The nurse is caring for a client receiving mechanical ventilation. The nurse hears the low-pressure alarm sound. After checking the client and ventilator, the nurse cannot determine the source of the alarm. What should the nurse do next?
Notify the health care provider
Insert an oral airway to prevent the client from biting the tube
Suction the client and reset the alarm
Disconnect the client from the ventilator and use a manual resuscitation bag
The Correct Answer is D
A. Notify the healthcare provider: While notifying the healthcare provider may eventually be necessary, the first priority is to ensure the client's airway is protected and they are receiving adequate ventilation. The provider can be notified after immediate interventions have been made to stabilize the patient.
B. Insert an oral airway to prevent the client from biting the tube: Inserting an oral airway may be necessary if the client is biting the endotracheal tube, but this is unlikely the first action needed in response to a low-pressure alarm. If the client is not biting the tube, this action will not address the potential causes of the low-pressure alarm, such as a disconnection, leak, or circuit issue.
C. Suction the client and reset the alarm: While suctioning is an important intervention if secretions are the cause of ventilation issues, it is not the first action when the source of the low-pressure alarm is unclear. If a disconnection or leak is the issue, suctioning will not resolve the problem, and the nurse risks delaying appropriate action to address the source of the alarm. The priority is ensuring the client’s ventilation is not compromised, which is best accomplished by using a manual resuscitation bag until the problem is identified and corrected.
D. Disconnect the client from the ventilator and use a manual resuscitation bag: If the source of the low-pressure alarm cannot be identified after checking the client and the ventilator, the first priority is to ensure that the client continues to receive adequate ventilation. Disconnecting the client from the ventilator and using a manual resuscitation bag (Ambu bag) allows for immediate support of the patient's ventilation while the nurse investigates the cause of the alarm. This ensures the client's oxygenation and ventilation needs are met until the problem is resolved. It is critical to address any potential loss of positive pressure or leaks in the ventilator system promptly to avoid respiratory distress or failure.

Correct Answer is C
Explanation
A. Hyperglycemia:
Although hyperglycemia can occur as a result of stress or corticosteroid use during the treatment of GBS (such as in the case of plasma exchange or IV immunoglobulin (IVIG) therapy), it is not the primary complication associated with GBS. While hyperglycemia requires monitoring and management, respiratory failure is a more immediate and critical concern.
B. Urinary retention:
Urinary retention can occur in some clients with neurologic disorders like GBS, but it is not as life-threatening as respiratory failure. The autonomic nervous system, which controls bladder function, may be affected, but urinary retention is usually manageable with intermittent catheterization or other interventions. It does not carry the same immediate risks to life or organ function as respiratory failure.
C. Respiratory failure:
In Guillain-Barré syndrome (GBS), the immune system attacks the peripheral nervous system, which can lead to progressive muscle weakness and paralysis. The most significant and potentially life-threatening complication of GBS is respiratory failure. This occurs because the paralysis can affect the muscles involved in breathing, including the diaphragm and intercostal muscles, leading to impaired ventilation. As the weakness progresses, the client may become unable to maintain effective breathing, requiring mechanical ventilation. Monitoring for signs of respiratory distress (e.g., increasing work of breathing, tachypnea, decreased breath sounds, or a drop in oxygen saturation) is critical in GBS, especially during the acute phase of the disease.
D. Hypertension:
Hypertension may be seen in some cases of GBS, particularly during the early stages of the disease, due to the autonomic dysfunction that can result from nerve involvement. However, hypotension (low blood pressure) is more commonly associated with the autonomic dysfunction in GBS rather than hypertension. Regardless, respiratory failure remains the most urgent complication to monitor for in clients with GBS.
Correct Answer is A
Explanation
A. Hand washing before and after client contact: The most important infection control guideline when caring for a client with acute respiratory distress syndrome (ARDS) who is on a ventilator is hand hygiene. This is because ventilated patients are at high risk for ventilator-associated pneumonia (VAP) and other infections. Hand washing is the most effective method of preventing the spread of pathogens that could lead to nosocomial infections. The nurse should perform proper hand hygiene both before and after any patient interaction, as this is critical in preventing the transmission of bacteria or viruses, especially in patients with compromised respiratory systems.
Explanation of each option:
B. Placement of an indwelling urinary catheter using sterile technique:
While using sterile technique when placing an indwelling urinary catheter is essential to prevent urinary tract infections (UTIs), it is not the top priority for infection control in this situation. The primary concern for infection in ARDS patients who are on mechanical ventilation is preventing respiratory infections, particularly ventilator-associated pneumonia (VAP). Although catheter-associated infections should be prevented, the most immediate concern is preventing respiratory-related infections.
C. Initiate neutropenic precautions:
Neutropenic precautions are important for patients who have immunocompromised conditions (such as those undergoing chemotherapy or with bone marrow suppression) to protect them from infections. However, ARDS does not necessarily compromise the immune system in the same way. The priority infection control measure for a patient on a ventilator with ARDS is preventing respiratory infections. Therefore, neutropenic precautions would not be the most relevant or highest priority in this case.
D. Clean technique with central IV line care:
Maintaining clean technique with central intravenous (IV) line care is important to prevent infections, such as central line-associated bloodstream infections (CLABSI). However, the most critical infection control measure for a patient on a ventilator with ARDS is still to focus on preventing respiratory infections, particularly ventilator-associated pneumonia (VAP). While IV line care is important, it is secondary to preventing respiratory tract infections in this scenario.
