The nurse is caring for a client with rheumatoid arthritis one day after shoulder surgery. What would prompt the nurse to call the provider immediately?

Choice A reason: Determine whether it is temporary or permanent is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Determining whether the compromised immunity is temporary or permanent is an important assessment, but it should be done after ensuring the safety and infection prevention of the client. Compromised immunity can be temporary or permanent, depending on the cause, such as medication, disease, or genetic disorder.

Choice B reason: Take the client's vital signs every four hours is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Taking the client's vital signs every four hours is an important monitoring, but it should be done after ensuring the safety and infection prevention of the client. Vital signs can indicate the general health status and the presence of infection or inflammation, such as fever, tachycardia, or hypotension.

Choice C reason: Teach the family members to receive the flu shot annually is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Teaching the family members to receive the flu shot annually is an important education, but it should be done after ensuring the safety and infection prevention of the client. The flu shot is a vaccine that can protect the family members and the client from influenza, which can be a serious and potentially fatal infection for people with compromised immunity.

Choice D reason: Wash hands before entering the client's room is the nurse's priority action for a client with compromised immunity, because it is the most urgent and relevant. Washing hands before entering the client's room is a basic and essential infection prevention measure, which can protect the client from exposure to pathogens that can cause infection. People with compromised immunity have a weakened or impaired immune system, which makes them more susceptible and vulnerable to infection.

Choice A reason: Inflammation is not an example of a client's primary defense to infection. Inflammation is a secondary defense to infection, which is activated after the primary defense has been breached. Inflammation is a complex process that involves the release of chemical mediators, the dilation of blood vessels, the increase of blood flow, the migration of white blood cells, and the formation of exudate. Inflammation aims to contain, neutralize, and eliminate the infectious agent and to repair the damaged tissue.

Choice B reason: Fever is not an example of a client's primary defense to infection. Fever is a secondary defense to infection, which is activated after the primary defense has been breached. Fever is an elevation of the body temperature above the normal range, which is usually 36.5 to 37.5 degrees Celsius or 97.7 to 99.5 degrees Fahrenheit. Fever is a systemic response to infection that is regulated by the hypothalamus, which is the part of the brain that controls the body's thermostat. Fever enhances the immune system's activity and inhibits the growth of some pathogens.

Choice C reason: Phagocytosis is not an example of a client's primary defense to infection. Phagocytosis is a secondary defense to infection, which is activated after the primary defense has been breached. Phagocytosis is a process that involves the engulfment and destruction of foreign particles, such as bacteria, by specialized cells, such as macrophages and neutrophils. Phagocytosis is a type of cellular immunity that eliminates the infectious agent and prevents its spread.

Choice D reason: Intact skin is an example of a client's primary defense to infection. Intact skin is the first and most important line of defense against infection, as it forms a physical barrier that prevents the entry of pathogens into the body. Intact skin also has chemical and biological properties that resist infection, such as the acidic pH, the secretion of sebum and sweat, and the presence of normal flora. Intact skin protects the underlying tissues and organs from infection and injury.
