Twenty minutes after administering pain medication to the patient,the nurse asks if the patient's pain level has decreased. What phase of the nursing process does this demonstrate?

The correct answer is E: Evaluation. In this scenario, the nurse is assessing the effectiveness of the pain medication administered earlier. Evaluation is the phase of the nursing process where the nurse determines the patient's response to interventions. By checking if the patient's pain level has decreased, the nurse is evaluating the outcome of the implemented intervention (pain medication administration). The other choices are incorrect because: A: Assessment is the collection of data about the patient's condition, B: Analysis/Diagnosis involves identifying the patient's health problems, C: Planning is developing a plan of care based on the assessment and diagnosis, and D: Implementation is carrying out the planned interventions.
