PACKAGE WITH SOLUTIONS) QUESTIONS & ANSWERS
| GRADE A | 100% CORRECT (VERIFIED SOLUTIONS)
SIADH .....ANSWER.....too much water, dilutional hyponatremia.
Decreased osmolarity=hypoosmolar. Decreased urinary output.
CSF normal protein, glucose, WBCs, specific gravity,
.....ANSWER.....Protein <100, Glucose: 70 WBCs: 4 cells/mm2
Specific gravity 1.007
Poikothermia .....ANSWER.....fluctuation of core body
temperature of more than 2° C due to changes in ambient room
temperature
pathophysiology of a seizure .....ANSWER.....neurons in the
cerebral cortex fire at the same time in a paroxysmal burst.
,Page 2 of 116
System driven outcome .....ANSWER.....include length of stay,
readmission rate, and resource utilization.
Arterial supply to the brain: vertebrobasilar, common carotid,
meningeal arteries .....ANSWER.....The vertebrobasilar arteries
supply the posterior portion of the brain. The common carotid
arteries supply the anterior area of the brain. The meningeal
arteries supply the superior portion of the brain.
Pheochromocytoma .....ANSWER.....adrenal medulla,hi
epi/norepi. s/s: hypertension, sweating, headache, palpitations,
apprehension, nausea/vomiting, tremor, pallor, abdominal pain,
chest pain, and hyperglycemia.
Acute radiation syndrome .....ANSWER.....large doses of ionizing
radiation , Circulatory collapse, increased intracranial pressure,
vasculitis, and meningitis causing death within 3 days
Complications of SIADH .....ANSWER.....seizure activity
,Page 3 of 116
Treatment of SIADH (avoid what solutions?) .....ANSWER.....Fluid
restriction
3% nacl (1500 osmolarity over 25cc/hr or less)
Dont do hypotonic solutions!
Asses for fluid overload
hypertonic solutions .....ANSWER.....D5LR; D5 1/2 NS; D5NS
hypotonic solutions .....ANSWER.....0.5% NS (HNS or 0.45% NS);
2.5% dextrose in 0.45% NS (D2.5 45% NS)
Osmolality and Sodium .....ANSWER.....275-295= normal
osmolality. Sodium=135-145. Usually 2X of Na
Causes of SIADH .....ANSWER.....Viral PNA
Oat cell carcinoma
Head problems
Increased serum osmolality
, Page 4 of 116
Anesthesia and analgesics
Stress
Diabetes insipidus (urine specific gravity?) .....ANSWER.....No
ADH, can't keep water, increased UOP. Hypernatremic,
hyperosmolar, increased urinary output (6-24L a day of clear
urine)
urine specific gravity 1.001-1.005
Severe hypovolemia
Causes of diabetes insipidus (what medication?)
.....ANSWER.....Head problem
Dilantin (DI)
Treatment of diabetes insipidus (medication, fluid, monitoring x2)
.....ANSWER.....Pitressin/vasopressin (same as ADH)
Give fluids (increase intravascular volume)
Monitor urine specific gravity
