Which of the following precautions should be used, pending a diagnosis?Droplet and airborne precautionsContact and droplet precautionsContact and airborne precautionsStandard precautions only until a diagnosis is made

The answer to this question depends on the suspected illness. However, until a diagnosis is made, it's generally safest to use Standard Precautions. These include hand hygiene, use of personal protective equipment (PPE) like gloves and masks, safe injection practices, safe handling of potentially contaminated equipment or surfaces in the patient environment, and respiratory hygiene/cough etiquette.

1. Droplet and Airborne Precautions: These are used for diseases or germs that are spread in tiny particles in the air (like tuberculosis, measles, or chickenpox).

2. Contact and Droplet Precautions: These are used for diseases or germs that are spread by touching the patient or items in the room (like MRSA or VRE), and for diseases or germs that are spread through the air by droplets (like influenza or whooping cough).

3. Contact and Airborne Precautions: These are used for diseases or germs that are spread by touching the patient or items in the room, and through the air in tiny particles (like chickenpox, tuberculosis).

4. Standard Precautions: These are the basic level of infection control that should be used in the care of all patients all of the time. Standard Precautions include hand hygiene, use of personal protective equipment, safe injection practices, safe handling of potentially contaminated equipment or surfaces in the patient environment, and respiratory hygiene/cough etiquette.

So, until a diagnosis is made, Standard Precautions should be used. Once a diagnosis is made, the precautions can be tailored to the specific disease or germ.
