A patient is receiving low molecular weight heparin to prevent thromboembolic complications. The nursing student asks the nursing instructor the reason why this treatment is given instead of heparin

Question

What is the instructor's best explanation of the rationale for LMWH over heparin? A) "LMWH is associated with less thrombocytopenia than standard heparin."
B) "LMWH is associated with stronger anticoagulant effects than standard heparin."
C) "LMWH is given to patients who have a history of blood dyscrasia."
D) "LMWH is more effective than standard heparin for patients with hypertension."

Answer 1

A
Feedback:
Low molecular weight heparins are associated with less thrombocytopenia than standard heparin. Low molecular weight heparin is not stronger than standard heparin. Low molecular weight heparin is administered cautiously in patients with blood dyscrasia and hypertension.
