A nurse is reviewing the laboratory results of a group of clients. Which of the following laboratory findings should the nurse report to the provider?

Glucose of 6.7 mg/dl

WBC of 7000/mm3

Platelet count of 160,000/mm3

Hemoglobin of 6.2 g/dl

Answer and Explanation

The Correct Answer is D

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 B

Explanation

A. "This test shows if I am dehydrated." aPTT is not used to assess hydration status; it measures blood clotting ability.

B. "This test measures deficiencies in clotting factors." aPTT assesses the intrinsic clotting pathway and helps evaluate clotting factor deficiencies, especially in conditions like hemophilia or when a client is on heparin therapy.

C. "If my level is too low, I need to consume more sodium." Sodium intake does not directly impact aPTT values.

D. "The aPTT is used to measure my sugar levels." Glucose levels are measured by a blood sugar test, not an aPTT test.

A. BUN 11 mg/dl serum creatinine 0.8 mg/dl B. BUN 15 mg/dl serum creatine 1.0 mg/dl C. BUN 10 mg/dl, serum creatinine 0.6 mg/dL D. BUN 25 mg/dL serum creatinine 2.3 mg/dl

Correct Answer is D

Explanation

A. BUN 11 mg/dL, serum creatinine 0.8 mg/dL: These values are normal (BUN: 7-20 mg/dL, creatinine: 0.6-1.2 mg/dL), which are not expected in chronic kidney disease (CKD).

B. BUN 15 mg/dL, serum creatinine 1.0 mg/dL: Also within normal limits.

C. BUN 10 mg/dL, serum creatinine 0.6 mg/dL : These values suggest normal kidney function, not CKD.

D. BUN 25 mg/dL, serum creatinine 2.3 mg/dL : Both elevated BUN and creatinine indicate impaired kidney function, which is expected in CKD.
