Which of the following describes proper hand washing technique to prevent infection?

The choice that highlights the correct hand washing technique emphasizes the use of soap and water, scrubbing for at least 20 seconds, followed by rinsing and drying. This method is supported by health guidelines and is essential for effectively removing dirt, bacteria, and viruses from the hands.

When scrubbing for a minimum of 20 seconds, individuals ensure that all surfaces of the hands, including between the fingers and under the nails, are adequately cleaned. This thorough approach significantly reduces the risk of transmitting infections. Additionally, rinsing with clean water helps to wash away the soap along with the pathogens, and drying the hands afterward helps prevent recontamination.

The practices outlined in the correct choice align with the recommendations of health organizations such as the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), which stress the importance of proper hand hygiene in infection prevention.
