Final answer:
The recommended time for proper hand hygiene as shown by the nurse is a minimum of 20 seconds. This period is essential for effectively removing pathogens and preventing the spread of diseases, as per CDC recommendations.
Step-by-step explanation:
The nurse demonstrates proper hand hygiene by pointing out that the process should take a minimum of 20 seconds. Proper handwashing is essential to prevent the spread of pathogens and is critical for public health and safety, particularly in a clinical setting. It involves five key steps that begin with wetting the hands, applying soap, and including a thorough scrubbing of the entire hand surface, wrists, between the fingers, and under the fingernails. The Centers for Disease Control and Prevention (CDC) recommends scrubbing your hands for at least 20 seconds, which can be timed by humming the "Happy Birthday" song twice from beginning to end.
Handwashing is important for everyone, especially health-care workers, to reduce the risk of transferring microbes and infectious diseases. It is recommended before and after various activities such as preparing food, using the toilet, and after sneezing or coughing. To achieve the most effective handwashing, one should use soap and warm running water, following the proper procedure.
