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: Offering multiple choices overwhelms a delirious client, whose impaired cognition struggles with decisions. Scientifically, delirium reduces attention and processing, so simplifying options aids comfort, making this counterproductive to managing their acute confusional state effectively.
Choice B reason: Alternating caregivers disrupts continuity, worsening disorientation in delirium. Consistent faces aid recognition, reducing anxiety. Scientifically, familiarity stabilizes perception in acute confusion, making this detrimental to the client’s need for a predictable environment during recovery.
Choice C reason: Avoiding fears ignores emotional distress, potentially increasing agitation in delirium. Addressing concerns gently can calm. Scientifically, unaddressed anxiety exacerbates confusion, so this neglects a holistic approach needed for managing the client’s psychological state effectively.
Choice D reason: Reminding of day and time reorients the client, countering delirium’s disorientation. Frequent cues anchor perception, aiding recovery. Scientifically, this aligns with evidence-based care, as repeated orientation reduces confusion’s impact, supporting cognitive stabilization in acute delirium management.
Correct Answer is D
Explanation
Choice A reason: Cantaloupe is potassium-rich, about 400 mg per cup, due to its fruit sugar content. It’s unsuitable for low-potassium diets, as it elevates serum levels significantly.
Choice B reason: Orange juice contains around 500 mg potassium per cup, a high amount. Its citric nature doesn’t offset this, making it inappropriate for potassium restriction.
Choice C reason: Sweet potato has over 500 mg potassium per serving, concentrated in its starchy flesh. It’s a poor choice for minimizing potassium in electrolyte imbalances.
Choice D reason: Baked chicken breast offers less than 300 mg potassium per serving, far lower than fruits or tubers. It’s the best option for a low-potassium diet here.
