However, Troi did not experience anything prior to the attack. What is not taken into account is the chaos and aftermath of an ambush attack, such as experienced by the away team in the scene. After such an unexpected event, chaos would have ensued and Lt. Worf would have been faced with the dual priorities of accounting for away team members, as well as assessing for and countering any possible threats (as can be seen by the away team posturing, once beamed aboard). In this case, Troi would have sensed the injuries and chaos that the team was experiencing many moments before they could contact the ship and request evacuation. In no way is this clairvoyance.
