IncorrectQuestion 2 0 / 2 pts Carcinoma in situ is characterized by which changes? Cells have broken through the local basement membrane. Cells have invaded immediate surrounding tissue. Cells remain localized in the glandular or squamous cells. Cellular and tissue alterations indicate dysplasia.

These early stage cancers are localized to the epithelium and have not broken through the local basement membrane or invaded the surrounding tissue. Dysplasia refers to changes in mature cell structure. Question 3 2 / 2 pts Which laboratory test is considered adequate for an accurate and reliable diagnosis of gonococcal urethritis in a symptomatic man? Ligase chain reaction (LCR) Gram-stain technique Polymerase chain reaction (PCR) DNA testing Microscopic evaluation of Gram-stained slides of clinical specimens is deemed positive for Neisseria gonorrhoeae if gram-negative diplococci with the typical “kidney bean” morphologic appearance are found inside polymorphonuclear leukocytes. Such a finding is considered adequate for the diagnosis of gonococcal urethritis in a symptomatic man. The other options are not relevant to the diagnosis of this condition.
