**Core Concept**
Minute ventilation is the volume of air that moves in and out of the lungs per minute, calculated as the product of tidal volume and respiratory rate. It is a critical parameter in assessing respiratory function and is used in various clinical settings, including mechanical ventilation and respiratory monitoring.

**Why the Correct Answer is Right**
To calculate minute ventilation, we multiply the tidal volume (TV) by the respiratory rate (RR). The normal tidal volume is approximately 500 mL, but this can vary depending on factors such as age, sex, and body size. Assuming a normal tidal volume of 500 mL and a respiratory rate of 12 breaths/min, we can calculate the minute ventilation as follows: Minute ventilation = TV x RR = 500 mL/breath x 12 breaths/min = 6000 mL/min or 6 L/min.

**Clinical Pearl / High-Yield Fact**
Remember that minute ventilation is a critical parameter in assessing respiratory function, and it can be affected by various factors, including respiratory rate, tidal volume, and airway resistance. A high minute ventilation may indicate respiratory distress or failure, while a low minute ventilation may indicate respiratory depression or failure.

**Correct Answer: D. 6 L/min**
