Answer to Question 1

B
Digoxin increases automaticity in the Purkinje fibers, which contributes to dysrhythmias caused by digoxin. Decreased automaticity in the AV node is a desired effect of digoxin. Digoxin does not increase automaticity in the SA node. It does not increase AV node conduction.

Answer to Question 2

B
The PCV13 should be given to all children under the age of 2 years and to all healthy children between ages 2 and 5 years, especially those who have conditions such as chronic lung disease that put them at high risk of serious pneumococcal disease. The Hib vaccine is only given up to age 15 months. The Rotavirus vaccine is not given after 32 weeks of age.
