part 3 Flashcards
How can Hyperkalemia be treated?
- tx underlying cause
- restrict intake: food, PO meds, IV replacements
- kayexalate (for mild symptoms, this gives pt diarrhea)
- IV (given when K+ is around 6: ca gluconate, sodium bicarbonate, IV insulin (regular only), hypertonic dextrose
- peritoneal dialysis or hemodialysis
- Beta2 agonist (albuterol)
- Other important interventions: check HR/cardiac monitor, re-check K+ labs and EKG, vitals
What are some signs of hypocalcemia?
Chvostek sign (face) and Trousseau’s sign (hand), seizures, muscle spasm, paresthesia
What can cause hypocalcemia?
hypoparathyroidism
hypoalbuminemia
