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 A
Explanation
A. Intravenous: IV administration delivers medication directly into the bloodstream, allowing for the fastest onset of action (within seconds to minutes).
B. Topical patch: Slow absorption, designed for long-term, sustained release.
C. Sublingual: Faster than oral, but slower than IV (absorbed through mucous membranes).
D. Intramuscular: Faster than oral, but slower than IV, as the drug must diffuse into the bloodstream from muscle tissue.
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).
