질문 # 33
A phlebotomist is collecting blood from a patient with small fragile veins. Which of the following devices is most appropriate?
정답：C
설명：
A winged infusion set is most appropriate for a patient with small fragile veins. Butterfly devices provide better control, flexible tubing, and a shallower insertion angle, making them useful for hand veins, pediatric patients, geriatric patients, or difficult venous access. A 16-gauge needle is too large for routine diagnostic venipuncture and would likely damage fragile veins. A blood culture bottle adapter is used for blood culture collection but does not solve the problem of fragile vein access by itself. A lancet is used for dermal puncture, not venous collection, and may not provide the volume or specimen type required for ordered venipuncture tests. When using a winged infusion set, the phlebotomist should anchor the vein carefully, insert bevel up at a low angle, stabilize the device, monitor for infiltration, and activate the safety mechanism immediately after withdrawal. Equipment selection is a clinical safety decision, not a convenience choice. Reference topics: Routine Blood Collections; winged infusion set; fragile veins; equipment selection; venipuncture technique.
질문 # 34
Which of the following types of consent provides a patient with information about the methods, risks, and consequences of a procedure?
정답：B
설명：
Informed consent means the patient receives enough information to understand the nature of the procedure, including the method, purpose, risks, benefits, alternatives, and possible consequences, before agreeing. Therefore, informed consent is the correct answer. Expressed consent means the patient clearly agrees, either verbally or in writing, but the term does not by itself prove that the patient received a full explanation of risks and consequences. Implied consent occurs through the patient's actions, such as extending an arm for venipuncture after identification and explanation. Verbal consent is simply the spoken form of agreement and may be expressed, but again it does not specifically define the full disclosure requirement. In phlebotomy, routine blood collection often proceeds with implied or expressed consent after proper identification and explanation, but higher-risk or special procedures may require more formal informed consent depending on policy. The NHA CPT outline includes receiving implied, informed, or expressed consent and understanding the components required for consent. Reference topics: Patient Preparation; patient rights; consent types; communication before collection.
질문 # 35
Which of the following should a phlebotomist verify for quality control protocol prior to using vacuum tubes?
정답：A
설명：
Before using evacuated vacuum tubes, the phlebotomist must verify the expiration date. Expired tubes can lose vacuum, produce inadequate draw volume, compromise the blood-to-additive ratio, or contain additives that no longer perform as intended. This can directly affect specimen integrity and may lead to inaccurate results or specimen rejection. Needle integrity is also important, but it applies to needle inspection rather than vacuum tube quality control. Visible additive may be observed in some tubes, but not all additives are easily visible, and visibility alone does not confirm the tube is acceptable for use. Name on label is not checked before using an unused tube because patient labeling occurs after collection according to facility policy and positive patient identification requirements. Tube quality control includes inspecting tubes for cracks, contamination, expired dates, defective stoppers, and compromised vacuum. NHA CPT routine collection content specifically includes selecting and assembling equipment, verifying equipment quality, checking expiration dates, and inspecting evacuated tubes required for laboratory testing. Reference topics: Routine Blood Collections; evacuated tube quality control; expiration dates; equipment inspection.
질문 # 36
A phlebotomist notices that a serum separator tube has not clotted before centrifugation. Which of the following actions should the phlebotomist take?
정답：A
설명：
The phlebotomist should allow the serum separator tube to clot completely before centrifugation. Serum specimens require clot formation before centrifugation so the liquid serum can separate properly from the clot. Centrifuging before clotting is complete can cause fibrin strands, incomplete separation, instrument issues, and possible specimen rejection. Shaking the tube vigorously is incorrect because it can hemolyze the specimen and disrupt cellular integrity. Transferring the specimen into a plasma tube is unsafe and invalid because the specimen was not collected with the correct anticoagulant at the correct blood-to-additive ratio. Proper processing means respecting the requirements of the tube collected: serum tubes must clot for the required time, additive tubes must be gently inverted, and specimens must be centrifuged according to time, speed, and temperature requirements. This item tests processing discipline, not speed. A phlebotomist must protect specimen integrity from collection through transport and processing. Reference topics: Processing Specimens; serum separation; clotting time; centrifugation; specimen rejection.
질문 # 37
Which of the following is the purpose of centrifuging a blood specimen?
정답：A
설명：
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.
