39) During of your clinical rotations, you are helping prepare a patient for mobility on the cardiac step-down unit. You place the telemetry leads but are not confident in your recall of the normal orientation. You place them as shown. Image description: Anterior view of a person’s chest with ECG leads placed. Black lead attaches to their left upper chest. White lead attaches to their right upper chest. Brown lead attaches just superior to the xiphoid process. Red lead attaches to the left lower chest. Green lead attaches to the right lower chest.

19.  In the following diagram, what activity in the cardiac cycle does number 3 indicate?

27. What is this patient’s ejection fraction?

21) In the following diagram, what activity in the cardiac cycle does number 5 indicate?  

31) Where in the excitatory-conduction pathway of the heart is there likely to be an abnormality given the findings of this ECG?

4) During a clinical rotation, you observe a who patient experiences chest pain with aerobic activity. They take their prescribed dose of nitroglycerin spray under the tongue. You recall the role of nitric oxide in control of tissue blood flow. What is the most likely reason they are taking this medication?

28) If you measure this person’s pulse to be 95 bpm, what is their resting cardiac output?

6) When a person exercises specific skeletal muscles, how do local arterioles and metarterioles acutely respond to decreased local oxygen levels?
