- vascular access device
- a abnormally low level of potassium in the circulating blood leading to weakness and heart abnormalities
- b inflammation of a vein (usually in the legs)
- c A decrease in the amount of water in body tissues
- d (of a solution) having a lower osmotic pressure than a comparison solution
- e VAD, devices such as a needle, cannula, or catheter that allow direct access to the circulatory system
5 Multiple Choice Questions
- difference between the concentrations of serum cations and anions, determined by measuring the concentrations of sodium cations and chloride and bicarbonate anions.
- the presence of abnormally high levels of calcium in the blood
- a serious, and potentially fatal, complication of a blood transfusion in which a severe immune response occurs because the patient's blood and the donated blood do not match
- A peptide hormone secreted by cardiac atrial cells in response to atrial distension (increased blood flow); causes increased renal sodium excretion and as such lowers blood pressure (antagonizing aldosterone). causes vasodilation and osmoregulation.
- The osmotic pressure in the blood vessels due only to plasma proteins (primarily albumin) --> causes water to rush back into capillaries at end.
5 True/False Questions
renin → enzyme that is produced by the kidney; important for blood pressure and volume regulation; catalyzes the conversion of circulating angiotensinogen to angiotensin I
hypernatremia → abnormally low level of sodium in the blood
crystalloids → electrolyte solutions that move freely between the intravascular compartment and interstitial spaces
hydrostatic pressure → the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane
colloids → water moves from a more dilute solution (of a solute) to a more concentrated solution (of the solute) through a membrane that is permeable to the solvent until the solution is equalized
