Answer to Question 1

ANS: B
Tachycardia is a sign of hypoxemia. Once the hypoxemia is corrected, their heart rate typically improves.

Answer to Question 2

For patients with acute asthma, the PEFR is the most frequently used parameter to assess airway resistance.

Peak expiratory flow rate (PEFR) (L/min) 350-600 (normal) 75-100 (critical value)
