Choice B rationale
Tuberculosis is an airborne infectious disease. An N95 respirator mask is necessary to protect against inhaling airborne droplets that may contain the bacteria, especially in healthcare settings.
Choice C rationale
Scarlet fever is a bacterial infection caused by group A Streptococcus. It spreads through respiratory droplets, but standard surgical masks are usually adequate. An N95 respirator is not required.

Correct Answer is B
Explanation
Choice A rationale
Breaking needles in half before disposal is dangerous and not recommended. It increases the risk of needlestick injuries and exposure to bloodborne pathogens.
Choice B rationale
Not recapping needles, especially after drawing arterial blood gas (ABG) specimens, is a recommended practice to prevent needlestick injuries. This reduces the risk of accidental puncture during the recapping process.
Choice C rationale
Recapping needles and placing them in a wastebasket is unsafe and increases the risk of needlestick injuries and improper disposal of medical waste, which can expose others to bloodborne pathogens.
Choice D rationale
Placing uncapped needles directly into a puncture-proof container after use is a safe practice, but the question specifically asks about preventing needlestick injuries during the handling of ABG specimens, where recapping should be avoided.
