ICU/Critical Care Monitoring ACTUAL
UPDATED QUESTIONS AND CORRECT
ANSWERS
1. What is the primary role of critical care nurses in ICU monitoring?
CORRECT ANSWERS✅✅ Critical care nurses continuously assess patients’ vital signs,
neurological status, hemodynamic parameters, and laboratory results. They identify early
signs of deterioration to prevent complications. Nurses collaborate with the multidisciplinary
team for timely interventions. Supportive care includes pain management, sedation, and
infection prevention. Patient education focuses on explaining procedures and expected
monitoring. Early detection of changes improves patient outcomes and survival. Continuous
documentation ensures accurate records for clinical decision-making.
2. How is invasive arterial blood pressure monitoring performed in ICU patients?
CORRECT ANSWERS✅✅ Invasive arterial monitoring involves placing a catheter in an
artery, commonly radial or femoral, connected to a pressure transducer. Nurses ensure
zeroing and calibration of the system for accurate readings. Monitoring provides continuous
real-time blood pressure and arterial blood sampling. Patient education focuses on explaining
the procedure and importance of limb immobilization. Supportive care includes infection
prevention, limb perfusion monitoring, and pain management. Early detection of blood
pressure fluctuations prevents organ ischemia. Continuous monitoring ensures patient safety
and accurate hemodynamic assessment.
3. What are the indications for central venous pressure (CVP) monitoring?
CORRECT ANSWERS✅✅ CVP monitoring assesses right atrial pressure, fluid status, and
cardiac preload. Indications include shock, severe dehydration, heart failure, and major
surgery. Nurses ensure proper catheter placement, zeroing of transducers, and aseptic
technique. Patient education focuses on explaining the catheter purpose and infection
prevention. Supportive care includes monitoring for complications like infection, thrombosis,
or pneumothorax. Early recognition of abnormal CVP values guides fluid management.
Continuous monitoring allows timely interventions and improved outcomes.
4. How is oxygen saturation monitored in critically ill patients?
CORRECT ANSWERS✅✅ Oxygen saturation is monitored using pulse oximetry, which
provides non-invasive continuous SpO₂ readings. Nurses ensure proper sensor placement,
calibration, and signal quality. Monitoring allows early detection of hypoxia and guides
oxygen therapy. Patient education includes explaining the device and reassuring the patient.
Supportive care includes adjusting oxygen delivery, monitoring respiratory status, and
, preventing skin breakdown at sensor site. Early detection of desaturation prevents organ
hypoxia and failure. Continuous monitoring ensures patient safety and effective respiratory
support.
5. What are the nursing priorities in monitoring patients with mechanical ventilation?
CORRECT ANSWERS✅✅ Priorities include monitoring respiratory rate, tidal volume,
airway pressures, oxygenation, and sedation levels. Nurses assess lung sounds, ABGs, and
signs of distress or ventilator asynchrony. Patient education focuses on explaining ventilation,
importance of sedation, and cooperation. Supportive care includes preventing ventilator-
associated pneumonia, skin breakdown, and maintaining comfort. Early recognition of
complications prevents hypoxia, barotrauma, and hemodynamic instability. Continuous
monitoring ensures ventilator settings are optimal and patient safety is maintained.
Collaboration with respiratory therapists ensures effective ventilation.
6. How is hemodynamic monitoring performed in ICU patients?
CORRECT ANSWERS✅✅ Hemodynamic monitoring includes arterial lines, central venous
catheters, pulmonary artery catheters, and non-invasive devices. Nurses assess blood
pressure, cardiac output, systemic vascular resistance, and heart rate. Monitoring guides fluid
management, medication titration, and detection of shock. Patient education focuses on
procedure explanation and importance of immobilization. Supportive care includes infection
prevention, aseptic technique, and patient comfort. Early detection of hemodynamic
instability prevents organ dysfunction. Continuous monitoring ensures accurate data for
timely interventions.
7. What are the clinical signs of early sepsis in ICU patients?
CORRECT ANSWERS✅✅ Early sepsis may present as fever, tachycardia, tachypnea,
hypotension, altered mental status, and oliguria. Nurses monitor vital signs, lab markers like
WBC and lactate, and organ function. Early identification allows timely fluid resuscitation,
antibiotic therapy, and hemodynamic support. Patient education includes explaining
interventions and importance of reporting new symptoms. Supportive care includes
hydration, infection control, and monitoring for organ dysfunction. Early recognition
prevents progression to septic shock and multi-organ failure. Continuous monitoring ensures
patient safety and effectiveness of interventions.
8. How is intracranial pressure (ICP) monitored in ICU patients?
CORRECT ANSWERS✅✅ ICP monitoring involves inserting a catheter into the ventricles,
subarachnoid space, or brain parenchyma connected to a transducer. Nurses ensure zeroing,
calibration, and aseptic technique. Monitoring detects early signs of increased ICP, guiding
interventions like hyperosmolar therapy or surgical decompression. Patient education focuses
