A nurse is caring for a client who presents to the emergency room in sickle cell crisis. Which of the following medications should the nurse anticipate administering?

A. Laxatives are not typically used for sickle cell crisis unless the client is experiencing constipation, which is unrelated to the crisis itself. B. Thyroid replacement medications are used for hypothyroidism and would not be a first-line treatment for sickle cell crisis. C. Diuretics may be used in conditions like heart failure or kidney disease, but they are not indicated for sickle cell crisis and may worsen dehydration. D. Pain medications are the correct intervention during a sickle cell crisis. The crisis involves severe pain due to the sickling of red blood cells blocking blood flow to tissues. Opioids like morphine and hydromorphone are commonly administered to manage the severe pain.
