Final answer:
The nurse should clarify the provider's prescription for performing nasopharyngeal suctioning on the client who has epistaxis.
Step-by-step explanation:
The nurse should clarify the provider's prescription for performing nasopharyngeal suctioning on the client who has epistaxis. Epistaxis refers to a nosebleed, which can be a sign of nasal irritation or injury. Nasopharyngeal suctioning may aggravate the bleeding and worsen the condition. Therefore, it is important for the nurse to confirm with the provider whether it is safe to proceed with suctioning in this case.
