질문 # 64
A phlebotomist notices that a serum separator tube has not clotted before centrifugation. Which of the following actions should the phlebotomist take?
정답：D
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 # 65
Which of the following additives is commonly found in a gray-top tube used for glucose testing?
정답：B
설명：
Sodium fluoride is commonly found in gray-top tubes used for glucose testing. Sodium fluoride inhibits glycolysis, which helps preserve glucose concentration after collection by slowing cellular glucose consumption. Many gray-top tubes also contain potassium oxalate as an anticoagulant. Sodium citrate is found in light-blue tubes used for coagulation studies because it binds calcium reversibly. EDTA is found in lavender-top tubes and is commonly used for hematology testing such as CBC. SPS is sodium polyanethol sulfonate, an additive used in blood culture bottles or yellow SPS tubes because it supports organism recovery by reducing certain inhibitory effects. Tube additives are not trivia; they determine specimen type and test validity. A glucose specimen collected in the wrong tube or processed late may produce inaccurate results because cells continue metabolizing glucose after collection. The phlebotomist must match test, tube, additive, order of draw, fill volume, and handling requirements. Reference topics: Special Collections; glucose testing; gray-top tube; sodium fluoride; additive function.
질문 # 66
A patient refuses a blood draw after the phlebotomist explains the procedure. Which of the following actions should the phlebotomist take?
정답：B
설명：
The phlebotomist should notify the nurse or provider according to facility policy. A competent adult patient has the right to refuse a blood draw, even when the test is ordered. Proceeding against the patient's refusal is unethical and can constitute battery. Asking a family member to pressure the patient is inappropriate because consent must come from the patient or legally authorized representative when applicable, not from coercion. Using a smaller needle does not address refusal unless the patient specifically refused because of needle size and then gives consent after discussion. The phlebotomist should remain professional, clarify the patient's concern within scope, avoid arguing, document or report the refusal as required, and allow authorized clinical personnel to follow up. This question tests patient rights, consent, communication, and scope of practice. Phlebotomy is invasive, so consent is not optional. The technician's authority ends where patient refusal begins unless a specific emergency or legal policy applies through authorized medical personnel. Reference topics: Patient Preparation; patient refusal; consent; patient rights; communication; documentation.
질문 # 67
A phlebotomist enters a patient's room and finds the patient motionless and cyanotic. Which of the following actions should the phlebotomist take?
정답：D
설명：
The first action is to assess responsiveness by speaking loudly and directly to the patient, such as asking whether they are okay. A motionless, cyanotic patient may be in respiratory or cardiac arrest, but the phlebotomist must follow the emergency response sequence rather than jumping to airway maneuvers, rescue breaths, or AED use before confirming responsiveness and activating help according to facility protocol. The head-tilt/chin-lift maneuver is an airway-opening step, but it follows initial responsiveness assessment and emergency activation. Rescue breaths are not the first step and are performed only within the appropriate CPR sequence and training level. Applying an AED is appropriate when cardiac arrest is suspected and the emergency response process has been initiated, but the first immediate action from the options is responsiveness assessment. NHA CPT safety content includes recognizing emergencies, initiating first aid, responding to codes, and CPR-related guidelines. Reference topics: Safety and Compliance; emergency recognition; CPR sequence; first aid response.
질문 # 68
Which of the following veins is usually the last choice for antecubital venipuncture?
정답：C
설명：
The basilic vein is usually the last choice for antecubital venipuncture. The median cubital vein is preferred because it is typically large, well anchored, superficial, and less likely to roll. The cephalic vein is commonly the second choice when the median cubital is unavailable. The basilic vein is used cautiously because it lies closer to the brachial artery and median nerve, creating greater risk if the needle is inserted too deeply or inaccurately. The dorsal metacarpal veins are hand veins, not antecubital veins, and may be used when antecubital access is unavailable, often with a butterfly needle and shallow angle. This question tests anatomical risk control. A phlebotomist must not simply pick the most visible vein; they must evaluate vein safety, depth, direction, resilience, patient history, and contraindications such as IV sites, edema, burns, scars, hematomas, fistulas, and mastectomy restrictions. Proper site selection reduces pain, nerve injury, arterial puncture, hematoma, and recollection risk. Reference topics: Routine Blood Collections; antecubital anatomy; vein selection; basilic vein risk.
