Sodium level 135-145 mEq/L Insufficiencient water intake Potassium level 3.5 -5.5 mEq/L Low means GI loss renal loss Calcium Level 8.5 -10.9 mg/L Low means decreased albumin levels Chloride level 95 -l05 mEq/L Low means vomiting Magnesium level l.5 - 2.5 mEq/L low means hemodialysis Phosphorus level 2.5 - 4.5 mg/dL Low means hyperparathyroidism Red blood cell -RBC 4.5 - 5.0 million Decreased in anemia White blood cell WBC 5,000 - 10,000 decreased in viral infection Pit Blood value 200,000 - 400,000 Hgb Blood value 12-16 gms women; 14-18 gms men Decreased in anemia ABG - HCO 3 24 - 26 mEq/L ABG CO 2 35 - 45 mEq/L ABG PaO 2 80% - 100% ABG SaO2 >95% Glucose values 70 - 110 mg/dL BUN Value Blood Urea Nitrogen 7-22 mg/dL Low means fluid overload Rule of nines for calculating TBSA for burns Head = 9%, Arms= 18% (9% each), Back = 18%, Legs +36% (18% each), Genitalia = 1% Definition of R.O.M.E. Respiratory opposite/Metabolic equal Respiratory acidosis pH down, cO 2 up, and HCO 3 up pH<7.35 PaCO2>45 Metabolic Acidosis pH down, cO2 down, and HCO 3 down pH<7.35 HCO3<22 Respiratory Alkalosis pH up, cO2 down, and HCO3 down pH>7.45 PacO2<35 Metabolic Alkalosis pH up, cO2 up, and HCO3 up pH>7.45 HCO3>26 antacids Reduce hydrochloric acid in the stomach Antianemics Increase red blood cell production Anticholenergics Decrease oral secretions Anticoagulants Prevent clot formation Anticonvulsants Used for management of seizures/bipolar disorder Antidiarrheals Decrease gastric motility and reduce water in bowel Antihistamines Block the release of histamine Antihypertensives Lower blood pressure and increase blood flow Anti-infectives Used for the treatment6 of infections Bronchodilators Dilate large air passages in asthma/lung disease Diuretics Decrease water/sodium from the Loop of Henle Miotics constrict the pupils Mydriatics Dilate the pupils Narcotics/analgesics Felieve moderate to severe pain Prothrombin Time (PT) High means blood less likely to clot Normal range 9.9-13.l seconds International normalized ratio (INR) High means clotting ability is diminished Normal range 0.69-1.37 Partial thromboplastin time (PTT) Low in early DIC and in erxtensive cancer; high means blood is thin due to clotting disorder or medication such as heparin Normal range 25.8 - 34.6 seconds Platelet count Low means diminished clotting ability, very low counts mean spontaneous bleeding may occur; high means increased clotting ability, potential for platelet clumping. Normal range l32-413 x l0-3/mm3 Hematocrit (Hct) Decrease in anemia Normal range 34.3-44.4% Erythrocyte sedimentation rate (ESR) Low means anti-inflammatories--High means inflammation Normal range 0-30 Med Surg
