Many websites containing medical information intended for medical professionals require that the user assert that he/she is one before the content can be accessed. Merck Connect is an example.
Does a curious user (not employed in the medical field) clicking on the "I am a health care professional" button to access the content risk liability of any kind? In particular, do the actions of merely clicking said button (whereby said user falsely asserts he/she is a health care professional) or accessing the content behind the button (which may be restricted by law or otherwise) attract liability? What relevant legislation exists, if any, regarding access to said websites?

Under French law, the following requirement exists, based on a December 2011 law on food safety effective May 2012 (see http://www.itena-clinical.com/en/):
les sections des sites internet réservées aux seuls professionnels de santé doivent être, a minima, accessibles après une page d'engagement de l'internaute, certifiant qu’il est un professionnel de santé.
Rough translation based on Google Translate output:
sections of websites reserved solely for healthcare professionals shall only be accessible after at least an agreement page certifying that the user is a healthcare professional.
Does a similar requirement exist under United States federal law?
