A patient receiving Pressure Control ventilation suddenly develops worsening bronchospasm. What change would most likely be observed?

A patient is receiving Volume Assist/Control ventilation. Overnight the peak inspiratory pressure increases from 28 cmH2O to 42 cmH2O while tidal volume remains unchanged. What is the primary concern?

A patient receiving Volume Assist/Control repeatedly triggers breaths and develops respiratory alkalosis. Which intervention is MOST appropriate?

Three point charges are positioned as follows: q1 is at (0.00 m, 0.00 m), q2 is at (1.20 m, 0.00 m), and q3 is at (1.20 m, 1.60 m). If q1 = 1.00 µC, q2 = 2.00 µC, and q3 = 3.00 µC, what is the magnitude of the force on q2?  (k = 9×109 Nm2/C2)
