If your patient is taking a combination drug (Diuretic and Beta blocker) which intervention should the nurse implement?

instruct the patient to sit on the side of the bed before getting out of the bed

38
New cards

because Digoxin is a cardiac glycoside, what effects does it have on the heart?

  • it increases contractility and decreases HR

  • positive inotropic

  • negative chronotropic

  • makes the heart a more effective pump

39
New cards

how will you know that Digoxin therapy is working?

because the patient will be able to tolerate walking and preform ADLs without getting tired

40
New cards

how do ACE inhibitors work?

by blocking the conversion of Angiotensin 1 to Angiotensin 2

41
New cards

Angiotensin 2

is an extreme potent vasoconstrictor, thus by blocking Angiotensin 2 conversion, ACE inhibitors block vasoconstrictions from taking place leading to vasodilation and decreasing BP

42
New cards

  • used for controlling hypertension

  • used to decrease mortality from M.I.

  • used to delay the progression of diabetic neuropathy

  • the first line therapy for HF

45
New cards

Nitrates can lead to a patient developing

reflex tachycardia

51
New cards

Nitrates do NOT

have effect on increase of myocardial contraction, so it does not cause bradycardia

52
New cards

Nitrates will

58
New cards

type 2 diabetes is

what is HgbA1C level used for

to check on diabetic management

61

it increases the BS level in the body (tx for hypoglycemia)

62
New cards

s/s of hypoglycemia

  • shaking

63
New cards

what is diabetic ketoacidosis

when the body cannot utilize the sugar due to lack of insulin production and it switches to fat as metabolism, thus producing ketones and turning the ph. acidic

  • humalog Lispro

  • Regular insulin

65
New cards

what insulin is the only type that can be infused IV?

regular

66
New cards

how are all other insulins (Lantus, NPH) administered?

subcutaneously (SQ)

67
New cards

If patient takes regular insulin at 0700, what meal will prevent patient from going Hypoglycemic?

breakfast (30 min onset)

68
New cards

If patient takes 25 units of NPH insulin to a client with DM Type I at 1600. Nurse should ensure that

the client eats a snack at bedtime because this insulin has a peak of 4-12 hrs; this means that starting at 8 PM through 4 AM the patient is at risk for hypoglycemia which is why they need a snack at bedtime

69
New cards

decreasing hepatic production of glucose from stored glycogen.

70

order for drawing insulin

cloudy clear clear cloudy

71

temperature

74
New cards

what is a sign that antibiotic therapy is effective

if a patient starts complaining of itchiness and SOB while receiving antibiotics IV

discontinue IV

86
New cards

multi-drug therapy is usually not recommended except if the patient has

90
New cards

if a patient comes to the hospital with symptoms of an infection what should be drawn before starting antibiotics?

ALL cultures

91
New cards

why should glucocorticoid drugs like prednisone need to be tapered down slowly?

Adrenal collapse / adrenal gland atrophies as we start with synthetic glucocorticoids. Thus, if patient stops medication abruptly the adrenal glands will not be able to re-start hormonal production that fast and collapse will take place

92
New cards

what should the nurse suggest to the patient while taking glucocorticoids

stay away from large crowds because glucocorticoids decrease one’s immune system

93
New cards

what labs should be monitored for patients taking glucocorticoids IVP

blood glucose levels

94
New cards

Disorders of the adrenal gland can be differentiated by

under production of the adrenal hormones or overproduction of the same hormones
