Express answer in correct units.

There are two conversions to perform. The default input units are centimeters (cm) for height and kilograms (kg) for weight, and meters squared (m 2 ). The following is a sample prescription and stepwise approach to calculate day s' supply. One arm: apply 3 fingertip units. Archives of Internal Medicine. PVR = pressure gradient/pulmonary blood flow. BSA is a measurement used in many medical tasks. 3 BSA is most often used when dosing chemotherapy drugs and can be calculated by the inches and pounds method or the metric formula that utilizes centimeters and kilograms. Weight/lbs. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health . b) A 220-lb, 6-ft 5-in. However, this can be automatically converted into other area units via the pull-down menu. The nurse administers how many drops per minute to infuse the blood as ordered?
