Complete all three parts of the case study and answer all the questions CaseCASE STUDY 6-1: CIRCULATORY SYSTEMDISORDERS AND DIAGNOSTIC TESTSA phlebotomist receives a request to collect specimensfor STAT electrolytes, CK, and AST on a patient with apossible MI. When the phlebotomist arrives to draw thespecimen, a physician is with the patient and the patientis explaining that he had been feeling extreme anginalpains for almost an hour now. The physician tells thephlebotomist to go ahead and draw the specimen. Thepatient has an IV in the left arm near the wrist. There is asphygmomanometer around the upper right arm.CASE STUDY 6-2: CIRCULATORY SYSTEMDISORDERS, DIAGNOSTIC TESTS, AND VEINSELECTIONA phlebotomist receives a request to collect a specimen fora PT and D-dimer on a patient. The phlebotomist remem-bers drawing the patient in the ER when he was complain-ing of leg pain. Because the patient was a difficult draw,the phlebotomist wanted to draw from an ankle vein, butthe physician would not give permission. The patient wassubsequently diagnosed with DVT. When the phlebotomistreceived the next request on this patient, he still couldn'tfind a good vein in the AC area, but he noticed that thepatient had a large vein on the underside of the wrist. BeforeQuestions1. What do the abbreviations CK and AST mean?2. Which circulatory system structure is being evaluated bythe ordered tests?3. What does the abbreviation MI stand for, and what doesmean in nonmedical terms?4. What does angina have to do with the patient's possiblediagnosis of MI?5. What is a sphygmomanometer, and can the phlebotomistuse that arm to draw blood?the phlebotomist could collect from the wrist area, he wascalled to a STAT in the ER.Questions1. Should the phlebotomist draw from the vein on theunderside of the wrist? Why or why not?2. What do PT and DVT mean?3. Which body process is being evaluated by the requestedtests?4. What type of specimen is required: serum, plasma, orwhole blood?5. Give a reason for your selection of specimen type.CASE STUDY 6-3: CIRCULATORY SYSTEMDISORDERS, DIAGNOSTIC TESTS, AND VEINSELECTIONA phlebotomist is called to the ER to draw a STAT hct, hgb,and plt ct on a young girl who appears extremely paleand very close to being unconscious. While checkingfor a good puncture site, the phlebotomist notes the "M"pattern of veins on both arms but really can't feel theveins that well. After reapplying the tourniquet and mak-ing it a bit tighter, the vein in the middle of the AC onthe right arm becomes palpable, but when entered, theblood slowly drips into the tube. After the tube is filled,the phlebotomist applies pressure to the puncture siteand makes a point of holding it longer than usual beforeapplying a new gauze and tape. While waiting, the phle-botomist overhears the nurse say that the patient's BPis 80/50, and her pulse is weak. The mother says herdaughter had a nosebleed that lasted almost all night.Ready to go back to the laboratory, the phlebotomist checksthe puncture site again and sees that the bleeding has notstopped. The ER tech continues to put pressure on the site asthe phlebotomist leaves.Questions1. From which vein did the phlebotomist collect the bloodspecimens for the tests?2. What do the abbreviations of the three tests that wereordered mean?3. Which body processes or systems are being evaluated bythe requested tests?4. Why did the blood enter so slowly into the evacuatedtube?5. Why did the applied pressure and length of time not stopblood from flowing at the puncture site?

In this case study, we investigate the situation of a phlebotomist called to collect blood specimens…

QUESTION 1 Match each description to the correct study design. Study designs may be used more than once. ◆ Incidence data is not available with this study design, so an odds ratio is an appropriate measure of association to calculate. ◆ This study design allows for the evaluation of multiple outcomes. ◆ The temporal sequence between the exposure and outcome is clear for this study design; therefore, incidence data is available and a risk ratio can be calculated. ◆ With this study design, exposure status is assessed, and then participants are followed up over time to see who develops the outcome. ◆ Recall bias is a common issue with this study design because exposure information is collected from the past.
