CBRN Burn Prevention, Quality Improvement & Research

Question 1

What is the maximum water heater temperature generally recommended to reduce scald injuries in the home?

Accepted Answer

120°F (49°C)

Answer

At 140°F (60°C), a full-thickness scald can occur in about 3 seconds in adults and faster in young children. Setting the heater to 120°F (49°C) or lower greatly extends the time to injury.

Question 2

Which activity is an example of primary burn prevention?

Accepted Answer

Community campaign promoting working smoke alarms and home escape plans

Answer

Primary prevention stops injuries before they happen through education, environmental change, and legislation. Treatment and rehabilitation are secondary and tertiary prevention.

Question 3

If a person's clothing catches fire, which instruction should the nurse teach in a school fire-safety program?

Accepted Answer

Stop, drop, and roll

Answer

Running feeds the flames with oxygen. Stopping, dropping to the ground, covering the face, and rolling smothers the fire and limits injury.

Question 4

In the hierarchy of evidence used for evidence-based nursing practice, which source is generally strongest?

Accepted Answer

Systematic review or meta-analysis of randomized controlled trials

Answer

Systematic reviews of RCTs combine multiple high-quality studies and reduce bias, so they sit at the top of the evidence hierarchy. Expert opinion and case reports are weaker.

Question 5

A burn unit wants to lower its central line-associated bloodstream infection (CLABSI) rate. Which approach best matches a quality improvement framework such as PDSA?

Accepted Answer

Plan a bundle change, do a small test, study the results against the baseline, and act to adopt or adjust

Answer

PDSA (Plan-Do-Study-Act) cycles use small tests of change and data measurement to decide whether to adopt, adapt, or abandon an intervention.
