5 Matching questions

  1. isotonic
  2. phlebitis
  3. alkalosis
  4. osmolality
  5. buffer
  1. a inflammation of a vein (usually in the legs)
  2. b the concentration of solutes in body fluids
  3. c (used of solutions) having the same or equal osmotic pressure
  4. d a condition that occurs with increases in blood bicarbonate or decreases in blood carbonic acid; blood pH above 7.45 (low hydrogen ion concentration)
  5. e weak acid or base that can react with strong acids or bases to help prevent sharp, sudden changes in pH. It maintains a fairly constant pH in a solution by accepting H+ ions when their levels rise and donating H+ ions when their levels fall

5 Multiple choice questions

  1. a condition characterized by a deficiency of bicarbonate ions in the body in relation to the amount of carbonic acid in the body, in which the pH falls to less than 7.35
  2. a substance that dissolves in water to give a solution that conducts an electric current
  3. TNP, administration of a nutritionally adequate solution through a catheter into the vena cava
  4. (of a solution) having a lower osmotic pressure than a comparison solution
  5. 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.

5 True/False questions

  1. osmotic pressureThe osmotic pressure in the blood vessels due only to plasma proteins (primarily albumin) --> causes water to rush back into capillaries at end.


  2. diffusiona homogeneous mixture of two or more substances


  3. osmolaritythe concentration of solutes in body fluids


  4. solventnegatively charged ions


  5. fluid volume deficitincreases interstitial and vascular volumes, hypertension; tachycardia; strong bounding pulses; moist crackles/wheezes; jugular vein distension; dependent edema; taut skin turgor; low or normal urine output; low urine specific gravity; weight gain
