## Question

A client with severe hypercalcemia of malignancy has received calcitonin for 4 days, but the calcium response has plateaued. Which order should the nurse clarify?

## Option

1. Continue renal and volume-status monitoring during treatment.
2. Review ongoing antiresorptive therapy for sustained calcium control.
3. Continue calcitonin alone indefinitely despite the plateau. **✔ Correct answer**
4. Reassess symptoms and serial corrected calcium results.

**Correct answer: 3**

## Explanation

Calcitonin has a rapid effect but should be limited to a short course because tachyphylaxis develops. Sustained control requires appropriate antiresorptive therapy rather than indefinite calcitonin monotherapy.

## In-depth explanation

Quick answer
Question prolonged calcitonin monotherapy after the response plateaus.

Why this is correct
The client still needs symptom, calcium, renal, and volume reassessment while longer-acting therapy addresses ongoing malignancy-driven calcium release.

Easy analogy or mental picture
Treat every infusion as a controlled clinical system: verify the product and access, recognize a changing cue, stop preventable exposure, stabilize the client, and confirm the response.

Memory hook
Product, access, compatibility, infusion cue, protective action, and reassessment.

NCLEX decision rule
Choose the action that prevents the most immediate infusion-related harm while preserving vascular access and the ordered diagnostic evidence.

Why the other choices are wrong
Options that restart a suspect product, bypass a safety device, force an occluded tube, or delay reassessment can convert a reversible warning into serious harm.References

## Clinical scenario

Blood product, nutrition, and intravenous-fluid safety review
Verify the product, prescription, route, access device, filter or tubing, compatibility, baseline findings, emerging adverse cues, response plan, and measurable follow-up.
