What are some common side effects of medication that a PCA should observe for?

The correct answer highlights some of the common side effects associated with medications, particularly those that may be administered by a Patient Care Assistant (PCA). Drowsiness, nausea, and confusion are well-documented reactions to various classes of medications, especially opioids and sedatives.

Understanding these side effects is crucial for a PCA, as they must monitor patients for any adverse reactions that could impact their recovery and general well-being. Drowsiness can impair a patient's ability to perform daily activities and increase the risk of falls. Nausea can affect a patient's hydration and nutritional intake, while confusion may indicate a more severe side effect or a potential adverse drug interaction. Being vigilant about these symptoms allows the PCA to provide timely and appropriate interventions, ensuring patient safety and comfort throughout the care process.
