116. Frage
A phlebotomist observes that the lid of a sharps container will not close. Which of the following actions should the phlebotomist take?
Antwort: A
Begründung:
The sharps container should be replaced. A sharps container must be closable, puncture-resistant, leak-resistant, and properly labeled or color-coded. If the lid will not close, the container no longer provides safe containment and creates a needlestick or exposure hazard. Continuing to use it is unsafe even if it has not reached the fill line. Emptying sharps into another container is strictly inappropriate because it requires handling contaminated needles and increases exposure risk. Taping the opening closed is not an approved correction and does not restore the container's designed safety function. The phlebotomist should obtain an approved replacement container and report the defective container according to facility protocol. This is not a minor housekeeping issue; sharps disposal is an engineering-control requirement designed to prevent occupational exposure to bloodborne pathogens. Phlebotomy technicians must dispose of needles immediately after use, never recap used needles, and never place sharps in regular trash or soft biohazard bags. Reference topics: Safety and Compliance; sharps disposal; engineering controls; needlestick prevention.
117. Frage
A phlebotomist is preparing to perform venipuncture on a patient who has had a right-sided mastectomy. Which of the following collection sites should the phlebotomist select?
Antwort: C
Begründung:
The phlebotomist should select the left antecubital area because the patient has had a right-sided mastectomy. Venipuncture should generally be avoided on the side of a mastectomy due to the risk of impaired lymphatic drainage, lymphedema, infection, and delayed healing. The right cephalic and right basilic veins are on the affected side and should not be used unless a provider specifically authorizes collection from that side. The left femoral artery is not an appropriate routine phlebotomy site and arterial collection is outside standard venipuncture practice unless performed under specialized authorization and scope. The left antecubital area is the safest option listed because it uses the unaffected arm and provides standard venipuncture access. The technician should still assess vein suitability, avoid sites with IVs, edema, scarring, hematoma, or infection, and follow facility policy if no acceptable site is available. This question tests contraindicated sites and safe site selection, not simply vein-name recall. Reference topics: Routine Blood Collections; mastectomy precautions; venipuncture site selection; contraindicated sites; patient safety.
118. Frage
Which of the following complications can a phlebotomist cause by underfilling a gray-topped tube?
Antwort: A
Begründung:
Underfilling a gray-topped tube can contribute to hemolysis and specimen rejection because the blood-to-additive ratio becomes incorrect. Gray-top tubes commonly contain sodium fluoride and potassium oxalate. When the tube is underfilled, the additive concentration becomes excessive relative to the blood volume, which can damage cells and interfere with specimen integrity. Hemolysis means red blood cells rupture, releasing intracellular contents into the serum or plasma and potentially altering test results. Iatrogenic anemia is caused by excessive or repeated blood removal from a patient, not by underfilling one additive tube. "Homeostasis" is the body's general maintenance of internal stability and is not a phlebotomy complication in this context; the clinically relevant term would be hemostasis. Thrombocytosis means an elevated platelet count and is not caused by underfilling a gray-top tube. The technical lesson is blunt: additive tubes must be filled to the required volume and mixed gently by inversion. Reference topics: Processing Specimens; preanalytical error; tube fill requirements; additive ratio; hemolysis.
119. Frage
Which of the following actions should a phlebotomist take to identify a patient who was admitted to a facility?
Antwort: B
Begründung:
For an admitted patient, the phlebotomist should check the patient's identification band. Inpatient identification depends on matching the patient's wristband to the requisition or collection order using required identifiers, commonly full name and date of birth or medical record number. Stating the patient's name and date of birth for the patient to confirm is weaker because it allows passive agreement and does not require the patient to actively provide identifiers. Using the medical chart alone is not sufficient because charts can be misplaced, opened to the wrong patient, or outdated. Comparing the wristband to bedside equipment is also unsafe because equipment stickers may be incorrect, moved, or not patient-specific enough to serve as the primary identifier. The correct process protects against wrong-patient collection, mislabeling, transfusion risk, diagnostic error, and specimen rejection. Reference topics: Patient Preparation; inpatient identification; wristband verification; two patient identifiers; requisition matching; specimen labeling. NHA places patient identification and preparation procedures under core CPT exam domains.
120. Frage
Which of the following conditions requires a blood transfusion due to cumulative blood loss for neonatal patients?
Antwort: A
Begründung:
Anemia is the condition that can require blood transfusion due to cumulative blood loss in neonatal patients. Neonates have a small total blood volume, so repeated laboratory collections can remove a clinically significant amount of blood over time. This is called iatrogenic blood loss and is a major concern in premature or critically ill infants who require frequent testing. If blood loss becomes excessive relative to the infant's circulating volume, hemoglobin and hematocrit can decline, producing or worsening anemia and potentially requiring transfusion. Osteochondritis involves inflammation of bone and cartilage and is unrelated to cumulative phlebotomy blood loss. Osteomyelitis is bone infection, a possible complication of improper heel puncture, but it is not the transfusion-related condition tested here. Galactosemia is a metabolic disorder screened in newborn testing, not a condition caused by repeated blood collection. The phlebotomist must use pediatric tubes, collect only the required volume, avoid unnecessary redraws, and follow minimum-volume requirements. Reference topics: Special Collections; neonatal blood collection; pediatric microcollection; iatrogenic anemia; blood volume limits.
