Final answer:
Interventions for a patient exhibiting vagal response involve increasing heart rate and stroke volume by targeting parasympathetic and sympathetic stimulation.
Step-by-step explanation:
Interventions for a patient exhibiting vagal response involve targeting the parasympathetic stimulation while suppressing the response. This can be achieved by increasing heart rate and stroke volume. One way to increase heart rate is through sympathetic stimulation, which can be achieved through physical activity. Additionally, parasympathetic stimulation can be suppressed through medication such as atropine.
