What action by a student nurse caring for a mother struggling with breastfeeding would require intervention from the supervising nurse?

The action that would require intervention from the supervising nurse is showing the mother how to hand express breast milk. While hand expression is a valuable skill for mothers to learn, if performed by a student nurse, it may exceed the scope of their training and experience, particularly if they are not fully competent in demonstrating the technique.

Teaching a mother a potentially complex skill like hand expression should be done by a trained healthcare professional who is confident in their approach and can ensure that the mother understands the technique thoroughly. This can also prevent any possible misinformation that could lead to difficulties in breastfeeding. Consequently, an experienced nurse should ideally lead this educational component to ensure proper technique and support for the mother.

On the other hand, assessing the baby's position and sucking behavior, demonstrating the use of an electric breast pump, and providing supplemental formula feedings are actions that can be undertaken by a student nurse under proper guidance and with adequate skills. These actions are commonly included in nursing education, allowing the student to support breastfeeding efforts effectively and address any immediate concerns the mother may have.
