A patient presents with a fever and flank pain. Microscopic analysis of the urine reveals
bacteria at a concentration above 10,000 colony-forming units (CFUs) per milliliter. You
perform a leukocyte esterase (LE) test, and it is positive. What is the diagnosis? -
ANS-pyelonephritis
Which statement regarding normal microbiota of the urinary and reproductive systems is

The physician performs a pelvic exam, which reveals the presence of an abnormal thin,
watery vaginal discharge and inflammation of the cervix. The physician then palpates
the abdomen (examines by touch and pressure) and finds that the uterus, fallopian
tubes, and ovaries are enlarged and tender. The physician takes a swab sample of the
cervix and sends it to the laboratory to determine the causal organism. Light microscopy
and simple staining of the sample in the lab reveal an organism with a very unique life
cycle. The organism is classified as gram-negative, but it stains very poorly compared to
other classic gram-negative STI pathogens. The stain shows both a nonreplicating,
extracellular infectious elementary body and a replicating, noninfectious reticulate body
inside mucosal cells from the cervical epithelium swab. Based on the symptoms and
these new laboratory findings, which of the following would be the most -
ANS-chlamydia
The two most common STI organisms associated with PID in the United States are
Chlamydia trachomatis and Neisseria gonorrhoeae. There are many similarities
between these STIs. Which of the following statements comparing chlamydia and
gonorrhea are true?
Select all statements that are TRUE. - ANS-Chlamydia and gonorrhea can infect a
patient and be transmitted without causing obvious symptoms.
Patients may be coinfected with both gonorrhea and chlamydia.
Chlamydia is found more often in women, whereas gonorrhea is found more often in
men.
Chlamydia PID is just part of the overall spectrum of disease caused by Chlamydia
organisms. Even though we now understand more about STIs and their complications,
we are still exploring how the organisms "branch out" beyond just a single infection.
Which of the following diseases have Chlamydia infection as an etiology?
