The nurse knows that many medications given to clients have predictable, secondary effects which may be harmful or may be beneficial. The nurse always includes these effects in client teaching.

C. Regular assessment of the IV site is crucial to detect early signs of infiltration. Signs of infiltration include swelling, coolness, pain, or blanching around the insertion site. Assessing the site allows nurses to intervene promptly if infiltration occurs, preventing further complications such as tissue damage or fluid overload.

A. Flushing the IV catheter with normal saline helps to maintain patency and prevent blockage of the catheter. It also ensures that medications are effectively delivered into the bloodstream. While this action is important for maintaining the function of the IV catheter, it primarily addresses patency rather than preventing infiltration directly.

B. Securing the IV catheter to the extremity with a securement device (such as tape or a transparent dressing) helps prevent accidental dislodgement or movement of the catheter. This reduces the risk of

mechanical irritation at the insertion site, which can contribute to infiltration. Proper securement also ensures that the catheter remains in place during movement or patient activities.

D. Proper technique during catheter insertion helps reduce the risk of infection and subsequent complications, but it also indirectly contributes to preventing infiltration. Contamination during insertion can lead to inflammation or infection at the site, which may increase the risk of infiltration due to compromised tissue integrity.

A. Restlessness and agitation in nonverbal clients can often be exacerbated by environmental factors such as noise, bright lights, or unfamiliar surroundings. By reducing environmental stimuli, such as dimming lights, minimizing noise, and providing a calm atmosphere, the nurse can help alleviate agitation and promote a more comfortable environment for the client.

B. Suctioning the oropharynx is not typically the first action unless there is a clear indication that airway obstruction or secretion management is contributing to the client's agitation. It is important to first assess whether there are signs of respiratory distress or airway compromise before performing suctioning.

C. Assessing pulse oximetry is important for monitoring oxygen saturation levels, especially if there are concerns about respiratory distress or inadequate oxygenation. However, it is not typically the first action when a client is restless and agitated unless there are specific indications or signs suggesting respiratory compromise.

D. Administering oxygen may be necessary if there are signs of hypoxia or respiratory distress contributing to the client's agitation. However, without assessing the client's oxygenation status first, administering oxygen as the initial action may not address the underlying cause of agitation.
