Final answer:
The nurse's action reflects evidence-based practice, which combines clinical expertise with research and patient values. It's a response to maintain homeostasis in the body. Precision in measurement tools is crucial in healthcare to ensure accurate diagnosis and treatment. option a
Step-by-step explanation:
The nurse's action of taking the client's temperature after they report chills and feeling unwell is an example of evidence-based practice. This approach to patient care integrates clinical expertise with the best available research evidence and patient values. Shivering, which can occur even when the body temperature has not dropped, is a response triggered by the hypothalamus in the brain. The hypothalamus, receiving signals from the immune system, acts to raise the body's temperature to create an environment less favorable to pathogens. This is an example of how the brain integrates the immune system and nervous system to maintain homeostasis.
Real-world applications, such as using a thermometer to measure a fever, highlight the importance of precision. In the scenario with a sick child, a thermometer with a high uncertainty of 3.0°C could provide a temperature reading that is not accurate enough to be useful, which could be critical in a healthcare setting.
In the clinical focus scenario, the health-care provider is concerned about Jeni's high fever and symptoms because they are typical signs of an infection. Despite Jeni's healthy lifestyle and up-to-date immunizations, the consumption of raw milk, which can contain harmful bacteria, prompts the healthcare provider to order a blood test to investigate a possible infection.
