Q

Hypothalmus and thyroid hormones

A

Hypothalamus releases TRH (thyrotropin-relasing hormone) which then tells the anterior pituitary to release TSH (thyroid stimulating hormone)

T4 (thyroid hormone)
T3 (active thyroid hormone)
Calcitonin: (puts a ton off Ca in bone) tones down calcium in the blood by putting it in the bone

thyroid gland suddenly releases large amounts of thyroid hormone in a short period of time. it’s often caused by a sudden and intense (acute) event or situation. Sudden events that can trigger a thyroid storm include: Suddenly stop taking your antithyroid medication. Thyroid surgery (thyroidectomy)

Hyperthyroidism pharmacology
Stop the thyroid from making T3 and T4, slows the thyroid down methimazole: not pregnancy safe PTU propylthiouracil: puts thyroid underground, baby safe Report fever/sore throat SSKI: Potassium Iodide Shrinks the thyroid before removal, stains teeth, keep 1 hour apart from other thryoidism medications Beta Blockers: lol HR increased used to lower HR and BP
26
RAIU: Radioactive iodine Uptake (destroys the thyroid)
Destroys thyroid in one does, monitor for hypothyroidism =extreme lows Before giving: Neg preg test Remove neck jewelry and dentures 5-7 days before hold antithyroid meds NPO 2-4 hours before, 1-2 hours after After Avoid everyone up to 7 days Not pregnant people No crowds Not same restroom (flush 3x) Not same food utensils Not same laundry as your family No cuddling, no kissing
27
Thyroidectomy
Done for hyperthyroidism Airway: monitor for Laryngeal strider Noisy breathing Hoarseness and weak voice #1 priority: Endotracheal tube at bedside Look for bleeding around pillow and insertion site Neutral head and neck alignment NOT supine, HOB 30-45 degrees no flexing or extending neck Low calcium (below 8.6) Remove T check C First sign of low calcium tingling and numbness around mouth and fingers Trousseau and Chvostek
28
Cushing's Disease
Cushion of steroids HIGH “too much steroids" Big, round, hairy High blood pressure High glucose, high sodium big belly “truncal obesity” Moon Face Fat bad lots of hair Hirsutism Stretch marks Red face infections ’slow wound healing’ Risk for fractures - brittle bones
29
Hyperparathyroidism
Parathyroid glands responsible for regulation of blood calcium (9.0-10.5) Hypercalcimia
30
Hypoparathyroidism
Hypocalcemia
31
Addisions disease
Absence of steroids, body does not produce steroids Low Cortisol Low BP Wight loss: Skinny + tan Low Temp Low sodium Hair loss Low glucose High Pigmentation and High Potassium Need to be on life long hormone replacement
32
Addison vs. Cushing pathophysiology
Hypothalamus release CRH (corticotropin releasing hormone) which tells the pituitary to secrete ACTH (adrenocorticotropic hormone) which simulates adrenal gland to produce steroids which controls the 3 S’s Sugar (cortisol) = stress hormone, prednisone S - salt (aldosterone) S - Sex and hair (androgens)
33
Addisons Disease Causes
Absent low steroids Autoimmune (body kills adrenals or pituitary) Disease: Cancer, infections (TB/HIV) Damage: adrenal hemorrhage (trauma)
34
Cushing Causes
High cortisol Steroids - prednisone long term therapy, makes adrenals think they can stoop producing steroids Tumor (pituitary adrenal) Small cell lung cancer
35
Addison Treatment
add steroids during times off stress to avoid Addisons crisis, teach its to tell doctors about stress Diet high in protein, carbs and sodium Don’t stop taking steroids abruptly will cause Addison crisis Don't believe medication will cure you Lifelong hormone replacement therapy
36
Cushing treatment
Control causes Cut out tumour or steroids (slowly decrease) Remove of organ = replace hormone, lifelong hormone replacement therapy
37
Steroid Precautions
prednisone, hydrocortisone, dexemthasone Swollen (water gain, weight gain) Sepsis Hyperglycaemia - increase insulin Skinny (muscles and bones “osteoporosis” Sight - Cataracts
38
Prevent Adrenal Crisis
Slowly tapper off - never abruptly stop steroids always increase dose of steroids with increase stress watch for drop in blood pressure = hypotensive shock
39
Adrenal Crisis Treatment
Add steroids IV push Dehydration (IV NS 0.9%) dextrose (D50 IV fluids)
40
Type 1 Diabetes Mellitus
Auto immune disease Body does not make inulin genetic Insulin dependent for life
41
Insulin
Released when blood sugar is high Puts sugar and potassium in to the cells = sugar and potassium decrease in the blood Increase insulin with stress, sepsis, surgery and steroids If sugar is still high after insulin = critical situation, call doctor
42
Glucagon
When blood sugar is low (exercise or forget to eat) if we do not have food, used to breakdown stored glucose which increase sugar in the blood
43
Type 2 Diabetes Mellitus
Insulin resistant Risk factor based on exercise and diet Sign of insulin resistance Brownish or dark thickening on the neck and armpits, hyperpigmentation and skin tags (canthosis nigricans)
44
Diagnosis Diabetes
Normal Glucose 70-115 Fasting under 100 Hemoglobin a1c less than 6.5 (2-3 month sugar test to see if its are compliant with controlling their blood sugars long term) Compliance Type 2: Diet and exercise Type 1: Insulin
45
Signs and symptoms of Hyperglycemia
Over 115 Polyurea: increased urination Polydipsia: increased thirst Polyphagia: increased hunger
46
Causes of Hyperglycemia
Sepsis (infection) Stress (surgery, hospital stay) Skip insulin Steroids (prednisone)
47
Signs and symptoms of Hypoglycaemia
Most deadly “brain will die” Cool Pale ‘pallor” sweaty, diaphoretic, clammy nervous, anxious, trembling Headache irritable weakness Anxious and trembling Sweat and diaphoresis Hunger
48
Hypoglycemia Treatment
Awake = Ask to eat, juice, soda, crackers, low fat milk or peanut butter Sleep: not alert, unresponsive to painful stimuli = stab with dextrose IV and always reassess sugars
49
Hypoglycaemia
under 70 Causes brain death
50
Causes of Hypoglycemia
Exercise = give extra glucose Alcohol = lowers sugar Insulin Peak times = most at risk for low sugar =, give food
51
A client with type 1 is only responsive to painful stimuli with a blood sugar of 42, what is the first action taken by the nurse
Give dextrose IV push and reassess after 15 minutes
52
Which medication could cause risk for hyperglycaemia
Prednisone
53
The non diabetic client is admitted for a kidney infection that has now turned septic. The blood sugars have. increased from 150 to 225, what is the best answer to give a family member who is asking why insulin is used
High sugar is common during infection and stress to the body, the insulin will help lower the sugar until the infection relsoves
54
Complications off Hyperglycaemia
Blood turns to mud Scars blood vessels = atherosclerosis kidneys = renal failure, creatinine over 1.3 Eyes = retinopathy “blind” frequent eye exams are recommended Nerves = neuropathy (diabetic feet, slow wound healing) Heart = HTN and atheroscerlosis Brain = CVA “stroke”
55
Type 2 diabetes treatment
Diet Exercise Oral meds Insulin (last line)
56
Insulin Test tips
Give foods during peaks, know peak times Deadly Hypoglycaemia (70 or less) No peak, no mix = long acting “old guy” IVP/IV only = regular insulin Draw up inulin: clear to cloudy regular first then NPH Rotate locations, best is abdomen, never aspirate never add eat or massage after sub q infection DKA type 1 - ’sick days’ - YES give insulin
57
Long acting Insulin
No peak No mix = dry up in separate syringes" Detemir Glargine Duration 24 hours +
58
NPH
Intermediate Cloudy Never IV mix clear 2 cloudy given 2x per day Duration 14 hours+ Peak 4-12 hour
59
Regular
Ready to go IV Only IV insulin Duration 5-8 hours Peak 2-4 hours
60
Rapid
Aspart/lispro/glulisine Duration 3-5 hours Most deadly 15 minute onset must be eating Peak 30-90 min
61
Nurse gives regular insulin at 12pm for lunch but patient doesn’t finish their food
2-4pm
62
Metabolic Syndrome
3 or more criteria BP meds or High BP Blood sugar meds or high blood sugar (100+ fasting) Obese was it size 35 + female, 45+ male Lipids “high cholesterol” All contribute to type 2 diabetes
63
Insulin Pumps
Steady dose of insulin Fewer swings in blood sugar Check 4 times per day push insulin bolus button at meal times Always asses pt first and then machine second
64
Oral agents - Type 1 diabetes
Never take PO meds with Iron Calcium Anti acids Tums Metformin Glipizide and Glyburide: heart can die, slow position changes Thiazolidinedione (TZD) pioglitazone - one dead heart Acarbose and precose “flatus and diarrhea
65
Diabetes Education
