A report of laboratory results is required to have which of the following information?
Date of specimen collection
Phlebotomist's initials
Patient diagnosis
Values of previous tests
The Correct Answer is A
Choice A reason:
The date of specimen collection is crucial for a laboratory report as it provides the context for the test results. It helps in assessing the timeliness and relevance of the results, especially when monitoring conditions that can change rapidly over time.
Choice B reason:
While the phlebotomist's initials may be recorded as part of the internal process for tracking specimen collection, they are not typically included in the patient's laboratory report. The focus of the report is on the patient and the test results, rather than on the personnel who collected the sample.
Choice C reason:
Patient diagnosis is not usually included in a laboratory report because the purpose of the report is to provide test results that may inform a diagnosis. The diagnosis is made by the healthcare provider based on the test results, along with other clinical information.
Choice D reason:
Values of previous tests may be referenced in a patient's medical record but are not a required element on a laboratory report. Each report typically presents the results of the current tests only. Comparisons to previous values, if needed, are made by the healthcare provider.

Correct Answer is A
Explanation
Choice A Reason:
The evacuated tube system is designed for the collection of multiple blood specimens using interchangeable tubes. This system utilizes a double-pointed needle, one end of which goes into the patient's vein and the other into a vacuum tube. As the blood is drawn, it automatically fills the tube until the vacuum is exhausted. The phlebotomist can then easily replace the filled tube with another without removing the needle from the patient's vein, allowing for multiple samples to be taken during a single venipuncture.
Choice B Reason:
The hypodermic needle and syringe system is typically used for manual blood draws when the evacuated tube system is not suitable, such as with small or fragile veins. This system does not use interchangeable tubes; instead, the blood is drawn into a syringe and then transferred into the appropriate tubes, which can be time-consuming and increase the risk of hemolysis or contamination.
Choice C Reason:
A winged infusion set, also known as a butterfly needle, is often used for patients with difficult veins. Like the hypodermic needle and syringe system, it does not inherently allow for the use of interchangeable multi-sample tubes. Blood is collected into a syringe or a single tube attached to the butterfly needle, and changing tubes usually requires a new puncture for each sample.
Choice D Reason:
The lancet microcollection system is used for capillary blood collection, typically from a fingerstick or heelstick. It is used for small volume samples and does not accommodate interchangeable multi-sample tubes. This method is commonly used for pediatric patients or when only a small amount of blood is needed.
Correct Answer is C
Explanation
Choice A Reason:
A glucose tolerance test is used to diagnose diabetes by measuring the body's response to glucose over a period of time. It is not used to identify bacteremia, which is the presence of bacteria in the bloodstream.
Choice B Reason:
A peripheral blood smear involves examining a sample of blood under a microscope to look for abnormalities in blood cells. While it can reveal signs of infection, it does not specifically identify bacteremia.
Choice C Reason:
A blood culture is the primary test used to detect bacteremia. It involves taking a sample of blood and incubating it to see if bacteria grow, which would indicate the presence of bacteria in the bloodstream.
Choice D Reason:
Lactic acid levels in the blood are measured to assess the severity of sepsis, a condition that can result from bacteremia. Elevated lactic acid can indicate that tissues are not getting enough oxygen, but the test itself does not identify bacteremia.
