What is the priority intervention for the nurse to enhance meeting the psychosocial needs of a client on transmissionbased precautions?

Choice A reason: The client is in a private room is not an observation that requires further action by the nurse, because it is appropriate and desirable. The client with reduced immunity should be in a private room, as it can reduce the exposure to pathogens or allergens that may cause infection or inflammation. The client with reduced immunity has a weakened or impaired immune system, which makes them more susceptible and vulnerable to infection. The private room can also provide privacy, comfort, and security for the client.

Choice B reason: The client has a dedicated vital signs machine is not an observation that requires further action by the nurse, because it is appropriate and desirable. The client with reduced immunity should have a dedicated vital signs machine, as it can prevent the crosscontamination or transmission of pathogens or allergens that may cause infection or inflammation. The vital signs machine is a device that measures the blood pressure, pulse, temperature, and oxygen saturation of the client. The vital signs machine can be contaminated by the blood, body fluids, or secretions of the client or other clients, and can harbor bacteria, viruses, or fungi. The dedicated vital signs machine can also ensure the accuracy, consistency, and availability of the measurements for the client.

Choice C reason: The client has a vase of fresh flowers on the table is an observation that requires further action by the nurse, because it is inappropriate and undesirable. The client with reduced immunity should not have a vase of fresh flowers on the table, as it can increase the exposure to pathogens or allergens that may cause infection or inflammation. The fresh flowers are a source of mold, pollen, or insects, which can trigger allergic reactions, respiratory distress, or skin irritation. The fresh flowers can also contain bacteria, viruses, or fungi, which can infect the client through inhalation, ingestion, or contact. The vase of fresh flowers should be removed from the room and replaced with artificial flowers, pictures, or cards.

Choice D reason: There is hand sanitizer by the door is not an observation that requires further action by the nurse, because it is appropriate and desirable. The client with reduced immunity should have hand sanitizer by the door, as it can promote the hand hygiene and infection prevention of the client and others. Hand sanitizer is a product that contains alcohol or other agents that can kill or reduce the number of pathogens or allergens that may cause infection or inflammation. Hand sanitizer should be used by the client, the staff, and the visitors before and after entering or leaving the room, or after touching any objects or surfaces in the room.

Choice A reason: This is an incorrect answer because a pathogenic infection is caused by a microorganism that can cause disease in a healthy host. Pathogens are usually able to overcome the host's immune defenses and cause symptoms and damage. Examples of pathogenic infections are strep throat, tuberculosis, and malaria.

Choice B reason: This is the correct answer because an opportunistic infection is caused by a microorganism that normally does not cause disease in a healthy host, but can take advantage of a weakened immune system and cause serious illness. Opportunistic infections are common and often lifethreatening complications of HIV infection, as the virus destroys the CD4 cells that help fight infections. Examples of opportunistic infections are pneumocystis pneumonia, candidiasis, and toxoplasmosis.

Choice C reason: This is an incorrect answer because a nosocomial infection is acquired in a health care setting, such as a hospital, clinic, or nursing home. Nosocomial infections are usually caused by microorganisms that are resistant to antibiotics and can spread easily among patients and staff. Examples of nosocomial infections are methicillinresistant Staphylococcus aureus (MRSA), Clostridioides difficile (C. diff), and urinary tract infections.

Choice D reason: This is an incorrect answer because a root cause infection is not a valid term in medical terminology. A root cause is the underlying factor or reason that leads to a problem or outcome. A root cause analysis is a process of identifying and addressing the root causes of a problem or event, such as an infection, to prevent recurrence and improve quality and safety.
