A nurse is reinforcing teaching with the parent of a newborn about security procedures. Which of the following instructions should the nurse include?

The correct answer is Choice C.

Choice A rationale:

• While maintaining a distance of 3 feet can reduce the risk of direct contact transmission, it is not the most effective measure for contact isolation precautions.
• Contact isolation aims to prevent the spread of pathogens that can be transmitted through direct or indirect contact with the infected person or contaminated objects.
• A distance of 3 feet may not be sufficient to prevent transmission via droplets or fomites (inanimate objects that can harbor infectious agents).

Choice B rationale:

• Sterile gloves are not routinely required for contact isolation precautions.
• They are primarily used for sterile procedures or when there is a risk of exposure to blood or body fluids.
• For contact isolation, standard clean gloves are usually sufficient to protect against transmission via direct contact.

Choice C rationale:

• Leaving equipment that is used routinely in the client's room is a crucial part of contact isolation precautions.
• This practice prevents the spread of infection by minimizing the movement of potentially contaminated items outside of the isolation room.
• Equipment like stethoscopes, blood pressure cuffs, and thermometers should be dedicated to the client's use and not shared with other patients.

Choice D rationale:

• Negative-pressure airflow rooms are used for airborne isolation precautions, which are designed to prevent the spread of pathogens that can be transmitted through the air.
• Contact isolation does not specifically require a negative-pressure room, as the primary mode of transmission is through direct or indirect contact, not airborne particles.

c. Hallucination

In the scenario described, the client's experience of receiving special audible messages from the Central Intelligence Agency that no one else can hear indicates a hallucination. Hallucinations are perceptual disturbances in which a person experiences sensory perceptions without any external stimuli. They can occur in any sensory modality, such as hearing (auditory hallucinations), seeing (visual hallucinations), smelling (olfactory hallucinations), tasting (gustatory hallucinations), or feeling (tactile hallucinations).

In this case, the client is experiencing auditory hallucinations, as he is perceiving auditory stimuli (audible messages) that are not present in the external environment. Auditory hallucinations are most commonly associated with schizophrenia, although they can occur in other psychiatric disorders as well.

Derealization (option a) refers to a subjective feeling of unreality or detachment from the environment. It involves a perception that the external world is strange, distorted, or unreal. This is not the primary alteration in perception described in the scenario.

Illusion (option b) is a misinterpretation or misperception of a real sensory stimulus. It occurs when a person's perception of an actual stimulus is distorted or misunderstood. There is no indication of a misperception of a real stimulus in the scenario.

Depersonalization (option d) is a subjective experience of being detached from one's own body, thoughts, or emotions. It involves a feeling of being outside of oneself or observing oneself from a distance. This is not the primary alteration in perception described in the scenario.

Therefore, the correct answer is c. Hallucination, as the client's experience of receiving special audible messages that no one else can hear represents an auditory hallucination.
