Unit 1 - Endocrine Problems Flashcards
What is Syndrome of Inappropriate Antidiuretic Hormone (SIADH)
Abnormal secretion of ADH by the posterior pituitary gland
What are the manifestations of SIADH?
Fluid retention, serum hyper-osmolality, dilution also hyponatremia, hypochloremia, concentrated urine, increased intravascular volume, and normal renal function
What is the most common cause of SIADH?
Lung cancer
What is the goal of treatment in SIADH?
Restore fluid and electrolyte balance
What are the fluid restrictions for minor cases of SIADH?
800-1000 ml/day
What are the treatment for severe SIADH?
Fluid restrictions of 500mL/day, IV hypertonic saline, IV Lasix, and Tolvaptan to block ADH effect on renal tubule
What must be monitored in the acute care of SIADH?
Decreased U/O with increased concentration, sudden increase in weight or decrease in Na
What assessments are necessary for acute care of SIADH?
LOC, VS, I&O, Urine concentration, daily weight, s/s hyponatremia, heart & lung sounds
What are nursing managements for SIADH?
HOB flat, protect from injury, ice chips to relieve thirst, offer gum, hard candy to suck on or moisture spray for thirst
What is diabetes insipidus (DI)?
Deficiency in production or renal response to ADH
What are the manifestations of DI?
Polydipsia, polyuria, fluid and electrolyte imbalances, and increased serum osmality
What are the types of DI?
Neurogenic, nephrogenic, and psychologic
What is neurogenic DI?
Lesion in brain interferes with synthesis, transport, or release of ADH
What is nephrogenic DI?
Decreased renal response to ADH
What is psychologic DI?
Structural lesion in thirst center or psychological disorder causes increased fluid intake
