質問 # 21
Which of the following terms means a decrease in white blood cells?
正解：A
解説：
Leukopenia means a decreased number of white blood cells. "Leuko-" refers to white blood cells, and "-penia" means deficiency or decrease. Leukocytosis means an increased white blood cell count and is often associated with infection, inflammation, stress response, or hematologic disorders. Thrombocytopenia means a decreased platelet count, which can increase bleeding risk after venipuncture. Erythrocytosis means an increased red blood cell count. This terminology matters to phlebotomy because laboratory orders and patient conditions often use hematologic language. The phlebotomist does not diagnose these conditions, but understanding terms helps the technician anticipate safety concerns and specimen requirements. For example, thrombocytopenia may require longer pressure after collection, while leukopenia may be associated with immunocompromised status and strict infection-control awareness. A CBC is the common test used to evaluate red cells, white cells, hemoglobin, hematocrit, and platelets. Reference topics: Phlebotomy Fundamentals; medical terminology; hematology; CBC components; blood cell disorders.
質問 # 22
Which of the following actions should a phlebotomist take before palpating a vein?
正解：A
解説：
The phlebotomist should put on gloves before palpating a vein. Gloves are required because the phlebotomist is preparing for an invasive procedure with potential blood exposure. Palpation helps assess vein size, depth, direction, resilience, and suitability, but it must occur after hand hygiene and glove application. Removing the needle cap before site selection is unsafe because it exposes the needle unnecessarily and increases needlestick risk. Labeling collection tubes before collection is improper because tubes must be labeled after collection in the presence of the patient to prevent misidentification. Asking the patient to bend the arm is not appropriate for vein palpation and is especially unsafe after needle removal because bending the arm can cause hematoma formation. The correct sequence is patient identification, hand hygiene, gloves, position patient, apply tourniquet, select/palpate vein, release/reapply tourniquet as needed, clean site, allow antiseptic to dry, anchor, and perform venipuncture. Reference topics: Routine Blood Collections; glove use; vein palpation; venipuncture sequence; patient safety.
質問 # 23
A phlebotomist must recollect a blood sample after the initial sample was rejected by the laboratory. Which of the following factors might have caused the sample to be rejected?
正解：D
解説：
An underfilled collection tube is a common reason for laboratory rejection because many tests require a specific blood-to-additive ratio. This is especially critical for coagulation specimens, where insufficient blood relative to anticoagulant can falsely prolong clotting results. Underfilling can also produce inadequate specimen volume for testing, repeat analysis, or instrument requirements. A hematoma at the puncture site is a patient complication and may indicate procedural difficulty, but it does not automatically require specimen rejection unless it affected specimen quality. Use of a multiple-sample needle is a standard venipuncture method and is not a rejection criterion by itself. The cephalic vein is an acceptable antecubital vein when selected appropriately, so using it does not invalidate the specimen. Processing accuracy begins at collection: correct tube, correct volume, correct mixing, correct labeling, and correct transport. The NHA CPT outline identifies preanalytical errors, minimum and maximum volume requirements, fill levels and ratios, maintaining specimen integrity, and recollection as core processing and collection competencies. Reference topics: Processing Specimens; preanalytical errors; tube fill level; specimen rejection and recollection.
質問 # 24
Which of the following actions should a phlebotomist take when obtaining a throat culture?
正解：C
解説：
When obtaining a throat culture, the phlebotomist should swab the tonsillar area and the back of the throat because these are the clinically relevant sites for detecting organisms associated with pharyngitis, such as group A Streptococcus. The swab should avoid the tongue, cheeks, teeth, and lips because contact with those surfaces can contaminate the specimen with normal oral flora and reduce diagnostic value. Swabbing the buccal areas collects cheek-cell or oral flora material, not a proper throat specimen. Swabbing visible mucus in the oral cavity is unreliable because mucus may not represent the infected pharyngeal area. Leaving the swab in the sublingual area is inappropriate because the area under the tongue is not the target site for a throat culture. Correct technique includes explaining the procedure, positioning the patient, using a tongue depressor if needed, quickly swabbing the tonsillar pillars and posterior pharynx, placing the swab in the correct transport medium, and labeling the specimen accurately. Reference topics: Special Collections; non-blood specimen collection; throat culture technique; specimen integrity; patient instructions.
質問 # 25
Which of the following is the purpose of centrifuging a blood specimen?
正解：C
解説：
The purpose of centrifuging a blood specimen is to separate specimen components. Centrifugation uses force to separate cells from serum or plasma based on density. In serum separator tubes, centrifugation separates serum from the clot after the specimen has fully clotted. In plasma separator tubes, centrifugation separates plasma from blood cells in the presence of anticoagulant. It does not disinfect the specimen; blood specimens must still be treated as potentially infectious. It does not activate tube additives; additives function through mixing by gentle inversion after collection. It also does not increase specimen volume. Improper centrifugation can damage specimens. Centrifuging too soon, too long, too fast, or at the wrong temperature can cause hemolysis, fibrin formation, poor separation, or analyte instability. The phlebotomist must follow manufacturer and facility instructions for clotting time, centrifuge speed, duration, balancing, and specimen removal. Reference topics: Processing Specimens; centrifugation; serum and plasma separation; specimen integrity; equipment operation.
