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.
Apply a high-flow oxygen by face mask.
Obtain a chest tube insertion kit.
Withhold narcotic pain medication.
Elevate the head of the bed 45 degrees.
Place client in Trendelenburg position.
Correct Answer : A,B
A. Apply high-flow oxygen by face mask. The client is in respiratory distress with absent breath sounds over the left lung field, which is highly suggestive of a pneumothorax or hemothorax. High-flow oxygen helps improve oxygenation while preparing for definitive intervention. In cases of tension pneumothorax, oxygen can help reduce hypoxia until a chest tube or needle decompression is performed.
B. Obtain a chest tube insertion kit. Absent breath sounds on one side following chest trauma strongly suggest a pneumothorax or hemothorax, requiring immediate chest tube placement to re-expand the lung and restore normal ventilation. The nurse should ensure that the equipment for thoracostomy (chest tube insertion) is readily available for the healthcare provider.
C. Withhold narcotic pain medication. Pain control is important in trauma patients, as uncontrolled pain can lead to shallow breathing, atelectasis, and respiratory complications. Narcotics should be used cautiously in clients with respiratory distress, but they are not contraindicated if given at appropriate doses with close monitoring.
D. Elevate the head of the bed 45 degrees. Clients with respiratory distress should be positioned with the head of the bed elevated to improve lung expansion. However, in a suspected pneumothorax, the priority is oxygenation and chest tube insertion. If there is hemodynamic instability, the client may require a flat or semi-Fowler’s position instead.
E. Place client in Trendelenburg position. The Trendelenburg position (head down, feet up) is not appropriate in chest trauma patients. This position can increase intra-abdominal pressure, worsen breathing difficulty, and impair lung expansion. It is typically avoided in clients with respiratory distress or suspected pneumothorax.

Correct Answer is D
Explanation
A. Observe vital signs sequences as a way of assessing for Cushing's triad. Cushing’s triad (hypertension with widened pulse pressure, bradycardia, and irregular respirations) is a late sign of increased intracranial pressure (ICP). While monitoring for it is important, early recognition and direct ICP monitoring are more effective in preventing deterioration.
B. Evaluate hourly urinary output. Mannitol is an osmotic diuretic that can cause significant diuresis, requiring close monitoring of urine output to prevent dehydration and electrolyte imbalances. However, assessing ICP is the priority because increased ICP can cause brain herniation, which is life-threatening.
C. Monitor arterial blood pressure. Dopamine is a vasopressor used to maintain cerebral perfusion pressure (CPP), which is crucial in head injury management. While blood pressure monitoring is essential, directly assessing ICP ensures that treatment is effective in preventing secondary brain injury.
D. Assess intracranial pressure following intracranial transducer placement. The highest priority is monitoring ICP immediately after placement to detect dangerous elevations that could lead to herniation. The intraventricular catheter provides real-time pressure readings, guiding interventions like mannitol administration and blood pressure control to optimize cerebral perfusion and prevent worsening neurological damage.
Correct Answer is ["C","D"]
Explanation
A. Low PaO2. Clients with DKA do not typically have significant hypoxemia unless there is concurrent respiratory compromise. The primary issue in DKA is metabolic acidosis rather than oxygenation.
B. Low lactic acid. Lactic acidosis is not a hallmark of DKA. Instead, DKA is characterized by ketone production from fatty acid metabolism. Elevated lactic acid is more common in conditions like sepsis or tissue hypoxia.
C. Low pH. Diabetic ketoacidosis (DKA) causes metabolic acidosis due to the accumulation of ketone bodies, leading to a pH below 7.35. The absence of insulin results in unregulated lipolysis and ketogenesis, significantly lowering blood pH.
D. Low bicarbonate (HCO3-). In metabolic acidosis, bicarbonate acts as a buffer and gets depleted while neutralizing excess acids. Clients with DKA typically have a bicarbonate level below 18 mEq/L (18 mmol/L), confirming metabolic acidosis.
E. High PaCO2. In metabolic acidosis, respiratory compensation leads to hyperventilation (Kussmaul respirations), causing PaCO2 to decrease as the body attempts to blow off excess CO2 to normalize pH.
