Important NHA Phlebotomy-Technician Exam Questions

Answer: A

Explanation:

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.

Answer: B

Explanation:

The phlebotomist is performing two-identifier verification. Correct patient identification requires using at least two approved identifiers, commonly full name and date of birth or medical record number. The patient should actively state the identifiers when able, rather than merely confirming information read aloud by the phlebotomist. This reduces the risk of wrong-patient collection and specimen mislabeling. Chain of custody is used for legal specimens such as forensic drug or alcohol testing and involves documenting specimen control from collection through testing. Therapeutic communication describes respectful, effective interaction with the patient but is not the specific safety practice being tested. Quality control calibration applies to instruments or testing systems, not patient identification. Patient identification is one of the most important steps in phlebotomy because every later step depends on it. A properly collected specimen is clinically useless and dangerous if it belongs to the wrong patient. Reference topics: Patient Preparation; patient identification; two identifiers; specimen labeling; patient safety.

Answer: C

Explanation:

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.

Answer: D

Explanation:

The phlebotomist should give the report to the requesting provider to review and notify the patient. Laboratory results are protected health information and often require clinical interpretation. A phlebotomist should not independently review, interpret, or communicate diagnostic results unless facility policy specifically authorizes a defined action. Telling the patient the results directly can create legal, privacy, and clinical risks, especially if the result is abnormal or requires medical explanation. Asking a laboratory supervisor to interpret and report the results is also inappropriate unless that person is the authorized provider or designated reporting professional. Telling the patient to pick up results may violate release-of-information procedures and still bypass provider review. The safe workflow is to route the report to the ordering provider or authorized clinical team for interpretation, documentation, and patient notification. Reference topics: Processing Specimens; communication of results; confidentiality; HIPAA; scope of practice; postanalytical handling. NHA CPT competencies include legal responsibilities, patient confidentiality, documentation, and result communication workflows.

Answer: D

Explanation:

Recent consumption of fatty substances can elevate lipid-related analytes and can also produce lipemia, a milky or turbid appearance in serum or plasma. Therefore, the correct answer is lipid. This is why fasting status is important for certain chemistry tests, especially lipid panels or triglyceride-related testing. If the patient has not followed fasting requirements, the specimen may not reflect basal-state values and can produce misleading results. Bilirubin is primarily associated with hemoglobin breakdown and liver or biliary function; it is not directly elevated simply because the patient recently ate fatty food. Albumin is a plasma protein reflecting liver synthesis, nutrition, inflammation, or fluid status, not immediate dietary fat intake. Lipase is a pancreatic enzyme used mainly in the evaluation of pancreatic disorders and is not the same as lipids. The phlebotomist's responsibility is to verify patient compliance with fasting, medication, timing, and basal-state requirements before collection and proceed according to facility policy. Reference topics: Patient Preparation; fasting requirements; medication and basal-state compliance; preanalytical variables.
