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.
The Correct Answer is A
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 ["9"]
Explanation
Calculation:
Calculate the dopamine dose in mcg/min:
Dose = 2 mcg/kg/min
Weight = 60 kg
Dose per minute = 2 mcg/kg/min × 60 kg
= 120 mcg/min
Calculate the dopamine dose in mcg/hour:
Dose per hour = 120 mcg/min × 60 min/hour
= 7200 mcg/hour
Convert mcg to mg:
Dose per hour = 7200 mcg/hour / 1000 mcg/mg
= 7.2 mg/hour
Calculate the concentration of dopamine in the IV bag:
Dopamine: 400 mg
Solution: 500 mL
Concentration = 400 mg / 500 mL
= 0.8 mg/mL
Calculate the infusion rate in mL/hour:
Dose per hour: 7.2 mg/hour
Concentration: 0.8 mg/mL
Infusion rate = 7.2 mg/hour / 0.8 mg/mL
= 9 mL/hour
Correct Answer is B
Explanation
A. Turn off the pacemaker. Turning off the pacemaker is not appropriate because the client has a third-degree heart block, which means their heart is not conducting impulses properly. Disabling the pacemaker could lead to severe bradycardia or asystole. The goal is to troubleshoot the issue rather than stopping pacing altogether.
B. Check the sensitivity control. Loss of sensing means the pacemaker is not detecting the client's intrinsic heart activity, which can lead to inappropriate pacing or failure to respond to the heart’s natural rhythm. Adjusting the sensitivity setting ensures that the pacemaker can recognize the client's heartbeats and pace appropriately. This is the first step in troubleshooting pacemaker malfunctions related to sensing issues.
C. Increase the milliamps (mA). Increasing the milliamps (mA) is used when there is failure to capture, meaning the pacemaker is delivering impulses but the heart is not responding. Since the problem here is failure to sense, adjusting the sensitivity setting is the correct first action.
D. Position the client on the left side. Repositioning the client is sometimes recommended for displacement of a transvenous pacemaker lead, but in this case, the issue is sensing failure, not lead displacement. Checking and adjusting the pacemaker settings is a more appropriate first step before considering repositioning.
