A nurse is assisting with teaching a class about the importance of fire safety. Which of the following hazards should the nurse include as an example of the leading cause of residential fires?
Placing a space heater 5 ft from bed
Smoking in bed
Leaving the stove on
Lack of smoke detectors
The Correct Answer is B
Choice A reason: A space heater 5 feet from a bed is relatively safe if unobstructed, not a leading fire cause. Scientifically, heaters rank lower than smoking, as ignition requires closer flammable contact, making this less statistically significant per fire safety data.
Choice B reason: Smoking in bed is a top cause of residential fires, as embers easily ignite bedding. Scientifically, NFPA data show it’s a leading ignition source due to direct fuel contact, causing rapid flame spread, making it a critical hazard to highlight.
Choice C reason: Leaving the stove on causes kitchen fires, but smoking surpasses it in residential fatalities. Scientifically, unattended cooking ranks high, yet smoking’s bedroom context increases risk of sleeping victims, amplifying danger per fire incidence studies.
Choice D reason: Lack of smoke detectors increases fire deaths, not ignition. It’s a detection failure, not a cause. Scientifically, this affects outcomes, not initiation, making it irrelevant to identifying the leading hazard source per fire safety causation statistics.

Correct Answer is C
Explanation
Choice A reason: Detailed explanations suit older children, not toddlers with limited comprehension. Simple reassurance works better, making this less effective for exam preparation.
Choice B reason: Starting with immunizations increases fear and resistance in toddlers. Less invasive steps first build trust, so this heightens distress unnecessarily.
Choice C reason: Letting toddlers handle equipment reduces fear through familiarity. This age-appropriate tactic eases anxiety, preparing them effectively for a calm physical examination.
Choice D reason: Fully undressing upfront can distress toddlers, lowering cooperation. Gradual exposure during the exam maintains comfort, making this an unsuitable initial step.
Correct Answer is C
Explanation
Choice A reason: Constipation isn’t a primary effect of disulfiram-alcohol reaction, which causes acetaldehyde buildup, triggering vasodilation and nausea, not gut motility issues. Scientifically, this reaction targets cardiovascular and systemic responses, lacking evidence for significant gastrointestinal stasis as a monitored outcome in this scenario.
Choice B reason: Dry skin isn’t linked to disulfiram-alcohol interaction, which induces flushing and sweating from acetaldehyde toxicity, not dehydration. Scientifically, the reaction affects vascular and autonomic systems, producing moist, not dry, skin responses, making this an unrelated finding for monitoring here.
Choice C reason: Hypotension occurs in disulfiram-alcohol reaction as acetaldehyde dilates vessels, dropping blood pressure. This cardiovascular effect, alongside tachycardia, is a key sign to monitor, aligning with scientific understanding of the drug’s inhibition of aldehyde dehydrogenase, causing systemic distress.
Choice D reason: Urinary retention isn’t a typical disulfiram-alcohol effect; the reaction focuses on vasodilation, nausea, and hypotension from acetaldehyde. Scientifically, autonomic overstimulation may occur, but bladder dysfunction isn’t a primary outcome, making this less critical to monitor than cardiovascular collapse.
