Answer to Question 1

ANS: A, B, C, E
Cardiac output is the product of stroke volume and heart rate (CO = SV  HR). Afterload and contractility are components of stroke volume. Hemoglobin is not related to cardiac output but does impact tissue oxygenation.

Answer to Question 2

ANS: A, B, C, D
An enlarged liver in a child can be indicative of heart failure or fluid overload from congenital heart defects. Assessing for respiratory distress, listening to heart and lung sounds, and calculating I&O will all give information related to cardiac function. Bowel movements are not related.
