Step-by-step explanation:
The nurse should clarify the prescription for Meperidine with the healthcare provider when providing care for a client diagnosed with a sickle cell crisis. Meperidine, also known as Demerol, is an opioid analgesic that is not considered the first-line medication for treating acute sickle cell pain. Instead, other opioids like Hydromorphone, Morphine, or Codeine are commonly used.
