Which of the ff signs may be revealed by a visual examination in a client with tonsillar infection if group A streptococci is the cause?
Correct Answer: A
Rationale: The presence of white patches on the tonsils is a visual sign that may be revealed by a visual examination in a client with a tonsillar infection caused by group A streptococci. These white patches are known as exudates and can be a characteristic feature of streptococcal tonsillitis. These exudates may range in appearance from small white spots to larger patches that cover the tonsils. Additionally, other signs commonly associated with streptococcal tonsillitis may include swollen and red tonsils, fever, sore throat, and sometimes swollen lymph nodes in the neck. It is important to note that definitive diagnosis often requires laboratory testing such as a rapid strep test or throat culture to confirm the presence of group A streptococci.
