58. Frage
Which of the following specimens should a phlebotomist protect from light immediately after collection?
Antwort: A
Begründung:
Bilirubin specimens should be protected from light immediately after collection because bilirubin is photosensitive. Exposure to light can degrade bilirubin and produce falsely decreased results. The phlebotomist should follow facility procedure, which may include wrapping the tube in foil or using an amber transport container. Blood urea nitrogen is not classically light-sensitive; it is generally handled as a routine chemistry analyte unless special facility requirements apply. Sodium testing does not require light protection. Hemoglobin A1c reflects long-term glycemic exposure through glycated hemoglobin and is not light-sensitive in the same way bilirubin is. The broader technical principle is that specimen handling requirements are test-specific. Some specimens require chilling, some must remain warm, some require rapid transport, some must avoid light, and some require timed collection. Failure to follow these requirements creates preanalytical error even when the venipuncture itself was performed correctly. Reference topics: Special Collections; Processing Specimens; light-sensitive specimens; bilirubin handling; specimen integrity.
59. Frage
A phlebotomist uses a point-of-care instrument to perform a prothrombin time/INR test on a patient that results in a critical value. Which of the following type of medication should the phlebotomist expect to see on the patient's medication list?
Antwort: D
Begründung:
A prothrombin time/INR test evaluates the extrinsic and common coagulation pathways and is commonly used to monitor anticoagulant therapy, especially warfarin. Therefore, when a PT/INR point-of-care result is critically abnormal, the medication category most expected on the patient's list is anticoagulants. Anticoagulants interfere with clot formation and can prolong PT/INR values, creating an increased bleeding risk if outside the therapeutic range. Opioids are analgesics and do not directly monitor through PT/INR. Antidiabetics are associated with glucose monitoring, not coagulation testing. Statins are lipid-lowering medications and are usually monitored through lipid panels and liver-related considerations, not PT/INR. A critical PT/INR value must be handled according to facility policy, documented accurately, and reported through the correct clinical pathway; the phlebotomist does not interpret or treat the result independently. The NHA CPT outline covers point-of-care testing, critical values for POC and CLIA-waived testing, hemostasis, coagulation, and reporting requirements. Reference topics: Special Collections; point-of-care testing; hemostasis and coagulation; critical value reporting.
60. Frage
Which of the following actions should a phlebotomist take when administering first aid?
Antwort: C
Begründung:
The correct first-aid action is to apply direct pressure to a patient who is hemorrhaging. Direct pressure is the immediate basic intervention to control external bleeding because it compresses the injured vessel and supports clot formation. Inserting anything into the mouth of a patient who is seizing is dangerous; it can damage teeth, obstruct the airway, or injure the responder. A fainting patient should be protected from injury, placed safely, monitored, and assisted according to facility protocol; a warm compress to the neck is not the correct primary response. A patient in shock should not be offered water because altered consciousness, nausea, or urgent medical instability creates aspiration risk and delays proper emergency care. In phlebotomy, first aid is not optional "nice-to-know" material; blood collection can trigger syncope, seizures, excessive bleeding, allergic reactions, or shock-like symptoms. The technician must stop the draw when needed, protect the patient, call for help, and follow emergency procedures. Reference topics: Safety and Compliance; first aid; hemorrhage control; emergency response; patient complications.
61. Frage
A phlebotomist has just performed quality control measurements on a glucose monitor. The values exceed the acceptable limits. Which of the following actions should the phlebotomist take?
Antwort: C
Begründung:
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.
62. Frage
A patient starts convulsing during a blood collection. Which of the following actions should the phlebotomist take?
Antwort: C
Begründung:
If a patient begins convulsing during blood collection, the phlebotomist's priority is patient safety and prevention of injury. From the choices provided, allowing the patient's limbs to move freely is correct because the phlebotomist should not restrain the patient during a seizure. Restraining can cause musculoskeletal injury and does not stop the seizure. In actual procedure, the phlebotomist should immediately stop the draw when safe, remove the tourniquet and needle, activate the safety device, call for help, protect the patient from surrounding hazards, and follow emergency protocol. Continuing the collection is unsafe because seizure activity can cause needle movement, vein trauma, needlestick exposure, and specimen compromise. A cold compress is more relevant to swelling, bruising, or selected local complications, not active convulsions. Orange juice may be appropriate only for a conscious patient with suspected hypoglycemia who can swallow safely; it is unsafe during convulsions. The NHA CPT outline includes recognizing seizures and other complications during routine blood collection, discontinuing the draw if needed, emergency response, and first aid. Reference topics: Safety and Compliance; Routine Blood Collections; seizure response; emergency care during collection.
