Which symptoms should a nurse be careful to observe for when assessing a patient with thrombocytopenia?

A. Enlarged thyroid and excitability: These are signs of hyperthyroidism, not a platelet disorder. B. Discoloration of the nails and sclera: Scleral discoloration (yellow) indicates jaundice/liver issues, not low platelets. C. Petechiae on the skin and bleeding gums: Thrombocytopenia is a low platelet count. Platelets are necessary for primary hemostasis; without them, patients develop small capillary bleeds (petechiae) and mucosal bleeding (gums, nose). D. Distended neck veins and skin discoloration: More consistent with heart failure or circulatory overload, not thrombocytopenia.
