A nurse is teaching a client who has septic shock about the development of disseminated intravascular coagulation (DIC). Which of the following statements should the nurse make?
Correct answer
C
Rationale
Correct Answer: C - DIC is caused by abnormal coagulation involving fibrinogen.
Rationale:
1. DIC is characterized by abnormal activation of the clotting cascade, leading to widespread microthrombi formation.
2. Fibrinogen is a key component in the clotting process and is consumed in excess during DIC, resulting in low levels.
3. Elevated platelet counts are not characteristic of DIC; instead, platelets are consumed, leading to thrombocytopenia.
4. Heparin may be used in acute cases of DIC, but it is not a lifelong treatment; the underlying cause must be addressed.
5. DIC is not a genetic disorder but a secondary complication of conditions like sepsis or trauma; it is not related to vitamin K deficiency.
Summary:
- Elevated platelet count (A) is incorrect as thrombocytopenia is seen in DIC.
- Lifelong heparin usage (B) is incorrect; it is not a
