Which of the following areas will be the focus of the inspection during a laboratory's routine annual inspection, primarily concerning equipment maintenance logs?
Mechanical safety
Chemical safety
Radiation safety
Electrical safety
The Correct Answer is A
Choice A reason:
Mechanical safety is a critical aspect of laboratory inspections, especially when focusing on equipment maintenance logs. These logs are essential for ensuring that all mechanical equipment is functioning correctly and safely. Regular maintenance and inspection can prevent mechanical failures that could lead to workplace accidents or compromise the integrity of experiments.
Choice B reason:
Chemical safety is undoubtedly important in a laboratory setting; however, it is not the primary focus when the inspection is centered on equipment maintenance logs. Chemical safety would involve the proper storage, handling, and disposal of chemicals, which is a separate concern from the mechanical functioning of equipment.
Choice C reason:
Radiation safety is another vital area in laboratories that work with radioactive materials. However, the maintenance logs for equipment would not typically be the main focus of radiation safety inspections. Instead, radiation safety inspections would concentrate on ensuring proper shielding, monitoring, and training are in place.
Choice D reason:
Electrical safety is also essential, but similar to chemical and radiation safety, it is not the primary focus when inspecting equipment maintenance logs. Electrical safety would involve checking for proper wiring, grounding, and protection against electrical hazards.

Correct Answer is D
Explanation
Choice A Reason:
The age of the newborn is important for certain metabolic screenings, as some metabolites may not be present or at measurable levels immediately after birth. However, the requirement for the newborn to be at least 3 days old is not a standard for all blood spot collections for inborn errors of metabolism (IEM). Some screenings are performed within 24 to 48 hours after birth.
Choice B Reason:
While it is important that the circles on the filter paper are adequately filled to ensure there is enough blood for the test, the requirement for them to be at least half filled is not specified in the guidelines. The focus is usually on ensuring the blood spot is of the right size and properly saturated through the filter paper.
Choice C Reason:
The inclusion of the first drop of blood is not typically a requirement. In fact, the first drop is often wiped away to avoid contamination with tissue fluids that could affect the test results. Subsequent drops are used to fill the circles on the filter paper.
Choice D Reason:
The specimen must be completely dried before the test can be processed to prevent degradation or hemolysis of the blood sample. This is a critical step in the preparation of the sample for accurate testing of IEM. The drying process helps preserve the integrity of the metabolites to be analyzed.
Correct Answer is A
Explanation
Choice A Reason:
Anchoring a vein is a technique used to stabilize the vein during venipuncture to prevent it from rolling. The recommended practice is to anchor the vein 1 to 2 inches below the puncture site. This is done by applying gentle traction on the skin downward with the thumb, which helps to stabilize the vein and facilitate the insertion of the needle.
Choice B Reason:
Anchoring 1 to 2 inches above the puncture site is not the standard practice. This position would not provide the necessary tension on the vein to prevent it from rolling and could make the venipuncture more difficult.
Choice C Reason:
Anchoring 2 inches left of the puncture site does not provide the correct angle or tension for stabilizing the vein for a venipuncture and is not a recommended technique.
Choice D Reason:
Anchoring 1 inch right of the puncture site is also not a recommended practice. Similar to anchoring to the left, this does not provide the proper stabilization needed for a successful venipuncture.
