EF - FLUID ELEC ACID BASE Flashcards
· acid–base balance
o The homeostasis of acidic and basic (alkaline) compounds in the blood to maintain a blood pH of between 7.35 and 7.45.
· acidosis
o Levels of acid in the blood are too high, a pH of less than 7.35.
· active transport
o The movement of electrolytes or molecules across a cell membrane with the use of energy in the form of enzymes.
· air embolism
o Obstruction of a vessel by air.
· alkalosis
o The blood is too alkaline, a pH of greater than 7.45.
· antidiuretic hormone (ADH)
o A hormone excreted by the hypothalamus in the brain that maintains blood pressure and fluid volume. Also known as vasopressin.
· antigens
o Substance that can trigger an immune response if foreign in the body.
· apoptosis
o Destruction of a cell.
· arrhythmias
o Abnormal heart rhythm.
· basic metabolic panel (BMP)
o A blood test that provides information regarding electrolyte and fluid balance and includes information regarding renal function and glucose levels.
· blood type
o A classification of the blood that includes 4 main groups: A, B, AB and O.
· bradycardia
o A heart rate that is less than the expected reference range.
· central venous access devices (CVADs)
o Device inserted in the body through a central vein such as the subclavian or jugular and allows administration of fluids, blood, medications, and other therapies.
· Chvostek sign
o Test which may indicate low calcium or magnesium levels. A positive result results in a twitching response of the side of the face when facial nerves are tapped.
· circulatory overload
o A complication of IV therapy in which too much fluid is administered too quickly.
· colloidal solutions
o Intravenous solutions that contain large molecules unable to pass through capillary membranes.
· complete metabolic panel (CMP)
o A blood test that provides information regarding electrolyte and fluid balance. In addition to those findings included in the BMP, the CMP also includes information regarding the body’s metabolism, including protein and liver function.
· creatinine (CR)
o Reflection of renal function; a byproduct of skeletal muscle contractions (creatine), which is then excreted through the urine.
· dehydration
o Excess water loss without a loss of sodium.
· diffusion
o Movement of solutes from an area of higher concentration to one of lower concentration.
· diuretics
o A category of medications that cause increased urination.
· edema
o Swelling due to excess fluid.
· electrocardiogram (ECG)
o A test to check heart activity including heart rate and rhythm.
· electrolytes
o Minerals in the body that conduct electricity.
