100. Frage
Which of the following types of medication is an indication for an INR draw?
Antwort: D
Begründung:
An anticoagulant is the medication type most directly associated with an INR draw. INR, or international normalized ratio, is used to evaluate clotting time and is especially important for monitoring patients who take warfarin or other anticoagulant therapy. These medications reduce the blood's ability to clot, so laboratory monitoring helps determine whether the patient is within the therapeutic range or at risk for bleeding or clotting complications. Anti-inflammatory medications may affect bleeding risk in some situations, but they are not the primary indication for an INR draw. Antihistamines are used for allergic symptoms, and antiemetics are used for nausea or vomiting; neither is routinely monitored by INR. From a phlebotomy standpoint, anticoagulant therapy also alerts the technician to apply pressure longer after venipuncture and observe for prolonged bleeding. Reference topics: Special Collections; coagulation testing; point-of-care INR; medication-related collection considerations; hemostasis. The NHA CPT test plan includes special collections, waived testing, and coagulation/hemostasis-related competencies.
101. Frage
A phlebotomist enters a patient's room and finds the patient motionless and cyanotic. Which of the following actions should the phlebotomist take?
Antwort: A
Begründung:
The first action is to assess responsiveness by speaking loudly and directly to the patient, such as asking whether they are okay. A motionless, cyanotic patient may be in respiratory or cardiac arrest, but the phlebotomist must follow the emergency response sequence rather than jumping to airway maneuvers, rescue breaths, or AED use before confirming responsiveness and activating help according to facility protocol. The head-tilt/chin-lift maneuver is an airway-opening step, but it follows initial responsiveness assessment and emergency activation. Rescue breaths are not the first step and are performed only within the appropriate CPR sequence and training level. Applying an AED is appropriate when cardiac arrest is suspected and the emergency response process has been initiated, but the first immediate action from the options is responsiveness assessment. NHA CPT safety content includes recognizing emergencies, initiating first aid, responding to codes, and CPR-related guidelines. Reference topics: Safety and Compliance; emergency recognition; CPR sequence; first aid response.
102. Frage
Which of the following laboratory departments performs a CBC and ESR?
Antwort: C
Begründung:
CBC and ESR testing are performed in the hematology department. A complete blood count evaluates formed elements of blood, including red blood cells, white blood cells, hemoglobin, hematocrit, platelet count, and sometimes differential cell counts. ESR, or erythrocyte sedimentation rate, is also a hematology procedure because it measures the rate at which red blood cells settle in anticoagulated blood over a defined time. Chemistry handles serum or plasma analytes such as glucose, electrolytes, enzymes, renal markers, liver markers, and metabolic panels. Serology focuses on immune reactions, antibodies, antigens, and infectious or immunologic testing. Microbiology deals with organisms, cultures, stains, and susceptibility testing. Knowing laboratory departments helps the phlebotomist route specimens correctly, answer workflow questions accurately, and understand tube selection and specimen handling requirements. For CBC and ESR, anticoagulated whole blood is typically required, commonly collected in lavender-top EDTA tubes depending on the laboratory's procedure. NHA CPT competencies include laboratory departments, blood components, specimen processing, specimen transport, and communication of laboratory information. Reference topics: Processing Specimens; hematology department; CBC; ESR; specimen routing.
103. Frage
Which of the following actions should the phlebotomist take after filling the last tube of a venipuncture procedure?
Antwort: D
Begründung:
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.
104. Frage
Which of the following tests should a phlebotomist anticipate to complete for a patient who has a fever of unknown origin?
Antwort: D
Begründung:
For a patient with fever of unknown origin, the phlebotomist should anticipate blood culture collection. Blood cultures are ordered to detect microorganisms in the bloodstream and are especially important when infection, bacteremia, or sepsis is suspected. Fever without a known source is a classic clinical reason for obtaining cultures before antimicrobial therapy when possible. ESR may support evaluation of inflammation, but it does not identify bloodstream infection. Immunology tests may be used for immune or infectious disease investigations, but they are not the primary phlebotomy collection expected for fever of unknown origin. Rapid plasma renin evaluates the renin-angiotensin system and is associated with blood pressure and endocrine evaluation, not unexplained fever. Blood culture collection requires strict aseptic technique, correct antiseptic contact time, proper bottle order, adequate volume, correct number of sets, documentation of collection site, and timely transport. Contamination can produce false-positive results and inappropriate treatment. NHA CPT competencies include blood culture collection, special collections, infection control, site preparation, bottle handling, and specimen integrity. Reference topics: Special Collections; blood cultures; fever workup; contamination prevention.
