TRUE or FALSE: When one is health y and at rest, Heart Beat Rate (heartbeats per minute) is twice (two times) the Breathing Rate (breaths per minute). What is the systolic pressure of a patient whose blood pressure is 120/70? A. 190 B. 120 C. 70 D. 50 Which respiratory volume is defined as the amount of air that can be forcibly expired/exhaled after a normal tidal inspiration/inhalation? A. expiratory reserve volume. B. inspiratory reserve volume. C. tidal volume. D. vital capacity TRUE or FALSE: The "first" heart sound is produced when the atrioventricular valves close. One can hold one's breath for a specific amount of time after one breathes normally while at rest. How long can one typically hold one's breath after one hyperventilates? A. The same amount of time as at rest. B. A longer period of time than at rest. C. A shorter period of time than at rest. What apparatus used to auscultate heart and respiratory sounds? A. Spirometer. B. Sohvamomanometer. C. Stethoscope. D. Ventilator. Which term is defined as "the alternate expansion and recoil of an artery that can be palpated during systole and diastole of the heart? A. apical. B. pulse. C. vital capacity. D. tid al volume

Explanation / Answer

1. The Korotkoff sound is heard during the measurement of blood pressure. The first korotkoff sound is heard during the measurement of systolic blood pressure and the fourth korotkoff sound is heard during the diastolic blood pressure.

2. The level of carbon dioxide decreases during hyperventilation. This process is also called over breathing which occurs when the rate and quantity of alveolar ventilation of carbon dioxide exceed the body's production of carbon dioxide. When the alveolar ventilation increases, more carbon dioxide will be removed from the blood stream. This causes the concentration of carbon dioxide to decrease.

3. The statement is True. A typical respiratory rate of breaths per minute for a healthy adult at rest is around 15-20 breaths per minute, while a normal resting heart rate is around 40 beats per minute.

4. The systolic blood pressure would be equal to 120 which refers to the amount of pressure in the arteries during the contraction of heart muscle.

5. It is called as Expiratory reserve volume. This is measured by the amount of air that can be forcefully exhaled after a normal tidal volume exhalation.

6. The statement is true. The first heart sound is produced by the closing of atrioventricular valves i.e. Mitral and Tricuspid valves.
