A provider requests that a medical assistant arrange personal care for an adult patient who needs help with meal preparation and personal care. Which of the following services should the assistant contact?

A. Chemistry: Chemistry typically involves tests related to chemical components of blood, such as electrolytes and enzymes, not hematological tests.
B. Serology: Serology involves the study of blood serum and its components, often related to immune responses and infections, not hematological tests.
C. Hematology: Hematology is the laboratory section responsible for performing tests related to blood components, including CBC (Complete Blood Count) and erythrocyte sedimentation rate (ESR).
D. Microbiology: Microbiology focuses on the study of microorganisms, including bacteria and viruses, not hematological tests.

A. Heart rate: Pyrexia (fever) often leads to an increased heart rate as the body attempts to regulate its temperature. Therefore, heart rate may be higher than normal.
B. Temperature: Pyrexia indicates an elevated temperature, so the temperature would be outside the expected reference range due to the fever.
C. Respiratory rate: While fever can sometimes affect the respiratory rate, it is not as directly impacted as heart rate or temperature. Respiratory rate may be slightly elevated but is less consistently affected compared to heart rate and temperature.
D. Blood pressure: Fever does not typically cause significant changes in blood pressure. It is less likely to be outside the expected reference range compared to heart rate and temperature.
