Which action should the practical nurse (PNA) prioritize for postoperative patient with a PCA (Patient- Controlled Analgesia) machine?

A. Coffee-ground secretions could indicate gastrointestinal bleeding, which is concerning. However, if the patient is on a PCA machine, managing and assessing pain control is a higher immediate priority. B. Nasogastric suctioning is important but does not take priority over ensuring that the PCA machine is effectively managing the patient's postoperative pain, especially when PCA usage can have serious implications on the patient's comfort and recovery. C. The primary purpose of the PCA machine is to manage postoperative pain effectively. The nurse must frequently assess the patient's pain level, response to the PCA, and any potential complications, such as over- or under-sedation, to ensure optimal recovery. D. If the pain is not being adequately controlled, reporting this is crucial. However, the first action is to assess how the patient is responding to pain management interventions with the PCA machine, which allows for the most appropriate follow-up.
