A patient is on the ventilator and a high-pressure alarm sounds. The nurse should assess for which of these possible causes for the alarm?
The patient may need suctioning
The patient extubated himself
The ventilator tubing may be disconnected.
The cuff at the end of the endotracheal tube is deflated.
The Correct Answer is A
A. The patient may need suctioning:
A high-pressure alarm indicates increased resistance to airflow, which could be caused by secretions or mucus in the airways. Suctioning is the appropriate intervention to clear the airways of excess secretions, reducing airway resistance and preventing the high-pressure alarm.
B. The patient extubated himself:
If the patient extubates himself (removes the endotracheal tube), this may result in a low-pressure alarm, not a high-pressure alarm. The low-pressure alarm is triggered when there is a loss of pressure within the ventilator circuit due to disconnection or extubation.
C. The ventilator tubing may be disconnected:
If the ventilator tubing is disconnected, it is more likely to trigger a low-pressure alarm, indicating a loss of pressure in the ventilator circuit. This is not the primary cause of increased resistance seen with a high-pressure alarm.
D. The cuff at the end of the endotracheal tube is deflated:
A deflated cuff can lead to air leakage around the endotracheal tube but is not the primary cause of increased airway resistance seen with a high-pressure alarm. It may cause a low-pressure alarm if cuff pressure is monitored.

Correct Answer is A
Explanation
A. The patient’s paralyzing agent dose is adequate, but needs to be given more often.
In a Train-of-four (TOF) assessment, four stimuli are delivered in rapid succession, and the response is observed. The number of twitches in the patient's thumb indicates the degree of neuromuscular blockade. In this case, if the patient's thumb twitches three times, it suggests that there is still some residual neuromuscular blockade, and the paralyzing agent dose is adequate. However, the frequency of administration may need to be increased to maintain the desired level of paralysis or neuromuscular blockade.
B. The patient’s paralyzing agent dose is too low and needs to be increased:
This would be indicated if there were fewer than three twitches in response to the TOF assessment.
C. The patient’s paralyzing agent dose is appropriate and does not need to be changed:
The response of three twitches suggests that there is still some neuromuscular blockade, so the dose or frequency may need adjustment.
D. The patient’s paralyzing agent dose is too high and needs to be reduced:
If there were no twitches or a complete absence of twitches, this might suggest an excessive dose. However, three twitches indicate some degree of neuromuscular blockade.
Correct Answer is B
Explanation
A. “Check your oxygen equipment once each week.”
Checking the oxygen equipment once a week is insufficient. The equipment should be regularly inspected for safety, including tubing, connections, and the condition of the oxygen concentrator or tank.
B. “Do not adjust the oxygen flow rate.”
The nurse should include in the teaching that the client should not adjust the oxygen flow rate without consulting their healthcare provider. Adjusting the oxygen flow rate without proper guidance can lead to inappropriate oxygen delivery, which may be harmful.
C. “Store unused oxygen tanks horizontally.”
Oxygen tanks should be stored in an upright position to prevent damage to the tank valve. Storing them horizontally can increase the risk of leaks or damage.
D. “Keep wool blankets on your bed.”
Wool blankets and other items that generate static electricity should be avoided near oxygen equipment, as they can increase the risk of fire. The client should be advised to use non-static bedding and clothing.
