Final answer:
A health care worker might notice fever, chills, or body aches in a patient with the flu through the sense of touch, as well as assess muscular strength and fatigue.
Step-by-step explanation:
A health care worker can use their sense of touch to make observations about someone who has the flu, such as Mr. Poweres. They may notice increased body temperature (fever), chills, or body aches through palpation which is when they touch or press on parts of the body to feel for abnormalities. Furthermore, by providing resistance against the patient's limbs, the health care worker can assess muscular strength and fatigue that may be associated with the flu. In cases where a patient exhibits neurological symptoms, as seen in the provided examples, the sense of touch can help determine sensory deficits or response to stimuli such as the feeling of pins and needles.
