5 Matching Questions

  1. diffusion
  2. hypokalemia
  3. respiratory acidosis
  4. hypertonic
  5. osmolality
  1. a acidosis resulting from reduced gas exchange in the lungs (as in emphysema or pneumonia or hypoventilation)
  2. b when comparing two solutions, the solution with the greater concentration of solutes
  3. c the process by which molecules move from an area of higher concentration to an area of lower concentration
  4. d the concentration of solutes in body fluids
  5. e abnormally low level of potassium in the circulating blood leading to weakness and heart abnormalities

5 Multiple Choice Questions

  1. pressure exerted by plasma proteins on permeable membranes in the body; synonym for oncotic pressure, opposes the forces of hydrostatic pressure, pulls fluid back into capillaries
  2. VAD, devices such as a needle, cannula, or catheter that allow direct access to the circulatory system
  3. Hormone that constricts blood vessels, resulting in increase in blood pressure. A normal blood protein produced by the liver, angiotensin is converted to angiotensin I by renin (secreted by kidney when blood pressure falls). Angiotensin I is further converted to angiotensin II by ACE (angiotensin converting enzyme). Angiotensin II is a powerful systemic vasocontrictor and stimulator of aldosterone release, both of which result in an increase in blood pressure.
  4. increases 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
  5. ADH. hormone secreted by the posterior pituitary gland and also by nerve endings in the hypothalamus

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. infusion pumpthe process by which molecules move from an area of higher concentration to an area of lower concentration

          

  3. colloidsparticles are mixed together and not dissolved, particles are relatively large and are permanently suspend (whipped cream)

          

  4. hypomagnesemiaabnormally low level of calcium in the blood

          

  5. filtrationa process that separates materials based on the size of their particles
