Complete BOC: ASCP Test Prep

Complete BOC: ASCP Test Prep 1) After receiving a 24 hr. urine for quantitative total protein analysis the technician must first: a. subculture the urine for bacteria b. add the appropriate preservative c. screen for albumin using a dipstick d. measure the total volume - d (measure the total volume) 1) Following overnight fasting, hypoglycemia in adults is defined as a glucose of: a. 70 mg/dL (3.9 mmol/L) b. 60 mg/dL (3.3mmol/L) c. 55 mg/dL (3.0mmol/L) d. 45mg/dL (2.5mmol/L) - d (Diagnosis of hypoglycemia in adults.) 1) Proper media for culture of a urethral discharge from a man include: a. sheep blood and phenylethyl alcohol agars b. eosin methylene blue and sheep blood agars c. thioglycollate broth and chocolate agar d. chocolate agar and modified Thayer Martin agar - d (Chocolate agar and chocolate agar- based selective media should be used for recovery of Neisseria gonorrhoeae from urethral discharge. Chocolate agar provides the nutrients required by N gonorrhoeae and selective media contains antimicrobial agents that inhibits other organisms and permits recovery of pathogenic Neisseria.) 1) The light-colored zone adjacent to the nucleus in a plasmacyte is the: a. ribosome b. chromatin c. mitochondria d. Golgi area - d (Morphological identifiable perinuclear halo.) 1) The minimum Hgb concentration in a fingerstick from a male blood donor is: a. 12.0 g/dL (120 g/L) b. 12.5 g/dL (125 g/L) c. 13.5 g/dL (135 g/L) d. 15.0 g/dL (150 g/L) - b (All donors, regardless of sex, require a minimum hemoglobin of 12.5 g/dL [125 g/L]. The value must not be performed on an earlobe stick.) 2) A sheep blood agar plate inoculated with 0.001 mL of urine grows 70 colonies of Staphylococcus aureus. How many colony forming units per mL of urine should be reported: a. 70 b. 700 c. 7000 d. 70000 - d (When 0.001 mL of urine is plated, the growth of one colony is equivalent to 1000 CPU/mL. Thus 70 colonies is 70,000 CPU/mL.) 2) False results in the urobilinogen testing may occur if the urine specimen is: a. exposed to light b. adjusted to a neutral pH c. cooled to room temp d. collected in a nonsterile container - a (exposed to light) 2) The following results are from a 21-year-old patient with a back injury who appears otherwise healthy: - whole blood glucose = 77 mg/dL (4.2 mmol/L} - serum glucose = 88 mg/dL (4.8 mmol/L) - CSF glucose = 56 mg/dL (3.1 mmol/L) The best interpretation of these results is that: a. the whole blood and serum values are expected but the CSF value is elevated b. the whole blood glucose value should be higher than the serum value c. all values are consistent with a normal healthy individual d. the serum and whole blood values should be identical - c (Body fluid glucose reference ranges.) 2) Which action by the phlebotomist will comply with the College of American Pathologists (CAP) Patient Safety Goal "to improve patient and sample identification at the time of specimen collection" and The Joint Commission Patient Safety Goal to "improve the accuracy of patient identification"? a. match the name and room number on the patient's ID bracelet to the name and room number on the preprinted collection label b. match the name and medical record number on the patient's ID bracelet to the name and medical record number on the preprinted collection label c. verify patient information by stating the patient's name when approaching the patient d. label the collection tubes prior to the blood draw at the patient's bedside - b (The Joint Commission requires 2 patient identifiers when providing care, treatment, or service.) 3) A clean catch urine is submitted to laboratory for routine urinalysis and culture. The routine urinalysis is done first, and 3 hrs. later, the specimen is sent to the microbiology department for culture. The specimen should: a. be centrifuged, and the supernatant culture b. be rejected due to the time delay c. not be cultured if no bacteria are seen d. be processed for culture only if the nitrate is positive - b (be rejected due to the time delay) 3) A swab and requisition are received in the microbiology laboratory with the following information: The laboratory receiving clerk notes a discrepancy between the patient identifiers on the requisition and the specimen label, and questions the emergency department nurse MB. This is the fourth specimen this week that has had a specimen discrepancy. What action is the most appropriate to prevent this type of error in the future? a. correct the error in the laboratory when the nurse communicates the appropriate patient name b. ask nurse MB to correct discrepancy and read the procedure for specimen labeling
