Worked practice questions

Early symptoms of most sexually transmitted infections include

  1. high fever and chills
  2. joint pain and rash
  3. cough and breathlessness
  4. itching and fluid discharge
Show answer and solution

Correct answer: D. itching and fluid discharge

1. Early symptoms of most of these infections are minor. 2. They include itching, fluid discharge, slight pain and swellings in the genital region. 3. Because the signs are mild, infected people often delay seeking care. 4. Fever, joint pain and cough point towards other groups of illness entirely. _Source: syllabus Biology Ch3 'Reproductive Health', section 3.4_

Why do sexually transmitted infections often remain undetected for long in females?

  1. They are often asymptomatic
  2. They resolve without any treatment
  3. They cannot be diagnosed by any test
  4. They only appear after menopause
Show answer and solution

Correct answer: A. They are often asymptomatic

1. Infected females may often be asymptomatic. 2. With no symptom to prompt a visit, the infection is not detected for a long time. 3. Mild early symptoms and the social stigma attached deter people from timely detection. 4. Untreated infection can then progress to pelvic inflammatory disease, ectopic pregnancy or infertility. 5. This is precisely why screening matters more than waiting for a complaint. _Source: syllabus Biology Ch3 'Reproductive Health', section 3.4_

An untreated sexually transmitted infection can lead to

  1. progressive pulmonary fibrosis
  2. pelvic inflammatory disease
  3. pernicious anaemia of infancy
  4. peptic ulcer of the stomach
Show answer and solution

Correct answer: B. pelvic inflammatory disease

1. Delayed detection allows a sexually transmitted infection to progress. 2. Complications include pelvic inflammatory diseases, abortions and still births. 3. Ectopic pregnancies, infertility and even cancer of the reproductive tract can follow. 4. Each of those is a reproductive tract consequence, which is what makes early cure so important. 5. Anaemia, fibrosis and ulcers arise from unrelated disease processes. _Source: syllabus Biology Ch3 'Reproductive Health', section 3.4_
