The PN Identifies that the client is having a tonic-clonic seizure. The oxygen saturation is 40% and the respiratory rate is 4 breaths/min. The PN calls for help and 2 other PNs enter the room. Which three actions will the PN anticipate taking next?

This is the correct answer because it is the most important and relevant action that the PN should do for a postoperative patient with a PCA machine. A PCA machine is a computerized device that allows the patient to self-administer a preset dose of pain medication, usually an opioid, by pressing a buton. The PCA machine is attached to an intravenous (IV) line that delivers the medication directly into the bloodstream. The PCA machine can provide effective and individualized pain relief for postoperative patients, as well as increase their sense of control and satisfaction¹².

The PN should assess the pain management response of the postoperative patient with a PCA machine by monitoring their pain level, vital signs, oxygen saturation, sedation level, and side effects. The PN should use a valid and reliable pain scale, such as the numeric rating scale (NRS) or the visual analog scale (VAS), to measure the patient's pain intensity and relief. The PN should also check the settings and functioning of the PCA machine, such as the dose, lockout interval, and limit. The PN should document and report the patient's pain management response and any problems or complications with the PCA machine to the health care provider.

- Medication administration is a process that involves prescribing, dispensing, and giving medications to patients. It is a critical and complex task that requires accuracy, safety, and adherence to the rights of medication administration, such as the right patient, right drug, right dose, right route, right time, right documentation, and right response.
- When a male client tells the practical nurse (PN) that the pill he has been taking at home is a different color and size than the one the PN is trying to give him now, this may indicate a potential medication error

or discrepancy. A medication error is any preventable event that may cause or lead to inappropriate medication use or patient harm. A medication discrepancy is any difference between the current and previous medication regimens of a patient.
- The PN should respond to the client's concern by telling him that the PN will verify that the dispensed medication is a valid prescription. This means that the PN will check the medication label, the medication order, and the medication administration record (MAR) to confirm that the medication given to the client matches the one prescribed by the healthcare provider. The PN will also compare the dispensed medication with a drug reference guide or a picture of the medication to ensure that it is the correct drug and dosage form. The PN will also report any suspected errors or discrepancies to the healthcare provider or the pharmacy for clarification or correction.

- Options A, B, and D are incorrect answers, as they do not reflect the appropriate or responsible actions for the PN to take when faced with a possible medication error or discrepancy.
