it Interacts with contrast material used in CT's with contrast and other procedures and can cause acute kidney injury. Needs to be held after pt has a CT with contrast. (1-2 days before and 48 hours after)
67
Basal-bolus regimen
*To mimic the pancreas, provides enough insulin to ensure a steady glucose supply to maintain basic metabolic processes in the body
68
Mealtime insulin
*to provide additional insulin for glucose absorption after meals
69

intermediate acting insulin (NPH) is the only insulin that is
cloudy
75
How do you mix insulin?
clear before cloudy
76

83
when exercising what should BG levels be
between 80 and 250 if exercising
84
Somogyi effect
*Rebound effect in which an overdose of insulin causes HYPOGLYCEMIA, then the release of counterregulatory hormones causes REBOUND HYPERGLYCEMIA
85
Somogyi effect vs. Dawn phenomenon
Both cause hyperglycemia in the morning in Diabetics somogyi: pancreas/liver release glucose; rebound from too much insulin Dawn phenomenon: Release of Growth hormone, coritsol (patient may be stressed)
86
what interventions can be used for Somogyi effects
A bedtime snack, a reduction in the dose of insulin, or both can help to prevent the Somogyi effect.

how do you determine if morning hyperglycemia is caused by the somogyi effect
checking blood glucose levels between 2:00 AM and 4:00 AM for hypoglycemia
88
dawn phenomemon
*Morning hyperglycemia present on awakening *May be due to release of counterregulatory hormones (Growth hormone and cortisol) in predawn hours
89
what interventions can be used for dawn phenomemon
Dawn phenomenon is an increase in insulin or an adjustment in administration time.
90
what patient teaching is needed for diabetic foot care

91
Sick Day Management for Diabetics: S
Sugar: Check your blood glucose every 2 to 3 hours or as necessary
92
Sick Day Management for Diabetics: I
Insulin: Always take your insulin! Not taking it could lead to DKA!
93
Sick Day Management for Diabetics: C
Carbs: Drink lots of fluids! If sugars are high drink sugar-free liquids. If sugars are low drink carb-containing drinks
94
Sick Day Management for Diabetics: K
Ketones: Check your urine or blood ketones every 4 hours. Take rapid-acting insulin if ketones are present.

96
not managing an illness properly when diabetic can lead to
DKA or HHS (Hyperglycemic Hyperosmolar State)
97
Alcohol and diabetes
alcohol lowers blood sugar (puts patient at risk for hypoglycemia) TEACH PATIENT to eat something, mix with a carb containing drink, or nt to drink at all
98
when are glucagon and dextose given
if BG is <20 or patient is unconscious
99
what are ways to tell if ketones are present?
urine, but also if the patient has abdominal discomfort
100
if the client is in ketosis, what are they at risk for
metabolic acidosis
101
how should diabetics wash their feet
clean with a rag BUT HAVE TO DRY!! do not leave anything wet (even with lotion) -no epsom salt -test water temp w sensation feeling part of the body

105
Long acting insulin
glargine (Lantus) detemir (Levemir)
106
What does post-prandial glucose mean and why is it important?
Post-prandial glucose is the glucose level (plasma glucose) after eating. It is important because it tell you how your body responds to sugar after eating, it tells if insulin is being secreted.
