1. What situation could impair a patient's respiratory status by directly damaging the central chemoreceptors of the body?

2. What is the actual site of attachment of oxygen in the red blood cell?

3. The EMT would document an FDO2 level when the patient is:

4. Which statement about the ventilation/perfusion (V/Q) ratio in a healthy person is true?

5. Which process of ventilation is correctly adhering to Boyle's law as it relates to ventilation?

6. You are caring for a 66-year-old male patient who is severely dehydrated. How does severe dehydration affect the cardiovascular system?

7. A patient is hemorrhaging internally within his colon, which in turn is impairing perfusion to the cells of his body. Aside from the bleeding, the patient has no other problems. In this scenario, the problem impairing adequate perfusion would be:

8. Which condition would directly compromise the average patient's cardiac output?

9. A drop in blood pressure below a critical threshold is a threat to the body because it directly impairs:

10. Perfusion is best described as:

11. What is baroreceptors' role in the body?

12. A patient's brain cells are undergoing anaerobic metabolism. As a result, those cells:

13. What is the protective mechanism underlying a narrowed pulse pressure?

14. Which condition would most likely account for an elevated CO2 level in a patient's body?

15. A 20-year-old female patient has called 911 for chest pain. On scene, you find that she has shallow breathing with an SpO2 reading of 91% on room air. She states she was in a car crash yesterday and diagnosed in the hospital with broken ribs. Her pain is right where the ribs are broken, and she rates the pain as a 10/10. Breath sounds are present bilaterally. In this situation, the EMT should attribute the hypoxia to which cause?

16. The EMT would most likely see a narrowed pulse pressure in a patient who:

17. What is the best description of minute ventilation?

18. What is required for normal perfusion to occur?

19. A patient who is hypoxic has a pulmonary disease that involves low lung compliance. With this condition, you realize that:

20. What is the primary stimulus to breathe in human beings without pulmonary diseases?

21. When a patient has a narrowed pulse pressure, what is occurring?

22. Failure of the sodium-potassium pump can result in:

23. For a patient who relies on the hypoxic drive to breathe, the respiratory rate will increase when:

24. What is the result of an opening developing that allows air into the space between the visceral and parietal pleura of the thorax?

25. A patient has a blood pressure of 140/98 mmHg. What can the EMT ascertain from this reading?
