650mg
Available: 325mg/2mL

A
