After greeting the patient, a phlebotomy technician is preparing to perform a blood draw on a patient in an inpatient facility. Which of the following actions should the technician take next?

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:
The BUN test measures the amount of urea nitrogen in the blood, which can indicate kidney function. Fasting is not typically required for a BUN test unless it is being conducted alongside other tests that may require fasting.

Choice B reason:
An HDL test is part of a lipid profile that measures the levels of good cholesterol in the blood. Fasting before a cholesterol test, including HDL, is often recommended to ensure accuracy, although recent guidelines have changed, allowing for nonfasting cholesterol testing in certain individuals.

Choice C reason:
An ABG test measures oxygen and carbon dioxide levels in the blood and assesses the body's acid-base balance. Preparation for an ABG test does not typically require fasting, but patients may need to stop supplemental oxygen before the test to get accurate measurements.

Choice D reason:
A CBC test, or complete blood count, does not require fasting. It measures various factors of the blood, including red and white blood cells and platelets. Fasting is not necessary unless the CBC is part of a panel of tests that includes tests requiring fasting.
