```
70
diabetes diet
complete diet just stay consistent. carb counting. take in account weight meds activity level and other health issues
71
diabetes exercise
exercise lowers blood sugar and decreases insulin resistance and glucose intolerance. adjust diet when exercising. need a snack before exercising to prevent hypoglycemia. DO NOT WORK OUT IF BLOOD SUGAR >250 AND KETONES IN URINE! exercise same time each day when glucose is peaking (NOT WHEN INSULIN IS PEAKING). do not inject insulin in area of body that will be exercised. CHECK BLOOD SUGAR BEFORE DURING AND AFTER!
72
only IV insulin
regular and short (lispro aspart glulisine)
73
dawn phenomenon
hyperglycemia when waking. need to increase pts insulin dose or change the timing of the dose
74
somogyi phenomenon
elevated blood sugar at bedtime. hypoglycemia around 2-3 am and rebound hyperglycemia when waking. pts complain of early morning headache night sweats and nightmares. need to decrease insulin does and increase bedtime
75
insulin pumps
continous subcutaneus insulin infusion worn on belt or pocket. change needle q 2-3 days. continous basal rate and the pt can give a bolus. rapid acting and regular short acting insulin only.
76
self monitoring blood sugar
finger prick. alternate sites. wash hands before and after. calibrate monitor. check expiration date on strips.
77
diabetes urine testing.
not reliable for blood sugar levels. used to check for ketones.
78
hypoglycemia
blood sugar less than 70 caused by too much insulin too little food or too much exercise. if patient is hypoglycemic but does NOT have recommended emergency foods give anything.
79

80
hypoglycemia priority nursing actions
check blood sugar.
give 15g simple carb (juice or glucose gel)
recheck blood sugar in 15 mins
give another 15 g simple carb if <70 (can repeat three times)
recheck then give 50% dextrose IV or glucagon subq/IM
when pt recovers have pt eat a snack (carb and protein)
document
**DO NOT GIVE ANYTHING ORALLY IF THE PATIENT IS UNCONSCIOUS OR UNABLE TO SWALLOW. IT INCREASED RISK OF ASPIRATION. INJECT GLUCAGON OR GIVE IV 50% DEXTROSE
81

*CHECK FOR IICP. IF BLOOD SUGAR FALLS TOO FAST BEFORE BRAIN HAS TIME TO EQUAL OUT, WATER IS PULLED FROM BLOOD TO CSF AND BRAIN CAUSING CEREBRAL EDEMA AND IICP
