41. Frage
Which of the following is the minimum amount of time required to perform vigorous handwashing according to standard precaution guidelines?
Antwort: A
Begründung:
The minimum time for vigorous handwashing is 20 seconds. Proper handwashing requires wetting the hands, applying soap, rubbing all surfaces vigorously, cleaning between fingers and under nails, rinsing, and drying with a clean towel or approved drying method. Ten seconds is too short to reliably remove transient microorganisms. Two or three minutes is excessive for routine handwashing under standard precautions and is more consistent with extended surgical scrub concepts, not ordinary clinical hand hygiene before and after patient contact. In phlebotomy, hand hygiene is required before patient contact, after glove removal, after contact with blood or body fluids, after touching contaminated surfaces, and whenever hands are visibly soiled. Gloves do not replace hand hygiene; they are an additional barrier. Correct hand hygiene reduces healthcare-associated infection risk and protects both the patient and the phlebotomist. Reference topics: Safety and Compliance; standard precautions; hand hygiene; infection prevention; PPE. CDC guidance states that healthcare personnel should wash hands with soap and water for at least 20 seconds in indicated situations.
42. Frage
When performing a capillary collection, which of the following tubes should a phlebotomist collect last?
Antwort: A
Begründung:
In capillary collection, the red tube should be collected last from the options listed. Capillary order of draw differs from venipuncture order of draw because capillary blood begins clotting quickly after puncture. Tubes containing anticoagulants are collected before serum tubes to prevent platelet clumping and microclot formation that could invalidate hematology or other additive-based testing. Lavender EDTA specimens are typically prioritized early because hematology testing requires well-mixed anticoagulated whole blood. Lithium heparin is also an additive tube and should be collected before a non-additive or serum specimen. Red tubes are generally serum tubes and are collected later because clotting is expected for serum production. Microhematocrit collection depends on the procedure and whether anticoagulated capillary tubes are used, but it is not the best answer for "last" in this item. The phlebotomist must also wipe away the first drop, avoid excessive squeezing, fill microcollection containers properly, and mix additive specimens immediately by gentle inversion. NHA CPT competencies include dermal puncture, capillary order of draw, microcollection devices, and specimen integrity. Reference topics: Routine Blood Collections; capillary collection; dermal puncture; microcollection order of draw.
43. Frage
A phlebotomist notices that an outpatient appears confused and cannot state their date of birth. Which of the following actions should the phlebotomist take?
Antwort: A
Begründung:
The phlebotomist should use an approved alternate identification process. If a patient cannot reliably state their date of birth because of confusion, cognitive impairment, language barrier, or illness, the technician must follow facility policy for identification. This may involve a caregiver, legal guardian, identification band, photo identification, nurse verification, or other approved method depending on the setting. Proceeding using the requisition only is unsafe because the requisition is not the patient. Asking the patient to guess is obviously unreliable and creates wrong-patient risk. Labeling the specimen later in the laboratory is also unsafe because labeling must occur immediately after collection in the patient's presence or according to strict facility procedure. Accurate patient identification is the first major defense against specimen mislabeling, wrong diagnosis, wrong treatment, and patient harm. The phlebotomist must not improvise identity verification just to keep workflow moving. Reference topics: Patient Preparation; patient identification; alternate identification; outpatient collection; specimen labeling.
44. Frage
A patient states they ate breakfast 1 hour before a fasting lipid panel. Which of the following actions should the phlebotomist take?
Antwort: C
Begründung:
The phlebotomist should ask the provider or follow facility policy to determine whether the specimen should still be collected. A fasting lipid panel can be affected by recent food intake, especially triglyceride-related measurements and specimen lipemia. The phlebotomist must not falsely mark the specimen as fasting because that creates inaccurate documentation and can mislead clinical interpretation. Telling the patient to drink water and wait 30 minutes does not restore the required fasting state. Changing the order to another test is outside the phlebotomist's scope; only an authorized provider can change laboratory orders. The proper role is to verify patient preparation, document noncompliance if the draw proceeds, and communicate the issue through the appropriate workflow. Patient preparation is a major preanalytical control point. A technically perfect venipuncture can still produce clinically misleading results if fasting, medication timing, posture, or timing requirements are ignored. Reference topics: Patient Preparation; fasting requirements; patient compliance; requisition review; preanalytical variables.
45. Frage
Which of the following actions should a phlebotomist take when preparing a specimen for transport?
Antwort: D
Begründung:
When preparing a specimen for transport, the phlebotomist should keep the tube with the stopper upright whenever practical. Upright positioning helps reduce leakage risk, prevents specimen contact with the stopper area more than necessary, and supports safe handling during movement to the laboratory or processing area. Refrigerating infectious substances is not a universal transport rule; temperature requirements depend on the ordered test and specimen handling instructions. Agitating a tube vigorously is incorrect because it can cause hemolysis, clot disruption, foaming, or cellular damage. Additive tubes are mixed by gentle inversion according to manufacturer guidance, not shaking. Wrapping multiple tubes together is also poor practice because tubes should be protected from breakage, leakage, and cross-contamination using proper specimen transport bags, absorbent material when required, and separated compartments when applicable. Proper transport preserves analyte stability, patient safety, and biohazard control. NHA CPT processing content includes preparing specimens for testing or transport, maintaining specimen integrity based on temperature, light, or time requirements, and following handling, storage, transportation, and disposal requirements. Reference topics: Processing Specimens; specimen transport; tube handling; specimen integrity.
