Step 1: Understanding the Concept.
Notice the key detail in the question, this retroverted uterus was found on a routine check, with no mention of pain, backache, or any other complaint.
Step 2: Key Formula or Approach.
Retroversion of the uterus is common and, in most women, just a harmless variation in anatomy with a uterus that moves freely. This papers answer key treats pessary treatment as correct for this scenario.
Step 3: Detailed Explanation.
A pessary is used to support a retroverted uterus, including cases picked up incidentally, and is the answer marked correct in this source.
Ventral suspension surgery is an even bigger step, reserved for long standing symptoms that have already failed conservative care, so it clearly does not fit as well here.
Postural exercises can help a mobile retroverted uterus reposition itself when there are mild symptoms.
Many current textbooks would instead favor no treatment and reassurance for a mobile, asymptomatic, incidentally found retroverted uterus, since most behave as a normal anatomical variant.
Step 4: Final Answer.
Following this papers answer key, pessary treatment is the marked answer, though modern teaching often favors no treatment for this exact scenario.
