The nurse is assigned to the care of a client in the ICU who is in cardiogenic shock. What priority nursing intervention is necessary to conserve myocardial energy and decrease workload of the heart?

A. White blood cell count "WBC" is used in the scoring system for DIC: WBC is not part of the DIC scoring system. The diagnosis relies on platelet count, fibrin degradation products, PT, aPTT, and fibrinogen levels. WBC may be elevated due to infection but does not directly indicate DIC.

B. DIC cases are triggered by other events such as infections: DIC is a secondary disorder that occurs in response to conditions like sepsis, trauma, malignancy, or obstetric complications. It results from widespread activation of coagulation and subsequent consumption of clotting factors.

C. DIC is a disease caused by a gene mutation: DIC is not a hereditary or genetic disease. It is an acquired condition resulting from a pathological event that triggers systemic coagulation. Genetic mutations are not implicated in its development.

D. Heparin is considered the gold standard for all clients with DIC: Heparin is not universally used in DIC and is reserved for specific cases such as chronic or thrombotic DIC. The mainstay of treatment is addressing the underlying cause and providing supportive care, including transfusions of platelets or clotting factors as needed.

A. Loss of distal pulses: Loss of pulses indicates vascular compromise from circumferential edema and rigid eschar, which can rapidly progress to ischemia. This finding signals the need for immediate escharotomy to relieve pressure and restore perfusion to the affected extremity.

B. Increased capillary ref: Prolonged capillary refill can suggest reduced circulation, but it appears earlier and is less definitive than the complete loss of palpable pulses. While concerning, it does not carry the same urgency or confirm the need for surgical decompression.

C. Increased sensitivity to pain in the area: Heightened pain sensitivity may occur as tissues swell, but pain alone does not indicate critical circulatory obstruction. The presence or absence of pain is not a reliable determinant for the need for escharotomy compared with pulse changes.

D. Limited range of motion: Decreased mobility is common with circumferential burns due to stiffness and swelling, but it does not reliably signal vascular compromise. Although it affects function, it is not an indication for emergent escharotomy in the absence of circulatory impairment.
