The nurse is administering SUBQ enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse?
Reference Range:
Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)]
Platelets [150,000 to 400,000/mm3 (150 to 400 x 10^9/L)]
Creatinine [0.5 to 1.1 mg/dL (44 to 97 μmol/L)]
Blood Urea Nitrogen (BUN) [10 to 20 mg/dL (3.6 to 7.1 mmol/L)]
Platelet count of 100,000/mm3 (100 x 10^9/L).
Serum creatinine 1.0 mg/dL (88.4 μmol/L).
Blood urea nitrogen (BUN) 20 mg/dL (7.1 mmol/L).
Hematocrit 45% (0.45 volume fraction).
The Correct Answer is A
A. A platelet count of 100,000/mm3 indicates thrombocytopenia, which increases the risk of bleeding with enoxaparin and requires immediate action.
B. A serum creatinine level of 1.0 mg/dL is within the normal range and does not require immediate action.
C. A BUN level of 20 mg/dL is at the upper end of the normal range but does not typically require immediate action unless accompanied by other symptoms.
D. A hematocrit level of 45% is within the normal range and does not require immediate action.
