Body is under more stress, need to check sugar more often, more prone to DKA, HHNS, may not eat or drink normal

Q

Oral glucose tolerance test (OGTT)

A

Common for gestational diabetes; fasting glucose is drawn prior, client consumes oral glucose, glucose levels are obtained q30 minutes for 2 hours; diabetes indicated by over 200 after 2 hours (should be under 110 at 30 minutes, under 180 at 1 hour, under 140 at 2 hours)

17
Q

Pre-diabetic

A

Impaired glucose tolerance, impaired fasting-glucose, or both

18
Q

DM

A

Metabolic disorder characterized by increased blood sugar and a problem with insulin secretion, insulin action, or both

19
Q

Diagnostics for pre-diabetic patient

A

A1C 5.7-6.4%, fasting BS 100-125, OGTT 2h BS 140-199

20
Q

Nursing education for pre-diabetic patients

A

Teach lifestyle mods, close monitoring of BS and A1C, watch sx (fatigue, frequently sick), diet, want to wait on oral meds but start low and gradually increase based on A1C and fasting glucose

21
Q

What happens to diabetic meds in the hospital?

A

Often are stopped taking bc want to just use insulin bc can monitor BS more closely

22
Q

When DM pt is sick

A

Tell HCP, watch BS more often, keep taking meds, drink fluids, meet carb needs (Gatorade/Pedialyte)

23
Q

When should diabetics call HCP?

A

Urine ketones, BS over 250, fever over 101.5 and Tylenol not working, ill longer than 2 days, can’t tolerate liquids, persistent N/V/D, confused, disoriented, breathing fast

24
Q

What does the frequency of BS checks depend on?

A

Glycemic goals, T1 or T2, meds, access to supplies, willingness to

25
Q

Self-monitoring BS is…

A

CRITICAL

26
Q

How is insulin given on a regular basis?

A

Basal-bolus regimen; long-acting basal (glargine) insulin at bedtime and rapid/short-acting (lispro/human regular) before each meal

27
Q

Insulin is a high alert med

A

ALWAYS check current level and ALWAYS check diet order and pt oral intake tolerance before giving

28
Q

Hypoglycemia

A

BS below 70 (may have sx above 70)

29
Q

Hypoglycemia sx

A

Sweaty, blurry vision, dizzy, anxiety, hunger, irritable, shaky, fast heart rate , headache, weak, fatigue

30
Q

Tx for hypoglycemia

A

Rule of 15 (if can swallow)—15g single carbs (ie 4oz juice, 3 glucose tabs, avoiding sugar with fat, BS will increase 50 mg/dL); check BS after 15 minutes then eat normal meal or give carbs again if still low; IM glucagon or IV D50 (25-50 mL)

31
Q

Hyperglycemia

A

Caused by illness, infection, self-management problems, stress; can lead to a crisis situation of diabetic ketoacidosis (DKA) or HHNS

32
Q

Hyperglycemia symptoms

A

Weakness, fatigue, blurred vision, headache, N/V/D

33
Q

Hyperglycemia tx

A

Check for urine ketones, insulin, drink fluids, education and prevention

34
Q

Insulin pump s

A

Usually rapid acting or regular; continuous release of SQ basal infusion; can be increased or decreased, can get bolus based on FSBG; pt required to check BS 4x/day; often deactivated in hospital and switch to sliding scale

35
Q

Problems with insulin pumps

A

Infection at insertion site, increased risk of DKA if pump malfunctions, cost (not always covered)

36
Q

Macrovascular disease and nursing implications

A

Inc risk of CVD with diabetes; educate, stop smoking, control BP, diet mods

37
Q

Microvascular disease and nursing implications

A

Retinopathy, neuropathy, nephronopathy; frequent eye exams, increased risk of damage to lower extremities—ulcers and amputations; loss of protective sensation (LOPS)—don’t know injury occurred; check feet or have others check

38
Q

Diabetic foot care

A

Wash with soap and water, inspect and pat dry, apply lanolin to feet and mild powder to sweaty toes, clean cuts with soap and water, don’t remove corns or calluses, report nonhealing infections, trim nails after shower and trim across, separate overlapping toes with cotton, wear stable, encompassing shoes and shake before wearing, wear clean, absorbent socks, no hot water bottles

39
Q

Nutrition for diabetes

A

High fiber, low fat, low cholesterol; encourage complex carbs and limit simple carbs; diet low in saturated and trans fat; fibrous foods like beans, veg, oats, whole grains; protein—meat, eggs, fish, nuts, beans; 1 daily alc for women and 2 for men

40
Q

Exercise for diabetics

A

Proper footwear; exercise after meals and check sugar every 30 minutes if vigorously exercising; don’t exercise under 80 or above 250; eat a carb if planning to exercise hard and carry carb snack with you; wear medical alert bracelet

41
Q

Nursing for hospitalized diabetics

A

Stress/surg can increase BP (often becomes uncontrolled); impaired wound healing, high risk of infection

42
Q

Integumentary concerns for diabetes

A

Diabetic dermopathy—reddish brown spots on skin; acanthosis nigricans—brown/black thickened skin in folds; necrobiosis lipoidica diabetics rum—red patch around BVs
