SIADH
and Diabetes Insipidus Posterior pituitary produces ADH (anti-diuretic
hormone) Syndrome of Inappropriate
Anti-Diuretic Hormone.
SIADH=
Too much ADH I remembered it by Soggy Sid
1. Oat cell carcinoma
2.
Viral pneumonia
3.
Head problems
ADH is overproduced and
tells the kidneys to retain fluid.
Fluid
volume excess= hemodilution Low serum Na+ Edema Hypertension, Bounding pulses Weight gain, Low urine output PULMONARY EDEMA and SEIZURES!
Monitor
lung sounds Seizure precautions.

| DIABETES INSIPIDUS |
Diabetes Insipidus
1.
HEAD PROBLEMS
Posterior
pituitary cannot produce ADH.
This
is neurogenic DI Nephrogenic DI occurs when the kidneys cannot RESPOND to
ADH Mainly know the neurogenic form for
testing purposes.
Kidneys
excrete excessive amounts of urine due to lack of production or response to ADH
Up to 20 L per day!
Fluid
volume deficit Hemo concentration with elevated serum Na+ Hypotension, tachycardia. Pulses will be weak and thready Dry mucus
membranes Weight loss, lots of urine output.
HYPOVOLEMIC SHOCK!!
1.
Hypotension unresponsive to treatment is a sign of shock.
2.
Nursing interventions are similar ofr both of these disorders SIADH= Fluid
volume excess.
3.
Diabetes insipidus= fluid volume deficit Monitor HR and BP for both disorders.
4.
Monitor Is and Os for both disorders Daily weights for both disorders.
5.
SIADH: Monitor lung sounds because we are concerned with pulmonary edema HTN
and sezures are additional concerns with diabetes insipidus we are concerned
with hypovolemic shock With DI we
administer Desmopressin.
6.
SIADH= Diuretics and fluid restriction.
