A phlebotomist should avoid using a site with burned skin during venipuncture for which of the following reasons?
Correct Answer: A
Burned skin should be avoided for venipuncture because the tissue barrier is compromised and the site carries an increased risk of infection. A venipuncture intentionally breaches the skin, so selecting tissue that is already injured, inflamed, fragile, or poorly healed increases the chance of introducing microorganisms and worsening local tissue damage. Burned areas can also have altered circulation, scarring, tenderness, edema, and impaired healing, making vein assessment and needle control less reliable. Although damaged skin elasticity can make puncture technically difficult, the best clinical reason in this item is infection risk. Inaccuracy of laboratory results is more directly associated with sites such as IV arms, edematous tissue, hematomas, or improperly handled specimens. Vein sclerosis is associated with repeated venipuncture, medication irritation, or diseased veins, not simply the use of burned skin. The NHA CPT test plan includes venipuncture site selection, contraindicated collection sites, infection control, and patient safety under routine blood collection and safety competencies. Reference topics: Routine Blood Collections; Safety and Compliance; site selection; infection prevention.
Question 27
Which of the following actions should a phlebotomist take after receiving a critical value?
Correct Answer: C
A critical value must be reported to the provider directly and promptly according to facility policy. Critical values represent results that may indicate an immediate threat to the patient's health, so delayed communication can create patient-safety risk. The phlebotomist should follow the organization's read-back, documentation, escalation, and notification procedure, especially when the result comes from point-of-care or waived testing performed by the phlebotomist. Waiting until all collections are completed is unsafe because critical values require timely clinical action. Asking a colleague to repeat the testing is not the correct first response unless the facility's procedure specifically requires confirmatory testing and the phlebotomist is authorized to perform it. Recording the value in the chart for later nurse review is also insufficient because it does not ensure immediate provider notification. Critical value handling is part of specimen processing, communication, patient safety, and point-of-care testing responsibility. NHA CPT competencies include reporting abnormal or critical results, communicating with clinical personnel, documenting results, and following testing protocols. Reference topics: Processing Specimens; Special Collections; point-of-care testing; critical value reporting.
Question 28
Which of the following does HIPAA require all health care providers to obtain before disclosing medical information?
Correct Answer: B
HIPAA requires proper written authorization before a covered entity discloses protected health information for purposes that are not otherwise permitted by the Privacy Rule. In the answer choices, "written consent" is the closest required protection because the patient's permission must be documented, specific, and traceable. A driver's license may be used to help verify identity, but it does not authorize disclosure of medical information. Verbal consent is not sufficient for many disclosures because it lacks the required written documentation and specific authorization elements. Insurance authorization relates to payment approval or coverage verification and does not automatically permit broad disclosure of medical information. For phlebotomy practice, HIPAA compliance means discussing patient information only with authorized personnel, limiting information to the minimum necessary, protecting requisitions and labels, and avoiding disclosure in public areas. HHS states that HIPAA authorizations must be written in specific terms and may permit use or disclosure of protected health information. NHA CPT safety and compliance competencies include patient rights, privacy, confidentiality, HIPAA, and legal responsibilities. Reference topics: Safety and Compliance; HIPAA; confidentiality; protected health information.
Question 29
Which of the following actions should a phlebotomist take when transporting specimens to an outside laboratory?
Correct Answer: B
The phlebotomist should use appropriate leakproof transport packaging when specimens are transported to an outside laboratory. Specimen transport must protect the patient sample, courier, laboratory personnel, and documentation from leakage, breakage, contamination, and temperature-related instability. Requisitions should be kept separate from the specimen container, usually in an outer pouch, so paperwork is not contaminated if leakage occurs. Removing labels is never acceptable because identification must remain intact from collection through testing. Freezing all specimens is incorrect because temperature requirements are test-specific; freezing some specimens can destroy cells, alter analytes, or make the sample unsuitable. Proper transport includes correct labeling, biohazard identification, absorbent material when required, secure closure, upright positioning when appropriate, and compliance with time, light, and temperature requirements. The phlebotomist must know the difference between routine transport, chilled transport, frozen transport, and protected-from-light transport. Reference topics: Processing Specimens; specimen transport; leakproof packaging; biohazard handling; specimen integrity.
Question 30
Which of the following types of consent provides a patient with information about the methods, risks, and consequences of a procedure?
Correct Answer: C
Informed consent means the patient receives enough information to understand the nature of the procedure, including the method, purpose, risks, benefits, alternatives, and possible consequences, before agreeing. Therefore, informed consent is the correct answer. Expressed consent means the patient clearly agrees, either verbally or in writing, but the term does not by itself prove that the patient received a full explanation of risks and consequences. Implied consent occurs through the patient's actions, such as extending an arm for venipuncture after identification and explanation. Verbal consent is simply the spoken form of agreement and may be expressed, but again it does not specifically define the full disclosure requirement. In phlebotomy, routine blood collection often proceeds with implied or expressed consent after proper identification and explanation, but higher-risk or special procedures may require more formal informed consent depending on policy. The NHA CPT outline includes receiving implied, informed, or expressed consent and understanding the components required for consent. Reference topics: Patient Preparation; patient rights; consent types; communication before collection.
