A nurse is providing care to a client who is Immunocompromised. Which of the following should the nurse identify as a possible source of infection?

A. The cause of death is typically determined and documented by the attending physician or coroner, not the nurse.
B.While this information might be included in other parts of the medical record prior to the death, it is not required in postmortem documentation.
C. The nurse should verify that advance directives were followed, but the actual copy of the advance directives does not need to be included in the postmortem documentation. These should already be part of the client’s medical record.
D. Documenting the location of the identification tag is important for proper identification of the body after death. This ensures that the body is correctly identified during transfer to the morgue or funeral home.

Since the client is prescribed home oxygen at 1 to 2 L/min, a nasal cannula is the most appropriate device for oxygen delivery in this scenario. A nasal cannula consists of two small prongs that are inserted into the client's nostrils, delivering oxygen directly into the nasal passages. It is a comfortable and commonly used device for low-flow oxygen therapy.

Petroleum jelly is not directly related to oxygen therapy and is not typically required for the use of a nasal cannula.

A reservoir bag is not typically used with a nasal cannula. It is a component of a different oxygen delivery system called a non-rebreather mask, which is used for high-flow oxygen therapy or in emergency situations.

An oxygen mask is also not typically used with a nasal cannula. It is a separate oxygen delivery device that covers the client's mouth and nose, delivering oxygen at a higher flow rate. Masks may be used in situations where higher concentrations or flows of oxygen are required, or when the client is unable to tolerate or use a nasal cannula effectively.
