Which of the following values are within normal limits?

Choice A rationale

Lathering using a circular movement is an effective handwashing technique. This method ensures thorough coverage of all surfaces of the hands, including areas that are often missed, such as between the fingers and under the nails. The friction generated by the circular motions helps dislodge dirt, bacteria, and viruses from the skin. Proper lathering is a crucial step in reducing the microbial load on the hands and preventing the spread of infections.

Choice B rationale

Turning the water off using bare hands contaminates the hands after they have been washed. This action can reintroduce bacteria or viruses from the faucet handle back onto the clean hands, negating the benefits of handwashing. Proper hand hygiene protocol recommends using a paper towel or elbow to turn off the water to maintain the cleanliness achieved by washing. This step is critical in breaking the chain of infection transmission.

Choice C rationale

Washing hands for a total of 20 seconds is in line with the recommended guidelines from health organizations like the CDC. This duration is considered sufficient to effectively remove soil, dirt, and transient microorganisms from the skin. It allows enough time for the soap to act on contaminants and for mechanical action to dislodge them. Adhering to this time frame is an essential component of effective hand hygiene practices.

Choice D rationale

Holding hands below the elbows when rinsing ensures that water flows from the wrists down to the fingertips, effectively washing away soap and contaminants. This technique prevents recontamination of the hands by keeping the direction of water flow from the cleanest to the dirtiest areas. Proper rinsing is a key aspect of hand hygiene, ensuring that all soap residues, along with any remaining microorganisms, are thoroughly removed.

Choice A rationale

Donning appropriate personal protective equipment (PPE), including an N95 respirator mask, face shield, gown, gloves, and shoe coverings, is crucial to protect the nurse from potential exposure to the virus during close contact with a symptomatic client.

Choice B rationale

Teaching the client to wear a mask, hand wash, and maintain social distance is essential for preventing virus spread but is secondary to protecting the healthcare provider while collecting a test sample from a symptomatic client.

Choice C rationale

Informing the client to notify others about potential exposure is an important step in contact tracing, but it does not directly protect the nurse during the specimen collection procedure.

Choice D rationale

Notifying the charge nurse about the client's need for assignment to a COVID-19 designated area is important for appropriate care and isolation but does not directly address immediate protection for the nurse during the testing procedure.
