A client's lab report shows a platelet count of 47,000. The normal range for platelets is between 150,000 and 450,000. Which of the following nursing interventions is the nurse's highest priority?

A. 150 mL: This calculation is incorrect because the amount of fluid drained includes both the saline solution and the urine. The true urine output is the difference between what was drained and what was instilled.

B. 100 mL: The true urine output is calculated by subtracting the amount of saline instilled from the total output. In this case, 300 mL was drained, and 200 mL was saline. Therefore, 300 mL - 200 mL = 100 mL of true urine output.

C. 200 mL: This would be the amount of saline instilled, not the urine output. The true urine output needs to account for the saline volume that was used in the irrigation process.

D. 50 mL: The correct calculation subtracts the 200 mL of saline from the total 300 mL drained, which gives 100 mL of true urine output, not 50mL.

A. Physician order for life-sustaining treatment: Life-sustaining treatment is not part of the initial chemotherapy plan unless end-of-life decisions are involved. The focus is on managing side effects and preventing complications.

B. Encourage low residue foods: Low-residue foods are not a priority in the initial chemotherapy plan. The primary concern is managing immunosuppression and preventing infections, which makes neutropenic precautions more important.

C. Neutropenic precautions: Neutropenic precautions are crucial during induction chemotherapy to prevent infections due to the lowered white blood cell count. The nurse should educate the client on hygiene and infection prevention.

D. An advanced directive: While important, an advanced directive is not the immediate focus during chemotherapy. The initial plan centers on managing chemotherapy effects and preventing complications like infections.
