Which of the following is the general concept behind standard precautions?
Ensure that employees receive training regarding workplace hazards.
Provide information about hazardous chemicals to the environment within.
Assume that all body fluids are infected with bloodborne pathogens.
Maintain a workplace that is free of environmental hazards.
The Correct Answer is C
Choice A reason:
While ensuring that employees receive training regarding workplace hazards is important, it is not the general concept behind standard precautions. Training is a part of the broader safety measures but does not encompass the core idea of standard precautions, which is to prevent infection transmission.
Choice B reason:
Providing information about hazardous chemicals within the environment is related to the Right-to-Know standard, which is part of the Hazard Communication Standard. This is not the main concept of standard precautions, which focus on preventing the spread of infections, particularly in healthcare settings.
Choice C reason:
Assuming that all body fluids are potentially infected with bloodborne pathogens is the essence of standard precautions. This approach dictates that healthcare workers should treat all body fluids as if they are infectious and therefore use appropriate protective measures to prevent exposure and transmission of diseases.
Choice D reason:
Maintaining a workplace free of environmental hazards is a broad occupational safety goal but does not specifically describe the general concept behind standard precautions. Standard precautions are more focused on infection control practices rather than the broader scope of all environmental hazards.

Correct Answer is B
Explanation
Choice A Reason:
Prepping the site with povidone iodine is not typically associated with hemoconcentration. Povidone iodine is used as an antiseptic to clean the skin before venipuncture to prevent infection. While it's important to allow it to dry to avoid sample contamination, it does not cause hemoconcentration.
Choice B Reason:
Leaving the tourniquet in place for more than 2 minutes can lead to hemoconcentration. A tourniquet is applied to engorge the veins, making them easier to puncture. However, prolonged application can result in fluid being forced out of the vein into the tissue, increasing the concentration of cells and larger molecules in the blood. This can affect certain laboratory test results by artificially increasing the levels of cellular components.
Choice C Reason:
Not refrigerating the specimen within 30 minutes does not cause hemoconcentration. However, it can affect the stability of certain analytes in the blood sample. Refrigeration is necessary for preserving the integrity of certain components of the blood until analysis, but it is unrelated to the concentration of cells within the sample at the time of collection.
Choice D Reason:
Removing the needle before the tourniquet is released does not cause hemoconcentration. This action might lead to other complications, such as hematoma formation, but it does not affect the concentration of cellular elements in the collected sample.
Correct Answer is B
Explanation
Choice A reason:
The date of birth is a common identifier, but it is not unique to an individual, as multiple patients may share the same birth date. While it is useful in conjunction with other identifiers, on its own, it does not provide a definitive identification.
Choice B reason:
The record number, often referred to as the medical record number, is a unique identifier assigned to each patient within a healthcare system. It is used to track patient information across different visits and services, making it the most reliable standalone identifier if the patient's name is not available.
Choice C reason:
An address can change over time and may not be unique, especially in large apartment buildings or for patients who are homeless or transient. It is also not specific enough to reliably identify a patient, as multiple individuals can reside at the same address.
Choice D reason:
The social security number is a unique identifier, but due to privacy concerns and the risk of identity theft, it is not the preferred method for patient identification in healthcare settings. Additionally, not all patients may have a social security number, such as non-residents or newborns.
