Long term complications of diabetes
Vascular changes as early as 2 1/2 to 3 years after diagnosis if poor diabetic control. Intensive insulin therapy delays the onset: Retinopathy, nephropathy, neuropathy.
Why do those with diabetic ketoacidosis experience kussmaul respirations?
When the accumulated ketones exceed the body's capacity to extract them, they overflow into urine (ie, ketonuria). If the situation is not treated promptly, a greater accumulation of organic acids leads to frank clinical metabolic acidosis (ie, ketoacidosis), with a significant drop in pH and bicarbonate [4] serum levels. Respiratory compensation for this acidotic condition results in Kussmaul respirations, ie, rapid, shallow breathing (sigh breathing) that, as the acidosis grows more severe, becomes slower, deeper, and labored (air hunger).
Define precocious puberty
girls less than 8 yo or boys less than 9 yo
Cushing syndrome
Adrenal Cortex - excess (hyper) Excessive circulating free cortisol Uncommon in children. Children with Cushingoid Appearance Caused by excessive or prolonged steroid therapy Reversible once steroids are gradually discontinued "Moon face"
Hypopituitarism - Anterior
Failure of growth hormone (GH) and subsequent failure of secretion of other hormones. Consequences depend on degree of dysfunction.
Issues surrounding growth hormone replacement
Family education related to daily subcutaneous injections. Timing best at bedtime. Need psychological support so child raised normal for age not appearance (Huge Issue) Joint decision on when to stop GH therapy. Epiphyseal closure is a criterion for ending therapy.
Diabetic ketoacidosis: what does the patient look like?
Fatigued, weight loss, nausea and vomiting, thirsty (very dry mouth), drowsiness, rapid breathing, etc.
Hyperthyroidism diagnosis
Increased levels of T4 and T3 TSH is low or undetectable.
Fluid replacement treatment
Initially 0.9% saline solution. Replace deficit at an even rate over 36 to 48 hours Maintenance rate + Fluids needed to replace loss. Need to be careful not to replace too quickly or else cerebral edema may occur.
Which system compensates during diabetic ketoacidosis?
Metabolic acidosis
Treatment of type 1 diabetes
Monitoring: Blood Glucose - 4 times a day. Hemoglobin A1C - every 4 months. Urine Testing - No longer recommended. Nutrition: Snacks. Frequent Meals Exercise: Will lower blood sugar levels.
Hypoglycemia
Most common before meals or when insulin effects are peaking. Triggers include: Vigorous exertion, Gastroenteritis, Error in insulin administration.
Insulin pump requirements
Must check blood glucose at least 4 times/day Be willing to make adjustments in insulin, exercise and food in response to results of tests

Adequate insulin for ketoacidosis
No insulin administration until blood glucose and urine ketones is obtained. Continuous insluin at a dosage of 0.1 units/kg/hr. Goal is to decrease blood glucose levels by 50 to 100 mg/dl/hr. Once below 250 to 300 mg/dl, add dextrose to IV solution. Want blood sugar between 120 to 240 mg/dl.

Onset - abrupt Might be triggered by diet, virus Presenting symptoms: 3 P'- Polyuria, Polyphagia, Polydypsia. Symptoms also include weight loss and lethargy over a few days or weeks.
Hypopituitarism -Anterior - Excess Growth
Overgrowth of long bones - Height 8 feet or more. Excess growth hormone before epiphyseal closure. Acromegaly or gigantism. Excess growth hormone after epiphyseal closure - resulting in widening of bones (transverse).

The pre-meal insulin dose adjustment based upon the pre-meal blood sugar. Usually determined by a Dietician or Diabetes Educator.
Treatment of hypoglycemia
1. Check blood glucose level. 2. If below 70 mg/dL give 10 to 15 g of simple carbohydrate. 3. Recheck blood sugar in 15 minutes 4. If still below 70, give another 10 to 15 g of simple carbohydrate 5. Recheck again in 15 minutes. 6. Once above 80 mg/dL, give a more substantial snack: complex carbohydrate and protein. Ex: Crackers and peanut butter.

Carb counting insulin therapy
Treated with Lantus and Novolog/Humalog Insulin Lantus may not be mixed with any other insulins and you do not hold based on blood sugar. Dietary Considerations: Allow patient 45 minutes maximum to finish food. Food items do not need to be replaced if not eaten. When patient finished eating, count the number of carbs eaten. Nursing Considerations: Check blood sugar, give food tray, count carbs eaten, call doctor with blood sugar level and carbs eaten to receive insulin dose, then give insulin.
Traditional insulin therapy
Treated with Novolin/Humulin NPH and Novolog/Humalog Insulin Dietary Considerations: Patient needs to eat meal with in 15 minutes of receiving insulin. Allow patient 45 minutes maximum to finish food. Exchanges: A carbohydrate exchange equals 15 carbs. Patient must eat every carb counting food on the tray. If patient does not want a certain carb item, it must be exchanged for something of equal carb value. Nursing Considerations: Check blood sugar, call doctor with blood sugar level, receive insulin dose order, give insulin, give food tray immediately.
Treatment for excess growth
Tumor - Surgery Other: External radiation and radioactive Implants Hormone Replacement: Thyroid, cortisone, sex hormones If no tumor, can retard further growth. Cannot reduce growth already achieved.

Units of insulin needed to "cover" grams of carbohydrate consumed. Usually expressed as units insulin:grams of carbohydrates○ e.g., 1:10 = 10; 3:12 = 4
Treatment for congenital adrenal hyperplasia
Untreated: Early Sexual Maturation Confirm diagnosis and Assign a Sex, Usually according to genotype Female - Diagnosed at Birth: Treat with cortisone. Signs and symptoms in female gradually disappear, and excessive early linear growth is slowed. Fertility depends on degree of deficiency and compliance with therapy. Male: Typically no signs and symptoms. Diagnosed when puberty begun early. If testicular masses - infertile Female - Raised Male - Diagnosed when virilism appears. Continue raising child as male. Hormone replacement to permit linear growth and initiate male pubertal changes. Surgery to remove female organs and reconstruct the phallus - infertile.
