The nurse assesses a client with petechiae and ecchymosis scattered across the arms and legs. Which laboratory result should the nurse review?

A. Hemoglobin levels primarily indicate the oxygen-carrying capacity of the blood and are not typically affected in conditions associated with petechiae and ecchymosis.B. White blood cell count may be elevated in response to infection but is not directly related to the presence of petechiae and ecchymosis.C. Red blood cell count primarily reflects the oxygen-carrying capacity of the blood and is not typically affected in conditions associated with petechiae and ecchymosis.D. Platelet count is crucial in assessing for thrombocytopenia, a condition characterized by low platelet levels, which can lead to increased bleeding and bruising, including petechiae and ecchymosis.
