What is a priority teaching point when discharging a client who will be taking newly prescribed baclofen?

Rationale: A. "Check your temperature often because this drug can mask infection.": Baclofen is a centrally acting muscle relaxant that primarily affects GABA receptors in the spinal cord to reduce spasticity. It does not possess significant antipyretic or immunosuppressive properties that would mask infection, so routine temperature monitoring for this reason is not a primary teaching focus. B. "Do not perform complex tasks when taking this medication.": Baclofen commonly causes central nervous system depression, including drowsiness, dizziness, and decreased alertness. These effects can impair coordination and judgment, increasing the risk of accidents when driving or operating machinery, making safety precautions a key discharge teaching point. C. "This medication may increase rigidity and limit your range of motion.": Baclofen is prescribed specifically to reduce muscle spasticity and improve mobility by inhibiting excitatory neurotransmission in the spinal cord. An increase in rigidity would indicate ineffective therapy or another underlying issue rather than an expected effect of the medication. D. "Liver function tests need to be done routinely to monitor toxicity.": Unlike some muscle relaxants, baclofen is primarily excreted unchanged by the kidneys and does not commonly cause hepatotoxicity. Routine liver function monitoring is not a standard requirement.
