質問 # 121
At which of the following angles should a phlebotomist insert an antecubital venipuncture needle?
正解：A
解説：
For antecubital venipuncture, the needle is inserted bevel up at approximately a 15° to 30° angle, with 30° commonly used as the upper accepted standard for routine venous access. From the options provided, 30° is the best answer. A 10° angle is usually too shallow for antecubital venipuncture and may cause the needle to skim the skin surface or fail to enter the vein lumen. A 45° angle is too steep and increases the risk of passing through the vein, causing hematoma, pain, or arterial/nerve injury depending on site depth and anatomy. A 25° angle can be clinically workable in some routine venipunctures, but this item is asking for the standard recognized insertion angle, and 30° is the expected test answer. Proper angle must be combined with vein anchoring, bevel-up orientation, stable equipment control, and avoidance of excessive probing. The NHA CPT outline specifically includes needle insertion, angle of needle insertion and withdrawal, and routine venipuncture technique. Reference topics: Routine Blood Collections; antecubital venipuncture; angle of needle insertion; needle withdrawal and safety.
質問 # 122
A phlebotomist is collecting from a patient under droplet precautions. Which of the following PPE is most directly indicated?
正解：C
解説：
A surgical mask is most directly indicated for droplet precautions. Droplet precautions are used for organisms transmitted through respiratory droplets generated by coughing, sneezing, or talking. The mask helps protect the phlebotomist's nose and mouth from exposure at close range. A lead apron is used for radiation protection and has no role in droplet isolation. A sterile gown alone does not protect the respiratory mucosa and is not the primary droplet precaution. Shoe covers alone do not address droplet transmission. Depending on facility signage and procedure risk, additional PPE such as eye protection, gown, or gloves may be required, but from the options given, a surgical mask is the key droplet precaution. The phlebotomist should check isolation signs before entering, bring only necessary supplies, perform hand hygiene, wear PPE correctly, and remove PPE safely before leaving. This item tests transmission-based precaution matching: contact, droplet, airborne, and protective isolation are not interchangeable. Reference topics: Safety and Compliance; droplet precautions; PPE; isolation signage; infection control.
質問 # 123
Which of the following practices violates standard precautions?
正解：D
解説：
Reusing a tourniquet visibly contaminated with blood violates standard precautions. Any reusable equipment contaminated with blood must be cleaned and disinfected according to facility policy, and single-use items must be discarded. Blood is treated as potentially infectious regardless of the patient's diagnosis or appearance. Wearing gloves during venipuncture is correct practice. Treating all blood as potentially infectious is the core principle of standard precautions. Washing hands after glove removal is also required because gloves can have microscopic defects or hands can become contaminated during removal. A contaminated tourniquet can transfer bloodborne pathogens or other organisms to patients, staff, and surfaces. Phlebotomists should inspect equipment before use, avoid placing supplies on contaminated surfaces, use disposable tourniquets when required, and disinfect reusable items appropriately. Infection-control failures often occur through routine shortcuts, not dramatic emergencies. This question tests whether the technician understands standard precautions as everyday behavior, not just PPE vocabulary. Reference topics: Safety and Compliance; standard precautions; reusable equipment; blood contamination; infection prevention.
質問 # 124
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?
正解：D
解説：
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.
質問 # 125
Which of the following actions should a phlebotomist take immediately after blood splashes into their eye?
正解：C
解説：
The phlebotomist should immediately flush the eye with water at an eyewash station. Blood exposure to mucous membranes is a bloodborne pathogen exposure incident and requires immediate decontamination before administrative steps. Wiping the eye with gauze is inadequate and can irritate tissue or fail to remove infectious material. Continuing patient collections delays treatment and increases occupational risk. Applying antibiotic ointment is outside the phlebotomist's role and does not replace proper exposure response. After flushing, the phlebotomist must report the incident according to facility policy, complete required documentation, and obtain occupational health follow-up. This may include source-patient evaluation, baseline testing, and post-exposure prophylaxis assessment when indicated. The correct professional sequence is decontaminate first, report immediately, document accurately, and follow the exposure-control plan. This question tests standard precautions, exposure control, OSHA-related safety obligations, and emergency response in the phlebotomy environment. Reference topics: Safety and Compliance; bloodborne pathogen exposure; mucous membrane exposure; eyewash use; incident reporting.
