Question 1

Which device is used to continuously monitor a patient’s blood pressure in a critical care setting?

Accepted Answer

Arterial line

Answer

Pulse oximeter

Answer

Electrocardiogram (ECG)

Answer

Central venous catheter

Question 2

What is the primary use of a central venous catheter in critical care?

Accepted Answer

To provide continuous intravenous fluid and medication administration

Answer

To monitor arterial blood pressure

Answer

To assess respiratory function

Answer

To perform echocardiography

Question 3

How do you manage and interpret data from advanced monitoring systems in a critically ill patient, and what steps do you take if the data suggests a deterioration in the patient's condition?

Accepted Answer

Review the data to identify potential causes of deterioration, adjust the monitoring settings as needed, and initiate appropriate interventions based on the patient's clinical status.

Answer

Immediately increase the dose of sedatives to manage patient discomfort.

Answer

Disconnect the monitoring equipment and perform a physical examination of the patient to reassess their condition.

Answer

Consult with a different specialist before making any adjustments to the monitoring settings.

Question 4

Describe the procedure for initiating and adjusting mechanical ventilation in a patient with acute respiratory distress syndrome (ARDS). What specific parameters and settings are critical to monitor and adjust in this scenario?

Accepted Answer

Start with a low tidal volume (6-8 mL/kg of ideal body weight) and moderate PEEP, and adjust settings based on arterial blood gas results and patient response.

Answer

Set the tidal volume to 10 mL/kg of ideal body weight and use a low PEEP setting.

Answer

Initiate mechanical ventilation with a high tidal volume and low respiratory rate, then gradually decrease the tidal volume.

Answer

Use a high PEEP setting and high respiratory rate initially to ensure adequate ventilation.

Question 5

Explain the process for performing and interpreting a bedside echocardiogram in a critically ill patient. What key findings would you look for, and how would these findings influence your management plan?

Accepted Answer

Evaluate the echocardiogram for signs of cardiac tamponade, left ventricular function, and right heart pressures, and use these findings to guide fluid management, inotropic support, and ventilation strategies.

Answer

Perform the echocardiogram focusing primarily on assessing left ventricular ejection fraction; adjust fluid resuscitation based on this measure alone.

Answer

Concentrate on detecting valvular heart disease and ignore other findings, as they are less critical in a critical care setting.

Answer

Only assess the presence of pericardial effusion and assume all other findings are normal.
