## Question

A client receives irinotecan. Classify each finding by the medication-safety decision it supports.

|  | Early cholinergic pattern | Late diarrhea pattern | Urgent complication escalation |
| --- | --- | --- | --- |
| Abdominal cramping and diarrhea begin during the infusion |  |  |  |
| Diaphoresis and lacrimation accompany the infusion reaction |  |  |  |
| Profuse watery diarrhea begins 36 hours after treatment |  |  |  |
| Late diarrhea is accompanied by orthostatic hypotension |  |  |  |
| Temperature 38.5 C with severe neutropenia and diarrhea |  |  |  |
| Abdominal distention with absent bowel sounds |  |  |  |

## Explanation

Diarrhea with sweating, cramping, and lacrimation during infusion is an early cholinergic pattern; diarrhea beginning more than 24 hours later is late toxicity; dehydration, fever, ileus, or neutropenia requires urgent escalation.

## In-depth explanation

Quick answer
Distinguish early cholinergic symptoms, late diarrhea, and high-risk complications.

Why this is correct
Early symptoms may respond to authorized atropine, while late diarrhea requires prompt antidiarrheal therapy, fluid and electrolyte support, and escalation for fever, ileus, or severe neutropenia.

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.References

## Clinical scenario

Medication safety review
Verify the indication, route, interacting medicines, current respiratory and gastrointestinal findings, authorized action, and measurable follow-up.
