A. Incorrect response: See explanation D
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: When attempting to wean a PMV patient from mechanical ventilation, if the delivery of a set minute ventilation is imperative, either volume, or pressure assist-control, or possibly pressure-regulated volume control modes may be beneficial. Because a mandatory minimum minute ventilation can be delivered within specific pressure limits, PRVC may be particularly useful if a lack of staffing restricts in-house after-hours coverage of PMV patients.?
