A 60 year-old female client has multiple sclerosis accompanied by muscle spasticity. The client has responded well to dantrolene 200 mg PO daily in divided doses. What assessment finding should the nurse prioritize for communication to the client's provider?
The client's most recent laboratory results show an upward trend in AST and ALT levels Explanation: An increase in liver enzyme levels could indicate the onset of hepatocellular damage, which is a high risk in female clients of this age. The provider must be made aware of this immediately. The client's lack of motivation and apparent despair should be addressed by the nurse, but may be able to be addressed independently by the nurse. As well, these issues are less time-dependent than a decrease in liver function. A weight gain of 1.5 lbs. over 48 hours is not outside the range of usual fluctuations in fluid balance.

A nurse is caring for a male patient who has a spinal cord injury due to a motorcycle accident. He has been taking dantrolene (Dantrium) for 2 weeks. The nurse will monitor:
alanine aminotransferase and total bilirubin levels. Explanation: The nurse will monitor alanine aminotransferase and total bilirubin levels, because a serious adverse effect of dantrolene is drug-induced hepatitis. The nurse will also educate the patient and family concerning signs and symptoms of hepatitis. Prothrombin time and partial thromboplastin time would be monitored for someone taking an anticoagulant, not for someone taking dantrolene. Urine specific gravity is part of a urinalysis and would be used to assess urinary function, which is not affected by dantrolene use. Follicle-stimulating hormone level is important to the female reproductive system and would not be assessed in a male.
