A nurse is reviewing a patient's laboratory values. Which of the following values should the nurse report to the provider?
Hct 45%
Hgb 14.7 g/dL
WBC 1,700/mm3
Platelets 160,000/mm3
The Correct Answer is C
A. Hct 45%. – Normal range for hematocrit (Hct) is 38-50%. No need to report.
B. Hgb 14.7 g/dL. – Normal range for hemoglobin (Hgb) is 13-17 g/dL. No need to report.
C. WBC 1,700/mm³. – Correct Answer. Normal WBC count is 4,000-11,000/mm³. A WBC count of 1,700/mm³ (neutropenia) places the patient at high risk for infection, requiring immediate intervention.
D. Platelets 160,000/mm³. – Normal range for platelets is 150,000-450,000/mm³. No need to report.

C. Respirations easy and unlabored, eats 50-75% of meals, vital signs stable – Respiratory status is not the primary concern in HHS.
D. Equal intake and output, denies pain or shortness of breath – These signs do not specifically indicate resolution of HHS.
Correct Answer is B
Explanation
A. Infuse the transfusion at a rate of 200 mL/hr. – Incorrect. The initial infusion should be slow (e.g., 75-100 mL/hr) to monitor for reactions.
B. Check the patient's vital signs every hour during the transfusion. – Correct Answer. Frequent monitoring is necessary to detect adverse reactions, such as fever or hypotension.
C. Leave the patient 5 minutes after beginning the transfusion. – Incorrect. The nurse should remain with the patient for the first 15 minutes, as most transfusion reactions occur early.
D. Flush the blood tubing with dextrose 5% in water. – Incorrect. Only normal saline should be used to flush blood tubing, as dextrose can cause hemolysis.
