질문 # 24
A phlebotomist is collecting a blood culture from a 6-month-old infant who has no known allergies. Which of the following disinfectants should the phlebotomist use?
정답：A
설명：
Chlorhexidine gluconate is the best answer for blood culture skin antisepsis in this 6-month-old infant with no known allergies. Blood cultures require stricter skin disinfection than routine venipuncture because contamination can produce false-positive culture results, unnecessary antibiotics, repeat testing, and delayed diagnosis. Sodium polyanethol sulfonate is not a skin disinfectant; it is an anticoagulant/additive used in blood culture media to support organism recovery. Sodium hypochlorite is a bleach-type disinfectant used for environmental decontamination, not patient skin preparation for venipuncture. Hydrogen peroxide is not the standard blood culture skin antiseptic. Chlorhexidine is widely used for effective skin antisepsis, and CDC guidance recognizes chlorhexidine-containing agents in healthcare infection-control contexts when age, skin maturity, and clinical risk are considered. For collection technique, the phlebotomist should cleanse the site properly, allow the antiseptic to dry, avoid repalpating unless sterile technique is used, collect adequate volume, and label/document accurately. Reference topics: Special Collections; blood culture collection; pediatric skin preparation; contamination prevention.
질문 # 25
Which of the following types of medication is an indication for an INR draw?
정답：C
질문 # 26
Which of the following is a possible complication of venipuncture collection for a patient who has been on warfarin therapy?
정답：A
설명：
Prolonged bleeding is the expected complication for a patient on warfarin therapy. Warfarin is an anticoagulant, meaning it interferes with normal clot formation and can increase bleeding time after venipuncture. The phlebotomist should be alert for delayed hemostasis, apply firm pressure after needle removal, avoid having the patient bend the arm sharply, and confirm that bleeding has stopped before applying a bandage and leaving the patient. Blood clotting is the opposite of the expected medication effect. Hemostasis is the normal stopping of bleeding, not a complication. Petechiae can occur from tourniquet pressure, fragile capillaries, or platelet-related issues, but in this question the medication-specific risk is prolonged bleeding. Proper technique reduces complications: release the tourniquet, withdraw the needle smoothly, activate the safety device, apply pressure, and monitor the puncture site. Reference topics: Routine Blood Collections; post-procedure care; anticoagulant therapy; bleeding complications; hemostasis; patient observation. NHA includes routine venipuncture complications and post-collection care within the CPT test plan.
질문 # 27
Which of the following specimens should be collected before antibiotics are administered when ordered for suspected bloodstream infection?
정답：A
설명：
Blood cultures should be collected before antibiotics are administered when ordered for suspected bloodstream infection. Antibiotics can reduce or inhibit microbial growth in the specimen, potentially producing false-negative results. Blood cultures are used to detect bacteria or fungi in the bloodstream and require careful timing, strict antisepsis, adequate volume, and correct bottle handling. A lipid panel, hemoglobin A1c, and electrolyte panel do not depend on organism recovery and are not the priority before antibiotic therapy in this context. The phlebotomist must follow facility policy for collection order, number of sets, collection sites, bottle order, skin preparation, and documentation. If antibiotics have already been started, the phlebotomist should not cancel the test independently; they should collect according to order and document or communicate relevant timing if required. Blood culture contamination is a serious quality problem, but delayed collection after antibiotic administration can also reduce diagnostic value. Reference topics: Special Collections; blood cultures; timing before antibiotics; bloodstream infection; aseptic technique.
질문 # 28
A phlebotomist is preparing to perform venipuncture on a patient who has had a right-sided mastectomy. Which of the following collection sites should the phlebotomist select?
정답：A
설명：
The phlebotomist should select the left antecubital area because the patient has had a right-sided mastectomy. Venipuncture should generally be avoided on the side of a mastectomy due to the risk of impaired lymphatic drainage, lymphedema, infection, and delayed healing. The right cephalic and right basilic veins are on the affected side and should not be used unless a provider specifically authorizes collection from that side. The left femoral artery is not an appropriate routine phlebotomy site and arterial collection is outside standard venipuncture practice unless performed under specialized authorization and scope. The left antecubital area is the safest option listed because it uses the unaffected arm and provides standard venipuncture access. The technician should still assess vein suitability, avoid sites with IVs, edema, scarring, hematoma, or infection, and follow facility policy if no acceptable site is available. This question tests contraindicated sites and safe site selection, not simply vein-name recall. Reference topics: Routine Blood Collections; mastectomy precautions; venipuncture site selection; contraindicated sites; patient safety.
