A
  • make you retain sodium and water

- make you lose potassium

35
Q

TOO much aldosterone?

not enough aldosterone?

A

too much- fluid volume excess, serum potassium DOWN

not enough- fluid volume deficit, serum potassium UP

36
Q

____ are made in the pituitary and they stimulate cortisol to be made.

____ is a hormone of the adrenal cortex.

A 
adrenocorticotropin hormone (ACTH)
cortisol
37
Q

___ACTH= ____ cortisol level.

too many steroids= _____

A

UP,UP

hypercortisolism

38
Q

adrenal cortex problems:

not enough steriod—___–____.

A

shock

high potassium

39
Q

addisons disease:

A

they do not have enough glucocorticoids, mineralcorticoids, or sex hormones.

-normally, aldosterone makes us retain sodium and water and lose potassium….now we dont have enough (insufficient), so will lose sodium and water and retain potassium.
now the serum potassium will be UP.

40
Q

s/s of addisons disease:

A
  • initially, the majority of s/s are a result of the hyperkalemia.
  • begins with muscle twitching and then proceeds to weakness, followed by flaccid paralysis
  • anorexia/nausea
  • hyperpigmentation- bronzing color of the skin and mucous membrane
  • decreased bowel sounds
  • GI upset
  • white patchy area of depigmented skin (vitiligo)
  • hypotension
  • decrease NA, increased potassium and hypoglycemia
41
Q

treatment for addisons disease:

A
  • combat shock (losing sodium and water)
  • increase sodium in their diet
  • processed fruit juice/broth (has lots of sodium)
  • I&O and daily weight
  • if this client is losing sodium and water, their BP will probably be LOw
  • losing weight
  • fluid volume defict
  • willbe placed on mineralcorticoid drug flurocortisone. its aldosterone
  • daily weight
42
Q

acute weight gain think ____ FIRST

A

heart problems and pulmonary edema

43
Q

addisonian crisis = ______

A

severe hypotension and vascular collapse

44

-increased risk for infection
-hyperglycemia
-psychosis to depression
-moon faced
-truncal obesity
-buffalo hump
(all these are TOO many gluco)
-oily skin
-women with male traits
-poor sex drive 
(all these are TOO many sex drive)
-high bp
-chf
-weight gain
-fluid volume excress
(these all are tOO many mineral)
45
Q

if you did a 24 urine on the cushing’s client the cortisol level would be ____.

since the client has too many mineralcorticoids (aldasterone), the serum potassium will be ___.

A

UP

DOWN

46
Q

treatment for cushing’s

A
  • adrenalectomy (unilateral or bilateral)
  • if both removed—lifetime replacement
  • quiet enviroment
  • avoid infection
  • diet: increase K, decrease NA, increase Protein, Increase CA
  • glucose and ketone in their urine
47
Q

steroid ____ serum calcium by excreting it through the ___.

A

decrease

GI tract

48
Q

normal lab values of blood glucose

A

70-110

49
Q

diabetes type 1:

A

  • usually diagnosed in childhood
  • causes: auto-immune response (type 1a) or idiopathic (type 1b)
  • first sign may be DKA
  • appears abruptly, despite years of beta cell destruction
50
Q

diabetes type 1:
you have to have ___ to carry glucose our of the vascular space into the cell…. since there is no insulin, the glucose just builds up in the ____ space, the blood become hypertonic and pulls fluid into the vascular space… the kidneys filter excess glucose and fluid (polyuria and polydipsia) the cell are straving so they start breaking down protein and fat for energy (polyphagia)…when you break down fat you get ___ (acids)… now this client is ___.

A

insulin
vascular
ketones
metabolic

51
Q

diabetes type 1 :

s/s an treatment

A

-polyuria,polydipsia, polyphagia

  • oral hyperglycemic med will NOT work for this pt.
  • they have to have insulin!!
52
Q

hyperglycemia=____

A

3ps

polyuria,polydipsia,polyphagia

53
Q

type 2 diabetes:

  • these clients dont have enough ____, or the insulin they have is no good
  • these clients are usually ___.
  • they cant make enough insulin to keep up with the ____ load the client is takin in .

55
Q

treatment for diabetes type 2-

A

start with diet and exercise and then add oral agents. some clients may have to take insulin

56
Q

gestational diabetes:

Q

complication to baby if mom has gestational diabetes:

A

increased birth weight

hypoglycemia

58
Q

extreme blood sugar =___

A

vascular damage

59
Q

diet for diabetes:

A
  • majority of calories should come from : complex carbs, then fats and lastly protein (limit protein to 10-20%, why? tend to have renal disease, cant handle protein)
  • sugar destroys vessels just like fat; CAD
  • high fiber diet (keep blood sugar steady)[high fiber slows down glucose absor[tion i the intestines, therefore,eliminating the sharp rise/fall in blood sugar.
60
Q

exercise for diabetes:

A
  • wait until blood sugar normalize to begin exercise
  • eat before to prevent hypoglycemia
  • exercise when blood sugar is the highest
  • exercise same time and amount daily
61
Q

how do oral hypoglycemic agents work?

who do you give this to?

A

stimulate the pancreas to make insulin!

(best nclex answer! despite whether they stimulate pancreas, all oral hypoglycemic work to decrease the amount of circulating glucose.)

type 2 only!

62
Q

how is the insulin dose determined?

A

it is based on body weight. the average adult dose of insulin is 0.4-1.0. the insulin dose is adjusted until te blood sugar is normal and until there is no more glucose or ketone in the urine.

63
Q

Reg insulin is ___…NPH is ____

A

clear

cloudy

64
Q

IV

65

67
Q

A

once a day

divided

68
Q

snack are ___ required with basal/bolus insulin dosing, but clients still must eat when dosing with rapid-acting insulin. so have food available.

A

NOT

peak

lowest

69
Q

when drawing up regular and NPH insulin together, which one do you draw up first?

A

regular! (clear to cloudy!)

70
