質問 # 14
A phlebotomist is scheduled to perform a venipuncture on a patient who had a bilateral radical mastectomy. Which of the following actions should the phlebotomist take?
正解：A
解説：
The phlebotomist should contact the provider for approval. After a mastectomy, especially radical mastectomy with lymph node involvement, venipuncture on the affected side is generally avoided because impaired lymphatic drainage can increase risk for lymphedema, infection, delayed healing, and patient complications. With a bilateral radical mastectomy, both arms may be restricted, so the phlebotomist should not independently choose an alternate arm vein. Drawing from an ulnar vein is not a standard solution and could still be in a restricted extremity. Requesting surgical outpatient records is not the immediate collection action and does not provide authorization to proceed. Obtaining a specimen from the subclavian vein is outside the phlebotomist's routine scope and would be a provider-level invasive procedure. The correct approach is to pause, follow facility policy, notify the nurse or provider, and obtain explicit direction for an approved site or alternate collection method. Reference topics: Routine Blood Collections; site contraindications; mastectomy precautions; provider communication; patient safety.
質問 # 15
Which of the following methods should a phlebotomist use to anchor a vein?
正解：D
解説：
The vein is anchored by placing the thumb of the free hand below the intended puncture site and gently pulling the skin taut. This stabilizes the vein, reduces rolling, creates a firmer puncture surface, and supports accurate needle entry. Anchoring above the site is unsafe because it places the phlebotomist's hand in the direction of needle travel and increases needlestick risk. Using two fingers instead of the thumb provides less controlled traction and may interfere with the venipuncture angle or contaminate the prepared site. The phlebotomist should avoid touching the cleansed puncture site after antisepsis unless the site is re-cleansed. Proper anchoring is especially important for superficial or mobile veins because failure to stabilize the vein can cause missed access, hematoma formation, probing, patient discomfort, or specimen collection failure. The NHA CPT outline identifies anchoring the vein below the venipuncture site and knowledge of anchoring techniques as routine venipuncture competencies. Reference topics: Routine Blood Collections; site selection; anchoring below venipuncture site; venous anatomy and safe insertion technique.
質問 # 16
Which of the following conditions is a reason for specimen rejection?
正解：D
解説：
A clotted lavender-top specimen is a reason for specimen rejection. Lavender-top tubes contain EDTA anticoagulant and are used for tests such as CBCs, which require anticoagulated whole blood. If the specimen clots, the cellular components are trapped in the clot, platelet counts can be falsely low, and automated hematology analysis becomes unreliable. Properly labeled specimens, correctly filled light-blue tubes, and specimens transported upright are acceptable practices, not rejection causes. A clotted lavender specimen usually results from failure to mix the tube properly immediately after collection, delayed inversion, underfilling or collection difficulty, or drawing blood slowly and allowing clotting to begin before the specimen contacts the additive. The correct prevention is to fill the tube to the required volume and gently invert it the recommended number of times immediately after collection. The phlebotomist should never shake the tube, because vigorous agitation can cause hemolysis. Reference topics: Processing Specimens; specimen rejection; EDTA tube mixing; clotted specimens; hematology testing.
質問 # 17
Which of the following actions should the phlebotomist take after filling the last tube of a venipuncture procedure?
正解：D
解説：
After the last tube has filled, the phlebotomist must complete the venipuncture termination sequence safely. The correct action from the choices is to withdraw the needle from the puncture site. In routine venipuncture, the tourniquet is released before needle removal, then the needle is withdrawn smoothly, the safety device is activated, and pressure is applied with clean gauze or cotton only after the needle is out. Applying cotton while the needle is still inserted can cause the needle to cut or traumatize the vein. Cleaning the site with antiseptic occurs before puncture, not after collection. A warm compress is not part of routine completion; it may be used only for selected complications or difficult venous access before collection. The NHA CPT outline specifically includes standard tourniquet removal, needle removal, safety-device use, post-procedural care, and bandaging as routine blood collection competencies. Reference topics: Routine Blood Collections; removing tourniquet, tubes, and needle; post-procedural patient care.
質問 # 18
A phlebotomist is performing a glucose tolerance test. Which of the following actions should the phlebotomist take after the patient drinks the glucose solution?
正解：A
解説：
After the patient drinks the glucose solution, the phlebotomist should start timing according to the test protocol. Glucose tolerance testing depends on strict timed specimen collection after ingestion of a measured glucose load. If timing is inaccurate, the results may be invalid or misleading. The patient should not eat crackers because additional food intake can alter glucose results. Exercise should also be avoided unless specifically directed because physical activity can affect glucose metabolism. Collecting all remaining specimens immediately defeats the purpose of the timed test, which evaluates the body's glucose response over defined intervals. The phlebotomist must verify fasting status, collect the baseline specimen if required, ensure the patient consumes the glucose solution within the allowed time, document the time finished, and collect subsequent specimens at exact ordered intervals. If the patient vomits, eats, leaves, or misses a timed draw, the phlebotomist should follow facility policy and notify appropriate personnel. Reference topics: Special Collections; glucose tolerance testing; timed specimens; patient preparation; test protocol compliance.
