The assist-control mode of ventilation functions in which of the following manners?

a. It delivers gas at preset volume, at a set rate, and in response to the patient's inspiratory efforts.
b. It delivers gas at a preset volume, allowing the patient to breathe spontaneously at his or her own volume.
c. It applies positive pressure during both ventilator breaths and spontaneous breaths.
d. It delivers gas at preset rate and tidal volume regardless of the patient's inspiratory efforts.

Question 2

a. aspirin and Clopidogrel (Plavix).
b. aspirin and Abciximab (ReoPro)
c. aspirin and Eptifibatide (Integrilin)

Answer to Question 1

A
Whereas a breath that is initiated by the patient is known as a patient-triggered or patient-assisted breath, a breath that is initiated by the ventilator is known as a machine-triggered or machine-controlled breath. A time-triggered breath is a machine-controlled breath that is initiated by the ventilator after a preset length of time has elapsed. It is controlled by the rate setting on the ventilator (e.g., a rate of 10 breaths/min yields 1 breath every 6 seconds). Flow-triggered and pressure-triggered breaths are patient-assisted breaths that are initiated by decreased flow or pressure, respectively, within the breathing circuit.

Answer to Question 2

A
Because platelet activation is a complex process involving multiple pathways, combination therapy with two or more agents has proven most effective. The current standard of care for percutaneous coronary intervention typically includes dual antiplatelet therapy with aspirin and a thienopyridine. These oral agents are administered before the procedure and continued at discharge. Abciximab, eptifibatide, and tirofiban are all intravenous antiplatelet agents.
