A nurse is educating a client about dantrolene (Dantrium). Which of the following statements indicate the appropriate therapeutic use of this medication?

A. Dantrolene (Dantrium) is used to treat malignant hyperthermia, a life-threatening condition triggered by certain anesthetic agents. It works by inhibiting calcium release from the sarcoplasmic reticulum in muscle cells, reducing muscle rigidity and preventing further complications. B. Dantrolene is not used for treating status epilepticus; other medications such as benzodiazepines are used for that purpose. C. Dantrolene is not used for overactive bladder; medications like anticholinergics or beta-3 agonists are typically prescribed for this condition. D. While dantrolene can relieve muscle spasms, it is primarily used for conditions like malignant hyperthermia and spasticity from conditions like cerebral palsy or spinal cord injury, rather than just for muscle injury.
