Q

Pharmacological nursing Management

A

-Oral medications are started at a low dose and increased gradually based on A1C levels and FBG levels. More frequent in type 2

-Often in hospitalized patients oral medications are stopped and put on insulin while acutely ill. (Able to maintain tight glucose control while on insulin)

-Bring forward patho concepts

Q

What do we do with patients when they have diabetes and are sick?

A

-Steroids (oral/IV) make your blood sugar RISE. (May need to alter insulin regiment at home, adjust basal dosage, increased scheduled doses)

Q

Why is being sick with diabetes a big problem

A

-sickness causes the body stress, may cause your body to release more glucose, so may have to check blood glucose more often, adjust insulin regiments, etc.

-Patients are more prone to go into DKA, HHNS when sick

-If stomach virus, may not be eating or drinking, must check blood sugar more often and treat as necessary. (Still need to take oral medications if sick to your stomach if possible)

-what is the onset of cation of the insulin. Is it rapid acting, short acting, intermediate, long acting

-when does the insulin peak?

-what is the duration of action

Usually deactivate and switched to a sliding scale regimen

53

retinopathies
nephropathies
neuropathies

56

Q

Macrovascular disease: teaching points

A

-education

-stop smoking, control blood pressure, modify high fat diet

58
Q

Nursing Consideration Neuropathy

A

Highest risk = Lower extremities and feet. (Foot ulcerations and lower extremity amputations common complications

Lost of protective sensation (LOPS)

Diabetic Foot Care

A

Know the 13 steps

60
Q

Nutritional Considerations for Diabetes

A

Eat a balanced high fiber, low fat, low cholesterol diet

Carbs = 45-65% of total daily caloric intake. (Limit simple carbs)

Fats = low saturated and trans fat. (polyunsaturated is best = fish)

Fiber = Promote finer intake (Can improve metabolism and lower cholesterol)

Protein = Promote intake from meats, eggs, fish, nuts and beans. (15-20% total intake)

Alcohol: Limit to 1 or 2 drinks

61
Q

Exercise

A

-Important encourage because it can lower blood sugar. Do not exercise if glucose levels are less than 80 or higher than 250 (Best to exercise after meals)

-Wear medical alert bracelet

-If more than 1 hour has passed since eating and high-intensity exercise planned teach to EAT a carbohydrate snack prior

62
Q

Nursing Considerations for Hospitalized Diabetic Patient

A

-Stress/surgery can increase blood glucose levels. Controlled can become uncontrolled in the hospital
