Answer to Question 1

ANS: A
Drugs that act on beta2 receptors activate glyconeogenesis in the liver causing increased blood glucose. Selective beta2 drugs act on beta2 receptors only and not on beta1 receptors, so they do not cause increased blood pressure or increased heart rate. Adrenergic agonists cause decreased GI motility.

Answer to Question 2

ANS: B, D, F
Patients with an intact, functioning gastrointestinal tract will benefit from enteral nutrition. Patients with extensive burns will need total parenteral nutrition (TPN) to prevent negative nitrogen balance. Patients with Crohn's disease and gluten enteropathy have malabsorption problems and will need TPN.
