- C. A signed consent is not required
- D. Eating, drinking, and medications are allowed before this test

Patients may need to remove jewelry and metallic objects to prevent interference with the imaging.

If a patient's blood pressure is 150/96, what is his pulse pressure?
- A. 54
- B. 96

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.
