A product owner presented the backlog and the team raised concerns about implementing some features due to impediments. What should the project manager advise the product owner to do next?

The project manager should advise the product owner to ensure impediments are captured and prioritized based on the highest-valued features because addressing impediments that block high-value work maximizes the delivery of value. This aligns with agile principles, where the product owner is responsible for maximizing product value. Estimating financial impact and requesting funding might be necessary later but isn't the immediate next step for the product owner. Removing the easiest impediments first might not address the most critical blockers to value delivery. Notifying management is a good step, but the product owner's immediate action should be to understand the impact on value and prioritize accordingly before escalating.
