Please help with this question, more than one answer may be correct: This figure show the relationship between cocaine dose and mean arterial blood pressure (left pane) and heart rate (right panel) in the squirrel monkey. Values shown (y-axis) are percent change in the parameter from a baseline measurement. Brackets show the range of parameter change after a control injection. Which of the following are true give the data in this graph? These squirrels obviously went on a rampage. (hint: don't pick this one) At 3.0 mg/kg of cocaine, increase in heart rate can not completely account for the increase in mean arterial blood pressure. At 0.03, 0.1, and 0.3 mg/kg doses of cocaine, either heart stroke volume or total peripheral resistance (or both) must be lower than at baseline. At 0.03, 0.1, and 0.3 mg/kg doses of cocaine, heart stroke volume and total peripheral resistance must both be higher than at baseline. At 3.0 mg/kg of cocaine, increase in heart rate could completely account for the increase in mean arterial blood pressure.

At 3.0 mg/kg of cocaine, increase in heart rate can not completely account for the increase in mean arterial blood pressure.


At 0.03, 0.1, and 0.3 mg/kg doses of cocaine, either heart stroke volume or total peripheral resistance (or both) must be lower than at baseline.
