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 C

Explanation

A. pH 7.25 and HCO₃⁻ 18 mEq/L. A pH of 7.25 is still acidotic, and a bicarbonate level of 18 mEq/L is below the normal range (22–26 mEq/L), indicating persistent metabolic acidosis. This suggests that ketoacidosis is not fully resolved, requiring continued insulin therapy, hydration, and electrolyte management.
B. pH 7.30 and HCO₃⁻ 20 mEq/L. While this shows partial improvement, the pH remains below 7.35, indicating ongoing mild acidosis. The bicarbonate level is still below normal, suggesting that buffering capacity is not yet fully restored. Additional treatment is required to completely normalize acid-base balance.
C. pH 7.38 and HCO₃⁻ 24 mEq/L. A pH of 7.38 falls within the normal range (7.35–7.45), indicating that acidosis has resolved. The bicarbonate level of 24 mEq/L is within normal limits, confirming that the body’s buffering system has been restored. These values suggest that ketoacidosis has resolved, and treatment has been effective.
D. pH 7.20 and HCO₃⁻ 15 mEq/L. A pH of 7.20 indicates severe metabolic acidosis, and a bicarbonate level of 15 mEq/L shows a significant loss of buffering capacity. These values suggest uncontrolled DKA or worsening acidosis, requiring urgent intervention with continued insulin therapy, fluid resuscitation, and electrolyte replacement.

Explanation

Place the call light within the client's reach. The client has undergone surgery on the left hemisphere of the brain, which controls speech and motor function on the right side. This may lead to temporary weakness or speech difficulties, making it essential to ensure easy access to the call light for assistance.
Use a word board to help the client communicate. Damage to the left hemisphere can result in Broca aphasia, where the client has difficulty producing speech but can still understand language. A word board or communication aid allows the client to express needs effectively despite speech limitations.
Cerebral perfusion pressure. Monitoring cerebral perfusion pressure (CPP) is essential after brain surgery to ensure the brain is receiving adequate blood flow. Low CPP can lead to ischemia, while high CPP may indicate increased intracranial pressure (ICP), both of which can result in serious complications.
Level of consciousness. Assessing neurological status frequently helps detect early signs of deterioration, such as worsening intracranial pressure, cerebral edema, or postoperative bleeding. Changes in alertness, responsiveness, or confusion may indicate a need for urgent intervention.
Broca aphasia. Since the left hemisphere controls speech production, surgery in this area may cause Broca aphasia, where the client understands language but struggles to form words or complete sentences. The use of alternative communication methods is necessary to assist the client in expressing their needs.
Prepare the client to return to surgery. There is no indication of complications requiring an immediate return to the operating room. The estimated blood loss (100 mL) is minimal, and vital signs remained stable throughout the procedure.
Give ibuprofen as ordered. Ibuprofen (a nonsteroidal anti-inflammatory drug - NSAID) is contraindicated postoperatively because it can increase the risk of bleeding by inhibiting platelet function. Acetaminophen is typically preferred for pain control.
Elevate the head of the bed to 45 degrees. After brain surgery, the head of the bed should be elevated to 30 degrees, not 45 degrees. This optimizes cerebral venous drainage while preventing excessive intracranial pressure (ICP) changes that could impair perfusion.
White blood cell count. WBC count may be monitored for infection, but immediate concerns after brain surgery focus on neurological status and cerebral perfusion rather than infection unless symptoms of fever or worsening condition develop.
Pupil response. While pupil assessment is a key neurological parameter, it is more relevant for clients at risk of brain herniation or severe ICP elevation. In this case, monitoring level of consciousness and cerebral perfusion pressure takes priority.
Deep tendon reflexes. Reflex testing is not a primary concern after brain surgery unless there are signs of spinal cord involvement or a progressive neurological disorder. Monitoring motor function and speech ability is more relevant.
Myasthenia gravis. Myasthenia gravis is an autoimmune neuromuscular disorder that causes muscle weakness but is unrelated to brain tumor removal.
Cushing response. Cushing's response is a late sign of increased intracranial pressure (ICP), characterized by hypertension, bradycardia, and irregular respirations. The client has no signs of worsening ICP at this time.
Hydrocephalus. Hydrocephalus is excess cerebrospinal fluid (CSF) accumulation, which typically requires a shunt or external ventricular drain (EVD). There is no indication of CSF buildup in this client.
