A client taking linaclotide reports severe watery diarrhea, dizziness, and near-syncope; blood pressure is 84/50 mm Hg. Which action is the priority?
1Take an extra linaclotide capsule to establish a more predictable bowel pattern.
2Continue the same dose and restrict fluids until the diarrhea stops.
3Hold linaclotide and obtain urgent assessment and ordered fluid and electrolyte replacement.✓ Correct answer
4Delay reporting the episode unless constipation returns during the next month.
Explanation
Severe diarrhea with hypotension and near-syncope indicates clinically important volume loss and requires suspension, rehydration, and urgent assessment.
Quick answer Respond to linaclotide-associated severe diarrhea and hypoperfusion.
Why this is correct Postmarketing severe diarrhea has been associated with syncope, hypotension, and electrolyte abnormalities requiring hospitalization or intravenous fluids.
Easy analogy or mental picture Use a closed medication-safety loop: identify the exposure, connect the new findings, interrupt further harm, support physiology, and verify the response over time.
Memory hook Exposure, interaction, toxicity pattern, immediate action, serial reassessment.
NCLEX decision rule Choose the action that reduces the most immediate medication-related risk while preserving monitoring and escalation.
Why the other choices are wrong Options that continue the exposure, treat only one symptom, or delay reassessment leave the toxic process active.
Medication safety reviewVerify the indication, route, interacting medicines, current respiratory and gastrointestinal findings, authorized action, and measurable follow-up.
