1

What is an antidiuretic hormone (ADH)

controls BP and blood volume by regulating reabsorption/excretion of water in the kidneys

2

What do high levels of ADH cause

reabsorption of water

3

What do low levels of ADH cause

excretion of water

4

Where is ADH secreted from?

Posterior pituitary gland

5

When is ADH secreted?

when body senses low blood volume, low BP, and hypernatremia

6

What is Diabetes Insipidus?

Insufficient ADH released, resulting in kidneys being unable to concentrate urine

7

Neurogenic pathophysiology of Diabetes Insipidus

pituitary tumor or injury causes insufficient ADH hormone to be released

8

Nephrogenic pathophysiology of Diabetes Insipidus

Inadequate kidney response to ADH r/t kidney infection

9

Most common sign of Diabetes Insipidus

large amounts of dilute urine

What will the blood pressure of a Diabetes Insipidus patient have

hypotension

12

What will be the hydration status of a Diabetes Insipidus patient

-dehydration

-polydipsia (excessive thirst)

13

Urine lab values indicating Diabetes Insipidus

Decreased urine specific gravity (<1.005)
Decreased osmolality (<200)
Decreased sodium

14

Blood lab values indicating Diabetes Insipidus

-Increased osmolality >300)
-Increased sodium

15

What medication will be given for a patient with Diabetes Insipidus

-Vasopressin (hormone)
-Desmopressin (ADH)

16

Nursing care for a patient with Diabetes Insipidus

-monitor I&O
