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 C

Explanation

Choice A reason: Weight gain, not loss, follows nicotine cessation due to appetite increase. Withdrawal heightens metabolism briefly, but loss isn’t a typical manifestation.

Choice B reason: Diaphoresis occurs during acute withdrawal but isn’t primary. Nicotine’s absence disrupts sleep more consistently, making this a less dominant symptom.

Choice C reason: Insomnia is a hallmark of nicotine withdrawal, from CNS stimulation loss. It disrupts sleep regulation, a common, persistent issue in quitting smokers.

Choice D reason: Diarrhea can occur but is less frequent than insomnia in withdrawal. Nicotine’s absence more reliably affects sleep over GI motility initially.

A. Educate the infant's guardians about exchange transfusion. B. Administer granulocyte colony-stimulating factor. C. Initiate droplet precautions. D. Monitor the infant's lymphocyte count.

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.
