A nurse teaches a patient with newly diagnosed Type 1 Diabetes about sick-day management. Which statement indicates a need for further teaching?

Rationale:

A. Baclofen is a centrally acting skeletal muscle relaxant that targets the GABA-B receptors in the spinal cord, inhibiting excitatory neurotransmission. By reducing the frequency and severity of muscle spasms, stiffness, and hypertonicity, it helps improve mobility, ADLs, and overall comfort in patients with MS. This demonstrates correct understanding of the therapeutic purpose of the medication.

B. Both baclofen and alcohol are CNS depressants, which can lead to additive effects such as excessive drowsiness, dizziness, hypotension, or impaired coordination, increasing the risk of falls or accidents. Avoiding alcohol ensures patient safety, especially during initiation or dose adjustments.

C. Stopping baclofen abruptly is dangerous. Sudden discontinuation can cause rebound spasticity, severe muscle rigidity, hallucinations, seizures, fever, and even life-threatening complications. Safe discontinuation requires a gradual tapering schedule under medical supervision. This statement indicates the patient does not understand the importance of safe medication management and the physiologic consequences of sudden withdrawal.

D. Drowsiness, fatigue, and generalized weakness are common CNS-related adverse effects of baclofen, particularly at the start of therapy or after dose increases. Educating patients about these effects helps them anticipate changes, avoid risky activities (e.g., driving or operating machinery), and adhere to the regimen while monitoring tolerance.

Rationale:

A. On-off syndrome is a common complication of long-term Levodopa-Carbidopa therapy in Parkinson’s disease. Clients experience sudden, unpredictable fluctuations between periods of good mobility (“on” periods) and severe motor impairment or immobility (“off” periods). This occurs due to pulsatile dopaminergic stimulation and the short half-life of Levodopa, which leads to inconsistent dopamine receptor activation in the basal ganglia. Recognition and management (e.g., adjusting dosing schedules, using controlled-release formulations, or adding adjunct medications) are key to improving functional mobility.

B. Withdrawal syndrome refers to symptoms that occur after abrupt discontinuation of a medication, such as sudden worsening of Parkinsonian symptoms or life-threatening complications with drugs like baclofen. In this case, the client is still taking Levodopa, so this is not a withdrawal effect.

C. Rebound tremor refers to a temporary increase in tremor after a medication wears off or is rapidly discontinued. While related to motor fluctuations, it is not synonymous with the full immobility episodes seen in on-off syndrome. Rebound tremor is a specific component of motor fluctuation, not the broader phenomenon described here.

D. Acute dystonia involves sustained, involuntary muscle contractions causing abnormal postures, often occurring shortly after starting or increasing certain medications (e.g., antipsychotics). The client’s sudden “off” periods of immobility are not dystonic postures but generalized motor blockade, making dystonia an inappropriate description.
