The nurse is monitoring for signs of increased intracranial pressure (ICP) in a client who attempted suicide by jumping from a tenth floor balcony. The client is intubated and mechanically ventilated. Which intervention should the nurse implement to minimize rises in ICP?

A. Obtain a chest x-ray to verify endotracheal tube location. A chest x-ray is the gold standard for confirming ETT placement, but it is not the first step. Immediate bedside assessment is needed to ensure the tube is correctly positioned before relying on imaging. If the tube is misplaced in the esophagus, waiting for an x-ray could delay necessary corrections.
B. Call the respiratory therapist (RT) to verify tube placement. The nurse should first perform a rapid bedside assessment before consulting the RT. While RTs assist in confirming placement, the nurse is responsible for the initial verification of breath sounds, chest rise, and end-tidal CO₂ (ETCO₂) readings. Any concerns should be addressed immediately.
C. Instill normal saline into the endotracheal tube for suctioning. Instilling saline before suctioning is not recommended, as it can promote aspiration, decrease oxygenation, and increase infection risk. The priority is confirming that the tube is properly placed before performing any interventions such as suctioning.
D. Auscultate for breath sounds bilaterally in all lung fields. The first action after ETT placement is to auscultate bilateral breath sounds to confirm proper tube positioning. If the tube is misplaced in the esophagus, breath sounds will be absent or diminished bilaterally. If placed too deep, breath sounds may be absent on one side, indicating mainstem bronchus intubation. This immediate assessment helps identify misplacement before obtaining a chest x-ray.

A. Narrowed pulse pressure, presence of 3+ femoral pulses, apneic episodes. Narrowed pulse pressure is consistent with hypovolemic shock, but 3+ femoral pulses are not expected, as shock leads to weak, thready pulses due to reduced perfusion. Apneic episodes typically occur in the late stages of shock, not in the early or progressive stages.
B. Widening pulse pressure, muffled heart sounds, presence of atrial gallop. A widening pulse pressure and muffled heart sounds are more indicative of cardiac tamponade, not hypovolemic shock. Hypovolemic shock is characterized by a narrowing pulse pressure due to a drop in systolic blood pressure while diastolic pressure remains relatively stable.
C. Increased heart rate, lowered systolic reading, peripheral extremity mottling. Tachycardia is an early compensatory response to hypovolemia as the body attempts to maintain cardiac output. As shock progresses, systolic blood pressure drops due to inadequate circulating volume. Peripheral extremity mottling occurs as the body shunts blood to vital organs, reducing perfusion to the skin. These signs are characteristic of progressive hypovolemic shock.
D. Irregular heart rate, elevated diastolic reading, increased respiratory rate. An irregular heart rate is not a primary indicator of hypovolemic shock. While respiratory rate increases in response to decreased oxygen delivery, an elevated diastolic reading is uncommon, as diastolic pressure tends to stay stable or decrease slightly with ongoing hypovolemia.
