03.01 Syndrome of Inappropriate Antidiuretic hormone (SIADH) for CCRN Review
Included In This Lesson
Study Tools For 03.01 Syndrome of Inappropriate Antidiuretic hormone (SIADH) for CCRN Review
Outline
Nursing Points
General
- SIADH (Syndrome of Inappropriate Antidiuretic Hormone)
- Elevated ADH (Antidiuretic Hormone)
- Antidiuretic hormone (ADH) make kidneys retain fluid
- Decreased sodium levels due to dilution
- Decreased osmolarity (normal 275-295) due to dilution
- Quick formula = sodium level x 2
- Decreased urine output
- Causes (that increase ADH)
- Oat cell carcinoma -> tumor in lung apices that causes ADH
- Viral pneumonia (hypoxia related effects on ADH levels)
- Issues with head
- Increased osmolality
- Anesthesia & analgesics
- Stress
- Complication -> seizure (fluid shifting into cells causing edema in brain)
- Treatment
- Restrict fluids
- Hypertonic solutions -> 3 percent sodium chloride (decrease cerebral edema by moving fluid out of cells)
- Run slow over a few hours
Monitor for CHF - Treat cause
CCRN Review (Critical Care Certification Review)
This course is a review for the CCRN exam. Experienced critical care nurses that meet the testing criteria can use this course to review key concepts for their CCRN exam, which is a certification for critical care nurses. Criteria to test includes having 1,750 hours in direct bedside care of acutely and/or critically ill patients during the last 2 years (prior to the exam). 875 hours need to be worked in the year prior to your application.
