Description

ATI – Infection Control Pretest Q: A nurse is about to irrigate a client’s open wound. Besides gloves, which of the following personal protective equipment should the nurse wear? A: A face shield A face shield protects the face, mouth, nose, and eyes from any potential splashes of blood or other body fluids. Irrigating a wound has the potential for splashing irrigating fluid containing blood, body fluids, and tissue particles onto the nurse's face.

Q: A nurse is washing their hands with soap and water prior to repositioning a client in bed. During the handwashing procedure, it is important to take which of the following actions? A: Wash for at least 20 seconds. Handwashing with nonantimicrobial soap and water for at least 20 seconds reduces bacterial counts and can remove loosely adherent transient flora. The Centers for Disease Control and Prevention recommends rubbing hands together vigorously for at least 20 seconds, covering all surfaces of the hands and fingers.

Q: A nurse is caring for a client who has a health care-associated infection (HAI). Which of the following describes an exogenous HAI? A: A Salmonella infection that occurs after eating contaminated food from the cafeteria An exogenous HAI is an infection acquired from pathogens found outside of the client's body, such as in contaminated food.

Q: Which of the following products can affect the permeability of latex gloves? A: Petroleum-based hand lotion The use of petroleum-based hand lotions or creams can impair the integrity of latex gloves, weakening them and increasing their permeability.

Q: Which of the following is an advantage of using alcohol-based gel? A: It takes less time to use than washing with soap and water. During an 8-hr shift, an estimated 1 hr of an intensive care unit nurse's time is saved by preforming hand hygiene with an alcohol-based gel.

Q: What should the nurse do to maintain standard precautions? A: Disinfect hands immediately after removing gloves. It is an essential component of standard precautions to disinfect hands immediately after glove removal, which often occurs at the end of a client-care procedure, and hand hygiene is mandated between client contacts. Hand hygiene is required in case the integrity of each glove has been breached, powder or other residue remains on the nurse's hands, or the nurse's hands have been contaminated during glove removal.

Q: To decontaminate their hands with an alcohol-based gel, the nurse should rub their hands together until all of the gel has evaporated and their hands are dry. Which of the following is the correct rationale for why hands should be rubbed together until dry?

A: Drying provides the full antiseptic effect. A dry environment offers better protection against the proliferation of pathogens than a moist environment does. The bactericidal alcohol components of these gels further enhance their superior antiseptic effect.

Q: After assisting a newly admitted client with removing their shoes and outerwear, the nurse notices what appears to be soil or grime on their hands. Which of the following actions should the nurse take? A: Wash their hands with soap and water. The Centers for Disease Control and Prevention recommends washing with soap and water whenever hands are visibly dirty. In this case, it is the combination of friction, running water, and the properties of soap that remove the soil from the hands.

Q: Contact precautions should be implemented for an adult client who has been hospitalized and has which of the following? A: Infectious diarrhea Contact precautions are essential for preventing the spread of certain enteric infections. These precautions mean no direct touching of the client, the environment, the equipment, or the supplies used. The client should also be placed in a private room.

Q: After completing a procedure that required donning personal protective equipment (PPE) consisting of a gown, an N95 respirator, a face shield, and gloves, which of the following should the nurse remove first when removing PPE separately? A: The gloves Gloves are considered the most contaminated and should be removed first, followed by face/eye protection, gown, and mask/respirator.

Q: A nurse is caring for a client who has Mycoplasma pneumoniae. The client has been placed on droplet precautions. Which of the following actions should the nurse take when caring for the client? A: Protect their eyes. Droplet transmission involves contact of infectious, large-particle droplets with the conjunctivae or the mucous membranes of the nose or mouth of a susceptible person. Droplets are generated by the client during coughing, sneezing, or talking and during procedures such as suctioning and bronchoscopy....
