The nurse receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)

Choice A reason: Neutropenic precautions are necessary when the WBC count is critically low, typically below the normal range. Since the client’s WBC count is now within the normal range, these precautions are no longer required.

Choice B reason: Filgrastim is designed to increase white blood cell (WBC) production in individuals with neutropenia. In this case, the client’s WBC count has increased from 2,500/mm³ (2.5 x 10⁹/L) to 5,000/mm³ (5 x 10⁹/L), reaching the lower limit of the normal reference range (5,000 to 10,000/mm³ or 5 to 10 x 10⁹/L). This indicates that the medication has achieved its desired effect, and it is appropriate to inform the client of this positive outcome.

Choice C reason:reason: Reviewing culture and sensitivity reports would be relevant if there was evidence of infection or a need to evaluate ongoing treatment for an infection. This is not indicated by the scenario provided.

Choice D reason: While assessing vital signs is generally important, there is no indication in this scenario that an acute issue requiring immediate vital sign monitoring is present.

Choice C reason: Sodium polystyrene sulfonate is a cation-exchange resin that binds to potassium in the intestine and removes it from the body through the stool. Sodium polystyrene sulfonate is used to treat hyperkalemia, or high potassium level, which can be caused by AKI, certain medications, or other conditions. Hyperkalemia can cause cardiac arrhythmias, muscle weakness, paralysis, or death. The normal range of potassium for adults is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). Therefore, a decrease in potassium from above normal to within normal indicates that sodium polystyrene sulfonate has been effective in lowering potassium level and preventing complications. The nurse should monitor the client's serum potassium level regularly and adjust the dose of sodium polystyrene sulfonate as needed.

Choice A reason: Hemoglobin level of 13.5 g/dL (135 g/L) is not a laboratory finding that indicates that the medication has been effective, but rather a normal value that reflects the amount of oxygen-carrying protein in the blood. Hemoglobin is not affected by sodium polystyrene sulfonate or potassium level. The normal range of hemoglobin for adults is 12 to 16 g/dL (120 to 160 g/L). Therefore, a hemoglobin level of 13.5 g/dL does not indicate any change or improvement in the client's condition.

Choice B reason: Serum glucose level of 120 mg/dL (6.7 mmol/L) is not a laboratory finding that indicates that the medication has been effective, but rather a slightly elevated value that reflects the amount of sugar in the blood. Glucose is not affected by sodium polystyrene sulfonate or potassium level. The normal range of glucose for adults is 74 to 106 mg/dL (4.1 to 5.9 mmol/L). Therefore, a serum glucose level of 120 mg/dL may indicate impaired glucose metabolism or diabetes mellitus, but not the effectiveness of sodium polystyrene sulfonate.

Choice D reason: Serum ammonia level of 30 mg/dL (17.62 µmol/L) is not a laboratory finding that indicates that the medication has been effective, but rather a normal value that reflects the amount of nitrogen waste in the blood. Ammonia is not affected by sodium polystyrene sulfonate or potassium level. The normal range of ammonia for adults is 10 to 80 mg/dL (6 to 47 µmol/L). Therefore, a serum ammonia level of 30 mg/dL does not indicate any change or improvement in the client's condition.
