Choice A rationale:

 Applying corticosteroid cream generously can be a pharmacological measure to manage itching in Eczema, but it is not a non-pharmacological measure.

Corticosteroid creams contain medication and should be used as directed by a healthcare provider.

They are not considered non-pharmacological measures.

Choice B rationale:

 Taking antihistamine medication regularly is a pharmacological measure to manage itching in Eczema.

While antihistamines can help relieve itching, they are not considered non-pharmacological measures.

They require a prescription or recommendation from a healthcare provider.

Choice C rationale:

 Using cool compresses on the itchy areas is a non-pharmacological measure to manage itching in Eczema.

Cool compresses can provide relief from itching and help soothe the skin without the need for medication.

This is a suitable recommendation for managing itching in Eczema.

Choice D rationale:

 Suggesting that scratching the affected areas is an effective way to relieve itching is incorrect.

Scratching can worsen Eczema symptoms by damaging the skin's barrier, leading to more itching and potential infection.

It is essential to discourage scratching as a method of relieving itching in Eczema.
