When performing venipuncture or urine collection, the safety of the health care worker requires the practice of:

The practice of standard precautions is essential for ensuring the safety of health care workers during procedures such as venipuncture and urine collection. Standard precautions are a set of infection control guidelines designed to protect healthcare professionals from exposure to blood and other potentially infectious materials, regardless of the patient's diagnosis or presumed infection status.

These precautions include the use of personal protective equipment (PPE) like gloves, masks, and eye protection, as well as appropriate hand hygiene practices. By adhering to standard precautions, healthcare workers minimize the risk of transmission of infectious agents, thereby safeguarding both their health and the health of the patients they serve.

In contrast, other options like universal precautions, while historically significant, have largely been integrated into the broader framework of standard precautions. Contact and isolation precautions are specific to certain conditions or situations and are not consistently applicable across all procedures like venipuncture or urine collection, hence standard precautions are the most suitable guidelines for general practice in these scenarios.
