The nurse is reviewing the differential on a client who had a complete blood count and notes the neutrophils are within normal ranges if they are:
1500-8000
0-100
1000-4800
6-500
The Correct Answer is A
A. 1500-8000: Normal absolute neutrophil count (ANC) is 1,500 to 8,000 cells/mm³. This range indicates a normal immune response.
B. 0-100: Extremely low and indicative of severe neutropenia.
C. 1000-4800: Lower end of normal but does not cover the full normal range.
D. 6-500: Much lower than normal, indicating severe neutropenia.

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.
Correct Answer is B
Explanation
B. Liver: Grapefruit juice inhibits CYP3A4 enzymes in the liver, which metabolize many drugs (e.g., statins, calcium channel blockers). This inhibition can lead to increased drug levels and toxicity.
A. Gall bladder – The gall bladder stores bile but does not metabolize drugs.
C. Kidney – The kidneys excrete drugs, but grapefruit juice does not significantly impact renal metabolism.
D. Small bowel – Some drug metabolism occurs in the intestines, but grapefruit juice primarily affects liver enzymes.
