Endocrine Reading Flashcards by Madison North

Describe the effects of aging on the endocrine system.

Aging lowers your hormone levels and tends to cause some disorders that will generally only occur in elder age groups
lowers metabolism, ADH production, and estrogen

What is the significance of a ‘halo’ on a drip pad after a hypophysectomy?

The halo is cerebrospinal fluid around blood
- Test for blood glucose with dipstick
Bad thing can need to be let out through lumbar puncture

How does increased ADH levels impact fluid volume?

Increased ADH level cause and excess of water and a decrease of sodium
- An increase in the release of ADH makes your body hold on to water causing fluid volume retention while depleting the levels of electrolytes that you have
Normally caused by pituitary surgery, trauma, head injury, CVA or infection like meniginitis or a malignant tumor

What impact does SIADH and/or DI have on sodium, other electrolytes, and osmolality?

SIADH = low Na, BUN, Hct
- serum osmolality low
- urine osmolality HIGH (concentrated)
DI = high Na
- serum osmolality HIGH
- urine osmolality LOW (DILUTE POLYURIA)

What medications are used to treat SIADH and DI? Give major side effects and patient education needs

DI - Desmopressin acetate
- 2. Erythema of injection sites, nasal irritation, hyponatremia, doesn’t raise BP
3. Cant use concurrent loop diuretics or glucocorticoids and must hold is creatinine clearance <50mL/min
4. Drug choice for DI and is more effective than vasopressin
5. Must monitor I&O, serum and urine osm, daily weight, assess for hypo/hypervolemia
6. No alcohol, medical alert bracelet and how to administer, nasal spray is the cheapest and most common
DI - Vasopressin
1. Very similar to their natural hormone
2. Promotes renal conservation of water
3. Vasoconstriction and increases BP, HA, chest pain and water intoxication
4. Don’t use if they have chronic renal failure
5. Monitor BP, HR, EKG, I&O, urine osm, dehydration vs. fluid overload
6. Teach no alcohol, medic alert ID band, limit fluid intake
7. Very important to know that they are on this drug

SIADH priorities

i. Safety and precautions for seizures depending on their sodium levels
ii. Can restrict fluid as this is the easiest way to help with fluid retention; may restrict to 800-1200 mL a day counting IV/IVPB and frozen items, if severe enough we will restrict to 500 mL
iii. Daily weight
iv. Strict I&Os
v. VS, CV, and neuro checks frequently

DI priorities

i. Identify and correct underlying issue
ii. Replace ADH
iii. Monitor VS, CV, and neuro frequently
iv. Daily weight and strict I&Os

Top patient teaching needs for SIADH and DI.

SIADH = report wt gain, slow Na gradually, fluid restrictions, seizure and electrolyte balance

How are TSH, T3 and T4 levels impacted in hyper or hypo thyroidism?

a. TSH is a measurement for testing thyroid function and manages thyroid replacement therapy; produced by pituitary gland and stimulates the production of T3 and T4
i. Both T3 and 4 will be high in hyperthyroidism while low in hypo
b. T3 accurately measures hyperthyroidism and evaluates the thyroid levels after admin of iodine
c. T4 measures free and unbound thyroxine levels in your bloodstream

Name 5 manifestations of hyperthyroidism

Study These Flashcards

a. Nervous tremor
b. Weight loss and hunger

Name 5 manifestations of hypothyroidism

Study These Flashcards

a. Lethargy and fatigue
b. Weight gain
c. Dry skin and hair
d. Constipation
e. intolerance to cold

How do manifestation of hyper/hypo thyroidism differ in the older adult?

Study These Flashcards

Double the wt loss from anorexia as well
dysrhythmia to heart failure more common

What medications are used to treat hyperthyroidism? Common side effects & key patient teaching points

Study These Flashcards

lifelong antithyroid med - PTU (hypothyroidism, agranulocytosis, fetal harm) - not abrupt stop
Iodine 131 : radioactive precautions (radiation sickness, bone marrow suppression, hypothyroid) - not for pregnant or children
Strong iodine solution = iodism toxicity (avoid ionized foods)
Thyroidectomy

What medications are used to treat hypothyroidism? Common side effects & key patient teaching points

Study These Flashcards

levothyroxine (Synthroid) = thyrotoxicosis
Extremes; jitters, grumpy, thyroid storm
- not for acute MI, stroke, or thyroid storm
- in morning before breakfast

List 3-5 priorities in post thyroidectomy care.

Study These Flashcards

head & neck support (pillows, no rocking forward with head to strain the neck, use arms to side for pushing)
HOB for swelling
feeding tubes?
incision painful to swallow for 24 hours - pain meds before food
Incision & airway: bleeding (anterior and side collarbones), airway obstruction
thyroid hormone: depends on the amount left, if total lifelong thyroid replacement, weaning can occur but usually very slow

What are the nutrition requirements or precautions for patients with hypo / hyperthyroidism?

Study These Flashcards

a. Iodine is a main component
b. Hyper affects the metabolism of fats, carbs, and proteins

What are manifestations and top priorities of care in Thyroid Storm/Crisis?

26. What electrolyte(s) does parathyroid function impact? How is that manifested?

a. Calcium as calcium is regulated by PTH hormone b. If serum ca increases i. Parathyroid increases PTH level and Ca is drawn from bone and increases serum Ca levels c. if serum Ca decreases i. thyroid increases calcitonin which decreases serum Ca

35. What is the difference between glucocorticoids and mineralocorticoids?

Gluco =carb metabolism (genesis, lower utilization peri,inhibit uptake, and promote storage) - protein metabolism - fat metabolism - CV function Minerals = RAAS = Aldosterone Promotes sodium & potassium hemostasis**
