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 D
Explanation
Choice A reason: Difficulty swallowing isn’t a typical pain sign from epidural failure; it suggests throat or nerve issues unrelated to disc pain. Scientifically, this lacks connection to spinal analgesia efficacy, as herniated disc pain manifests elsewhere, not in pharyngeal function.
Choice B reason: Constipation may result from opioids in epidurals, not unrelieved pain. It’s a side effect, not a pain indicator. Scientifically, bowel changes reflect medication impact, not disc pain intensity, making this an unreliable marker for epidural effectiveness.
Choice C reason: Urinary retention is an epidural side effect from nerve blockade, not a direct pain signal. Scientifically, it indicates spinal anesthesia depth, not failure to relieve herniated disc pain, distinguishing it from pain-specific behavioral cues.
Choice D reason: Clenched teeth reflect facial tension, a common involuntary response to unrelieved spinal pain. Scientifically, this aligns with pain behavior studies, as muscle guarding and grimacing indicate persistent disc-related discomfort, signaling epidural inadequacy effectively.
Correct Answer is D
Explanation
Choice A reason: Exchange transfusion treats severe conditions like hyperbilirubinemia, not HIV. It’s irrelevant for a 10-month-old’s ongoing viral management needs.
Choice B reason: Granulocyte colony-stimulating factor boosts neutrophils, not lymphocytes, in neutropenia. HIV targets CD4 cells, making this an ineffective intervention here.
Choice C reason: Droplet precautions suit respiratory infections, not HIV, which spreads via blood/body fluids. Standard precautions suffice, so this isn’t needed.
Choice D reason: Monitoring lymphocyte (CD4) count tracks HIV progression in infants. It guides antiretroviral therapy, a critical ongoing management step at 10 months.
