A nurse advises a client with osteoporosis to have three servings of milk or dairy products daily. Which of the following levels of prevention is being used by the nurse?

Choice A reason: A negative-pressure isolation room is not a suitable room for a client who has scabies. A negative-pressure isolation room is used for clients who have airborne infections, such as tuberculosis or chickenpox. It prevents the contaminated air from escaping the room and infecting other people.

Choice B reason: A positive-pressure isolation room is not a suitable room for a client who has scabies. A positive-pressure isolation room is used for clients who have compromised immune systems, such as those undergoing bone marrow transplants or chemotherapy. It prevents the outside air from entering the room and exposing the client to germs.

Choice C reason: A private room is a suitable room for a client who has scabies. Scabies is a skin infection caused by tiny mites that burrow under the skin and cause intense itching and rash. Scabies can spread easily through direct skin-to-skin contact or sharing personal items, such as clothing or bedding. A private room can prevent the transmission of scabies to other clients or staff.

Choice D reason: A semi-private room with a client who has pediculosis capitis is not a suitable room for a client who has scabies. Pediculosis capitis is an infestation of head lice that feeds on human blood and causes itching and irritation on the scalp. Pediculosis capitis can also spread easily through direct contact or sharing personal items, such as combs or hats. Sharing a room with another client who has pediculosis capitis can increase the risk of cross-infection and complicate the treatment of both conditions.

Choice A reason: The integumentary system is a portal of entry for anthrax because the bacteria can enter through cuts or abrasions on the skin. This is called cutaneous anthrax, and it is the most common and least deadly form of anthrax infection.

Choice B reason: The endocrine system is not a portal of entry for anthrax because the bacteria do not affect the glands or hormones of the body. The endocrine system is mainly involved in regulating metabolism, growth, development, and reproduction.

Choice C reason: The central nervous system is a portal of entry for anthrax because the bacteria can spread to the brain and spinal cord from other parts of the body. This is called meningeal anthrax, and it is a rare and fatal complication of anthrax infection.

Choice D reason: The renal system is not a portal of entry for anthrax because the bacteria do not infect the kidneys or urinary tract. The renal system is mainly involved in filtering waste products and excess fluids from the blood.

Choice E reason: The respiratory system is a portal of entry for anthrax because the bacteria can be inhaled into the lungs. This is called inhalation anthrax, and it is the most deadly form of anthrax infection.
