- infection is 2:1 in favour of men
Neisseria Gonorrhoea has been shown to have some antibiotic resistance. What is the primary reason for this?
1 - antigens are specific to tissue infected
2 - mixes with chlamydia
3 - antigens change every time it infects a host
4 - all of the above
4 - all of the above

2 - prostatitis
3 - Rectal gonorrhoea:
4 - Pharyngeal gonorrhoea
5 - PID
5 - PID

2 - Dysuria
3 - Lower abdominal pain
4 - urethral discharge
5 - Abnormal vaginal bleeding (intermenstrual or postcoital)
4 - urethral discharge

To diagnose Gonorrhoea a swab can be grown on culture. Which of the following media needs to be used?
1 - blood agar
2 - chocolate agar
3 - Xylose Lysine Deoxycholate agar
4 - mycoplasm agar
2 - chocolate agar
Which of the following is the gold standard for diagnosing Gonorrhoea?
1- nucleic acid amplification tests (NAATs)
2 - urinalysis
3 - gram positive staining
4 - serology
1- nucleic acid amplification tests (NAATs)
- essentially PCR for bacterial genetic info
Nucleic acid amplification tests (NAATs) is the 1st line test for diagnosing gonorrhoea. Which 2 are the best sample to take from a women using NAATs?
1 - cervical swab
2 - vaginal swab
3 - first void urine
4 - hysteroscopy biopsy
1 - cervical swab
2 - vaginal swab
Vaginal is best though
Nucleic acid amplification tests (NAATs) is the 1st line test for diagnosing chlamydia and gonorrhoea. What is the best sample to take from a man using NAATs?
1 - cervical swab
2 - vaginal swab
3 - first void urine
4 - hysteroscopy biopsy
3 - first void urine
If a swab of a patient with gonorrhoea was added to a slide and placed under a microscope following gram staining, what would we expect to see?
1 - diplococci with a purple colour
2 - diplococci with a pink colour
3 - coccobacilli with a purple colour
4 - coccobacilli with a pink colour
2 - diplococci with a pink colour
- infection typically shows that the pink diplococci are inside neutrophils
When managing a patient who has been diagnosed with gonorrhoea, which of the following must be implemented:
1 - Partner Notification & Treatment
2 - Education, health promotion
3 - Abstinence – 7 days AND until partner treated
4 - Antibiotic treatment
5 - Condoms
6 - Prevention and risk reduction
7 - all of the above
7 - all of the above
What is the 1st line medication when treating a patient with a confirmed diagnosis of gonorrhea?
1 - cephalexin 1g
2 - ceftriaxone 1g
3 - doxycycline 100mg
4 - benzathine penicillin 10mg
2 - ceftriaxone 1g
- given stat via IM
- followed by oral ciprofloxacin 500mg in a single dose
- cephalasporin that are able to inhibit cell wall synthesis
