A man has been admitted to the hospital unit with a medical diagnosis of chronic obstructive pulmonary disease (COPD). He is receiving supplemental oxygen at 2 L/min via a nasal cannula. Which positioning technique will best assist him with breathing?

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.

Choice A reason: Calling a chaplain is not the priority nursing action for a client who is in critical condition and hypotensive. The chaplain may not be available or may not be able to provide adequate support to the spouse. This choice does not address the client’s urgent medical needs or the spouse’s emotional needs.

Choice B reason: Maintaining the client’s blood pressure is the priority nursing action for a client who is in critical condition and hypotensive. The nurse should monitor the client’s vital signs, administer fluids and medications, and provide oxygen as ordered. This choice addresses the client’s urgent medical needs and may prevent further complications.

Choice C reason: Providing the spouse a chair is not the priority nursing action for a client who is in critical condition and hypotensive. The spouse may not want to sit down or may not be able to stay calm. This choice does not address the client’s urgent medical needs or the spouse’s emotional needs.

Choice D reason: Asking the client’s spouse to explain what happened is not the priority nursing action for a client who is in critical condition and hypotensive. The spouse may not be able to recall or communicate the details of the event. This choice does not address the client’s urgent medical needs or the spouse’s emotional needs.
