C.Q. was recently exposed to group A hemolytic Streptococcus and subsequently developed a pharyngeal infection. His clinic examination reveals an oral temperature of 102.3°F, skin rash, dysphagia, and reddened throat mucosa with multiple pustules. He complains of sore throat, malaise, and joint stiffness.

True
The nurse is swabbing a patient's throat to test for streptococcal pharyngitis. The nurse must understand that tests such as this differ in the probability that they will be positive for a condition when applied to a person with the condition; this probability is termed sensitivity. (True/False)
True.
