The nurse has documented the following wound assessment: “Shallow, open, reddened ulcer with no drainage on the center of the right heel.” What stage is the wound?

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: 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.
