A client is on a ventilator. Alarms are sounding, indicating an increase in peak airway pressure. The nurse assesses first for what?
Malfunction of the alarm button.
A cut or slice in the tubing from the ventilator.
Higher than normal endotracheal cuff pressure.
A kink in the ventilator tubing.
The Correct Answer is D
Choice A Reason:
Malfunction of the alarm button is unlikely to be the cause of increased peak airway pressure. The alarm is designed to alert the nurse to a problem with the ventilator or the patient’s airway, not to malfunction itself. Therefore, this is not the first thing the nurse should assess.
Choice B Reason:
A cut or slice in the tubing from the ventilator could cause a loss of pressure or air leak, but it would not typically result in increased peak airway pressure. Instead, it would likely cause a decrease in pressure and potentially trigger a different alarm.
Choice C Reason:
Higher than normal endotracheal cuff pressure can contribute to increased peak airway pressure. However, it is not the most immediate concern compared to a kink in the tubing, which can completely obstruct airflow and rapidly compromise the patient’s ventilation.
Choice D Reason:
A kink in the ventilator tubing is a common and immediate cause of increased peak airway pressure. It obstructs the flow of air, leading to a buildup of pressure in the system. This is the first thing the nurse should assess and correct to ensure the patient is receiving adequate ventilation.

Correct Answer is B
Explanation
Choice A Reason:
Documenting that the nasogastric tube is in the correct place is not appropriate in this scenario. The normal pH range for gastric contents is typically between 1.5 and 3.5. A pH of 7.35 is much higher than this range, indicating that the tube may not be in the stomach. Therefore, documenting the tube as correctly placed could lead to potential complications, such as improper feeding or medication administration.
Choice B Reason:
Notifying the health care provider is the correct action. A pH of 7.35 suggests that the nasogastric tube may be misplaced, possibly in the respiratory tract or another non-gastric location. Immediate notification of the health care provider is crucial to prevent any adverse outcomes and to take corrective measures, such as confirming placement with an X-ray or re-inserting the tube.
Choice C Reason:
Checking for placement by auscultating for air injected into the tube is not a reliable method for verifying nasogastric tube placement. While this method was traditionally used, it has been found to be inaccurate and is no longer recommended. The sound of air entering the stomach can be misleading and does not confirm correct placement.
Choice D Reason:
Retesting the pH using another strip is not the best immediate action. While it is important to ensure the accuracy of the pH reading, a pH of 7.35 is significantly outside the normal gastric range, and retesting is unlikely to yield a different result. The priority should be to notify the health care provider to address the potential misplacement of the tube.
Correct Answer is A
Explanation
Choice A Reason:
Place the client on aspiration precautions: Myxedema coma is a severe form of hypothyroidism that can lead to decreased mental function and a reduced level of consciousness. These conditions increase the risk of aspiration, which can lead to pneumonia and other complications. Therefore, placing the client on aspiration precautions is crucial to prevent these risks. Aspiration precautions may include elevating the head of the bed, monitoring swallowing ability, and providing thickened liquids if necessary.
Choice B Reason:
Turn the client every 4 hours: While turning the client regularly is important to prevent pressure ulcers, it is not the primary action needed for a client in a myxedema coma. The focus should be on stabilizing the client’s condition and preventing life-threatening complications such as aspiration, respiratory failure, and cardiovascular collapse.
Choice C Reason:
Check the client’s blood pressure every 2 hours: Monitoring vital signs, including blood pressure, is essential for clients in a myxedema coma. However, it is not the most critical action compared to preventing aspiration. Blood pressure should be monitored regularly, but the frequency can be adjusted based on the client’s condition and stability.
Choice D Reason:
Initiate measures to cool the client: Clients in a myxedema coma typically present with hypothermia (low body temperature), not hyperthermia (high body temperature). Therefore, initiating measures to cool the client would be inappropriate and could worsen their condition. Instead, measures to warm the client, such as using blankets and adjusting room temperature, are more appropriate.
