Answer to Question 1

ANS: B
Hepatotoxicity is a serious potential problem in a patient receiving tizanidine, because the drug can cause liver damage. Baseline liver enzymes should be obtained before dosing and periodically thereafter. Analgesic anti-inflammatory drugs commonly are used in conjunction with centrally acting muscle relaxants, so using aspirin is not a concern. This drug does not contribute to malignant hyperthermia. Patients should be advised to avoid alcohol when taking this drug, but a history of occasional alcohol use is not a contraindication.

Answer to Question 2

ANS: C
Oxcarbazepine can cause clinically significant hyponatremia in 2.5 of patients. If oxcarbazepine is combined with other drugs that reduce sodium, the patient should be monitored. Signs of hyponatremia include nausea, drowsiness, confusion, and headache, and patients should be taught to report these symptoms. Increasing the dose of oxcarbazepine is not indicated. Rashes can indicate a serious drug reaction, and providers should be notified so that the oxcarbazepine can be withdrawn. Salt substitutes would compound the problem of hyponatremia.
