|
Diabetes insipidus |
Insufficient ADH, kidneys don’t reabsorb water. Normal ADH but no response from kidneys. |
|
|
S/s of DI |
Polyuria, polydipsia, nocturia, dilute urine, dehydration, hypovolemic shock, decreased LoC, death. |
|
|
Diagnosis of DI |
Urine specific gravity <1.001 increased serum osmolarity. Water deprivation test(check urine osmolarity after withholding water) |
|
|
Interventions of DI |
Hypotonic IVF, IV or SubQ Vasopressin, intranasal DDAVP. Thiazide Diuretics if Nephrogenic-stimulate ADH production |
|
|
Nursing Diagnosis of DI |
Deficient Fluid Volume. |
|
|
SIADH |
Too much ADH, water retention, hyponatremia, decreases serum osmolarity(very dilute) |
|
|
Cause of SIADH |
Cancers-bronchogenic lung cancer. Drugs, alcohol |
|
|
S/s of SIADH |
Fluid retention/weight gain. Dilutions hyponatremia, serum osmolarity<275, concentrated urine, muscle cramps, weakness, brain swelling, seizures; death. |
|
|
Diagnostic test of SIADH |
-Urine Chemistry(concentrated) increased urine sodium, increased urine osmolarity. -serum chemistry decreases serum sodium, decreases serum osmolarity. Water load test |
|
|
Interventions SIADH |
Eliminate cause, fluid restriction(500-100ml/day) hypertonic saline IV(pull fluid out of cells) administer diuretics(Lasix) |
|
|
SIADH nursing diagnosis |
Excess fluid volume |
|
|
Growth hormone deficiency |
Deficient GH in childhood. Increase risk for CVA/heart attack. Grow only 3/4 ft. Slowed sexual maturation, May have mental retardation. GH response to induced hypoglycemia. Soma teen SQ or IM. |
|
|
Acromegaly |
Excess growth hormone in adults. Bone growth in width. Organs/connective tissues enlarged. Change in shoe/ring size, nose, jaw brow enlarge. Difficulty speaking and swallowing, sleep apnea, headaches. DM, arthritis, sexual dysfunction. |
|
|
Hypophysectomy |
Lifelong TH, steroid, seed hormone replacement. |
|
|
Medications to decreases blood levels of GH |
Octreotide(sandostatin) Bromocriptine(parlodel) Pegvisomant(somavert)-used to block effects of excessive GH |
