Answer to Question 1

C
Feedback:
Pacemaker cells are found in the SA node of the heart, which controls cardiac contraction and relaxation, therefore controlling the overall heart rate. If the SA node malfunctions, a pacemaker would be indicated. Hypertension, increased pulse pressure, and onset of oncotic pressure would not be an indication for pacemaker insertion.

Answer to Question 2

B
Feedback:
Loss of bowel and bladder control is an adverse effect of cholinergic agents that would cause stress in a child. Diarrhea and increased salivation are also adverse effects. Increased appetite is not associated with these drugs. Children are more likely to have gastrointestinal (GI) upset that could result in a decrease in appetite.
