    Triglycerides (TG) Lab Values

    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

    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

    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

    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

    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

    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

Compact and complete

Excellent source for a recap of past classes. It can be essential for new nurses in the floor specially ER, ICU. I love the most the fact that they take just a few minutes and during that time frame explains the basic reasoning for the test and most importantly it’s translation in patient care.
Really wish you could expand the number of tests even though they might not necessarily be common in most institutions.
Great work and thank you for everything you’ve done so far.

Wonderful

These podcasts have been invaluable to studying for nursing school! They're encouraging and easy to understand. I can play them in the car while I'm travelling, at the gym while I'm working out, or just working around the house. Love them.

NRSNG is exactly what the "doctor" ordered!

Thank you so much for creating these podcasts, your hard work is appreciated! The NRSNG program is a tremendous gift for all future nurses, it's exactly what the "doctor" ordered! I can't wait to see you on the other side and call you my colleague. ~ FUTURE RN
