A nurse is caring for a patient with pyelonephritis. What does the nurse identify as the most common cause?
- A. Escherichia coli
- B. Neisseria gonorrhoeae
- C. Chlamydia trachomatis
- D. Candida albicans
Correct Answer: A
Rationale: The correct answer is A: Escherichia coli. In pyelonephritis, bacteria typically ascend from the lower urinary tract to the kidneys. E. coli is the most common cause due to its prevalence in the gastrointestinal tract and ability to cause urinary tract infections. Neisseria gonorrhoeae and Chlamydia trachomatis are more commonly associated with sexually transmitted infections, not pyelonephritis. Candida albicans is a fungal infection and is not a common cause of pyelonephritis.
