What is an infectious disease that can be transmitted directly from one person to another?

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.

Choice A reason: Postponing daily bed bath is not appropriate for reducing the risk of a friction and shear injury. Bed bath is a hygiene measure that helps to keep the skin clean and dry and prevent infection. Friction and shear are caused by the rubbing and pulling of the skin against the bed surface, not by the bed bath itself.

Choice B reason: Elevating the client’s head of the bed to 45 degrees is not appropriate for reducing the risk of a friction and shear injury. In fact, this may increase the risk as the client may slide down the bed due to gravity and cause more friction and shear on the skin. The head of the bed should be kept at the lowest possible angle, preferably less than 30 degrees, unless contraindicated by the client’s condition.

Choice C reason: Caregiver independently slides the client up in bed is not appropriate for reducing the risk of a friction and shear injury. This may cause more damage to the skin as the caregiver may exert excessive force and drag the client’s skin along the bed surface. The caregiver should use a draw sheet or a slide board to lift and reposition the client with the help of another person.

Choice D reason: Use a mechanical lift to reposition the client every 2 hours is the most appropriate intervention for reducing the risk of a friction and shear injury. A mechanical lift is a device that helps to transfer and reposition the client safely and comfortably. It reduces the friction and shear on the skin by lifting the client off the bed surface and avoiding any sliding or dragging. It also prevents the caregiver from injuring themselves by lifting the client manually. The client should be repositioned every 2 hours to relieve the pressure on the skin and prevent pressure ulcers.
