  1. a CPK, Tropnin I, Troponin T
  2. b mixed color, hyper, normo and hypochromic in one sample
  3. c Auris uterque (AU), both ears
  4. d Auris sinistra (AS), left ear
  5. e Syringe collections:pulling back forcibly on the plunger draws blood too quickly through the needle shearing cell membranes, transferring blood into a vaccuum tube further traumatizes red blood cells, pump plunger several times before use to loosen it w/in the barrell. Pace the aspiration rate so that there is no more than 1 mL of air space at any time. Transfer blood into vaccuum tube immediately, preferably using a transfer device

5 Multiple choice questions

  1. Potassium (K)—helps in the clotting of blood; is an electrolyte, an ion and is critical to muscle (muscle contractions) and nerve function and for the transportation of nutrients and cellular wastes across cellular membranes.
    K is controlled by aldosterone, a hormone.
    Uncontrolled diabetes or excessive vomiting/diarrhea can cause abnormal K levels.
    Both high and low volume of potassium can cause problems with the heart so it is important to monitor the patient's potassium after surgery. Patients that are taking diuretics regularly should have their potassium checked as diuretics cause the kidney to release too much potassium
  2. Distance visual acuity is typically assessed using a Snellen chart. May use E chart, pediatric picture chart, or alphabet chart Patient stands 20 feet from chart at eye level Eyes tested with corrective lenses worn Record results as fraction with 20 feet on top Visual acuity is expressed as a fraction. The top number refers to the distance you stand from the chart or 20 feet. The bottom number indicates the distance at which a person with normal eyesight could read the same line you correctly read. Both eyes remain open during examination; no squinting or straining
  3. abnormally large red blood cells (MCV over 95 fL) size category used to classify anemia
  4. blood test to determine the percentage of red blood cells within the volume of blood, performed by measuring after centrifuging to separate elements, average of the 2 measures from 2 separate microhematocrit tubes, used to screen for anemia F-36-45% M-42-52%
  5. EDTA/ethylenediaminetetra acetic acid citrates, heparin, oxalates

5 True/False questions

  1. nutritional anemia may show normal _______________ but low HgBmicrocytosis (MCV below 80 fL) RBC count, hemoglobin and hematocrit will be used to diagnose iron deficiency anemia. (cells will be hypochromic and microcytic under microscope) macrocytosis (MCV above 95 fL) may be caused by a B12 or folic acid deficiency


  2. potassium: K testmineral To assist in diagnosis of acid-base-water balance


  3. irrigating earsnitrogenous waste from muscle metabolism excreted in urine


  4. blood smear slide viewiew at feathered end of smear where blood is thinnest; use oil immersion lens and oil to view under microscope, count in high powered fields (HPF) moving from one to another in a serpentine motion. Use cell counter as manually counting. Microscope used to examine cell morphology.


  5. Hemoglobin (substance)HgB Test measures concentration of the hemoglobin in the blood. Hemoglobin levels are a rough measure of the oxygen-carrying capacity of the blood. Normal ranges: W:12-16 g/dL; M:15-17 g/dL Anemia is detected with Hgb measurement
