A client who is admitted to the emergency department (ED) following a motorcycle collision is having difficulty breathing. While assessing the client's chest and lungs, the nurse notes that there are no breath sounds over the left lung fields. Which action(s) should the nurse implement? Select all that apply.

A. Administer furosemide IV over ten minutes. While slow IV administration is recommended to prevent ototoxicity, the priority concern is that milrinone and furosemide are incompatible when administered in the same IV line. The nurse must first ensure separate IV access before considering the administration rate.
B. Notify the healthcare provider (HCP) of the incompatibility of the two drugs. The nurse does not need to notify the HCP but should instead use a separate IV line or flush the line thoroughly before and after administration if only one access is available. Milrinone and furosemide should never be mixed, as their combination can cause precipitation, leading to catheter occlusion or embolization.
C. Infuse furosemide through a central line to prevent extravasation. Furosemide can be given peripherally or centrally, but the concern here is drug incompatibility, not extravasation. Furosemide is not a vesicant, so central line administration is not required unless no peripheral access is available.
D. Give furosemide through a separate IV access. Milrinone is incompatible with furosemide due to pH differences, which can lead to precipitation and potential catheter occlusion. To ensure safe administration, furosemide should be given through a separate IV line or, if no secondary access is available, the line should be flushed thoroughly before and after administration.

A. Give the client 15 g of carbohydrates and retest the blood glucose in 15 minutes.
A blood glucose of 250 mg/dL is still high but does not require immediate carbohydrate administration. Carbohydrates are given in cases of hypoglycemia (blood glucose <70 mg/dL) or when transitioning from IV to subcutaneous insulin at lower glucose levels.
B. Bolus the client with 1 L of 3% sodium chloride solution.
The client’s sodium is already elevated (152 mEq/L), and hypertonic saline (3% NaCl) would worsen hypernatremia and increase the risk of neurological complications. Instead, hypotonic fluids (0.45% NaCl) are recommended once intravascular volume is stabilized.
C. Hold the insulin infusion.
HHS is managed with continuous insulin infusion to gradually reduce glucose levels. The blood glucose is still above the target range (250 mg/dL), so insulin should not be stopped prematurely to avoid a rebound in hyperglycemia.
D. Decrease the sodium concentration in the IV fluids from 0.9% to 0.45%.
Once circulatory volume is restored, fluids should be switched to 0.45% sodium chloride to correct hypernatremia and intracellular dehydration. This is a standard part of HHS treatment after initial fluid resuscitation.
E. Alert the provider of the current blood glucose level.
Glucose levels are improving but still high (250 mg/dL), requiring adjustments in fluid and insulin therapy. The provider should be informed to assess whether insulin titration or fluid changes are necessary.
F. Add 20 mEq of potassium chloride to the IV fluids.
Insulin therapy drives potassium into cells, leading to hypokalemia (K⁺ = 3.2 mEq/L), which can cause cardiac arrhythmias and muscle weakness. Potassium replacement is required to prevent complications and maintain normal levels.
G. Start a regular diet.
Clients with HHS require gradual rehydration and glucose control before transitioning to oral intake. A regular diet is not appropriate until the client is stable, glucose levels are consistently controlled, and IV therapy is discontinued.
