Correct Answer is D
Explanation
A. Glucose of 6.7 mg/dL: Critically low; however, this is an unrealistic value because normal fasting glucose is 70-100 mg/dL. This might be a typo—if it were 6.7 mmol/L, it would be within the normal range.
B. WBC of 7000/mm³: Normal range (4,000-11,000/mm³), so no immediate concern.
C. Platelet count of 160,000/mm³: Normal range (150,000-400,000/mm³), so no immediate concern.
D. Hemoglobin of 6.2 g/dL: Normal hemoglobin levels are 13.5-17.5 g/dL (males) and 12-15.5 g/dL (females). A hemoglobin of 6.2 g/dL is critically low, indicating severe anemia, blood loss, or bone marrow suppression, which may require blood transfusion or further investigation.
Correct Answer is D
Explanation
A. Below 1.0: Too low, indicating inadequate anticoagulation, increasing the risk of clot formation.
B. 1.0-2.0: Subtherapeutic, meaning the medication is not effectively preventing clot formation.
C. Above 3.0: Too high, increasing the risk of bleeding complications
D. 2.0-3.0: The normal INR (International Normalized Ratio) for a client not on anticoagulants is 0.8-1.2. For clients on warfarin or other blood thinners, the target therapeutic range is typically 2.0-3.0, which reduces the risk of blood clots while minimizing the risk of bleeding. Some conditions, such as mechanical heart valves, may require a higher target range (2.5-3.5).
