Question

a nurse caring for a client who has bone marrow suppression. the nurse should identify which of the following laboratory values as consistent with this diagnosis? select all that apply. a wbc 2,100 mm³ b iron 220 mc/dl c platelet count 75,000 mm³ d pt 30 seconds

Explanation:

• Option A: Normal WBC range is \(4,000 - 11,000\space mm^{3}\). A WBC of \(2,100\space mm^{3}\) (leukopenia) is consistent with bone - marrow suppression as the bone marrow fails to produce enough white blood cells.
• Option B: Normal iron range is \(50 - 170\space mc/dL\). An iron level of \(220\space mc/dL\) (elevated iron) is not a typical finding in bone - marrow suppression. Bone - marrow suppression mainly affects cell production (WBC, RBC, platelets) rather than directly causing such an elevated iron level.
• Option C: Normal platelet count is \(150,000 - 450,000\space mm^{3}\). A platelet count of \(75,000\space mm^{3}\) (thrombocytopenia) is consistent with bone - marrow suppression as the bone marrow is not producing enough platelets.
• Option D: Normal PT (prothrombin time) is \(11 - 13.5\) seconds. A PT of \(30\) seconds (prolonged PT) can occur due to decreased clotting factor production (which can be related to liver disease, vitamin K deficiency, or in some cases, if there is a severe reduction in clotting factor - producing cells due to bone - marrow suppression affecting the precursor cells for some clotting factors in a more complex hematological context).

Answer:

A. WBC \(2,100\space mm^{3}\), C. Platelet count \(75,000\space mm^{3}\), D. PT \(30\) seconds
