NHA CPT NHA Certified Phlebotomy Technician - Set 1 - Part 2

Correct Answer: The 1-3s rule, requiring rejection

a single value beyond three standard deviations violates the rule that forces run rejection because the deviation is too large to attribute to chance. The technician must investigate and rerun controls before releasing patient results. Option b is incorrect because the rule that fires at one value beyond two standard deviations functions only as a warning rather than a rejection trigger. The current value also exceeds three standard deviations, so the stricter rejection rule applies instead. Option c is incorrect because treating the value as a warning would underplay the violation, since the data point sits beyond three standard deviations. Releasing results in this situation would expose patients to results from an out-of-control analytical run. Option d is incorrect because the rule looking at range between two consecutive controls measures values exceeding four standard deviations on opposite sides of the mean. The scenario describes a single control value, so range-based logic doe

Correct Answer: About sixty to seventy percent

published patient-safety literature attributes about sixty to seventy percent of laboratory errors to the preanalytical phase, which includes test ordering, patient identification, specimen collection, and transport. Phlebotomy is the dominant component of that phase. Option a is incorrect because ten to twenty percent describes the analytical phase contribution, where modern automation has driven errors lower. The preanalytical phase remains the dominant error source, which is why patient identification training receives so much focus today. Option b is incorrect because thirty to forty percent is closer to the postanalytical share when reporting and interpretation errors are included. It still understates the preanalytical contribution, which dwarfs the other phases in published medical-error analyses today. Option c is incorrect because ninety percent overstates any single phase contribution, since errors are distributed across all three phases. No published estimate supports a nine

Correct Answer: Certificate of Waiver

a Certificate of Waiver covers FDA-classified waived tests like urine pregnancy strips, urine dipsticks, and rapid strep antigens. The certificate must be renewed every two years and confines the clinic to that simple-complexity menu of tests. Option a is incorrect because a Certificate of Compliance applies to nonwaived testing surveyed by CMS or a state agency. A clinic running only waived tests would not need that certificate, so applying for it would impose unnecessary inspection burden and cost. Option c is incorrect because a Certificate of Accreditation supports nonwaived testing inspected by a CMS-deemed accreditor like CAP or COLA. A waived-only menu does not require that level of oversight, so the simpler waiver certificate fits the practice better. Option d is incorrect because Provider-Performed Microscopy permits a provider to perform certain microscopic procedures in addition to waived tests. The clinic plans no microscopy work, so selecting this certificate would extend

Correct Answer: Not waived under CLIA

a manual differential under microscopy requires interpretive judgment and skilled morphology recognition, which places it firmly outside the waived category. The clinic would need a higher-complexity certificate before performing manual differentials under federal CLIA rules. Option a is incorrect because waived tests are limited to procedures the FDA has deemed simple, with insignificant risk of erroneous results. Manual differential interpretation does not meet that bar, so claiming waived status would misrepresent the test's complexity classification. Option b is incorrect because Provider-Performed Microscopy covers a small list of microscopic procedures performed by a provider, such as KOH preparations and fern testing. A manual leukocyte differential is not on the PPM list, so this category does not apply here. Option d is incorrect because no patient testing is permanently exempt from CLIA when performed for diagnostic, preventive, or treatment purposes. CLIA covers all hum

Correct Answer: The 10-x rule, indicating systematic shift

ten consecutive control values on the same side of the mean violate the rule that signals a systematic shift in analyzer performance. The technologist must reject the run, investigate calibration, and verify before releasing patient results downstream. Option b is incorrect because the warning rule fires when a single value sits beyond two standard deviations, which has not happened here. The pattern in this scenario is about consistent positioning relative to the mean rather than any single excursion exceeding limits. Option c is incorrect because the rule about range between two consecutive controls captures excursions exceeding four standard deviations on opposite sides. The scenario shows clustering on one side, which is the opposite signal pattern from the random-error situation that rule detects. Option d is incorrect because releasing results would ignore a clear systematic-error signal embedded in the trend. Even without any individual outlier, ten same-side values represent me

Correct Answer: About two-thirds to three-quarters full

OSHA-compliant sharps containers display an indicator line at roughly two-thirds to three-quarters capacity. Replacement must occur at that line, since letting devices fill past it risks protruding sharps and downstream injuries. Option a is incorrect because waiting until overflowing is too late and creates a serious puncture risk for housekeeping or transport staff. Fatal needlesticks have been documented in this scenario, which is exactly why the indicator line sits below the maximum fill level. Option b is incorrect because replacing the container only when the lid jams creates a pattern of overfilling and exposes anyone who touches the unit to protruding sharps. The standard relies on the indicator line, not on a mechanical failure as a trigger. Option c is incorrect because a yearly replacement schedule ignores actual fill rates and would leave high-volume draw stations chronically overfilled. Replacement timing must respond to volume reaching the indicator line, not to a calenda

Correct Answer: Prohibited except by one-handed scoop

OSHA prohibits two-handed needle recapping under the Bloodborne Pathogens Standard, allowing only a one-handed scoop technique or a mechanical recapping device when no alternative is feasible. Modern safety devices have eliminated nearly every legitimate recapping situation. Option a is incorrect because mandating two-handed recapping would directly contradict the OSHA rule and increase percutaneous exposure incidents. The standard prohibits this technique because it routinely produces accidental sticks during the moment the cap and needle approach each other. Option c is incorrect because speed is not a defense, since rushed recapping increases injury risk rather than reducing it. The prohibition is absolute outside the narrow one-handed scoop exception, regardless of how quickly or carefully the recap might be attempted. Option d is incorrect because the OSHA rule applies to every covered employee equally, with no exemption based on professional title. Physicians have no special priv

Correct Answer: Hepatitis B vaccine offered free

the standard requires employers to offer the three-dose hepatitis B vaccine series free within ten working days of initial assignment. Employees may decline by signing a specific form but later request the vaccine free. Option b is incorrect because influenza vaccination is recommended in many healthcare settings but is not required under the Bloodborne Pathogens Standard. Many employers mandate flu vaccination through separate workplace policies, which differ from the OSHA hepatitis B offer requirement. Option c is incorrect because a tetanus booster is good general health practice but is not covered by the bloodborne pathogens rule. The standard targets pathogens transmitted through blood and OPIM, and tetanus is not within that exposure scope at all. Option d is incorrect because HPV vaccine is recommended by public-health agencies for sexually transmitted papillomavirus protection, not for occupational bloodborne exposure. The OSHA standard targets hepatitis B because of its high c

Correct Answer: Five years

the Sharps Injury Log must be retained for five years under the Bloodborne Pathogens Standard as amended by the Needlestick Safety and Prevention Act. Records identify devices and circumstances so safer alternatives can be evaluated and adopted. Option a is incorrect because a one-year retention period falls far shorter than the five-year requirement and would erase pattern data before safer-device decisions could be made. Federal recordkeeping demands a longer horizon to support trending and evaluation. Option b is incorrect because three years matches several state-specific recordkeeping intervals but falls short of the federal Sharps Injury Log requirement. Compliance with state law alone would not satisfy the OSHA standard, which sets the binding longer retention floor here. Option d is incorrect because thirty-year retention applies to certain employee medical records under separate OSHA rules, not to the Sharps Injury Log. Confusing these retention periods is a common trap, but t

Correct Answer: Annually and when tasks change

the Exposure Control Plan must be reviewed annually and whenever new tasks, procedures, or technologies affect occupational exposure. The Needlestick Safety and Prevention Act reinforced this cadence to keep safer-device evaluation current and effective. Option a is incorrect because a five-year review would let outdated procedures persist long after safer technologies became available. The federal cadence is much more frequent, since exposure conditions and device options change rapidly in modern healthcare environments at present. Option b is incorrect because a three-year cycle still leaves dangerous gaps and does not match federal requirements. The OSHA standard demands annual minimums plus event-driven updates, which together ensure the plan tracks real conditions in the workplace closely. Option c is incorrect because semiannual review is more frequent than required, but the rule sets only an annual minimum. While more reviews are not prohibited, calling six-month review the fede

Correct Answer: One bleach to nine water

the one-to-ten dilution combines one part bleach with nine parts water to produce ten parts total. The working solution must be prepared fresh daily, since chlorine concentration drops over time after preparation in any container. Option b is incorrect because equal parts bleach and water produces a one-to-two dilution, far stronger than the recommended working solution. Using that concentration unnecessarily would damage equipment and overexpose workers to chlorine fumes during normal cleaning of a small spill. Option c is incorrect because nine parts bleach to one part water nearly reverses the recipe and creates a dangerously concentrated solution. The fumes irritate respiratory passages and the corrosive action damages laboratory surfaces and finishes during normal cleaning of small spills. Option d is incorrect because one part bleach in two hundred parts water produces a solution far weaker than recommended for blood spills. The chlorine concentration falls below the level requir

Correct Answer: Don PPE, absorb, clean, disinfect, waste

the CDC sequence begins with donning PPE, absorbing the spill with paper towels or granules, cleaning organic matter with detergent, applying an EPA-registered tuberculocidal disinfectant, and discarding all waste in a biohazard bag. Option a is incorrect because disinfecting first wastes chemical contact time on residual organic matter and reduces effectiveness against bloodborne pathogens. Absorbent removal must happen before disinfectant application so the active agent can directly reach surface organisms during contact time. Option b is incorrect because wiping with paper alone removes visible blood but leaves bloodborne pathogens behind on the surface. Standard cleanup requires both organic-matter removal and a chemical kill step, since paper-only treatment cannot inactivate residual viral or bacterial particles. Option d is incorrect because plain water cannot inactivate bloodborne pathogens like hepatitis B virus or HIV. The standard demands an EPA-registered disinfectant, since

Correct Answer: EPA-registered, hospital-grade, tuberculocidal

blood spill disinfectants must be EPA-registered, hospital-grade products with a tuberculocidal claim, since that action exceeds the kill threshold needed for enveloped bloodborne viruses. A freshly prepared one-to-ten bleach dilution also satisfies the requirement. Option a is incorrect because plain dish detergent emulsifies organic matter but does not inactivate bloodborne pathogens. Detergent should be paired with disinfectant during cleanup, since detergent alone leaves the surface contaminated with infectious agents after the visible material is wiped. Option b is incorrect because seventy percent isopropyl alcohol works for skin antisepsis before venipuncture but is not the right choice for surface blood spills. Alcohol evaporates too quickly to maintain the contact time needed for full disinfection of contaminated hard surfaces. Option c is incorrect because ammonia-based glass cleaner is designed for transparency on glass and offers no proven kill claim against bloodborne path

Correct Answer: Red color or biohazard symbol

the standard accepts either a red color-coded bag or a fluorescent orange or orange-red bag with the biohazard symbol. Either marking signals regulated waste status to staff, transporters, and emergency responders during handling. Option a is incorrect because a plain white opaque bag offers no hazard communication and would not satisfy OSHA labeling rules. Regulated waste must carry a recognizable identifier so anyone handling the bag knows to apply biohazard precautions during transport and disposal. Option c is incorrect because metal staples are not part of the standard's closure or identification requirements, and they introduce sharp risk during handling. Closure must be tight and leakproof, but the OSHA rule prefers tied or heat-sealed methods over staples. Option d is incorrect because the word 'trash' written in marker tells staff nothing about the regulated nature of the contents. Regulated medical waste demands the biohazard symbol or red coding, neither of wh

Correct Answer: Documentation supports OSHA training duties

a printed procedure card supports OSHA training and worker information duties under the Bloodborne Pathogens Standard. Workers must know how to manage spills, and a kit-resident card reinforces the steps when an incident interrupts normal workflow suddenly. Option b is incorrect because bag fill is unrelated to printed instructions, since the card is informational rather than absorbent. Spill kit contents include absorbent powder for that purpose, while the card serves a separate role tied to training and procedural reinforcement. Option c is incorrect because treating the card as marketing dismisses its compliance function and ignores OSHA training expectations. Manufacturers often brand materials, but the procedural content drives regulatory value, not the logo printed at the top of the page. Option d is incorrect because the card does not carry a state license, since licensing applies to the laboratory rather than to individual cleanup tools. State licensure documents live with admi

Correct Answer: Wash the wound with soap and water

the universally taught first step after a needlestick is to wash the wound with soap and water for at least thirty seconds. Reporting follows immediately afterward so testing and prophylaxis can begin promptly. Option a is incorrect because applying a tourniquet above the wound restricts circulation unnecessarily and provides no benefit during a needlestick exposure. Tourniquets address arterial bleeding control rather than infection prevention, and using one here would create a separate distal injury risk. Option b is incorrect because squeezing or 'milking' the wound has not been shown to reduce viral transmission and may worsen tissue trauma. Current guidance discourages this practice, since it adds local injury without lowering the risk of bloodborne infection from the source. Option d is incorrect because wrapping in gauze and continuing work delays exposure reporting and the prophylaxis window for HIV. PEP is most effective when started within hours, so any postponement

Correct Answer: Fifteen minutes of flushing

the ANSI Z358.1 standard requires emergency eyewash stations to deliver tepid water at a minimum of zero point four gallons per minute for at least fifteen minutes once activated. The duration supports adequate decontamination of eye exposures. Option a is incorrect because five minutes is too short to flush most chemical or infectious-fluid exposures effectively. The fifteen-minute window matches the time needed for ocular surfaces to clear contaminants and rinse residual irritant from the eye. Option c is incorrect because ten minutes still falls below the consensus standard floor and would not deliver the irrigation duration needed for serious exposure. The relevant standard sets the fifteen-minute mark precisely to ensure complete removal of contaminants from ocular surfaces. Option d is incorrect because thirty minutes exceeds the requirement, and while longer flushing is not harmful, the rule sets fifteen as the minimum. Setting station design to thirty would not be wrong, but th

Correct Answer: Twenty gallons per minute

the standard requires a drench shower to deliver at least twenty gallons of tepid water per minute for fifteen minutes. The flow supports full body decontamination after a splash, with single-motion activation in one second. Option a is incorrect because half a gallon per minute matches the eyewash flow expectation, not the drench shower. Eyewash and shower standards share one document but use different flow rates that match the body area each fixture irrigates. Option b is incorrect because five gallons per minute is well below the shower minimum and would not deliver enough volume to decontaminate clothing and skin during a chemical splash. The standard requires four times that flow rate to ensure adequate body coverage. Option c is incorrect because ten gallons per minute remains short of the twenty-gallon requirement and would fail any inspection check against the consensus standard. Compliance demands a flow rate that fully wets the body and hair within seconds of activation.

Correct Answer: Confidential evaluation and PEP free

the standard requires the employer to offer confidential medical evaluation, baseline and follow-up testing, post-exposure prophylaxis when indicated, and a written opinion within fifteen days. All offerings must be free to the employee involved. Option b is incorrect because a hospital food voucher has no place in the post-exposure protocol, which centers on medical evaluation and prophylaxis. The standard prescribes specific clinical offerings rather than peripheral perks unrelated to viral exposure assessment and treatment in clinics. Option c is incorrect because mandatory unpaid leave is not part of the OSHA exposure response and would penalize the worker for an occupational injury. The federal standard supports clinical evaluation without imposing financial loss on the employee for needing assessment and treatment. Option d is incorrect because a parking spot is unrelated to bloodborne pathogen exposure response. The standard outlines clinical evaluation, source testing, and prop

Correct Answer: Within one to two hours

CDC guidance recommends starting HIV post-exposure prophylaxis within one to two hours of exposure, since viral integration into host cells happens quickly. The window stays reasonable up to seventy-two hours, but earlier initiation wins. Option a is incorrect because waiting up to seventy-two hours forfeits the window in which antiretroviral medications prevent viral integration most effectively. Seventy-two hours is the outer limit of benefit, but guidance emphasizes earliest possible initiation rather than delay. Option b is incorrect because waiting several days passes the seventy-two hour outer limit beyond which PEP loses meaningful effectiveness. Initiating treatment late wastes the medication regimen and exposes the worker to side effects without protective benefit. Option d is incorrect because waiting until seroconversion eliminates the entire purpose of post-exposure prophylaxis, which is to prevent infection from establishing. Once seroconversion occurs, the worker has alre
