You are dispatched to a residence for an elderly female who has possibly suffered a stroke. She is semiconscious and has slow, irregular breathing. You should:

In the scenario presented, the elderly female is semiconscious and exhibiting slow, irregular breathing, which suggests there may be a compromised airway and the potential for aspiration due to her altered level of consciousness. Manually opening her airway and suctioning her oropharynx is crucial in this situation.

By manually opening the airway, you ensure that there is a clear path for air to enter the lungs, reducing the risk of airway obstruction often seen in patients with altered mental status. Additionally, suctioning the oropharynx helps to remove any secretions, blood, or vomit that could obstruct her airway and lead to further respiratory complications.

While administering oxygen is important, the priority must be to ensure that the airway is patent (open) and that any obstructive materials are cleared. Simply placing the patient in the recovery position might not adequately address the immediate need to secure the airway in a semiconscious state, where risk of airway blockage is higher. Checking for a pulse is less critical at this moment since the focus should be on stabilizing the airway first due to the respiratory irregularities observed.
