| a patient who is not allowed to have food or water for a specified time is classified as | NPO |
| a phlebotomist who enters a patients room to collect a fasting specimen and finds the patient eating breakfast should | notify the nursing station |

| lipemic serum appears | cloudy due to the presence of fat |
| collection of a cardiac risk profile from an outpatient at 1600 may result in | increased triglycerides |
| to monitor changes in a patients hemoglobin level, you may be requested to collect | specimens at specific times |
| a GTT is performed to diagnose or evaluate | hypoglycemia and diabetes mellitus |
| plasma cortisol levels are scheduled to be drawn between 0800 and 1000 because | cortisol exhibits diurnal variation |
| peak and trough levels are collected to monitor | therapeutic drug levels |
| a postprandial blood specimen should be collected | after the patient has eaten |
| the timing for a GTT begins | when the patient finishes drinking the glucose |
| a trough level is drawn | prior to administering meds |
| the term diurnal variation is associated with | timed collections |
| the number od specimens collected form a patient recieving a 2 hour postprandial glucose test is | 2 |
| the specimen collected during the GTT after the patient drinks the glucose will be analyzed at the end of the test. the specimens should be collected in | gray stopper tubes |
| all of the following should be included on a peak and trough level requisition form except | name of the person giving the meds |
| the fasting specimen for a GTT is drawn at 0700 and the patient finishes drinking the glucose at 0745. the correct time to draw the 1 hour specimen is | 0845 |
| a phebotomist who cant locate the patient on whom a cortisol level is scheduled for collection at 1000 should | return the requsition to the nursing station for rescheduling |

| after collection blood cultures are delivered to | microbiology |
| some blood culture collection systems contain a resin to | inactivate antibiotics |
| the word meaning an abnormal accumulation of fluid in the tissues is | edema |
| if a suitable vein is not located in the left arm you should | check the right arm |
| incorrect collection of blood from a patient who has had a mastectomy can result in all of the following except the | samples being affected by chemotherapy |
| fistulas are seen in patients who are | recieving dialysis |
| collection of specimens from leg veins is not recommended in all of the following except | a patient with multiple fractures |
| dermal puncture is preferred over venipuncture in infants because | restraining a child can cause injury, superficial veins may not be large enough, collection from deep veins is dangerous |
| collection of a sufficient amount of blood by dermal puncture is most difficult from | severely dehydrated patients |
| which of these complications not associated with deep vein puncture in infants | collapsing of superficial veins |
| collection of a CBC by dermal puntcure is most likely to be requested for a patient | recieving chemotherapy |
| blood collected by dermal puntcure most closely resembles | arterial blood |
| the major vascular area of the skin is located in the | dermal-subcutaneous juncture |
| collection of excessive blood from a premature infant could cause | anemia |

| amber colored microcontainer tubes are used to collect specimens for | bilirubin |
| a physician questions the low bilirubin result on a jaundiced baby. this discrepancy may be due to | exposing the specimen to the bililight |
| the high RBC counts normally seen in newborns may cause | decreased glucose levels |
| newborns who appear jaundiced | have increased bilirubin levels |
| a bilirubin collected from a jaundiced infant has a normal result. this result | may indicate the specimen was collected under the bililight |
