A community health nurse is assigned to identify activities that are a part of the prevention/mitigation phase of the disaster management cycle. Which of the following activities should the nurse identify as being in the prevention/mitigation phase?

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: Giving the patient extra time to perform activities is an appropriate action by the nurse. Bradykinesia is a symptom of Parkinson's disease that causes slow and reduced movement, making it difficult for the patient to initiate and complete tasks. The nurse should respect the patient's autonomy and dignity, and allow them to do as much as they can by themselves, without rushing or interfering.

Choice B reason: Teaching the client to walk more quickly when ambulating is not an appropriate action by the nurse. Bradykinesia can affect the patient's gait and balance, making them prone to falls and injuries. The nurse should not encourage the patient to walk faster than their ability, but rather provide them with assistive devices, such as a cane or walker, and ensure a safe environment.

Choice C reason: Placing the client on a low-protein, low-calorie diet is not an appropriate action by the nurse. Bradykinesia does not require any specific dietary modifications, unless the patient has other comorbidities, such as diabetes or hypertension. The nurse should ensure that the patient has adequate nutrition and hydration, and avoid foods that may interfere with their medication absorption, such as high-fiber or high-fat foods.

Choice D reason: Completing passive range-of-motion exercises daily is not an appropriate action by the nurse. Bradykinesia can cause muscle stiffness and rigidity, which can limit the patient's range of motion and flexibility. The nurse should encourage the patient to do active range-of-motion exercises, which involve moving their own joints to their full extent, rather than passive ones, which involve someone else moving their joints for them. Active exercises can help maintain muscle strength and joint mobility and prevent contractures and deformities.
