Which term denotes a regular and slow respiratory rate?

• A. Bradypnea
• B. Tachypnea
• C. Apnea
• D. Hyperpnea

Answer: (A)

The main idea is identifying terminology for breathing patterns. Bradypnea refers to a slower-than-normal breathing rate, with the rhythm remaining regular. In adults, normal breathing is roughly 12–20 breaths per minute; when the rate drops below about 12 while the breaths stay regular, that’s bradypnea. The other terms describe different patterns: tachypnea is rapid breathing, apnea is a temporary halt in breathing, and hyperpnea is an increased depth and rate of breathing usually in response to exercise or metabolic demand. Since the question specifies a regular and slow rate, bradypnea best fits.
