NSG 210 Test 3 Study Guide: Clotting and
Mobility (without medications) Exam
Questions With Verified Answers.
Clots - answer✔✔made up of platelets, RBC, and fibrin
-formation mediated by 30 proteins (clotting factors) - made by liver
intrinsic pathway - answer✔✔less protective and more reactive; internal problem
-impaired blood flow, excessive substances that promote clotting
extrinsic pathway - answer✔✔outside the bloodstream
-happens with trauma
what is a nursing consideration for those at risk for bleeding? - answer✔✔2 IVs at least 20 G
temporary platelet seal - answer✔✔platelets are activated when injury exposes collagen and
VonWillebrand factor to the blood
-these 2 factors draw platelets to injury site --> platelets activated
-releasing prothrombotic molecules which cause platelet aggregation --> clot grows rapidly
-activated platelets trigger the cascade and form thrombin and fibrin
tissue factor - answer✔✔exposed with injury to vessels and also triggers the coagulation cascade
-leading to fibrin and clot formation
coagulation panel - answer✔✔-prothrombin time (PT)
-international normalized ratio (INR)
-platelets
-activated partial prothrombin time (aPTT)
-D-Dimer
-H/H
international normalized ration (INR) - answer✔✔ratio of clotting time
-0.8 - 1.5 is normal
-2.5 - 3.5 is the therapeutic level (someone on anticoagulants)
- >3 means blood is not clotting fast enough (stop/decrease anticoagulants)
-increase heparin to increase levels
platelets - answer✔✔come from bone marrow
-clump together at bleeding site to form a clot
-150,000 - 400,000
- <25,000 is critical - primary hemostasis
-activated by *collagen*
activated partial prothrombin time (aPTT) - answer✔✔time it takes for blood to clot
-20 - 40 seconds
-increase for someone on anticoagulants
-used to monitor effect of heparin
D-Dimer - answer✔✔<0.5
-high level means could be a clot
-pregnancy can cause increased levels
Hgb - answer✔✔12-15
Hct - answer✔✔35-45
clotting cascade - answer✔✔I - fibrin
II - thrombin
III - tissue factor: comes from injured endothelial cells
clotting assessment - answer✔✔-age and sex
-description of bleeding episode (epistaxis, menorrhagia, or hematomas)
deep vein thrombophlebitis signs and symptoms - answer✔✔-cramping calf pain (may be
painless)
-edema
-tenderness to the touch
superficial vein thrombophlebitis signs and symptoms - answer✔✔-redness along the vein
-warmth and tenderness along the vein
DVT at risk - answer✔✔-sedentary
-obese
-post-op
