A client is admitted to the emergency department following a motor vehicle accident. The nurse is aware that the client is at increased risk for hemorrhage due to which factor?

A) Correct. Dizziness and lightheadedness are common signs of decreased blood flow, indicating a potential worsening of internal bleeding. Immediate intervention is required to prevent further complications.

B) Incorrect. While a slightly decreased blood pressure could be a concern, it may not be an immediate priority. The nurse should closely monitor the blood pressure and respond promptly if it drops significantly or trends downward.

C) Incorrect. Pale and cool skin may indicate poor perfusion, but it doesn't necessarily require immediate intervention unless it worsens or is accompanied by other alarming signs.

D) Incorrect. Although heart rate can be affected by hemorrhage, being within the normal range doesn't necessarily warrant immediate intervention. Other signs and symptoms should be considered as well.

A) Correct. In liver cirrhosis, the damaged liver may sequester platelets, leading to a decreased platelet count. However, an elevated platelet count (thrombocytosis) can occur as a compensatory response to decreased liver function and is a sign of an increased risk of hemorrhage due to poor clot formation.

B) Incorrect. Low prothrombin time (PT) indicates faster clotting and is not associated with an increased risk of hemorrhage.

C) Incorrect. Decreased ammonia levels are a positive finding in liver cirrhosis, as elevated ammonia levels are harmful to the brain.

D) Incorrect. Elevated liver enzymes are indicative of liver damage, but they do not directly impact the client's risk of hemorrhage.
