What care should be taken regarding pregnant or breastfeeding patients when administering Tc-99m?

• A. Ensure patients have recovered from prior treatments
• B. Consider alternative imaging options due to potential risks
• C. Notify patients of the benefits and risks of imaging
• D. Provide hydration to minimize side effects

Answer: (B)

Considering the administration of Tc-99m to pregnant or breastfeeding patients involves careful consideration of potential risks associated with radiation exposure. Pregnant patients are at a greater risk because the developing fetus is more susceptible to the effects of ionizing radiation, which can potentially lead to developmental abnormalities or increased cancer risk later in life. Breastfeeding mothers also require caution because Tc-99m may be excreted in breast milk, which could then expose the nursing infant to radiation.

Alternative imaging options are often preferred, as they may provide necessary diagnostic information without the associated risks of radiation. For instance, non-radiation alternatives such as ultrasound or MRI could be more appropriate depending on the clinical scenario.

The importance of considering these alternative imaging options lies in prioritizing the safety of both the mother and the child, ensuring that any procedure performed does not pose unnecessary risks. This approach reflects a commitment to patient safety and responsibility in medical imaging practices.
