Correct Answer: gloves.
when discussing the correct order for donning personal protective equipment (ppe), it is essential to understand that gloves are generally put on last. this sequence is crucial to maintaining the sterility and effectiveness of the gloves, which are a critical barrier against the transmission of infectious agents.
the primary reason gloves are worn last is to minimize the risk of contamination. throughout the process of putting on other pieces of ppe, such as gowns, masks, or eye protection, the hands might touch various non-sterile surfaces. if gloves were donned first, there would be a higher probability of transferring pathogens from these surfaces onto the gloves. this transfer could defeat the purpose of wearing ppe, as contaminated gloves could then come into contact with sterile areas or instruments, or directly with a patient.
moreover, the order of donning ppe is designed to overlap correctly. for instance, the gown should be put on first to cover the torso and arms, followed by a mask or respirator to secure the mouth and nose. eyewear or face shields are added next to protect the mucous membranes of the eyes. finally, gloves are worn to cover the wrists and hands, ensuring that the edge of the glove overlaps the cuff of the gown. this overlapping provides a continuous barrier of protection, reducing the risk of exposure to harmful substances or infectious materials.
in healthcare settings, like those involving dental health care personnel (dhcp), strict adherence to ppe protocols is vital. these protocols are established based on guidelines from health authorities such as the centers for disease control and prevention (cdc). the rationale is to not only protect the health workers but also to prevent the cross-contamination that could occur between patients and healthcare professionals.
in conclusion, the sequence of donning ppe is a meticulously designed procedure aimed at maximizing protection against infections. gloves are put on last to ensure they remain as sterile as possible until the point of patient contact. this practice is a fundamental aspect of infection control protocols in various health care and laboratory settings.
