  B. Actuate the MDI directly down the ETT.
  C. Use a small-volume nebulizer to aerosolize the drug.

Answer to Question 1

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: Patients who experience an asthmatic attack while being mechanically ventilated should receive systemic IV corticosteroids. Generally, inhaled corticosteroids are not indicated for patients receiving mechanical ventilation. However, asthma patients who are not having an acute episode, but are maintained on inhaled corticosteroids, may be an exception.

Answer to Question 2

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: 2 receptors in skeletal muscles are stimulated by 2 agonists, causing muscle tremors. Pulmonary vasodilatation in blood vessels previously constricted shunts blood to poorly perfused alveoli, causing the Pao2 to decrease. 1 receptors of the myocardium are stimulated by 2 agonists, causing tachycardia. 2 adrenergic bronchodilators can increase blood glucose and insulin levels, and decrease serum potassium concentrations.
