Hand washing is the single most effective infection control measure. Handwashing practices in the patient care setting began in the early 19th century. The practice evolved over the years with evidential proof of its vast importance and coupled with other hand-hygienic practices, decreased pathogens responsible for nosocomial or hospital-acquired infections (HAI).
Option A: According to the Centers for Disease Control and Prevention (CDC), hand hygiene is the single most important practice in the reduction of the transmission of infection in the healthcare setting Transient microorganisms are often acquired by healthcare workers through direct, close contact with patients or contaminated inanimate objects or environmental surfaces. Transient flora colonizes the superficial skin layers. It can be removed by routine hand washing more easily than resident flora. These organisms vary in number depending upon body location. Healthcare-associated infections are a result of these transient organisms.
Option C: Contaminated hands of healthcare providers are a primary source of pathogenic spread. Proper hand hygiene decreases the proliferation of microorganisms, thus reducing infection risk and overall healthcare costs, length of stays, and ultimately, reimbursement. According to the CDC, hand hygiene encompasses the cleansing of your hands with soap and water, antiseptic hand washes, antiseptic hand rubs such as alcohol-based hand sanitizers, foams or gels, or surgical hand antisepsis.
Option D: Indications for handwashing include when hands are visibly soiled, contaminated with blood or other bodily fluids, before eating, and after restroom use. Hands should be washed if there was potential exposure to Clostridium difficile, Norovirus, or Bacillus anthracis. Alcohol-based hand sanitizers are the recommended product for hand hygiene when hands are not visibly soiled. Apply alcohol-based products per manufacturer guidelines on dispensing of the product. Typically, 3 mL to 5 mL in the palm, rubbing vigorously, ensuring all surfaces on both hands get covered, about 20 seconds is required for all surfaces to dry completely.
