The nurse is caring for a client diagnosed with disseminated intravascular coagulation (DIC). When completing an assessment for decreased perfusion from clotting, the nurse would observe for which manifestation?
Cyanosis
Petechiae
Epistaxis
Hematuria
The Correct Answer is A
A. Cyanosis, or a bluish discoloration of the skin, occurs when there is insufficient oxygen in the blood, which can result from decreased perfusion due to clotting in DIC. It is a sign of poor oxygenation and perfusion.
B. While petechiae (small red or purple spots) are a common manifestation of DIC due to microvascular clotting and bleeding, they are not a sign of decreased perfusion.
C. Epistaxis (nosebleeds) is another bleeding manifestation of DIC but is not indicative of decreased perfusion, which is more closely related to cyanosis.
D. Hematuria (blood in the urine) can occur in DIC due to clotting in the kidneys or urinary tract. However, it is more related to bleeding than to decreased perfusion.

Correct Answer is C
Explanation
A. Hypermagnesemia can cause bradycardia and hypotension, but it is less commonly associated with PVCs. This does not align with the lab results provided.
B. Hypocalcemia can cause arrhythmias, but it is not the most likely cause of PVCs in this case, considering other findings.
C. Hypokalemia (low potassium) is a known cause of PVCs. The patient's potassium level is 2.8 mEq/L, which is significantly low and most likely contributing to the PVCs.
D. Although hyperglycemia can affect cardiac function, it is less commonly linked to PVCs compared to electrolyte imbalances, such as hypokalemia.
