Question

The nurse is preparing to administer an infusion of Pentam (pentamidine) to a client with PCP pneumonia. Which lab finding indicates an adverse reaction to the medication? A. \(\mathrm{RBC} 2,500,000 / \mathrm{cu}\). \(\mathrm{mm}\) B. WBC \(7500 /\) cu. mm C. Platelets 200,000/cu. mm D. Neutrophils \(52 \%\)

Short answer

Answer: RBC 2,500,000/cu.mm

Step-by-step solution

Option A: RBC 2,500,000/cu.mm

The normal range for red blood cells (RBC) is around 4,000,000 to 6,000,000/cu.mm. In this case, the RBC count is 2,500,000/cu.mm, which is lower than the normal range. A decrease in RBC count might indicate an adverse reaction to the medication.

Option B: WBC 7500/cu.mm

The normal range for white blood cells (WBC) is around 4,500 to 11,000/cu.mm. In this case, the WBC count is 7,500/cu.mm, which is within the normal range. Thus, this lab finding does not indicate an adverse reaction to the medication.

Option C: Platelets 200,000/cu.mm

The normal range for platelets is around 150,000 to 450,000/cu.mm. In this case, the platelet count is 200,000/cu.mm, which is within the normal range. This lab finding does not indicate an adverse reaction to the medication.

Option D: Neutrophils 52%

The normal range for neutrophils is around 45% to 70%. In this case, the percentage of neutrophils is 52%, which is within the normal range. This lab finding does not indicate an adverse reaction to the medication.

Conclusion

Among the given options, Option A (RBC 2,500,000/cu.mm) indicates an adverse reaction to the medication Pentam (pentamidine) as it is lower than the normal range for red blood cells.
