Phlebotomy-Technician Exam Dumps and Practice Questions

The correct source is the Safety Data Sheet. An SDS provides chemical-specific information about hazards, exposure controls, personal protective equipment, first aid, spill response, handling, storage, and disposal. During a chemical splash, the phlebotomist must follow facility policy immediately, use the eyewash or shower if indicated, notify appropriate personnel, and consult the SDS for the exact chemical involved. Current Procedural Terminology is a medical coding system and has no role in chemical exposure response. The CDC provides infection-control guidance, but it is not the primary document for a specific chemical's hazard and first-aid requirements. OSHA establishes workplace safety regulations, including hazard communication expectations, but the SDS is the actual document used at the point of exposure for chemical-specific instructions. NHA CPT safety content includes workplace safety regulations, exposure control protocols, reporting requirements, PPE, and biohazard or chemical safety practices. OSHA also describes SDSs as documents containing chemical properties, hazards, protective measures, and safety precautions. Reference topics: Safety and Compliance; chemical exposure; SDS; OSHA hazard communication.

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.

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.

For a forensic blood alcohol level, the phlebotomist should document use of a non-alcohol-based preparation, represented here by chlorhexidine preparation rather than ethanol or isopropyl alcohol. The critical issue is legal defensibility: using an alcohol-containing skin antiseptic can create a challenge that the collection process contaminated or affected the blood alcohol evidence. Ethanol and isopropyl alcohol are both inappropriate choices for this context because they are alcohols. The direction of rubbing ethanol---up and down or circular---is irrelevant; the problem is the substance itself. Chlorhexidine is the only non-ethanol/non-isopropyl option listed and is therefore the correct answer, assuming the facility's forensic kit or protocol specifies an acceptable non-alcohol preparation. The phlebotomist must also maintain chain of custody, identify the patient/donor correctly, use the proper tube, seal the specimen, document collection time, and transfer the specimen according to legal procedure. Reference topics: Special Collections; blood alcohol collection; forensic specimens; chain of custody; documentation. NHA's CPT outline includes forensic studies and chain-of-custody collection requirements.

A surgical mask is most directly indicated for droplet precautions. Droplet precautions are used for organisms transmitted through respiratory droplets generated by coughing, sneezing, or talking. The mask helps protect the phlebotomist's nose and mouth from exposure at close range. A lead apron is used for radiation protection and has no role in droplet isolation. A sterile gown alone does not protect the respiratory mucosa and is not the primary droplet precaution. Shoe covers alone do not address droplet transmission. Depending on facility signage and procedure risk, additional PPE such as eye protection, gown, or gloves may be required, but from the options given, a surgical mask is the key droplet precaution. The phlebotomist should check isolation signs before entering, bring only necessary supplies, perform hand hygiene, wear PPE correctly, and remove PPE safely before leaving. This item tests transmission-based precaution matching: contact, droplet, airborne, and protective isolation are not interchangeable. Reference topics: Safety and Compliance; droplet precautions; PPE; isolation signage; infection control.
