NEW QUESTION # 93
Which of the following collection sites is appropriate for a dermal puncture on an infant?
Answer: D
Explanation:
The appropriate dermal puncture site on an infant is the medial or lateral plantar surface of the heel. These areas reduce the risk of puncturing bone and provide suitable capillary blood flow for neonatal testing. The posterior curvature of the heel should be avoided because the bone may be close to the surface, increasing risk of osteomyelitis or injury. The arch of the foot is not an approved puncture site and may damage nerves, tendons, or deeper structures. The tip of the index finger is inappropriate for infants because there is insufficient tissue depth and greater risk of bone injury. Correct infant dermal puncture also requires using an age-appropriate lancet depth, warming the site if needed, cleaning and drying the skin, wiping away the first drop when required, avoiding excessive squeezing, and collecting specimens in the correct order. Infant blood volume is limited, so collection volume must be minimized. Reference topics: Special Collections; infant heel puncture; dermal puncture sites; neonatal safety; osteomyelitis prevention.
NEW QUESTION # 94
A phlebotomist must recollect a blood sample after the initial sample was rejected by the laboratory. Which of the following factors might have caused the sample to be rejected?
Answer: B
Explanation:
An underfilled collection tube is a common reason for laboratory rejection because many tests require a specific blood-to-additive ratio. This is especially critical for coagulation specimens, where insufficient blood relative to anticoagulant can falsely prolong clotting results. Underfilling can also produce inadequate specimen volume for testing, repeat analysis, or instrument requirements. A hematoma at the puncture site is a patient complication and may indicate procedural difficulty, but it does not automatically require specimen rejection unless it affected specimen quality. Use of a multiple-sample needle is a standard venipuncture method and is not a rejection criterion by itself. The cephalic vein is an acceptable antecubital vein when selected appropriately, so using it does not invalidate the specimen. Processing accuracy begins at collection: correct tube, correct volume, correct mixing, correct labeling, and correct transport. The NHA CPT outline identifies preanalytical errors, minimum and maximum volume requirements, fill levels and ratios, maintaining specimen integrity, and recollection as core processing and collection competencies. Reference topics: Processing Specimens; preanalytical errors; tube fill level; specimen rejection and recollection.
NEW QUESTION # 95
Which of the following is the purpose of centrifuging a blood specimen?
Answer: A
Explanation:
The purpose of centrifuging a blood specimen is to separate specimen components. Centrifugation uses force to separate cells from serum or plasma based on density. In serum separator tubes, centrifugation separates serum from the clot after the specimen has fully clotted. In plasma separator tubes, centrifugation separates plasma from blood cells in the presence of anticoagulant. It does not disinfect the specimen; blood specimens must still be treated as potentially infectious. It does not activate tube additives; additives function through mixing by gentle inversion after collection. It also does not increase specimen volume. Improper centrifugation can damage specimens. Centrifuging too soon, too long, too fast, or at the wrong temperature can cause hemolysis, fibrin formation, poor separation, or analyte instability. The phlebotomist must follow manufacturer and facility instructions for clotting time, centrifuge speed, duration, balancing, and specimen removal. Reference topics: Processing Specimens; centrifugation; serum and plasma separation; specimen integrity; equipment operation.
NEW QUESTION # 96
A patient refuses a blood draw after the phlebotomist explains the procedure. Which of the following actions should the phlebotomist take?
Answer: B
Explanation:
The phlebotomist should notify the nurse or provider according to facility policy. A competent adult patient has the right to refuse a blood draw, even when the test is ordered. Proceeding against the patient's refusal is unethical and can constitute battery. Asking a family member to pressure the patient is inappropriate because consent must come from the patient or legally authorized representative when applicable, not from coercion. Using a smaller needle does not address refusal unless the patient specifically refused because of needle size and then gives consent after discussion. The phlebotomist should remain professional, clarify the patient's concern within scope, avoid arguing, document or report the refusal as required, and allow authorized clinical personnel to follow up. This question tests patient rights, consent, communication, and scope of practice. Phlebotomy is invasive, so consent is not optional. The technician's authority ends where patient refusal begins unless a specific emergency or legal policy applies through authorized medical personnel. Reference topics: Patient Preparation; patient refusal; consent; patient rights; communication; documentation.
NEW QUESTION # 97
A phlebotomist is collecting a blood culture set. Which of the following actions helps reduce contamination?
Answer: C
Explanation:
Allowing the antiseptic to dry before puncture helps reduce blood culture contamination. Blood cultures require strict aseptic technique because skin organisms can enter the specimen and produce false-positive results. Repalpating the site after antisepsis with an ungloved finger contaminates the prepared area and should not be done. If repalpation is absolutely necessary, facility policy may require sterile technique or repeat antisepsis. A gray-top tube is not collected before culture bottles; blood cultures are collected first in the order of draw to maintain sterility. Cleaning only the bottle cap is incomplete because both the patient's skin and bottle access surfaces must be prepared according to procedure. Blood culture quality depends on correct skin antisepsis, adequate drying time, correct bottle order, sufficient volume, separate collection sites when ordered, and accurate documentation. Contaminated cultures can lead to unnecessary antibiotics, longer hospitalization, additional testing, and patient harm. Reference topics: Special Collections; blood cultures; contamination prevention; antiseptic drying; aseptic technique.
