Final answer:
When testing for streptococcal pharyngitis, implement droplet precautions to prevent the spread of the bacteria.
Step-by-step explanation:
When testing for streptococcal pharyngitis, the recommended transmission-based precautions to implement are D. Droplet precautions. Streptococcal pharyngitis, or strep throat, is caused by the bacteria Streptococcus pyogenes.
