A client has an absolute neutrophil count (ANC) of 500/mm³ (0.5 x 10⁹/L) after completing chemotherapy. Which intervention is most important for the nurse to implement?
Reference Range:
Neutrophils (ANC) [2500 to 5800/mm³ (2.5 to 5.8 x 10⁹/L)]
A.
Review need for pneumococcal vaccine.
B.
Implement bleeding precautions.
C.
Assess vital signs every 4 hours.
D.
Place the client in protective isolation.
The Correct Answer and Explanation is:
The correct answer is D. Place the client in protective isolation.
Explanation:
An absolute neutrophil count (ANC) of 500/mm³ (0.5 x 10⁹/L) is critically low and places the client at high risk for infection, a condition known as neutropenia. Neutrophils are white blood cells that play a key role in fighting infections. A normal ANC range is 2500-5800/mm³ (2.5-5.8 x 10⁹/L). When the ANC falls below 1000/mm³, the risk for infection increases significantly, and when the ANC is less than 500/mm³, the client is considered severely neutropenic, making them highly susceptible to infections from both external and internal sources, including the normal bacteria found in the body.
In this case, protective isolation is essential to reduce the client’s exposure to potential pathogens. Protective isolation measures include placing the client in a private room, ensuring that all healthcare personnel and visitors follow strict hand hygiene and wear protective gowns, masks, and gloves. Any potential sources of infection, such as flowers, fresh fruits, and visitors with infectious symptoms, should be avoided. These precautions are vital to prevent opportunistic infections, which can be life-threatening in neutropenic patients.
Option A, reviewing the need for a pneumococcal vaccine, is not an immediate priority because vaccines are typically given when the immune system is stable, and this client’s immune system is compromised.
Option B, implementing bleeding precautions, is more appropriate for clients with thrombocytopenia (low platelet count) rather than neutropenia.
Option C, assessing vital signs every 4 hours, is important for monitoring for signs of infection or sepsis, but it is secondary to implementing protective isolation to prevent infections in the first place.
The most crucial intervention is to protect the client from infections, making protective isolation the top priority in this scenario.
