By Jon Haws RN: Critical Care Nurse NCLEX Educator Quick . . . is the aPTT within normal range? Are you sweating a bit? Nervous? Head over to NURSING.com/freebies for our free cheat sheet covering the 63 most important lab values for nurses. This podcast covers one essential lab value for episode including normal ranges, nursing considerations, and background information. Normal lab values are hard to keep straight. This show includes the most common including: Creatinine, WBC, BUN, aPTT, blood gasses, and more. Welcome to the Nursing family! For full disclaimer information visit nursing.com.

    Triglycerides (TG) Lab Values

    Normal Indications Evaluate for: Elevated triglycerides Risk for atherosclerotic heart disease and stroke Description Triglycerides (TG) are required to provide energy during the metabolic process, excess triglycerides are stored in adipose tissue. What would cause increased levels? Myocardial Infarction (MI) Alcoholism Alcoholic cirrhosis High carbohydrate diet Anorexia nervosa Cirrhosis Hypertension (HTN) Nephrotic Syndrome Obesity Renal failure Pancreatitis Stress What would cause decreased levels? Chronic Obstructive Pulmonary Disease (COPD) Liver disease Hyperthyroidism Malnutrition Malabsorption

    Sodium (Na+) Lab Values

    Normal 135-145 mEq/L Indications Monitor: Extracellular osmolality Electrolyte imbalance Description Sodium (Na+) is the most abundant cation in extracellular fluid. Sodium aids in osmotic pressure, renal retention and excretion of water, acid-base balance, regulation of other cations and anions in the body. Sodium plays a role in blood pressure regulation and stimulation of neuromuscular reactions. Sodium and water have a direct relationship; water follows salt. What would cause increased levels? Cushing Syndrome Hyperaldosteronism Dehydration Burn injury Azotemia (elevated nitrogen) Lactic acidosis (LA) Fever/excessive sweating Excessive IV fluids containing sodium Diabetes Insipidus Osmotic diuresis What would cause decreased levels? Congestive Heart Failure (CHF) Syndrome of Inappropriate Antidiuretic Hormone (SIADH) Cystic Fibrosis Diuretic use Metabolic acidosis Addison’s Disease Nephrotic Syndrome Vomiting Diarrhea Ascites Excessive Antidiuretic Hormone(ADH) Liver failure

    Potassium (K+) Lab Values

    Normal 3.5 - 5.0 mEq/L Indications Evaluate: Electrolyte imbalances Cardiac arrhythmias Monitor patients who are: Acidotic Receiving diuretic therapy Description Potassium (K+) is the most abundant intracellular cation and plays a vital role in the transmission of electrical impulses in cardiac and skeletal muscle. It plays a role in acid base equilibrium. In states of acidosis hydrogen will enter the cell which will force potassium out of the cell. A 0.1 decrease in pH will cause a 0.5 increase in K+. What would cause increased levels? Renal failure Hypoaldosteronism Addison’s disease Injury to tissues Diabetes Mellitus (DM) Ketoacidosis Hyperventilation Acidosis Infection Dehydration Burns What would cause decreased levels? Hyperaldosteronism Excess insulin Alkalosis Diarrhea Vomiting Cystic Fibrosis Cushing Syndrome

    Partial Thromboplastin Time (PTT) Lab Values

    Normal 25 - 35 seconds Indications Detection of coagulation disorders Evaluate response to Heparin (PT for Coumadin) Preoperative assessment Description Partial Thromboplastin Time (PTT)evaluates the function of factors I, II, V, VIII, IX, X, XI, and XII. PTT represents the amount of time required for a fibrin clot to form. Monitors therapeutic ranges for people taking Heparin. What would cause increased levels? Disseminated Intravascular Coagulation (DIC) Clotting Factor Deficiencies: Hypofibrinogenemia Von Willebrand Disease Hemophilia Liver disease: Cirrhosis Vitamin K deficiency Polycythemia Dialysis What would cause decreased levels? N/A

    Oxygen Saturation (SaO2) Lab Values

    Normal 95 - 100% Indications Determine respiratory status Part of Arterial Blood Gas (ABG) testing Description Oxygen saturation (SaO2) is a measurement of the percentage of how much hemoglobin is saturated with oxygen. Oxygen is transported in the blood in two ways: oxygen dissolved in blood plasma (pO2) and oxygen bound to hemoglobin (SaO2). About 97% of oxygen is bound to hemoglobin while 3% is dissolved in plasma. SaO2 and pO2 have direct relationships, if one is decreased so is the other. The relationship between oxygen saturation (SaO2) and partial pressure O2 (PaO2) is referred to as the oxyhemoglobin (HbO2) dissociation curve. SaO2 of about 90% is associated with PaO2 of about 60 mmHg. What would cause increased levels? Polycythemia Increased inspired O2 Hyperventilation What would cause decreased levels? Anemia’s Hypoventilation Bronchospasm Mucus plugs Atelectasis Pneumothorax Pulmonary edema Adult respiratory distress syndrome

    Osmolality Lab Values

    Normal 261 – 280 mOsm/kg Indications Monitor: Electrolyte balance Acid-Base balance Hydration Evaluate function of antidiuretic hormone.   Description Osmolality is a measure of the particles in solution. The size, shape, and charge of the particles do not impact the osmolality   What would cause increased levels? Dehydration Azotemia Hypercalcemia Hyperglycemic Hyperosmolar Nonketotic State (HHNS) Hypernatremia Diabetes Insipidus Hyperglycemia Mannitol therapy Uremia Severe pyelonephritis Shock Ketosis   What would cause decreased levels? Hyponatremia Syndrome of Inappropriate Antidiuretic Hormone (SIADH) Overhydration

    Magnesium (Mg) Lab Values

    Normal 1.6 – 2.6 mg/dL Indications Monitor: Renal failure Chronic alcoholism Cardiac arrhythmias Description Magnesium (Mg) is a cation necessary for protein synthesis, nucleic acid synthesis, muscle contraction, ATP (adenosine triphosphate) use, nerve impulse conduction, and blood clotting. Magnesium affects the absorption of sodium, calcium, phosphorus, potassium.   What would cause increased levels? Renal insufficiency Uncontrolled Diabetes Mellitus (DM) Addison Disease Dehydration Hypothyroidism Overuse of antacids Tissue trauma   What would cause decreased levels? Alcoholism Diabetic acidosis Renal failure: Glomerulonephritis Hypercalcemia Malnutrition Malabsorption Hypoparathyroidism Diarrhea

    Low Density Lipoprotein (LDL) Lab Values

    Normal Indications Useful in determining risk of cardiovascular disease. Description Cholesterol is transported via lipoproteins. There are multiple types of lipoproteins and they each have slightly different functions: high-density lipoprotein (HDL), low-density lipoprotein, LDL, and very low-density lipoprotein (VLDL). LDL cholesterol is considered bad cholesterol because as it travels through the blood, it deposits cholesterol into the lining of blood vessels, causing atherosclerosis and an increase in cardiovascular disease. What would cause increased levels? Diet high in saturated fats Nephrotic Syndrome Alcoholism Chronic liver disease: Hepatitis Cirrhosis Hypothyroidism Cushing’s Syndrome What would cause decreased levels? Regular physical activity Hyperthyroidism Hypoproteinemia: Malabsorption Severe burns Malnutrition
