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 public health nurse is a nurse who works to improve the health and well-being of populations and communities, not specific workplaces. A public health nurse may focus on disease prevention, health promotion, environmental health, or emergency preparedness.

Choice B reason: A community nurse specialist is a nurse who has advanced education and training in a specific area of nursing practice, such as gerontology, oncology, or mental health. A community nurse specialist may work in various settings, such as hospitals, clinics, or schools, to provide specialized care and education to clients and families.

Choice C reason: A nurse clinician is a nurse who has expertise in clinical practice, research, and education. A nurse clinician may work in academic or clinical settings, such as universities, hospitals, or research centers, to develop and implement evidence-based practices and policies.

Choice D reason: An occupational health nurse is a nurse who works to protect and promote the health and safety of workers in various industries, such as manufacturing, mining, or construction. An occupational health nurse may provide services such as health assessment, injury prevention, emergency response, or wellness programs.

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.
