Choice A rationale:

This statement is accurate and provides essential information to the client.

Lifestyle modifications, including regular exercise and a balanced diet, are cornerstone strategies for managing PCOS.

Exercise can improve insulin sensitivity, reduce androgen levels, and support weight management.

A balanced diet can help regulate blood sugar levels and aid in weight management, which is crucial for many clients with PCOS.

Choice B rationale:

This statement is incorrect and misleading.

Weight gain and difficulty losing weight are often associated with PCOS due to insulin resistance and hormonal imbalances.

Suggesting that no dietary changes are needed can be detrimental to the client's health.

Choice C rationale:

Advising the client to avoid all carbohydrates is not appropriate.

While it's essential to manage carbohydrate intake, completely avoiding all carbohydrates is neither practical nor necessary.

The focus should be on choosing complex carbohydrates with a low glycemic index and maintaining a balanced diet.

Choice D rationale:

PCOS management typically includes a combination of lifestyle modifications and, in some cases, medication.

Suggesting that exercise and diet changes are unnecessary oversimplifies the treatment approach and may not adequately address the client's needs.

It's crucial to emphasize the importance of a holistic approach to PCOS management.
