## Question

A client receiving dexmedetomidine develops HR 42/min and BP 78/44 mm Hg. Which actions are appropriate? Select exactly 4 responses.

Select exactly 4 responses.

1

Increase the infusion because the client can be aroused with stimulation.

2

Decrease or stop the infusion according to the prescribed protocol and notify the authorized clinician.

3

Continue continuous heart rate, blood pressure, and oxygen monitoring.

4

Prepare prescribed supportive interventions such as fluids, leg elevation, pressor therapy, or an anticholinergic.

5

Give a rapid intravenous bolus of dexmedetomidine to stabilize sedation.

6

Assess for hypovolemia and concurrent negative chronotropic medications.

## Explanation

Dexmedetomidine-related hypotension and bradycardia may require decreasing or stopping the infusion, continuous monitoring, assessment of contributors, and supportive treatment.

## In-depth explanation

Quick answer
Select infusion reduction, continuous monitoring, contributor assessment, and prescribed support.

Why this is correct
The label links dexmedetomidine to hypotension, bradycardia, and sinus arrest. Management may include decreasing or stopping the infusion, fluids, leg elevation, pressors, or anticholinergics.

Easy analogy or mental picture
Take pressure off the brake before adding more force to a slowing system.

Memory hook
Slow pulse plus low pressure: reduce the driver and support circulation.

NCLEX decision rule
Treat hemodynamic intolerance first and remember that arousability alone is an expected feature, not proof of inadequate sedation.

Why the other choices are wrong
A rapid bolus can worsen bradycardia or sinus arrest, and increasing the rate ignores instability.References

## Clinical scenario

Sedation hemodynamics
Trend heart rate, rhythm, blood pressure, volume status, interacting drugs, infusion rate, and oxygenation.
