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 B

Explanation

Choice A reason: Advance directives outline future care wishes, unlike consent for immediate treatment. This conflates distinct legal documents, misinforming the client.

Choice B reason: Advance directives ensure autonomy, letting clients dictate care preferences pre-surgery. This accurately conveys their purpose in healthcare decision-making.

Choice C reason: Lawyer approval isn’t required; forms are legally valid with witnesses. This overstates complexity, deterring clients from creating directives.

Choice D reason: Directives apply to all, not just life-threatening cases. They’re proactive for any surgery, so this limits their broad applicability.

A. The client's extremity should be elevated after the cast is applied. B. The client should use a hair dryer on a warm setting to relieve itching inside the cast. C. The client should keep the cast covered until it is dry. D. The client can shower with the cast after 24 hr.

Correct Answer is A

Explanation

Choice A reason: Elevation reduces swelling post-cast application, enhancing circulation. It’s a key step to prevent edema and discomfort in the right arm.

Choice B reason: Hair dryers risk burns or softening plaster; scratching tools are safer. This is incorrect and dangerous advice for cast care management.

Choice C reason: Covering delays drying, trapping moisture in plaster. It needs air exposure to harden, so this contradicts proper cast maintenance.

Choice D reason: Showering after 24 hr wets plaster, weakening it. Casts require protection from water, making this an inaccurate care instruction.
