질문 # 52
Which of the following actions can cause hemolysis during venipuncture?
정답：C
설명：
Using a needle with a gauge that is too small can cause hemolysis. A small-bore needle can create excessive mechanical force as blood passes through the lumen, damaging red blood cells and releasing intracellular contents into serum or plasma. Hemolysis can alter test results, especially potassium, lactate dehydrogenase, and other analytes affected by red-cell rupture. Allowing alcohol to dry before puncture is correct practice because it reduces stinging and helps prevent contamination. Releasing the tourniquet before needle removal is also correct because it reduces pressure and supports safer needle withdrawal. Mixing additive tubes by gentle inversion is required; the danger occurs when tubes are shaken vigorously. Additional hemolysis causes include probing, drawing through a hematoma, forcing blood from a syringe into a tube, rough transport, incorrect centrifugation, and delayed processing. A phlebotomist must choose equipment appropriate to the patient's vein while maintaining specimen quality. Reference topics: Routine Blood Collections; hemolysis; needle gauge selection; specimen integrity; preanalytical error.
질문 # 53
Which of the following findings should cause a phlebotomist to delay collection and seek assistance?
정답：B
설명：
A patient who is diaphoretic and says they feel faint requires the phlebotomist to delay collection and seek assistance. Diaphoresis, dizziness, pallor, nausea, and weakness can signal an impending syncopal episode. Continuing with venipuncture in this condition increases the risk of falls, needle injury, hematoma, and patient harm. Confirming date of birth is normal patient identification. Asking which arm will be used is a reasonable patient question and does not require delay. A visible median cubital vein is generally favorable for routine venipuncture. The phlebotomist should position the patient safely, preferably reclining or lying down if fainting risk is present, notify appropriate personnel, and proceed only when safe according to facility policy. If symptoms occur during a draw, the technician should remove the tourniquet and needle when safe, activate the safety device, call for help, and monitor the patient. Reference topics: Patient Preparation; syncope warning signs; patient assessment; collection delay; emergency response.
질문 # 54
Which of the following additives is commonly found in a gray-top tube used for glucose testing?
정답：A
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 # 55
Which of the following transmission-based precautions should a phlebotomist follow when performing collections for a patient who has a Clostridium difficile infection?
정답：A
설명：
Clostridium difficile infection requires contact precautions because the organism is transmitted primarily by the fecal-oral route through contaminated hands, surfaces, equipment, and patient-care environments. A phlebotomist entering the room must follow posted isolation instructions, use appropriate PPE, and perform meticulous hand hygiene. For C. difficile, soap-and-water handwashing is especially important because alcohol-based hand rubs do not reliably destroy spores. Airborne precautions are used for diseases transmitted by small droplet nuclei, such as tuberculosis. Droplet precautions are used for organisms spread through respiratory droplets, such as influenza or pertussis. Reverse isolation is used to protect severely immunocompromised patients from external contamination, not to protect staff and other patients from C. difficile. Contact precautions directly address the transmission route. The phlebotomist should also avoid bringing unnecessary supplies into the room, disinfect reusable equipment according to policy, and prevent cross-contamination during specimen handling. Reference topics: Safety and Compliance; infection control; transmission-based precautions; PPE; isolation procedures; hand hygiene.
질문 # 56
A patient refuses a blood draw after the phlebotomist explains the procedure. Which of the following actions should the phlebotomist take?
정답：D
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.
