Practice Question
To prevent deep vein thromboses following knee replacement surgery, an adult male client is receiving daily subcutaneous enoxaparin. 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/mm² (150 to 400 × 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)]
Answer Choices:
Correct Answer:
Platelet count of 100,000/mm³ (100 x 10^9/L).
Rationale:
💫 Enoxaparin, a low molecular weight heparin, can cause heparin-induced thrombocytopenia (HIT), which is a serious adverse effect.
💫 A platelet count of 100,000/mm³ is below the normal reference range and suggests a potential complication.
💫 The nurse must report this finding immediately to prevent bleeding risks or thrombotic complications.
💫 The other labs are within normal limits and don’t indicate urgent concern.
