The client is scheduled for a functional assessment using the Functional Independence Measure (FIM). The client asks the nurse, "What is the
purpose of the FIM?" Which nursing response is appropriate?

Choice A reason: Natural history of disease is not an approach that explains the factors that allow the reproduction and spread of infectious disease, but rather a description of how a disease progresses over time from exposure to outcome in the absence of intervention.

Choice B reason: Health promotion is not an approach that explains the factors that allow the reproduction and spread of infectious disease, but rather a process of enabling people to increase control over and improve their health through education, empowerment, and policy changE.

Choice C reason: Levels of prevention are not an approach that explains the factors that allow the reproduction and spread of infectious disease, but rather a classification of interventions based on their timing and purpose in relation to disease occurrencE.

Choice D reason: Epidemiologic triangle is an approach that explains the factors that allow the reproduction and spread of infectious disease, by identifying and analyzing three elements: agent (the cause of disease), host (the person who gets sick), and environment (the conditions that affect transmission).

Choice A reason: Performing carotid massage is not an appropriate action for the nurse to take because it can worsen the client's condition by decreasing the blood flow to the brain, causing further ischemia or hemorrhagE. Carotid massage is a technique that involves applying pressure to the carotid artery to slow down the heart rate, which can be dangerous for clients who have a strokE.

Choice B reason: Calling for help is an appropriate action for the nurse to take because it can initiate the rapid response team and activate the stroke protocol, which can improve the client's outcome and survival. The nurse should also assess the client's vital signs, neurological status, and time of symptom onset, and report them to the health care provider.

Choice C reason: Providing the client with water to test the gag reflex is not an appropriate action for the nurse to take because it can increase the risk of aspiration and pneumonia, which can complicate the client's recovery and prognosis. The nurse should avoid giving anything by mouth to the client until their swallowing ability is evaluated by a speech therapist or a swallow study.

Choice D reason: Administering thrombolytics is not an appropriate action for the nurse to take because it requires a physician's order and confirmation of the type and cause of stroke by a computed tomography (CT) scan or magnetic resonance imaging (MRI) scan. Thrombolytics are drugs that dissolve blood clots and restore blood flow, which can be beneficial for clients who have ischemic stroke, but harmful for clients who have hemorrhagic strokE.
