Endocrine Flashcards
SIADH
Syndrome of inappropriate antidiuretic hormone
SI = Soaked Inside
Stop urinating
Sticky and thick urine = high urine specific gravity 1.030 +
Low and liquid labs
Hypo osmolality (low)
Hyponatremia below 135 na+
Sodium low (headache Early sign)
Seizures (from low sodium, headache, confusion)
Server high blood pressure (edema)
stop all fluids + give salt + diuretics
(no IV or drinking) unless it is IV 3% saline + eat salt
SIADH Causes
Pressure on pituitary gland
Small cell lung cancer
Severe brain trauma (surgery)
Sepsis infections of brain (meningitis)
Montior I/O
SIADH Treatment
Monitor I/O
Daily weights
Weight gain = water gain
Anti-Diruetic Hormone
Adds H2O
Created in the pituitary gland
Creates fluid in the body
Synthetic ADH
Synthetic ADH = Demompression, Vasopressin
Given to decrease urine output and increase BP, headaches are huge priory
Labs are low Na+ (135 or less) leading to seizures
Diabetes Insipidus
DI = Dry Inside
Diurese, Drain a lot of fluid
“Die ADH”
Increased urination
Looks dehydrated
Opposite of SIADH
Diluted urine low specific gravity (1.005)
High and dry labs
Hype osmolality (high)
Hypernatremia over 145+ na
Increased thirty
Dry mucosa and skin
Decreased blood pressure
Demopressin “vasopressin” (ADH)
Decrease urine output
Dealth by headache (decreases na+)
DI Causes
Damage to brain
Tumours
Trauma
Surgery
(increased ICP which squeezes pituitary)
Montior I/O
DI Treatment
Montior I/O
Daily weights
Weight loss = water loss
What does the nurse expect to find in a patient with SIADH
Low blood osmolality
Hyponatremia
Decreased urine output
When caring for a patient with SIADH what does the nurse expect to implement
Fluid restriction
Seizure precautions
Monitor urine I/O
A client with a brain tumour develops diabetes insidious which data should the nurse expect to find?
Increased thirst
High blood serum osmolality
A client is newly prescribed demopressin nasal spray, which statement by client indicates further education is needed?
Frequent headaches are normal
Im glad this drug is able to treat my SIADH
I will weight myself weakly
Hypothyroidism
Low and Slow energy
Low T3 and T4
High TSH
Hypothyroidism cause
Iodine deficiency major
Hashimotos
Low dietary iodine
Pituitary tumor
Thyroidectomy (cannot produce any thyroid hormones at all)
Hypothyroidism Signs and symptoms
Hashimoto’s - Low and Slow
Low energy “fatigue weakness, muscle pains and aches
Low metabolism Weight gain/water gain (edema eyes)
Low digestion (Constipation)
Low hair loss “alopecia” not hirsutism
Low mental-forgetful, AlOC (altered)
Low Mood-pression “apathy, confusion)
low libido, low sex drive, infertile
Slow Dry skin turgor
low and slow mensturation “irregular periods”
No period “missed’ = amenorrhea
Slow heavy periods = hypermenorrhea
Hypothyroidism pharmacology
Levothyroxine
leaves T3 and T4 in the body
Life long drug - never stop taking (long slow onset, 3-4 weeks until you see relief)
Early morning x1 daily never at night
Empty stomach
Report S/S of hyperthyroidism (agitation and confusion)
Pregnancy Safe
No FOOD
No cure
No dobling dose
Never abruptly stop taking med
*Avoid narcotics and sedatives (benzodiazepines)
Hypothyroidism Diet
Low calories
Low cholesterol and Sat, Fats
Frequent rest periods
Myxoedema coma extreme low
severe hypothyroidism leading to decreased mental status, hypothermia, and other symptoms related to slowing of function in multiple organs
Low RR - respiratory failure
Priority place “tracheostomy kit” bedside
Key word: “Endotracheal intubation set up
Low BP and HR “hypotension” “bradycardia” (below 60)
Low temp, cold intolerance, no electric blankets
Risk factors; post thyroidectomy
Abrupt STOP of levothyroxine
Hypothalmus and thyroid hormones
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
Hyperthyroidism
High and Hot energy
Graves Disease (gains disease)
High T3 and T4
TSH low
Hyperthyroidism Signs and Symptoms
Graves disease
Grape Eyes “Exothalamos
Us eyepatch/tape down eyelids
Golf balls in throat “Goiter”
High BP - HtN crisis
(MI, CVA< aneurysm)
High HR tachycardia
Heart palpations + atrial fibrillation
High weight loss (high metbolism)
High temp
Hot sweaty skin (diaphoresis)
Diarrhea
Diet Hyperthyroidism
High calories (4000-5000 per day)
High protein and carbs
Frequent meals and snacks (six to eight meals per day)
AVOID:
NO high fibre
NO caffeine
NO spicy food
Thyroid Storm
Aka thyroid toxicosis this will kill the patient
Agitation and confusion are early signs
High HR, High BP
Increased Temp
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 Causes
Excess Iodine
Levothyroxine excess
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
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
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
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
Hyperparathyroidism
Parathyroid glands responsible for regulation of blood calcium (9.0-10.5)
Hypercalcimia
Hypoparathyroidism
Hypocalcemia
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
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)
Addisons Disease Causes
Absent low steroids
Autoimmune (body kills adrenals or pituitary)
Disease: Cancer, infections (TB/HIV)
Damage: adrenal hemorrhage (trauma)
Cushing Causes
High cortisol
Steroids - prednisone long term therapy, makes adrenals think they can stoop producing steroids
Tumor (pituitary adrenal)
Small cell lung cancer
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
Cushing treatment
Control causes
Cut out tumour or steroids (slowly decrease)
Remove of organ = replace hormone, lifelong hormone replacement therapy
Steroid Precautions
prednisone, hydrocortisone, dexemthasone
Swollen (water gain, weight gain)
Sepsis
Hyperglycaemia - increase insulin
Skinny (muscles and bones “osteoporosis”
Sight - Cataracts
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
Adrenal Crisis Treatment
Add steroids IV push
Dehydration (IV NS 0.9%)
dextrose (D50 IV fluids)
