NEW QUESTION # 29
Which of the following should a phlebotomist verify for quality control protocol prior to using vacuum tubes?
Answer: C
Explanation:
Before using evacuated vacuum tubes, the phlebotomist must verify the expiration date. Expired tubes can lose vacuum, produce inadequate draw volume, compromise the blood-to-additive ratio, or contain additives that no longer perform as intended. This can directly affect specimen integrity and may lead to inaccurate results or specimen rejection. Needle integrity is also important, but it applies to needle inspection rather than vacuum tube quality control. Visible additive may be observed in some tubes, but not all additives are easily visible, and visibility alone does not confirm the tube is acceptable for use. Name on label is not checked before using an unused tube because patient labeling occurs after collection according to facility policy and positive patient identification requirements. Tube quality control includes inspecting tubes for cracks, contamination, expired dates, defective stoppers, and compromised vacuum. NHA CPT routine collection content specifically includes selecting and assembling equipment, verifying equipment quality, checking expiration dates, and inspecting evacuated tubes required for laboratory testing. Reference topics: Routine Blood Collections; evacuated tube quality control; expiration dates; equipment inspection.
NEW QUESTION # 30
A patient's recent consumption of fatty substances could result in which of the following elevated analytes?
Answer: B
Explanation:
Recent consumption of fatty substances can elevate lipid-related analytes and can also produce lipemia, a milky or turbid appearance in serum or plasma. Therefore, the correct answer is lipid. This is why fasting status is important for certain chemistry tests, especially lipid panels or triglyceride-related testing. If the patient has not followed fasting requirements, the specimen may not reflect basal-state values and can produce misleading results. Bilirubin is primarily associated with hemoglobin breakdown and liver or biliary function; it is not directly elevated simply because the patient recently ate fatty food. Albumin is a plasma protein reflecting liver synthesis, nutrition, inflammation, or fluid status, not immediate dietary fat intake. Lipase is a pancreatic enzyme used mainly in the evaluation of pancreatic disorders and is not the same as lipids. The phlebotomist's responsibility is to verify patient compliance with fasting, medication, timing, and basal-state requirements before collection and proceed according to facility policy. Reference topics: Patient Preparation; fasting requirements; medication and basal-state compliance; preanalytical variables.
NEW QUESTION # 31
A phlebotomist is collecting blood from a patient with small fragile veins. Which of the following devices is most appropriate?
Answer: C
Explanation:
A winged infusion set is most appropriate for a patient with small fragile veins. Butterfly devices provide better control, flexible tubing, and a shallower insertion angle, making them useful for hand veins, pediatric patients, geriatric patients, or difficult venous access. A 16-gauge needle is too large for routine diagnostic venipuncture and would likely damage fragile veins. A blood culture bottle adapter is used for blood culture collection but does not solve the problem of fragile vein access by itself. A lancet is used for dermal puncture, not venous collection, and may not provide the volume or specimen type required for ordered venipuncture tests. When using a winged infusion set, the phlebotomist should anchor the vein carefully, insert bevel up at a low angle, stabilize the device, monitor for infiltration, and activate the safety mechanism immediately after withdrawal. Equipment selection is a clinical safety decision, not a convenience choice. Reference topics: Routine Blood Collections; winged infusion set; fragile veins; equipment selection; venipuncture technique.
NEW QUESTION # 32
Which of the following is related to diabetes mellitus?
Answer: C
Explanation:
Glycosuria is related to diabetes mellitus because it means glucose is present in the urine. In diabetes mellitus, blood glucose can rise above the renal threshold, causing glucose to spill into the urine. This finding is classically associated with hyperglycemia and impaired glucose regulation. Proteinuria means protein in the urine and is more closely associated with kidney disease, glomerular injury, hypertension, or diabetic nephropathy as a complication rather than the direct defining finding tested here. Bacteriuria means bacteria in urine and suggests urinary tract infection or contamination. Oliguria means decreased urine output and is associated with dehydration, renal dysfunction, shock, or urinary obstruction. The key relationship is that diabetes mellitus involves abnormal glucose metabolism, so glycosuria is the most direct answer. From a phlebotomy standpoint, this links to glucose testing, fasting status, point-of-care glucose monitoring, urine testing, and patient preparation. The technician does not diagnose diabetes but must understand common terms tied to ordered specimens and clinical testing. Reference topics: Phlebotomy Fundamentals; glucose metabolism; urine terminology; diabetes-related testing; point-of-care glucose.
NEW QUESTION # 33
Which of the following tube colors is commonly used for coagulation testing?
Answer: C
Explanation:
Light-blue tubes are commonly used for coagulation testing because they contain sodium citrate. Citrate binds calcium reversibly, preventing clotting while preserving the specimen for coagulation analysis such as PT, INR, and aPTT. The tube must be filled to the required level because coagulation testing depends on a precise blood-to-anticoagulant ratio. Underfilling a light-blue tube can falsely prolong clotting results and cause specimen rejection. Lavender tubes contain EDTA and are commonly used for hematology tests such as CBC. Gray tubes often contain sodium fluoride and potassium oxalate and are used for glucose or lactate testing depending on facility protocol. Red tubes are generally serum tubes without anticoagulant or with clot activator depending on manufacturer. The phlebotomist must collect light-blue tubes in the correct order of draw and inspect for proper fill. This is a high-yield NHA-style concept because it combines tube color, additive, test department, and specimen acceptability. Reference topics: Routine Blood Collections; coagulation tubes; sodium citrate; fill volume; order of draw.
