Assess fluid balance a. #1 priority: weighing o POMC (Pro Opioids Melano Cortin) b. Check vital signs ▪ MSH – Melano Stimulating Hormone c. Check and monitor intake and output d. Check urine output Increased: 2. Limit fluid intake o ACTH 3. Limit sodium intake (less than 2g/dL) 4. Antihypertensive Drugs o MSH 5. Diuretics COLLABORATIVE AS ORDERED ▪ Increased Melanin (Darkening of Skin) a. K – SPARING = SPIRONOLACTONE b. Formal: Aldosterone Antagonist Featured: c. Informal: Potassium Sparing Diuretics o Tanned complexion ELECTROLYTE IMBALANCE Muscle (weak) o Bronzed complexion Affects the heart ▪ Darkened Skin Increase Na, Decreased Potassium Management: Sodium Restriction / Potassium Supplementation 1. Diet IN ADDISON’S a. ✕ – Salty food, Processed food, Preserved food Decreased Aldosterone → Decreased Na + Decreased H2O = b. ✓– K-Supplementation (pinipitas → banana, avocados, citrus fruits). Best is Decreased BP and Weight apricot. No apples, pears. 2. Supplement Potassium Chloride – 3.0 and above a. Oral LEVEL OF CONSCIOUSNESS i. Above 3.0 ii. K – lyte In the brain iii. Kalium (Kalingen) o NEURONS iv. Both with melas and juice b. Parenteral ▪ Continuous brain conduction = slow i. Below 3.0 ▪ SALTatory Conduction = Fast ii. IV Incorporation iii. PNSS, 40 mEq/L of NSS → Na + → Brain iv. 10 mEq of K Chloride per hr 3. Monitor a. Urine Output INCREASED K+ = HYPERKALEMNIA i. ✕ Kidneys → Increased Potassium – Hyperkalemia Muscle (Skeletal, Smooth and Cardiac) ii. Normal Urine Output: 30 – 60 mL/hr iii. If
