Choice A rationale

Performing hand hygiene frequently and consistently is the most effective way to prevent the spread of pathogens during patient care. Hand hygiene is the single most important measure to reduce the transmission of harmful germs and prevent health care-associated infections.

Choice B rationale

Properly disposing of contaminated equipment is important in preventing the spread of pathogens, but it is not the most effective measure. While it is crucial to handle and dispose of contaminated equipment properly, hand hygiene is the most effective measure in preventing the spread of pathogens.

Choice C rationale

Discarding used syringes in appropriate containers is a standard safety measure in healthcare settings, but it is not the most effective way to prevent the spread of pathogens during patient care. While it is important for preventing needlestick injuries and the spread of bloodborne pathogens, hand hygiene is the most effective measure in preventing the spread of pathogens.

Choice D rationale

Changing soiled linens daily for patients with draining wounds is a part of standard wound care and infection control, but it is not the most effective way to prevent the spread of pathogens during patient care. Hand hygiene remains the most effective measure in preventing the spread of pathogens.

Choice A rationale

Broth is a clear liquid that can help replace sodium and chloride lost through diarrhea. However, it does not contain the necessary amounts of other electrolytes such as potassium and bicarbonate, which are also commonly lost in diarrhea.

Choice B rationale

Apple juice is not a good choice for a child with acute diarrhea. It is high in sugars and can worsen diarrhea. It also does not contain the electrolytes needed to replace those lost through diarrhea.

Choice C rationale

Cherry gelatin is not a suitable choice. While it is a clear liquid that can help with hydration, it does not contain the necessary electrolytes to replace those lost through diarrhea. It is also high in sugars, which can worsen diarrhea.

Choice D rationale

Pedialyte is the best choice for a child with acute diarrhea who reports that he is thirsty. It is a rehydration solution specifically designed to replace fluids and electrolytes lost through diarrhea.
