GUARANTEED PASS
1. Antidiuretic hormone (ADH): which is responsible for the
body's regulation of water, is produced in the hypothalamus and
stored in the posterior pituitary.
2. ADH: this hormone is released into the bloodstream in
response to high plasma osmolality which causes the kidneys to
respond by increasing water reabsorption.
3. (SIADH) and (DI).: Two disorders of ADH regulation that can
potentially lead to fatal sodium imbalances are
4. SIADH secretion: levels of ADH are inappropriately
elevated compared to the body's low osmolality, ADH levels are
not suppressed by further decreases in blood osmolality this is
,5. CNS (SIADH) risk factors: Meningitis, encephalitis,
hydrocephalus, brain tumors and hemorrhages, anoxic
encephalopathy, Guillain-Barre syndrome, delirium tremens, head
trauma, multiple sclerosis, amyotrophic lateral sclerosis (ALS),
pituitary surgery, etc these are risk factors in
6. pulmonary (SIADH) risk factors: pneumonia, asthma,
positive end-expiratory pressure (PEEP) ventilation,
pneumothorax, cystic fibrosis, tuberculosis, etc. these are risk
factors related to
7. Drugs (SIADH) risk factors: vasopressin, desmopressin,
serotonin reuptake inhibitors, vincristine, vinblastine,
carbamazepine, cyclophosphamide, opiates, nicotine, tricyclic
antidepressants (TCA), monoamine oxidase inhibitors (MAOIs),
phenothiazines, etc. drugs related to risk factors of
8. unregulated tumor producing ADH (SIADH): oat cell lung,
Ewing's sarcoma, mesothelioma, thymoma, bronchial adenoma,
pancreatic carcinoma, duodenal carcinoma, etc these risk factors
for
, 9. SIADH clinical presentation: mild symptoms-130-135
mEq/L, Moderate symptoms-121-129 mEq/L, severe symptoms-
drops below 120 mEq/L are considered clinical presentation to
10. serum sodium < 120 mEq/L: seizures, hypothermia, and
death are considered severe symptoms of NA at
11. hyponatremia (Lethargy): confusion, combativeness,
headache, decreased or low urine output (UOP), are symptoms of
12. hyponatremia (Apathy): agitation, nausea, muscle cramps,
Mood Changes disorientation, vomiting, generalized muscle
weakness are all symptoms of
13. SIADH (renal) differential diagnoses: RF, renal loss from
diuretics, mineralocorticoid deficiency (ACE) inhibitors, adrenal
insufficiency, severe nephrotic syndrome, cirrhosis with portal
hypertension, (CHF) are all differentials for
14. SIADH (extrarenal) differential diagnoses: dehydration,
bowel obstruction, (GI) losses (excessive vomiting or diarrhea),
HF, hypothyroidism, cirrhosis nephrosis, hypoalbuminemia are
differential for
