a) A patient who is on warfarin and actively bleeding, or requires immediate surgery
T/F: Fresh frozen plasma contains platlets.
False
T/F: Cryoprecipitate requires ABO matching before administration for all patients.
False
What blood product is typically used for patients having an acute sickle cell crisis?
Packed red blood cells
T/F: Disseminated intravascular coagulation (DIC) is a life-threatening combination of clotting at the microscopic level as well as free bleeding at the systemic level.
True
T/F: Your patient is in DIC. You would expect this patient’s platelet count to be low.
True
Treatment for DIC can vary between giving blood components or low-dose heparin. Which of the following statements is true regarding DIC treatment?
a) All patients in DIC should be given concurrent whole blood to replace lost blood.
b) Patients in DIC will all be given platelets and cryoprecipitate.
c) The decision to give either blood components or heparin depends on whether bleeding predominates, or fibrin deposits predominates.
d) Patients in DIC are rarely given heparin because heparin will accelerate free bleeding.
c) The decision to give either blood components or heparin depends on whether bleeding predominates, or fibrin deposits predominates.
What is the most common genetic bleeding disorder?
von Williebrand’s disease
Cardiac output usually increases by ___% during pregnancy and increases even higher during labor.
40
T/F: Hypotension develops more readily and more markedly following sympathetic blockage in pregnant patients due to vascular tone being more dependent on sympathetic control.
True
T/F: Maternal blood glucose is always relatively high (140 - 180 mg/dl) to supply glucose to the growing fetus
False
Preterm labor is defined as regular uterine contractions prior to week ____ that are sufficient frequency and intensity to effect effacement and dilation of the cervix.

Your patient is a 28-week gestation, who develops sudden painless, bright red bleeding that occurred without warning. What should you suspect?
Placenta previa
T/F: Your patient has placenta abruption. This patient would typically present with an increased hemoglobin and hematocrit as her body attempts to compensate for the hemorrhage.

c) PEEP can only be used in neonates after the initial resuscitation phase
d) PEEP can only be used in neonates as a last resort (i.e. cardiac arrest)
b) Initial lung recruitment may require initially high PEEP to expand the lungs
What is the typical range for respiratory rate of a neonate?
40 - 60 breaths per minute
T/F: Intubation in any 3rd trimester patient should always be considered a difficult airway because of the failure rate of intubation in these patients.

False, pregnant patients typically require a reduced amount of sedation and anesthesia
When doing fluid resuscitation of a patient in maternal shock, is it preferred to have massive crystalloid infusion or early blood transfusion?
