Final answer:
The nurse should obtain information about the client's a. history of inflammatory bowel disorders before administering a high volume saline enema.
Step-by-step explanation:
The nurse should obtain information about the client's history of inflammatory bowel disorders (option a) before administering a high volume saline enema. This is because clients with inflammatory bowel disorders may have specific needs or precautions that need to be considered when administering the enema.
Although the reason for administering the enema and the client's feelings about having an enema are important, they are not the most crucial pieces of information to obtain before administering the enema. On the other hand, allergies to medications are important to know, but the first priority is to gather information about the client's history of inflammatory bowel disorders.
