Q

Sleep deprivation
causes…

A

IRRITABILITY AND
MOODINESS
APATHY IMPAIRED
MEMORY
POOR
JUDGEMENT
HALLUCINATIONS
CAN DEVELOP

45
Q

in the exhaustion stage Body can no longer achieve homeostasis which leads to

A

Hypertrophy of adrenal cortex
* Atrophy of lymphatic tissue
* Bleeding ulcers

46
Q

Immunosuppression from
cortisol leads to

A
  • Decreased response of
    WBCs
  • Atrophy of thymus and
    decreased T-cells
47
Q

Allostatic Load

A

chronic stress
* Long term dysregulation

48
Q

Allostatic overload

A
  • Exhaustion
  • Stress-induced disease or
    disorder
49
Q

overload can cause

A
  • Hair loss
  • Tension
  • Mouth sores
  • Asthma
  • Palpitations
  • Tics
  • Digestive disorders
  • Irritable bladder
  • Acne
  • Irregular periods
  • Impotence
  • Sleep disturbances
50
Q

Over production of Stress hormones
leads to

A

-Effects memory Major depressive disorders
-Immunosuppression
Increased risk of infection
Autoimmune disorders
Decreased healing
Prolongation of existing infections

51
Q

What is considered the primary stress hormone?

A

Cortisol

52
Q

Cortisol (increases/decreases) the amount of glucose in the body

A

increases

53
Q

If glycogen increases, does glucose increase or decrease?

A

decrease

Glucose levels decrease: As glucose is converted into glycogen for storage, circulating glucose levels in the blood decrease.

62
Q

Protein Metabolism and Fat redistribution are linked to this hormone…

A

cortisol

63
Q

What happens to the cardiovascular system when there is an adrenal insufficiency with glucocorticoids (Cortisol)?

A

64
Q

Q

Hyponatremia is a decrease in…

A

Na

68
Q

T/F: renal failure can occur with decreased aldosterone and adrenal insufficience of mineralcorticoids

A

t

69
Q

T/F: ACUTE adrenal insufficiency is a medical emergency

A

t

70
Q

What occurs when you abruptly take someone off steroids?

A

adrenal failure, decreased cortisol (adrenal gland needs time to adjust and start making its own cortisol)

71
Q

A patient comes in who abruptly stopped taking their steroids. They are experiencing hypotension, dehydration, weakness, and have nausea. How will you cure this patient?

A

fluid replacement (increase volume), increase glucose, administer steroids

72
Q

T/F: Steroids do NOT have anti-inflammatory properties

A

f

73
Q

With increased stress, you can (increase/keep) the dose of steroids. when stress passes you should..

A

increase

titrate it down to normal dose

74
Q

With what situations do we give steroids for?

A

allergies, asthma, COPD, inflammatory bowel disease, lupus, edema, post-transplant

75
Q

steriods can be adminstered in cases of

A

Excessive or extreme stress
* Trauma
* Sepsis
