Answer to Question 1

C
Pulsatile high-pressure lavage is often the irrigation of choice for necrotic wounds. The amount of irrigant is wound size dependent. Pressure settings on the device need to remain between 4 and 15 psi. Do not use this type of irrigation with graft sites or exposed blood vessels, muscle, tendon, or bone.

Answer to Question 2

C
Cryoprecipitate replaces factors VIII and XIII, von Willebrand's factor, and fibrinogen. It also replaces red cell mass and plasma volume and is expected to raise hemoglobin by 1 g/100 mL and hematocrit by 3 in a nonhemorrhaging adult. Using cryoprecipitate is the preferred method of replacing red blood cell mass.
