Twelve hours following orthopedic surgery on the right leg, the client begins to have acute chest pain and difficulty breathing. Which action should the nurse take first?

Notify healthcare provider (HCP) of the symptoms and administer a PRN pain medication.

Increase the client's IV flow rate and start low flow oxygen.

Position the client on the left side while immobilizing the affected leg.

Take the client's vital signs and auscultate all lung sounds.

Answer and Explanation

The Correct Answer is B

A. Notify healthcare provider (HCP) of the symptoms and administer a PRN pain medication. While notifying the HCP is necessary, administering pain medication does not address the underlying cause of the client’s acute chest pain and difficulty breathing. These symptoms suggest a possible pulmonary embolism (PE), a life-threatening complication after orthopedic surgery. Immediate supportive interventions should be initiated before notifying the provider.
B. Increase the client's IV flow rate and start low-flow oxygen. The client is experiencing acute respiratory distress, which could indicate a pulmonary embolism (PE), a fat embolism, or another postoperative complication. Providing oxygen helps improve oxygenation and reduce hypoxia, while increasing the IV flow rate helps maintain perfusion and prevent shock. These immediate interventions support vital functions while preparing for further medical management.
C. Position the client on the left side while immobilizing the affected leg. This position is used in air embolism management, not pulmonary embolism. In suspected PE, the priority is to optimize oxygenation and circulation rather than repositioning. The affected leg should be immobilized to prevent further embolization, but this is not the first priority.
D. Take the client's vital signs and auscultate all lung sounds. While assessing the client’s vital signs and lung sounds is important, intervention should not be delayed. The priority is to support oxygenation and circulation immediately, as PE can rapidly lead to hypoxia, hemodynamic instability, or cardiac arrest. Assessment should be done concurrently with emergency interventions.

Correct Answer is A

Explanation

A. Insert a large bore peripheral IV catheter. The client is showing signs of shock (tachycardia, hypotension, tachypnea) likely due to envenomation and systemic venom effects. Rapid IV access is essential for fluid resuscitation, administration of antivenom, and management of shock. A large bore (18-gauge or larger) IV catheter allows for aggressive fluid therapy to maintain perfusion and prevent circulatory collapse.
B. Raise extremity above the heart. Elevating the limb can increase venom circulation, worsening systemic effects. Instead, the affected extremity should be kept at heart level to slow venom spread while ensuring adequate perfusion.
C. Tighten the cloth around the leg. Further tightening the makeshift tourniquet can lead to vascular compromise, ischemia, and increased local tissue damage. Modern guidelines discourage tourniquets as they do not prevent venom spread effectively and may worsen outcomes. The best approach is to loosen or remove restrictive bindings and keep the limb immobilized at heart level.
D. Apply ice over the bite mark. Cold therapy is contraindicated as it can worsen tissue damage by causing vasoconstriction, trapping venom, and increasing necrosis. Instead, the priority is IV access, fluid resuscitation, and preparing for possible antivenom administration.

A. Give the client 15 g of carbohydrates and retest the blood glucose in 15 minutes B. Bolus the client with 1 L of 3% sodium chloride solution C. Hold the insulin infusion D. Decrease the sodium concentration in the IV fluids from 0.9% to 0.45% E. Alert the provider of the current blood glucose level. F. Add 20 mEq of potassium chloride to the IV fluids. G. Start a regular diet

Correct Answer is ["D","E","F"]

Explanation

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.
