For a client admitted with a platelet count of 132,000 mm3, which intervention is most important?

Monitoring stools for occult blood is crucial for a client with a platelet count of 132,000 mm³ because this level indicates mild thrombocytopenia, which can increase the risk of bleeding. Individuals with lower platelet counts are more susceptible to bleeding, particularly gastrointestinal bleeding, which can be subtle and not readily apparent. By checking for occult blood in the stools, healthcare providers can identify potential internal bleeding early, allowing for timely intervention to manage the patient's condition.

The other options, while relevant to patient care, do not directly address the immediate risks associated with low platelet counts. Monitoring for signs of infection is important, as patients with lower platelet levels may have comorbid conditions or treatments that predispose them to infections, but the primary concern is bleeding. Encouraging regular dietary intake and increasing fluid intake are general health measures that support overall well-being but are not as critical in the context of monitoring for potential bleeding related to thrombocytopenia.
