C.O. contractility - Cardiomegaly, pericardial effusion - Bradycardia - Dec. GI motility - Constipation and distension - Hypercholesterolemia - Periorbital edema - Treatment - **Levothyroxine** - Patient Education - Take in the morning, before breakfast. Answer: Ask them when they take it - Low to high dose - Taken for life. - Do not take for weight loss. - S/sx of too much- increased HR and hot flashes - Expected outcomes. - Weight loss, improved tolerance to environmental temperature, increased activity and increased pulse rate. - Black box warning - Use of thyroid hormone in treatment of obesity or weight loss is contraindicated. - Evaluate effectiveness. - Normal T4 and TSH **Corticosteroids (hydrocortisone)** - Therapeutic Uses - Addison's disease, inflammation, immune suppression - Asthma, allergies, cancers, COPD, gout, IBD - Patient Education - Must always be tapered, usually no longer than 2 weeks - Take at the same time with food. - Take as ordered, not when symptoms present - Adverse/Side effects - Immunosuppression, hyperglycemia, osteoporosis, fractures, peptic ulcers, clots, HTN - Long term effects- moon face and weight gain Steroid- -

Therapeutic use - Cushing's disease- causes elevated BP - Too much ACTH **Octreotide** - Therapeutic use - Acromegaly - Too much GH **Cosyntropin** - Therapeutic use - Treat adrenocortical insufficiency - Resembles ACT and used to diagnose cause of insufficiency - Addison's disease- most common cause is stopping corticosteroids without tapering - Too little ACTH Negative feedback- mechanism by which the body indicates it no longer needs a specific stimulus **[Diabetes Insipidus]** - Manifestations of DI - Polyuria - Polydipsia - Treatment - Desmopressin (DDAVP)- Given for DI - How to administer SQ steps - Prepare injection as instructed - Wash site with soap and water or alcohol wipe -

Adverse effects - Water intoxication- manage fluid status: drowsiness, HA, listlessness, coma - Nausea, abdominal pain/cramping, HTN - Evaluate effectiveness. - Monitor BP, NA and decreased urine output. - Monitor BP and fluid intake **[Diabetes Mellitus]** - Functions of the pancreas - When glucose levels are high, the blood stimulates the release of insulin from the pancreas, which functions as a control center. - Patho for type 1 and type 2 - Type 1- insulin dependent - Type 2- insulin resistance - Role of glucagon, glucose, and insulin - Glucagon- stored glucose that acts to increase blood glucose levels. - Glucose- the body's primary energy source - Insulin- acts to decrease blood glucose levels. - Evaluating diagnostic tests - Normal glucose- 70-110 - Hypoglycemia \126 indicates diabetes. - Hemoglobin A1C \> 6.5% indicates diabetes. - Glucose over the last 6-12 weeks - DM patients want \ - Hyperglycemia - Signs/symptoms - Polyuria - glucosuria - Elevated BS - Treatment - Insulin - Hypoglycemia- deadly, more dangerous than hyperglycemia - Signs/symptoms - Tremors - Clammy - Confusion - Slurred speech - Treatments - Juice/crackers if can swallow - IV dextrose- NPO - IM glucagon- No IV - **[Type 1]** - Insulin dosing schedule - Do NOT double doses. - Sliding scale interpretation - The amount of insulin needed to take depending on how high the patient's blood glucose is. - Complication of injections and prevention - Lipohypertrophy - Rotate injection sites. - **Insulin** - Patient teaching - Assess blood glucose prior to administration. - Use only insulin syringes. - Rotate sites to prevent lipohypertrophy. - Do not massage. - Clear to cloudy when mixing insulins. - Short acting before NPH - Roll NPH, do not shake. - Refrigerate unopened insulin. - Once opened, good for 30 days - Signs of hypoglycemia - Medical alert bracelet - Route of administration - Subcutaneous- Insulin cannot be given PO - Regular insulin is the only insulin that can be given IV. - Adverse effects/side effects - Hypoglycemia - Hypokalemia - Mixing regular and NPH - Rotate vial in hands - Disinfect tops of both vials - Inject air into isophane (NPH) vial -
