Patho of DM type 1 body’s own T cells attack and destroy pancreatic beta cells, which are the source of the body’s insulin. Autoantibodies to the islet cells cause a reduction of 80%-90% of normal B cell function before hyperglycemia and other manifestations occur.
Patho of DM type 2 Pancreas continues to produce some endogenous insulin. However, the insulin that is produced is either insufficient for the needs of the body and/or is poorly utilized by the tissues.
3 types of Strokes Thrombotic stroke, Embolic Stroke, Hemorrhagic stroke
Thrombotic stroke injury to a blood vessel wall and formation of a blood clot. The lumen fo the blood vessel becomes narrowed and, if it becomes occluded, infarction occurs. (most common)
Embolic Stroke Embolus lodges in and occludes a cerebral artery, resulting in infarction and edema of the area supplied by the involved vessel. (2nd most common)
Hemorrhagic stroke A rupture of a vessel bleeding into the brain tissue itself or into the subarachnoid space or ventricles.
MRI Magnetic resonance imaging is used to determine the extent of brain injury. It uses magnetic energy to detect strokes, MS, tumors, trauma, herniation, and seizures. Not invasive. Contrast may be used.
CT computer assisted x-ray of the body parts are done to detect problems such as hemorrhage, tumor, cyst, edema, infarction, brain atrophy and other abnormalities. Contrast may be used to enhance visualization of the brain structures.
Why would a diabetic have ketones in their urine? Circulating insulin insufficient so glucose cannot be used for energy, body breaks down fat for fuel. Ketones- acidic by-products of fat metabolism causing serious problems when they build up. Ketosis alters pH balance, causing metabolic acidosis.
Embolic stroke S/S rapid occurrence of severe neurologic effects
Hemorrhagic stroke S/S Characterized by sever headache, vomiting, loss of the ability to walk, dysphasia, pysarthria, and eye movement disturbances
Ischemic Stroke S/S LOC unlikely in the 1st 24 hrs. If a lacunar stroke motor hemiplegia, pure stroke sensory, collateral leg and face weakness w/ arm and leg ataxia,

Avoid excessive alcohol intake, fatigue, and loss of sleep.
The patho of a-fib that would render a person at risk for a stroke A- fib can often result in a decrease in CO because of ineffective atrial contractions or loss of atrial kick, and/or a rapid ventricular response. Thrombi may form in the atria as a result of blood stasis.
Atrial fibrillation (A-Fib) Characterized by a total disorganization of atrial electrical activity due to multiple ectopic foci resulting in loss of atrial contraction.

Why does the nurse assess for tetany in a patient who has had his thyroid removed? Tetany-neuromuscular hyper-excitablilty due to low calcium levels (can occur with thyroid or parathyroid surgery).

How does DM lead to blindness? Micro vascular complications cause thickened vessel membranes. Pt’s w/ DM are at increased risk for glaucoma and cataracts. The micro vascular damage can occur to the retina leading to some degree of retinopathy.
Non proliferative Retinopathy most common, partial occlusion of small blood vessels in the retina cause microaneurysms, microaneurysms leak capillary fluid casing retinal edema.
Proliferative Retinopathy most severe, involves both the retina and vitreous, Capillaries become occluded so body produces new blood vessels which are fragile and break. pt sees black or red spots or lines, can cause partial or complete retina detachment.
Multiple sclerosis Disease is chronic, progressive, degenerative, and has exacerbations and remission. Plaques develop on the myelin sheaths.
Multiple sclerosis treatment symptom relief, controlled by drugs including ACTH, methylprednisolone and prednisone to help treat the exacerbations by relieving the edema and inflammation at the site of demyelination. Nutritional therapy for proper diet.
Myasthenia Gravis Disease is characterized by fluctuating weakness of certain skeletal muscles.

Why would a person choose a vaginal hysterectomy over a TAH vaginal hysterectomy used for repair and removal of uterus. The TAH is done to remove large tumors, tubes and ovaries. The vaginal hysterectomy has better recovery. The TAH is more complicated and presents postoperative problems with incision in abd.
6. Explain the (2) most commonly used assessments that nurses use to determine hypocalcemia. Chvostek - contraction of the facial muscle in response to tap over the facial nerve in from of the ear. Trousseau’s sign- a b/p cuff is inflated on arm to above the systolic pressure, within 3 minutes pt will experience a carpal spasm.
Describe pathophysiology of Cushing’s syndrome. The body develops tumor which causes the pituitary to secrete adenocorticotropic hormone (ACTH). This ACTH causes the body to gain weight around the trunk and face and increases gluconeogenesis by the liver.
What is IGT Impaired Glucose Tolerance (borderline diabetes), blood glucose levels above normal but not enough for DX of DM. dx=fasting blood glucose level is >100 but <126 mg/dl. Random plasma glucose measurement or OGTT of >140 but <200 can also be done.
Pathophysiology of Parkinson’s Disease that would reflect the cogwheel rigidity. Disruption in Dopamine and acetylcholine levels causes abnormal functioning of voluntary motion causing resistance to passive motion, caused by a sustained muscle contraction.

What hormone is released in the time of low BG? Counterreggulatory hormones (glucagon, epinephrine, growth hormone, and cortisol) are released to increase blood glucose levels by stimulating glucose production and output by the liver.
Describe function of insulin in the body Insulin enables glucose to pass into the cells to be used as energy.
Explain different Auras pre-seizure Feelings, sense, sensations, smell, taste.
PSA Prostatic Specific Antigen. Used to detect prostate cancer.
Triad of Diabetic care Maintain blood glucose, Nutritional Therapy, Drugs, Excercise. Yes thats 3 but I dont know what she wants.
Why is foot care so important in DM patients Pt can have sensory neuropathy causing decreased sensation so might not know if they have injury or breakdown leading to serious infection. This is caused by reduced blood flow to the feet and legs.
Why is the gonorrhea pt at risk for PID When left untreated it can cause an inflammatory response leading to fibrous tissue formation and adhesions.
How is herpes spread Enters through the mucous membrane or breaks in skin. Once infected it is generally present for life.
Why is ovarian cancer usually dx to late? Early s/s are vague and often dismissed. There are no reliable screening tests and only bimanual pelvic exam can be used to identify an ovarian mass.
