The nurse is applying personal protective equipment (PPE) prior to entering a client’s room. What is the correct sequence for donning (putting on) PPE?

Choice A reason: The reservoir or host refers to the environment or organism where the pathogen normally lives and multiplies. In HIV, the reservoir is the human body, but in this scenario the focus is not on where the virus resides—it is on how it was transmitted.

Choice B reason: The portal of exit is the path by which the pathogen leaves the reservoir, such as blood, respiratory secretions, or other bodily fluids. While HIV exits through blood, the question emphasizes the act of sharing needles, which is not the exit but the transmission route.

Choice C reason: The mode of transmission is the method by which the pathogen spreads from one host to another. Sharing contaminated needles is a direct mode of transmission for HIV because blood containing the virus is introduced into another person’s bloodstream. This is the critical link illustrated in the scenario.

Choice D reason: The portal of entry is how the pathogen enters the new host, such as through mucous membranes, skin breaks, or direct injection. While HIV enters through the bloodstream, the scenario highlights the act of sharing needles, which is the transmission mechanism rather than the entry point itself.

Choice A reason: Allowing a client’s dog to visit demonstrates cultural competence because it respects the patient’s emotional and spiritual needs. Pets are often considered part of family and can provide comfort, reduce stress, and improve well-being.

Choice B reason: Researching foods that a lacto-ovo vegetarian will eat shows cultural competence by respecting dietary preferences and ensuring nutritional needs are met. This demonstrates sensitivity to cultural and personal values.

Choice C reason: Including cultural foods in the patient’s tray, while ensuring they fit within medical dietary restrictions, balances cultural respect with clinical safety. This is a culturally competent action because it integrates patient preferences into care without compromising health.

Choice D reason: Telling a patient that their prayer time must wait until after a scheduled bath disregards cultural and spiritual needs. This demonstrates a lack of cultural competence because it prioritizes routine tasks over the patient’s beliefs and practices. Nurses should adapt care schedules to respect prayer times whenever possible.
