An ICU nurse is at the nurse's station when they suddenly hear their patient's ventilator alarming. Which actions should the nurse take when responding to ventilator alarms? Select all that apply.

Immediately silence the alarm so the patient can rest

Check the ventilator tubing connections

Assess the client's respiratory status

Adjust the ventilator settings to stop the alarm

Call the respiratory therapist

Answer and Explanation

Correct Answer : B,C,E

A. Immediately silence the alarm so the patient can rest: Silencing the alarm without first assessing the cause is unsafe and may delay recognition of life-threatening problems such as airway obstruction, disconnection, or high airway pressures. Ventilator alarms are safety mechanisms designed to alert to changes in ventilation or oxygenation and must never be ignored

B. Check the ventilator tubing connections: Disconnections, kinks, water accumulation, or loose tubing are common causes of ventilator alarms. Inspecting the circuit ensures that the patient remains connected to the ventilator and is receiving prescribed ventilation. A disconnection can rapidly lead to hypoxia, especially in critically ill ICU patients.

C. Assess the client's respiratory status: The priority is always to assess the patient first. Evaluate chest rise, work of breathing, oxygen saturation, breath sounds, and level of consciousness. Determining whether the patient is in distress guides immediate interventions, including manual ventilation if necessary.

D. Adjust the ventilator settings to stop the alarm: Ventilator settings should not be changed independently in response to an alarm without identifying the underlying cause and obtaining appropriate authorization. Arbitrary adjustment may worsen ventilation, cause barotrauma, or mask a serious clinical problem.

E. Call the respiratory therapist: After initial assessment and troubleshooting, involving the respiratory therapist is appropriate for persistent alarms or suspected ventilator malfunction. RTs have specialized expertise in ventilator management and can assist in correcting mechanical or setting-related issues while ensuring safe ventilation.

Correct Answer is C

Explanation

A. Call the provider to report that the reading is low and the patient needs 0.9% sodium chloride: A CVP of 12 mmHg is elevated, not low. Administering IV fluids in this situation could worsen fluid overload and exacerbate heart failure, making this action inappropriate.

B. Document the finding as within normal limits: Normal CVP ranges from 2–8 mmHg. A reading of 12 mmHg exceeds this range, indicating elevated right atrial pressure and potential fluid overload. Documentation without intervention would miss a critical opportunity to prevent complications.

C. Call the provider to report that the reading is high and the patient may need a furosemide: Elevated CVP suggests volume overload and increased right heart filling pressures. Reporting this finding allows the provider to evaluate the patient for interventions such as diuretics (e.g., furosemide) to reduce preload and manage congestive symptoms, which is the appropriate clinical action.

D. Document the finding as abnormal: While documentation is important, it is insufficient as a standalone action in the context of heart failure. Elevated CVP requires timely clinical assessment and provider notification to prevent worsening pulmonary congestion or systemic fluid overload.

A. Decreased breath sounds on the right B. Continuous bubbling in the water seal chamber C. Absence of tidaling in the water seal chamber D. A lack of drainage in the collection chamber

Correct Answer is A

Explanation

A. Decreased breath sounds on the right: Persistently decreased or absent breath sounds on the side of the pneumothorax after chest tube placement suggests that the lung may not have fully re-expanded or there may be obstruction, malposition, or kinking of the tube. This finding requires immediate reassessment and intervention to ensure effective lung re-expansion and adequate ventilation.

B. Continuous bubbling in the water seal chamber: Continuous bubbling may indicate an air leak, which is common immediately after chest tube insertion for pneumothorax. While it should be monitored, early continuous bubbling is expected and does not necessarily require urgent intervention unless it persists beyond the initial period or worsens.

C. Absence of tidaling in the water seal chamber: Tidaling reflects normal respiratory fluctuations in intrathoracic pressure. The absence of tidaling may indicate lung re-expansion, which is a desired outcome, or an obstruction in the tubing. The nurse should assess for tube patency, but this finding alone does not always indicate immediate danger.

D. A lack of drainage in the collection chamber: Minimal drainage is expected in a simple pneumothorax because the primary goal is evacuation of air, not fluid. Lack of drainage in the collection chamber immediately post-insertion is generally not concerning and does not require urgent intervention.
