RPT Practice Test (AMT Certification)

RPT Practice Test (AMT Certification) The process by which complex substances are broken down into simple substances is called - Catabolism When a patient develops syncope during a venipuncture, the phlebotomist should first: - remove the tourniquet and needle and then call for help. Which substance has a higher concentration in capillary blood than in venous blood? - Glucose is normally higher in capillary blood compared to venous blood and Potassium, Calcium and Total Protein are normally lower If a patient is critical or an antibiotic needs to be given right away, and two blood culture sets are collected - When more than one set of blood cultures are ordered to be collected at the same time, the second set should be obtained from a separately prepared site on the opposite arm if possible When performing a capillary blood collection, the first blood drop is wiped away because - the first drop typically has more tissue fluid Why is it necessary to wipe the first drop of blood away when performing a capillary procedure? - to eliminate excess tissue fluid;To reduce interstitial fluid contamination The color-coded tube that is most frequently associated with coagulation tests is - light blue How far above the venipuncture site should the tourniquet be wrapped around the arm? - 3 to 4 inches How long should a tourniquet be placed around a patient's arm? - No more than one minute When is a phlebotomist allowed to perform a venipuncture on an ankle vein? - When all other options have been exhausted and the physician has given approval Prior to bandaging the puncture site the phlebotomist should - examine the site for bleeding During venipuncture, a hematoma may result from which of the following? - Needle bevel is partially inserted into a vein Alcohol should be allowed to dry completely prior to skin puncture to - prevent lysis of red blood cells When palpating, a vein having which one of the following characteristics would be most appropriate to select for venipuncture? - Bouncy Following venipuncture, which of the following should be applied to the venipuncture site? - Clean, sterile gauze pad What is the preferred method for infant blood collection? - Capillary Which of the following actions could cause the formation of a hematoma? - The needle penetrates all the way through the vein what is the most critically affected analyte in a hemolyzed specimen - Potassium The heel is the recommended site for collection of capillary puncture specimens on infants and the phlebotomist is going to stick in the posterior curvature of the heel. Is this correct? - No the medial plantar surface of the heel is the best site to prevent possible bone damage You have properly prepared the antecubital venipuncture site, you have the corrrect collection device and enter the vein at a 20 degree angle. Is this the proper angle of insertion? - No, 30 degrees is the correct angle for the needle to be inserted into the skin If blood begins to flow and then stops when an evacuated tube is pushed into the needle the most likely cause is the - bevel of
