Two critical care clients are under the nurse’s care. Which intervention should be implemented first?

• A. Assess level of consciousness and vital signs for both clients
• B. Administer analgesic for incisional pain
• C. Increase oxygen delivery
• D. Change ventilator settings

Answer: (A)

In critical care, the first move with two unstable patients is to quickly evaluate both to establish who is most at risk and to set baselines for monitoring. Assessing level of consciousness tells you how well the brain is being perfused and oxygenated, while checking vital signs gives you immediate information about airway, breathing, and circulation. This snapshot guides every subsequent action and helps you prioritize care for the patient in greatest need.

Acting first by analgesia misses the opportunity to address potential life-threatening issues and can mask changes in mental status or respiration. Increasing oxygen delivery or changing ventilator settings are important, but they should follow an initial assessment that reveals current oxygenation and ventilation needs. By confirming each patient’s status up front, you can determine who needs urgent intervention and what specific changes are needed next.
