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. Assessing a client who experiences unilateral calf pain when ambulating.
Unilateral calf pain in a client who is ambulating can be indicative of a potential deep vein thrombosis (DVT), which is a serious condition that requires prompt assessment and intervention. DVTs are a risk after surgery, and early detection is crucial to prevent complications such as a pulmonary embolism. Assessing the client experiencing calf pain is the priority to determine the cause and initiate appropriate interventions.
B. Reassuring the partner of a client who sustained a closed head injury:
While providing support and reassurance to family members is important, it is not as urgent as assessing a client with potential signs of a DVT.
C. Taking a telephone prescription about a client who is to be transferred from PACU:
While obtaining and implementing orders in a timely manner is important, assessing and addressing a potential DVT takes precedence due to the immediate risk to the client's well-being.
D. Reinforcing a client’s dressing for the surgical site of an above-the-knee amputation:
Dressing reinforcement is important for wound care, but it is not as urgently needed as assessing a client with possible signs of a DVT. The assessment of calf pain takes priority.
Correct Answer is A
Explanation
A. Cooperating:Cooperating involves working together to find a mutually beneficial solution. In this case, the charge nurse resolves the conflict by allowing both nurses to go to lunch together and taking care of their clients, ensuring that both nurses’ needs are met.
B. Avoiding:Avoiding means ignoring the conflict or withdrawing from the situation. The charge nurse is not ignoring the conflict; rather, they are actively facilitating a resolution by allowing both nurses to take lunch together.
C. Compromising:Compromising involves both parties giving up something to reach a mutually acceptable solution. While the charge nurse is helping to resolve the conflict by allowing the nurses to go to lunch, it does not imply that either nurse has made a concession in their argument, making this option less accurate.
D. Competing:
Competing involves pursuing one's own concerns at the expense of others. It is a win-lose approach to conflict resolution. The charge nurse is not demonstrating a competitive approach in this scenario, as both nurses are accommodated to go to lunch together without one person's needs being prioritized over the other.
