The nurse will give Amoxicillin 25 mg/kg as ordered. How many tablet(s) of Amoxicillin is needed if the medication is supplied as 500 mg tablets and the patient weighs 10 kg?

Choice A reason: Gloves reduce transmission but are not sufficient alone; improper use can spread microbes. Hand washing before and after patient contact is the most effective, universal method, so this is incorrect.

Choice B reason: Hand washing before and after patient contact is the most critical step to prevent microorganism transmission, as it removes pathogens from hands, the primary vector. This is the gold standard, making it correct.

Choice C reason: Cleaning the stethoscope is important but secondary to hand washing, which addresses the most common transmission route. Hands contact patients directly, so this is incorrect as the most important step.

Choice D reason: Protective eyewear prevents specific exposures but doesn’t address general microbial spread. Hand washing is the most effective, routine prevention method, so this is incorrect for the primary step.

Choice A reason: There is no standard “grade 5” in tonsil size grading. The scale typically ranges from 0 to 4+, with 4+ indicating tonsils touching or overlapping, making this an incorrect and non-standard documentation term.

Choice B reason: Grade 3 tonsils are enlarged, occupying about 75% of the pharyngeal space, but not touching. The described tonsils are touching, which corresponds to a higher grade, making grade 3 incorrect for this finding.

Choice C reason: Grade 2+ tonsils are moderately enlarged, taking up about 50% of the pharyngeal space. The tonsils touching indicate a more severe enlargement, aligning with a higher grade, making this an incorrect documentation choice.

Choice D reason: Grade 4+ tonsils are severely enlarged, touching or overlapping in the midline, as described. This matches the standard tonsil grading scale, where 4+ indicates maximal swelling, making this the correct documentation.
