1. Which of the following parameters is monitored when using a left ventricular assist device (LVAD)? A. Right atrial pressure B. Left ventricular ejection fraction C. Pump flow rate D. Systemic vascular resistance Answer: C. Pump flow rate Rationale: Pump flow rate is monitored when using an LVAD to ensure adequate blood flow and support for the patient's circulation. 2. Which statement is true regarding the function of an intra-aortic balloon pump (IABP)? A. It provides long-term cardiac support B. It increases systemic vascular resistance C. It enhances myocardial oxygen supply D. It is used as a bridge to heart transplantation Answer: C. It enhances myocardial oxygen supply Rationale: An IABP works by inflating and deflating a balloon in the aorta to improve myocardial oxygen supply and decrease the workload of the heart. 3.
