A nurse is assessing a client who is postoperative following a craniotomy. Which of the following findings requires intervention by the nurse?

A. Sub-sternal chest pressure: Sub-sternal chest pressure can be a sign of cardiac issues such as angina or myocardial infarction, not typically seen with ARDS. ARDS primarily involves respiratory symptoms such as severe hypoxemia and increasing dyspnea.

B. O2 sats at 75% on 100% Fi02: A significant decrease in oxygen saturation despite 100% oxygen administration is a hallmark sign of ARDS. This condition is characterized by severe, refractory hypoxemia, where the lungs are unable to provide adequate oxygen to the bloodstream even with high levels of oxygen.

C. Anxiety and restlessness: Anxiety and restlessness are common in ARDS due to hypoxia and respiratory distress. As the body struggles to get sufficient oxygen, the client may experience increased anxiety, restlessness, and discomfort, which are signs of worsening respiratory function.

D. Increasing dyspnea: Increasing dyspnea, or difficulty breathing, is a classic symptom of ARDS. As the condition progresses, the client’s ability to breathe becomes more labored due to inflammation and fluid buildup in the alveoli, leading to worsening oxygenation.

E. Pitting edema to ankles: Pitting edema to the ankles is more commonly associated with heart failure or fluid retention rather than ARDS. ARDS typically causes fluid buildup in the lungs rather than peripheral edema, which occurs in cases of circulatory problems.

A. Insert a padded tongue blade into the client's mouth: Inserting a tongue blade can cause harm, such as damaging the client's teeth or mouth or causing them to bite down on the blade, leading to injury. It is not recommended during a seizure.

B. Place a pillow under the client's head: Placing a pillow under the client’s head helps protect it from injury during the clonic phase of a seizure. This is the most appropriate and safest action to prevent head trauma while the client is experiencing a seizure.

C. Gently restrain the client's extremities: Restraint during a seizure can lead to injury and should be avoided. The priority is to allow the seizure to occur without interference, ensuring the client’s safety by preventing injury from the environment.

D. Apply a face mask for oxygen administration: Oxygen may be indicated if the client shows signs of respiratory distress, but applying a face mask immediately is not the priority. Ensuring safety during the seizure (e.g., protecting the head) is more important in the initial response.
