Question

A 7 weeks pregnant lady has 1 accidental exposure to x-ray. Which of the following should be done ?

• A. Continue pregnancy
• B. Terminate pregnancy
• C. Chromosome analysis
• D. Pre invasive diagnostic testing

Answer 1

The Correct Option is A

When a pregnant woman at 7 weeks gestation has accidental exposure to x-rays, it is important to evaluate the potential risks to the developing fetus. X-rays are a form of ionizing radiation that can pose risks during pregnancy, especially in the early stages when organogenesis is occurring.

However, the level of risk depends on the dose and type of x-ray exposure. In most accidental exposures, the dose is typically low and unlikely to cause significant harm to the fetus. The threshold dose for teratogenic effects is higher than what is typically encountered in diagnostic radiology.

Given the information, the correct action is to:

• Continue pregnancy: Current guidelines suggest that the risks of teratogenic effects from a single diagnostic x-ray procedure are minimal. Therefore, there is no need for termination of pregnancy based solely on one accidental exposure.

The other options are generally not necessary immediately after a single low-dose exposure:

• Terminate pregnancy: Not indicated based solely on accidental x-ray exposure without significant evidence of high-dose exposure.
• Chromosome analysis: Not warranted as chromosomal changes due to low-dose radiation are unlikely.
• Pre invasive diagnostic testing: Invasive procedures, such as amniocentesis, are not recommended unless there are additional clinical indications.

As a guideline, healthcare professionals should assess the situation, provide counseling, and maintain regular prenatal care to monitor the pregnancy's progression.
