Which of the following should be collected first for tests including CBC, chemistry panel, lead, and a toxicology screen via capillary puncture?

Choice A reason:
Immunization schedules are not regulated by OSHA. They are typically overseen by public health agencies such as the Centers for Disease Control and Prevention (CDC) in the United States. These agencies provide guidelines on when and which vaccines should be administered to various populations.

Choice B reason:
Patient privacy is primarily regulated by the Health Insurance Portability and Accountability Act (HIPAA), not OSHA. HIPAA sets the standard for protecting sensitive patient health information from being disclosed without the patient's consent or knowledge.

Choice C reason:
The accuracy of laboratory results falls under the purview of the Clinical Laboratory Improvement Amendments (CLIA), which are federal regulatory standards that apply to all clinical laboratory testing performed on humans in the United States, except for clinical trials and basic research.

Choice D reason:
Universal precautions are indeed regulated by OSHA. These are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes. These precautions are designed to protect workers from exposure to diseases spread by blood and certain body fluids.

Choice A reason:
Collecting the specimen in an SST (serum separator tube) is not suitable for ABG (arterial blood gas) analysis. SST tubes are used for chemistry tests that require serum separation after centrifugation and are not designed for the preservation of blood gases.

Choice B reason:
Placing the specimen in ice is the correct action when transporting a specimen for ABG analysis. Cooling the specimen slows down metabolic processes, which can alter the levels of gases and pH in the blood if not promptly analyzed. This is particularly important if there is a delay expected in the analysis of the ABG specimen.

Choice C reason:
Collecting the specimen in sodium citrate is not appropriate for ABG analysis. Sodium citrate is an anticoagulant used in coagulation studies and would interfere with the measurement of blood gases and pH levels in an ABG analysis.

Choice D reason:
Inserting the specimen in a light-resistant package is not a standard requirement for ABG specimens. While protecting specimens from light is important for certain types of tests, such as those for bilirubin, it is not necessary for ABG analysis.
