A client has been administered lorazepam for acute seizure control. Which clinical manifestation is the nurse's priority to monitor for immediately following the administration?

A. "Monitor your blood pressure since hypertension can occur.": Baclofen primarily acts as a central nervous system muscle relaxant by stimulating GABA-B receptors. While it can cause hypotension in some cases, hypertension is not a common adverse effect. Blood pressure monitoring for high readings is generally not required unless indicated by comorbid conditions.

B. "Do not take antihistamines with this medication.": Baclofen can cause central nervous system depression, including drowsiness, dizziness, and impaired coordination. Concomitant use of other CNS depressants, such as antihistamines, can increase the risk of excessive sedation and respiratory depression. Clients should avoid combining these medications.

C. "Stop taking this medication immediately if you are drowsy.": Sudden discontinuation of baclofen, especially after prolonged use, can precipitate severe withdrawal symptoms, including hallucinations, seizures, and increased spasticity. Drowsiness is a common, expected side effect and should be monitored, but the medication should not be stopped abruptly.

D. "Expect muscle spasticity to worsen initially.": Baclofen is prescribed to reduce muscle spasticity in multiple sclerosis. While some transient effects such as mild weakness may occur initially, spasticity should gradually decrease rather than worsen. Worsening spasticity is not a typical expectation when starting therapy.

A. Both manifest fistula formation: Fistula formation is characteristic of Crohn’s disease due to transmural inflammation, which affects all layers of the intestinal wall. Ulcerative colitis typically involves only the mucosal and submucosal layers, making fistulas uncommon.

B. Both begin in the rectum: Ulcerative colitis usually starts in the rectum and may extend proximally in a continuous pattern. Crohn’s disease can affect any part of the gastrointestinal tract from mouth to anus, often in a patchy, segmental distribution.

C. Both require frequent surgery: While surgical intervention may be necessary in both diseases for complications, the frequency differs. Ulcerative colitis may require colectomy in severe cases, whereas Crohn’s disease often requires surgery for obstruction or fistula management.

D. Both attack the digestive tract: Both ulcerative colitis and Crohn’s disease are types of inflammatory bowel disease (IBD) characterized by chronic inflammation of the gastrointestinal tract. Although the pattern, location, and depth of inflammation differ, the shared pathophysiology involves immune-mediated attacks on the digestive tract.
