#1
Which of the following is not a common indication for endotracheal intubation in critical care?
Severe anxiety
ExplanationIntubation is not typically done for anxiety but rather for airway protection or respiratory failure.
#2
What is the primary goal of mechanical ventilation in critical care?
To maintain oxygenation and ventilation
ExplanationMechanical ventilation aims to support gas exchange in the lungs to maintain proper oxygen levels and remove carbon dioxide.
#3
Which of the following is a common complication associated with central venous catheterization?
Infection
ExplanationInfections are a frequent risk with central venous catheters due to their invasive nature and prolonged use.
#4
What is the purpose of administering vasopressor medications in critical care?
To increase blood pressure
ExplanationVasopressors are used to elevate blood pressure in cases of shock or hypotension.
#5
What is the purpose of a bronchoscopy procedure in critical care?
To visualize the bronchi and lungs
ExplanationBronchoscopy allows direct visualization of the airways for diagnostic and therapeutic purposes.
#6
Which of the following is a potential complication of arterial line insertion in critical care?
Bleeding
ExplanationBleeding is a possible risk due to the puncture of an artery during insertion.
#7
Which of the following is not a typical nursing intervention for a patient in septic shock?
Providing oxygen therapy
ExplanationOxygen therapy is usually provided; other interventions focus on fluid resuscitation, antibiotics, and hemodynamic support.
#8
What is the primary goal of administering neuromuscular blocking agents (NMBAs) in critical care?
To facilitate mechanical ventilation
ExplanationNMBAs are used to paralyze skeletal muscles, facilitating mechanical ventilation in patients.
#9
What is the recommended initial treatment for a patient with suspected tension pneumothorax in critical care?
Insertion of a chest tube
ExplanationInserting a chest tube allows for the release of trapped air or fluid, relieving pressure within the pleural space.
#10
Which of the following is a typical nursing intervention to manage increased intracranial pressure (ICP) in critical care?
Avoiding sedation
ExplanationReducing sedation levels helps maintain neurological assessment accuracy and prevents further suppression of respiratory drive.
#11
Which of the following is a common nursing intervention for a patient receiving extracorporeal membrane oxygenation (ECMO) in critical care?
Administering anticoagulants
ExplanationAnticoagulants are necessary to prevent clot formation within the ECMO circuit.
