A nursing preceptor is reviewing life expectancy in the twentieth century with a new nurse. The nurse should recognize that which of the following was most responsible for the dramatic increase in life expectancy during the twentieth century.

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: Scheduling energy-intensive activities at the time of day when the client has higher energy levels is the best activity plan for conserving the client's energy without compromising physical or mental health, as it allows the client to perform the tasks that require more effort and endurance when they feel more alert and capable. This can help the client to avoid fatigue, frustration, and injury, and to achieve their goals more effectively. The nurse should assess the client's individual preferences and patterns of energy fluctuation, and help them to prioritize and plan their activities accordingly.

Choice B reason: Scheduling all activities within a small block of time to allow the client a longer, uninterrupted rest period is not a good activity plan for conserving the client's energy without compromising physical or mental health, as it may cause the client to overexert themselves and deplete their energy reserves. This can lead to exhaustion, pain, and stress, and impair the client's recovery and quality of life. The nurse should advise the client to balance their activities with adequate rest periods throughout the day and to avoid doing too much or too little at once.

Choice C reason: Scheduling toilet breaks before and after any other planned activity is not a good activity plan for conserving the client's energy without compromising physical or mental health, as it may not be realistic or feasible for some clients. Some clients may have urinary or bowel problems that require them to use the toilet more frequently or urgently, such as incontinence, infection, or constipation. Forcing them to follow a rigid schedule may cause them discomfort, embarrassment, or complications. The nurse should assess the client's elimination needs and habits, and help them to manage their toileting needs in a comfortable and convenient way.

Choice D reason: Scheduling the client's hygiene activities and limiting visitors is not a good activity plan for conserving the client's energy without compromising physical or mental health, as it may neglect the client's social and emotional needs. Hygiene activities are important for maintaining the client's physical health and well-being, but they can also be tiring and challenging for some clients. Limiting visitors may reduce the noise and stimulation in the environment, but it can also isolate the client from their family and friends who can provide support and companionship. The nurse should assist the client with their hygiene needs as needed, and encourage them to interact with their visitors as tolerated.
