DI vs SIADH Flashcards
How many liters can be lost in 24 hours with a client with DI
5-25 liters
Which disorder causes increased ADH? and why
SIADH
Trauma, infection, small cell Ca, tumor
What can cause ADH deficiency
Neurogenic- issues with pituitary itself
Nephrogenic- issue with kidneys not being able to respond to ADH and concentrate urine
5 S/S of SIADH
Fluid overload = Decreased urine output Decreased deep tendon reflexes Anorexia Headache Fatigue
A client presents with low BP, dry mucosal membranes, polydipsia and report 5-25 liters of urine excreted over the past
Client has DI
A patient who recently underwent cranial surgery develops SIADH. The nurse anticipates that the patient may.... A- have low urine specific gravity B- experience weight gain and edema C- Produce excessive amounts of urine D- Need fluid replacement therapy
B
When caring for a patient being diagnosed with DI the nurse must study and expect to administer which kind of medication?
Desmopressin
Desmopressin is an ADH replacement
Which nursing diagnosis is most likely for a patient with an acute episode of DI?
Defic
Name 3 physical s/s of DI
Dry Mucosal membranes
Dry Skin
Polydipsia
What are classic s/s of DI
Polyuria- 5,000-25,000 Polydipsia- increased thirst, cold water Dry and high labs Very low BP Dry skin/mucosal membranes
What labs will be present with a client with SIADH
Hyponatremia, hypo osmolarity- d/t increased fluid
Hyperkalemia- opposite of sodium
what is the range of specific gravity for someone with DI
<1.005
Which medications do you give in DI
ADH hormone-
vasopressin- IM injection
Desmopressin- intranasal
Which fluids do you give in SIADH and why
.3 % NNS
hypertonic solutions
This helps pull water from overly hydrated cells
What are signs of fluid retention
Crackles, weight gain, JVD
