Answer to Question 1

D
The normal range for platelets is 200,000 to 400,000/mm3 . Platelets are needed for blood clotting. This patient's platelet count is extremely low and he or she is at grave risk for severe bleeding. The low platelet count is an indication of an adverse reaction to heparin known as he-parin-induced thrombocytopenia (HIT). The heparin needs to be discontinued and the patient needs to receive platelet therapy before life-threatening hemorrhage occurs.

Answer to Question 2

B
1 is to 30 as X is to 20, so 1/30 = X/20; 20  1 = 20; 20 30 = 0.67 mL, rounded up to 0.7 mL.
