Hematology

Question 1

Lab findings most indicative of DIC

Answer 1

Fibrin Degrading products(FDPs) and D dimer(form of FDP)

Question 2

Electrolyte abnormalities associated with MTP

Answer 2

Hypocalcemia, hyperkalemia

Question 3

Pancytopenia

Answer 3

Decreased levels of all blood cells
Increased risk of infx

Question 4

Required for vitamin b12 absorption

Answer 4

Intrinsic factor

Question 5

Heparin action

Answer 5

Reduce circulating thrombin
NOT a fibrinolytic
Does decrease Plt but not the main purpose…too much decrease could indicate HIT

Question 6

Polycythemia

Answer 6

• Increased Hct/Hgb in blood
• Can cause cyanosis d/t increased blood viscosity causing sluggish blood flow
• or can be caused by cyanosis/hypoxia

Question 7

Effect of MTP on oxyhemoglobin curve

Answer 7

Shift to left d/t PRBCs being low in 2,3 DPG
This causes greater pickup at the lung but less drop off at tissue

Question 8

Considerations while doing MTP

Answer 8

Hyperkalemia, hypocalcemia, decreased 2,3 DPG, hypothermia, the last two which will make you more prone to hypoxia due to the increased affinity of oxygen

Question 9

Normal FDP level

Answer 9

<10
