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

Answer and Explanation

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 A

Explanation

Choice A reason: Shoulder harnesses at shoulder level secure the infant, distributing crash forces evenly. Scientifically, this aligns with safety standards, preventing spinal injury by stabilizing the torso, a critical car seat feature per biomechanical crash studies for optimal protection.

Choice B reason: A cushion under the head risks airway obstruction or spinal misalignment in crashes. Scientifically, added padding alters manufacturer design, increasing injury risk, as car seats are engineered for direct fit without extras per safety regulations.

Choice C reason: A 90-degree angle is upright, risking airway collapse in newborns with weak necks. Scientifically, a 30-45-degree recline supports breathing and spinal alignment, making this unsafe per pediatric and crash safety evidence.

Choice D reason: Airbags in the front seat can fatally injure infants in rear-facing seats via rapid inflation. Scientifically, back-seat placement avoids this, as airbag force exceeds infant tolerance, contradicting safety mandates for car seat positioning.

A. "My baby will receive three doses of the meningococcal immunization before kindergarten." B. "I should not feed my baby anything for 2 hours prior to an immunization." C. "I should expect my baby to have a high fever for 24 hours after an immunization." D. "My baby will receive the rotavirus immunization orally."

Correct Answer is D

Explanation

Choice A reason: Meningococcal vaccine starts at 11-12 years, not infancy; three doses by kindergarten is incorrect. Scientifically, this misaligns with CDC schedules, as 2-month-olds get other vaccines (e.g., DTaP), showing misunderstanding of immunization timing.

Choice B reason: No feeding restriction exists for immunizations; fasting isn’t required. Scientifically, nutrition supports immune response, and this contradicts standard practice, as feeding doesn’t affect vaccine efficacy or safety, indicating a preparation misconception.

Choice C reason: High fever for 24 hours isn’t typical; mild fever may occur but not guaranteed. Scientifically, this exaggerates normal vaccine reactions (e.g., low-grade fever), misrepresenting expected immune responses, suggesting inaccurate outcome expectations.

Choice D reason: Rotavirus vaccine is oral at 2 months, per CDC schedule, aligning with its live attenuated form. Scientifically, this reflects correct administration knowledge, as it targets gut immunity, showing the guardian understands this immunization’s delivery accurately.
