Which of the following actions should a phlebotomist take when obtaining a throat culture?
正解：C
解説：
When obtaining a throat culture, the phlebotomist should swab the tonsillar area and the back of the throat because these are the clinically relevant sites for detecting organisms associated with pharyngitis, such as group A Streptococcus. The swab should avoid the tongue, cheeks, teeth, and lips because contact with those surfaces can contaminate the specimen with normal oral flora and reduce diagnostic value. Swabbing the buccal areas collects cheek-cell or oral flora material, not a proper throat specimen. Swabbing visible mucus in the oral cavity is unreliable because mucus may not represent the infected pharyngeal area. Leaving the swab in the sublingual area is inappropriate because the area under the tongue is not the target site for a throat culture. Correct technique includes explaining the procedure, positioning the patient, using a tongue depressor if needed, quickly swabbing the tonsillar pillars and posterior pharynx, placing the swab in the correct transport medium, and labeling the specimen accurately. Reference topics: Special Collections; non-blood specimen collection; throat culture technique; specimen integrity; patient instructions.

Which of the following actions should a phlebotomist take when using a syringe for venipuncture?
正解：B
解説：
When using a syringe for venipuncture, the phlebotomist should transfer blood into tubes using a safety transfer device. A syringe may be used for fragile veins or situations where vacuum pressure could collapse the vein, but it introduces additional handling risk. Pulling the plunger forcefully can cause vein collapse, pain, and hemolysis. Removing tube stoppers and pouring blood into tubes is unsafe because it exposes the specimen and staff to blood, increases contamination risk, and disrupts additive ratios. Attaching a used needle to fill evacuated tubes is dangerous and creates needlestick risk. A safety transfer device allows blood to move from the syringe into evacuated tubes while maintaining a closed system and preserving order of draw. The phlebotomist should also avoid excessive force, fill tubes correctly, mix additive tubes gently, activate safety features, and discard sharps immediately. Reference topics: Routine Blood Collections; syringe method; blood transfer device; hemolysis prevention; sharps safety.

A phlebotomist should identify which of the following as the best site for phenylketonuria collection on an infant?
正解：D
解説：
The best site for phenylketonuria, or PKU, collection on an infant is the medial or lateral plantar surface of the heel. PKU screening is a newborn metabolic screening test commonly collected by heel stick onto filter paper. The medial and lateral heel areas are selected because they provide adequate capillary blood flow while reducing the risk of puncturing bone. The central area of the heel is unsafe because the calcaneus may be closer to the puncture site, increasing the risk of bone injury or osteomyelitis. Fingertip puncture is inappropriate for infants because the tissue is small, bone is close to the surface, and the site does not provide the recommended specimen collection area for newborn screening. Proper PKU collection also requires warming the heel when indicated, allowing blood to flow freely, filling filter-paper circles completely from one side, avoiding layering, and allowing the specimen to dry properly before transport. NHA CPT special collection content includes collecting blood for metabolic syndromes such as PKU, filter-paper collection techniques, pediatric considerations, and minimum/maximum volume requirements. Reference topics: Special Collections; PKU collection; infant heel puncture; filter-paper specimen collection.
質問 # 52
A phlebotomist is collecting a blood culture set. Which of the following actions helps reduce contamination?
正解：B
解説：
Allowing the antiseptic to dry before puncture helps reduce blood culture contamination. Blood cultures require strict aseptic technique because skin organisms can enter the specimen and produce false-positive results. Repalpating the site after antisepsis with an ungloved finger contaminates the prepared area and should not be done. If repalpation is absolutely necessary, facility policy may require sterile technique or repeat antisepsis. A gray-top tube is not collected before culture bottles; blood cultures are collected first in the order of draw to maintain sterility. Cleaning only the bottle cap is incomplete because both the patient's skin and bottle access surfaces must be prepared according to procedure. Blood culture quality depends on correct skin antisepsis, adequate drying time, correct bottle order, sufficient volume, separate collection sites when ordered, and accurate documentation. Contaminated cultures can lead to unnecessary antibiotics, longer hospitalization, additional testing, and patient harm. Reference topics: Special Collections; blood cultures; contamination prevention; antiseptic drying; aseptic technique.
質問 # 53
A phlebotomist centrifuges a serum specimen before it has fully clotted. Which of the following is most likely to occur?
正解：D
解説：
If a serum specimen is centrifuged before it has fully clotted, fibrin strands can form in the serum. These strands can interfere with testing instruments, cause sample aspiration problems, and lead to inaccurate results or specimen rejection. Serum specimens must be allowed to clot for the required time before centrifugation. Centrifugation does not increase specimen volume, neutralize additives, or sterilize blood. Blood specimens remain potentially infectious regardless of processing. This question tests the difference between serum and plasma. Serum is the liquid portion after clotting; plasma is the liquid portion of anticoagulated blood. If the phlebotomist rushes serum processing, the specimen may look separated but still contain fibrin. The correct workflow includes observing required clot time, balancing centrifuge tubes, using the correct speed and duration, and removing specimens promptly after centrifugation when required. Speed is not quality; specimen integrity is quality. Reference topics: Processing Specimens; clotting time; serum processing; centrifugation; fibrin formation.
