A community health nurse is conducting an educational program on various environmental pollutants. The nurse should emphasize that clients who have which of the following disorders are especially vulnerable to ozone effects?

Choice A reason: Monitoring vital signs and neurological status frequently is a priority intervention for a client who has experienced a hemorrhagic stroke, as it helps to detect any changes in the client's condition and guide appropriate treatment. Hemorrhagic stroke is a medical emergency that occurs when a blood vessel in the brain ruptures and causes bleeding into the brain tissue. This can lead to increased intracranial pressure, cerebral edema, and brain damage. Therefore, the nurse should monitor the client's blood pressure, pulse, respiration, temperature, level of consciousness, pupil reaction, motor function, and sensory function frequently and report any abnormalities to the health care provider.

Choice B reason: Maintaining strict bed rest to minimize cerebral blood flow is not a priority intervention for a client who has experienced a hemorrhagic stroke, as it may not prevent further bleeding or improve the client's outcome. In fact, strict bed rest may increase the risk of complications such as deep vein thrombosis, pulmonary embolism, pneumonia, pressure ulcers, and muscle atrophy. The nurse should follow the health care provider's orders regarding the client's activity level and position. The nurse should also provide adequate hydration, nutrition, skin care, and comfort measures to the client.

Choice C reason: Administering anticoagulant medications as prescribed is not a priority intervention for a client who has experienced a hemorrhagic stroke, as it may worsen the bleeding and increase the risk of intracranial hemorrhage. Anticoagulant medications are used to prevent or treat ischemic stroke, which is caused by a blood clot that blocks a blood vessel in the brain. However, anticoagulant medications are contraindicated in hemorrhagic stroke, as they interfere with the blood's ability to clot and stop the bleeding. The nurse should avoid giving any medications that may affect coagulation or platelet function to the client unless ordered by the health care provider.

Choice D reason: Assisting the client with active range of motion exercises is not a priority intervention for a client who has experienced a hemorrhagic stroke, as it may not improve the client's neurological function or prevent complications. Active range of motion exercises are performed by the client with or without assistance from the nurse to maintain joint mobility and muscle strength. However, these exercises are not indicated in the acute phase of hemorrhagic stroke, as they may increase intracranial pressure or cause pain or discomfort to the client. The nurse should consult with the physical therapist before initiating any exercise program for the client.

Choice A: Reviewing communicable disease statistics. This is incorrect because this is an example of descriptive epidemiology, not analytic epidemiology. Descriptive epidemiology describes the distribution and patterns of health events in populations, such as the frequency, location, and time of occurrence.

Choice B: Tracking locations where family violence is increasing. This is incorrect because this is also an example of descriptive epidemiology, not analytic epidemiology. Descriptive epidemiology tracks the trends and variations of health problems in different groups or areas.

Choice C: Describing population characteristics for healthy older citizens. This is incorrect because this is another example of descriptive epidemiology, not analytic epidemiology. Descriptive epidemiology provides information about the demographic and social factors that influence health outcomes.

Choice D: Identifying factors contributing to childhood obesity. This is correct because this is an example of analytic epidemiology. Analytic epidemiology investigates the causes and associations of health events in populations, such as the risk factors, exposures, or interventions that affect health outcomes. Analytic epidemiology often uses comparison groups to test hypotheses and draw conclusions.
