A medical assistant is instructed to gather vitals from a patient who has pyrexia. The assistant should expect which of the following vital signs to be outside the expected reference range?
Heart rate
Temperature
Respiratory rate
Blood pressure
The Correct Answer is B
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.

Correct Answer is A
Explanation
A. Stress test: A stress test, or exercise stress test, involves monitoring the heart's activity with an EKG while the patient exercises on a treadmill or stationary bike. This test assesses how the heart performs under physical stress.
B. Holter monitor: A Holter monitor is a portable EKG device worn by the patient for 24-48 hours to continuously record heart activity in their daily life, not during exercise.
C. Echocardiogram: An echocardiogram uses ultrasound to visualize the heart's structures and is not performed while the patient is exercising.
D. Cardiac event monitor: A cardiac event monitor is used to record heart activity when the patient experiences symptoms, typically worn for weeks to months, and is not specifically for exercise testing.
Correct Answer is A
Explanation
Correct answer: A
A. Ensure the otoscope is in the room. Ensuring that the otoscope and other necessary equipment are in the room is an important step in preparing the room for a physical examination.
B. Replace the half-full sharps containers. Sharps containers should be replaced when they are three-quarters full, not necessarily when they are half-full. This action, while important, is not specific to preparing for a general physical examination.
C. Obtain preauthorization from insurance. Preauthorization is an administrative task that is not directly related to preparing an examination room.
D. Sterilize counter surfaces in the room. Cleaning and disinfecting counter surfaces is important for infection control but typically would have been done after the last patient. This action is less directly related to preparing for a general physical exam compared to ensuring the necessary equipment is present.
