The nurse receives the result of a patient's pulmonary functions tests. The respiratory rate is 14 breaths per minute and the tidal volume is 540 ml. The nurse correctly calculates the client's minute ventilation as:
1. 7560 milliliters/minute.
2. 14 milliliters/minute.
3. 540 milliliters/minute.
4. 32,400 milliliters/minute.
7560 milliliters/minute.
Rationale: Minute ventilation is calculated by multiplying the respiratory rate times the tidal volume: 14 540 = 7560. The rates of 14, 540, and 32,400 ml/minute are not correct.
