質問 # 56
A phlebotomist should identify which of the following as the best site for phenylketonuria collection on an infant?
正解：C
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.

Which of the following sites should a phlebotomist use as the second choice to perform venipuncture on an adult patient?
正解：D
解説：
The cephalic vein is the second-choice vein for routine adult venipuncture. The median cubital vein is preferred first because it is usually large, well anchored, superficial, and located away from major nerves and arteries. If the median cubital vein is unavailable or unsuitable, the cephalic vein is typically selected next because it is generally accessible and safer than the basilic vein. The basilic vein is usually the last choice in the antecubital area because it lies closer to the brachial artery and median nerve, increasing the risk of serious complications if the needle placement is poor. The median antebrachial vein may be visible in the forearm but is not the standard second-choice site for routine venipuncture. Proper site selection is not cosmetic; it is risk control. The phlebotomist must evaluate vein size, depth, resilience, direction, and surrounding anatomy while avoiding sites with edema, hematoma, burns, scarring, IV lines, infection, or mastectomy restrictions. Reference topics: Routine Blood Collections; antecubital vein selection; median cubital, cephalic, and basilic veins; site safety.
質問 # 58
Which of the following actions should a phlebotomist take when a specimen requires immediate processing?
正解：B
解説：
A specimen requiring immediate processing should be delivered or processed according to stat or time-sensitive protocol. Some analytes degrade rapidly, some cells change after collection, and some tests depend on strict timing. Leaving the specimen until the next courier pickup may cause inaccurate results or rejection. Marking it routine ignores the priority and may delay care. Refrigerating it overnight is inappropriate unless specifically required, and even then it would not satisfy immediate processing. The phlebotomist must recognize priority indicators such as STAT, timed, fasting, peak/trough, chilled, protected-from-light, and immediate-spin requirements. The responsibility does not end when blood enters the tube. Specimen integrity depends on timely transport, correct temperature, proper centrifugation, and accurate documentation. If a delay occurs, the phlebotomist should communicate it according to facility policy rather than silently submitting a compromised specimen. Reference topics: Processing Specimens; stat specimens; time-sensitive processing; transport priority; specimen stability.
質問 # 59
Which of the following actions should a phlebotomist take when using a syringe for venipuncture?
正解：D
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.
質問 # 60
Which of the following is the best response when a patient asks the phlebotomist to interpret an abnormal laboratory result?
正解：C
解説：
The best response is, "Your provider can explain what the result means." Phlebotomists may explain collection procedures, specimen requirements, and general process steps, but they should not interpret laboratory results, diagnose conditions, or speculate about disease severity. Telling the patient the condition is serious is outside scope and may be inaccurate. Advising the patient to search online is unprofessional and can increase confusion or anxiety. Suggesting the laboratory made an error is also inappropriate unless an authorized investigation has identified an error. The correct response protects patient safety, scope of practice, and communication integrity. Laboratory results must be interpreted in clinical context, including history, medications, symptoms, other test results, and provider assessment. The phlebotomist should route result questions to the ordering provider or authorized clinical staff according to facility policy. This question tests professionalism and communication boundaries. Reference topics: Patient Preparation; scope of practice; patient communication; result interpretation; professional conduct.
