105. Frage
Which of the following complications is associated with a dermal puncture?
Antwort: C
Begründung:
Osteomyelitis is the correct complication associated with dermal puncture, especially when puncture depth or site selection is improper in infants. Osteomyelitis is infection of bone, and it can occur if a lancet penetrates too deeply or if a puncture is performed over an unsafe area where soft tissue is thin and bone is close to the skin. This is why infant heel punctures must be performed only on the medial or lateral plantar surface and never on the posterior curvature or central heel. Osteoarthritis is degenerative joint disease and is not caused by dermal puncture. Osteoporosis is reduced bone density and is unrelated to capillary collection technique. Osteosarcoma is a malignant bone tumor and is not a procedural complication of phlebotomy. Proper dermal puncture requires correct lancet depth, appropriate site selection, aseptic technique, and avoidance of repeated punctures in the same area. NHA CPT content includes dermal puncture procedures, capillary collection, complications, site selection, and patient risk reduction. Reference topics: Routine Blood Collections; dermal puncture; capillary collection; pediatric site safety.
106. Frage
Which of the following actions should a phlebotomist take when transporting specimens to an outside laboratory?
Antwort: B
Begründung:
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.
107. Frage
Which of the following actions demonstrates active listening by a phlebotomist?
Antwort: A
Begründung:
Restating the patient's concern for clarification demonstrates active listening. Active listening means giving attention, confirming understanding, and responding appropriately to the patient's expressed concern. For example, if a patient says, "I always pass out," the phlebotomist might respond, "You have fainted during blood draws before, so I'm going to position you safely and get assistance if needed." Interrupting the patient to save time is poor communication and may cause the technician to miss safety information. Looking away while the patient speaks can appear dismissive and reduce trust. Saying all patients feel the same way minimizes the patient's concern and is not individualized care. Active listening improves patient cooperation, consent, safety, and collection success. It also helps identify issues such as needle fear, syncope history, allergies, fasting noncompliance, language barriers, or previous complications. In phlebotomy, communication is not soft decoration; it is a safety tool. Reference topics: Patient Preparation; active listening; patient communication; anxiety reduction; patient interview.
108. Frage
A phlebotomist notices that an outpatient appears confused and cannot state their date of birth. Which of the following actions should the phlebotomist take?
Antwort: C
Begründung:
The phlebotomist should use an approved alternate identification process. If a patient cannot reliably state their date of birth because of confusion, cognitive impairment, language barrier, or illness, the technician must follow facility policy for identification. This may involve a caregiver, legal guardian, identification band, photo identification, nurse verification, or other approved method depending on the setting. Proceeding using the requisition only is unsafe because the requisition is not the patient. Asking the patient to guess is obviously unreliable and creates wrong-patient risk. Labeling the specimen later in the laboratory is also unsafe because labeling must occur immediately after collection in the patient's presence or according to strict facility procedure. Accurate patient identification is the first major defense against specimen mislabeling, wrong diagnosis, wrong treatment, and patient harm. The phlebotomist must not improvise identity verification just to keep workflow moving. Reference topics: Patient Preparation; patient identification; alternate identification; outpatient collection; specimen labeling.
109. Frage
Which of the following actions should a phlebotomist take when obtaining a throat culture?
Antwort: D
Begründung:
When obtaining a throat culture, the phlebotomist should swab the tonsillar area and the back of the throat because these are the clinically relevant sites for detecting organisms associated with pharyngitis, such as group A Streptococcus. The swab should avoid the tongue, cheeks, teeth, and lips because contact with those surfaces can contaminate the specimen with normal oral flora and reduce diagnostic value. Swabbing the buccal areas collects cheek-cell or oral flora material, not a proper throat specimen. Swabbing visible mucus in the oral cavity is unreliable because mucus may not represent the infected pharyngeal area. Leaving the swab in the sublingual area is inappropriate because the area under the tongue is not the target site for a throat culture. Correct technique includes explaining the procedure, positioning the patient, using a tongue depressor if needed, quickly swabbing the tonsillar pillars and posterior pharynx, placing the swab in the correct transport medium, and labeling the specimen accurately. Reference topics: Special Collections; non-blood specimen collection; throat culture technique; specimen integrity; patient instructions.
