For blood culture collection, the phlebotomist should document the site of collection. Blood cultures are often drawn from separate sites to help distinguish true bloodstream infection from contamination. Accurate site documentation supports interpretation if one bottle set grows organisms and another does not. It also provides traceability for collection quality, timing, and possible contamination review. Type of culture media is generally determined by the blood culture bottle system and laboratory protocol; it is not the key patient-specific documentation item in this question. Blood collection technique is expected to follow facility policy, but it is not typically the primary required field compared with date, time, collector identity, and site. Informed consent is not usually a separate required document for routine blood culture collection unless facility policy or special circumstances require it. Blood culture technique requires strict antisepsis, appropriate bottle preparation, correct order, sufficient volume, and avoidance of contamination. NHA CPT special collection content includes performing blood culture collections, blood culture locations, skin preparation, equipment, volume requirements, bottle preparation, and order of draw. Reference topics: Special Collections; blood culture collection; site documentation; contamination control.

When glucose monitor quality control values exceed acceptable limits, the phlebotomist should perform the manufacturer's recommended actions. Out-of-range QC means the instrument, strips, controls, operator technique, storage conditions, or environmental factors may be unreliable. Patient testing should not proceed until the problem is corrected and QC results return to acceptable range according to the device instructions and facility procedure. Cleaning the monitor may be part of troubleshooting, but it is not automatically the complete or correct response unless the manufacturer's protocol identifies contamination as the cause. Replacing batteries may be appropriate only if the device indicates low power or the manufacturer's instructions direct it. Documenting the values is necessary, but documentation alone does not correct the failed QC or validate patient results. The correct professional action is to follow the device-specific troubleshooting and QC procedure, repeat controls when indicated, remove defective materials from use, and notify the appropriate supervisor if unresolved. NHA CPT competencies include point-of-care testing, quality control, CLIA-waived testing, equipment maintenance, and accurate documentation. Reference topics: Special Collections; point-of-care glucose testing; quality control; manufacturer instructions.

To prevent reflux, the patient's arm should be kept in a downward position so the collection tube remains below the puncture site. Reflux occurs when blood or tube additive flows backward from the tube into the patient's vein. Keeping the tube below the venipuncture site and allowing tubes to fill properly reduces this risk. Holding the tube above the puncture site increases the chance of backflow. Removing the tube before it fills can create incorrect blood-to-additive ratios and does not prevent reflux. Inserting the needle bevel down is incorrect technique; venipuncture needles are inserted bevel up to enter the vein smoothly and reduce trauma. Reflux prevention also includes using proper tube position, avoiding excessive movement, not pushing tube contents toward the patient, and releasing the tourniquet appropriately. This is especially important with additive tubes because additive contamination of the patient's circulation, while uncommon, is a preventable safety concern. Reference topics: Routine Blood Collections; reflux prevention; evacuated tube technique; arm positioning; tube handling.

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.

The appropriate dermal puncture site on an infant is the medial or lateral plantar surface of the heel. These areas reduce the risk of puncturing bone and provide suitable capillary blood flow for neonatal testing. The posterior curvature of the heel should be avoided because the bone may be close to the surface, increasing risk of osteomyelitis or injury. The arch of the foot is not an approved puncture site and may damage nerves, tendons, or deeper structures. The tip of the index finger is inappropriate for infants because there is insufficient tissue depth and greater risk of bone injury. Correct infant dermal puncture also requires using an age-appropriate lancet depth, warming the site if needed, cleaning and drying the skin, wiping away the first drop when required, avoiding excessive squeezing, and collecting specimens in the correct order. Infant blood volume is limited, so collection volume must be minimized. Reference topics: Special Collections; infant heel puncture; dermal puncture sites; neonatal safety; osteomyelitis prevention.
