Answer to Question 1
ANS: B
Chlorzoxazone is a centrally acting muscle relaxant; however, its hepatic side effects can be severe and life threatening, and its effectiveness is minimal, so the risks of using this agent outweigh the benefits. Analgesic anti-inflammatory drugs are used as part of drug therapy in a patient with muscle spasms caused by localized muscle injury. Metaxalone is a centrally acting muscle relaxant that can be used with caution and with periodic liver function evaluation. Whirlpool baths are useful adjuncts to drug therapy.
Answer to Question 2
ANS: A
An overdose of baclofen can produce coma and respiratory depression, so the nurse would be correct to suspect overdose in this patient. Respiratory support is essential to prevent a fatal outcome. There is no antidote for baclofen overdose. Diazepam would not be indicated, because seizures are not a result of baclofen overdose and may further depress respirations. An electrocardiogram is not indicated for this patient.
