This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Physiology
Calculate the Alveolar ventilation per minute of a patient with respiratory rate 14/min, tidal volume of 500 ml with a vital capacity 7000 ml 
Select and explain. 
A. 4900 ml, B. 2000 ml, C. 7700 ml, D. 7000 ml
A: 4900 ml
Answer: A: 4900 ml 
Explanation: Alveolar ventilation= Respiratory rate X (Tidal volume – Dead space)
Respiratory rate provided in question- 14 per minute
Tidal Volume- 500ml
Dead Space- 150 ml 
AV= 14 (500-150)= 14 X 350 = 4900ml/min = 4.9 L/min
