Answer to Question 1

C
Feedback:
Conduction System of the Heart: SA (sinoatrial) node (pacemaker); AV (atrioventricular) node; bundle of His (AV bundle); right and left bundle branches; Purkinje fibers to muscles of ventricles.

Answer to Question 2

A
Feedback:
A client with mental illness may not be in a state to intake fluid independently, and may require the nurse's assistance. A client who is feeling nauseated for food can be provided with alternate food; clients with a broken limb or a skin disorder may not require assistance from the nurse to meet their fluid needs.
