An 80-year-old woman

The nurse is preparing to don a gown to care for a client requiring contact precautions. When should the nurse don the gown?

Before entering the client's room.

Nurses use medical asepsis in practice to reduce the number and transfer of pathogens. Which of the following are principles of this practice? Select all that apply.

Carry soiled items, including linens, equipment, and other used articles, away from the body to prevent them from touching the clothing. Do not place soiled bed linen or any other items on the floor, which is grossly contaminated; it increases contamination of both surfaces. Move equipment away from you when brushing, dusting, or scrubbing articles. Clean the least soiled areas first and then move to the more soiled ones. Use personal grooming habits that help prevent spreading microorganisms; shampoo your hair regularly. Do not shake linens. Dust and lint particles constitute a vehicle by which organisms may be transported from one area to another.

When a nurse picks up a client's contaminated tissue without gloves and fails to wash the hands sufficiently, the nurse provides for the client's organisms to be spread by which type of transmission? (page 534)

Contact

A nurse is providing care to a client diagnosed with impetigo. The nurse would institute which type of infection control?

Contact precautions; Contact precautions are used with organisms that can be transmitted by hand- or skin-to-skin contact (e.g., during client care activities or when touching the client's environmental surfaces or care items) such as with a client with impetigo (a contagious bacterial skin infection forming pustules and yellow, crusty sores) Airborne precautions are used to protect against microorganisms transmitted by small-particle droplets that can remain suspended and become widely dispersed by air currents, such as tuberculosis or measles. Droplet precautions are used for microorganisms transmitted by larger-particle droplets which disperse into air currents, such as H. influenzae or M. pneumoniae. Protective isolation is used to prevent infection for people whose body defenses are known to be compromised, such as those who are neutropenic secondary to chemotherapy.

When leaving the room of a client requiring contact precautions after helping an unlicensed personnel (UP) bathe the client, the nurse observes the unlicensed personnel taking gloves off by grasping the inside of one gloved hand with the opposite gloved hand and peeling it off. What is the proper action of the nurse?

Demonstrate proper glove removal to the unlicensed personnel: It is important for the unlicensed personnel to learn how to remove gloves correctly. The nurse should demonstrate proper glove removal to the unlicensed personnel. There is no need to report the unlicensed personnel to the unit manager. Reassigning the unlicensed personnel is not appropriate.

A nurse is taking stock of the equipment in the room of an older adult client with pneumonia who has been on parenteral nutrition for a long time. Which equipment can transmit infection to older adult clients? (page 535)

Indwelling catheter

A nurse is taking stock of the equipment in the room of an older adult client with pneumonia who has been on parenteral nutrition for a long time. Which of the following equipment can transmit infection to older adult clients?

Indwelling catheter: Infections are often transmitted to older adult clients through equipment reservoirs (e.g., indwelling urinary catheters, humidifiers, and oxygen equipment) or through incisional sites, such as those for intravenous tubing, parenteral nutrition, or tube feedings. Use of proper aseptic techniques is essential to prevent the introduction of microorganisms. Bath blankets, face shields, and specimen containers are not part of the equipment reservoir that transmits infection easily, because they are disposed of immediately after one-time use.

Risk of loneliness, social isolation, or impaired walking may not be applicable.

The nurse is preparing a sterile field for a dressing change. How would the nurse add paper- wrapped sterile items to the sterile field?

Separate the sealed flaps and drop contents onto field.; Once a sterile field is set up, only sterile items can be placed on the field. To add paper-wrapped sterile items, after performing hand hygiene, the nurse would open the items by separating the sealed flaps and dropping the contents onto the sterile field. Wearing sterile gloves to open the package would containment the gloves. Opening the package away from the field would containment the sterile field. It is not necessary to set up a separate sterile field.

A nurse has collected the blood, urine, and stool specimens of a client with meningococcal meningitis. Which of the following precautions should the nurse take when transporting the specimens?

Specimens should be placed in sealed plastic bags to prevent their becoming contaminated or causing the transmission of infective microorganisms. Paper bags are not used for this purpose and it is not customary to swab the outside of specimen containers. Standard precautions should be implemented, but this does not necessitate the use of a gown in all cases.

For which of the following clients would the use of Standard Precautions alone be appropriate?

Standard Precautions apply to blood and all body fluids, secretions, and excretions, except sweat. Transmission-Based Precautions are used in addition to Standard Precautions for clients hospitalized with suspected infection by pathogens that can be transmitted by airborne, droplet, or contact routes, such as is the case in answers A, B, and D.

An older adult client is admitted into the hospital due to pneumonia. Which transmission-based precautions should the nurse initiate?

Standard; The nurse should implement standard precautions, as these precautions are appropriate for all hospitalized patients. There is no indication that additional precautions such as airborne, droplet, or contact precautions are needed at this time.

The nurse places the client in a private room with monitored negative air pressure.; When a client is diagnosed with tuberculosis it is important for the nurse to remember that the client should be placed in a private room with monitored negative air pressure. The client should not be placed in a room with the door open. The nurse must wear the appropriate respirator when caring for the client, but visitors must wear masks. Simply being 3 feet away will not keep the visitor from being exposed to the client. The nurse would use airborne precautions, not droplet precautions when caring for a client diagnosed with tuberculosis.

The nurse is setting up a sterile field to perform a catheterization when the patient touches the end of the sterile field. What would be the nurse's next appropriate action?

The nurse's next appropriate action would be to discard the sterile field and the supplies and start over. The client touching the end of the sterile field contaminated the field and the items on the field. The nurse cannot reuse the sterile equipment because the items are no longer sterile. The nurse cannot proceed with the procedure since the items have been contaminated. Calling for help and asking for new supplies is not the best answer. The field has been contaminated also.

The use of alcohol-based hand rubs for hand hygiene in healthcare facilities is approved by the Centers for Disease Control (CDC), but The Joint Commission (TJC) discourages its use.

This is false

A nurse is providing care to a client who has Salmonella food poisoning. The nurse understands that this pathogen was transmitted by which mechanism?

Vehicle; Vehicle transmission involves the transfer of microorganisms by way of vehicles or contaminated items that transmit pathogens; for example, food can carry Salmonella. Direct contact transmission involves body surface-to-body surface contact causing the physical transfer of organisms between an infected or colonized person and an infected host. Droplet transmission occurs when mucous membranes of the nose, mouth, or conjunctiva are exposed to secretions of an infected person who is coughing, sneezing, or talking. Airborne transmission occurs when fine particles are suspended in the air for a long time or when dust particles contain pathogens.
