Final answer:
The nursing student omitted the Planning step of the nursing process, which involves formulating goals and identifying intervention strategies before administering medication.
Step-by-step explanation:
The nursing student omitted the Planning step of the nursing process. While they did assess the client's pain, prepared and administered medication, and evaluated the client's response to the pain medication, they did not mention any planning which should include formulating nursing goals for pain management and identifying intervention strategies prior to administering medication.
The nursing process is a critical thinking method used by nurses to ensure quality patient care and includes the following steps: Assessment, Planning, Intervention, and Evaluation.
The student included Assessment (noting the client's pain), Intervention (administering pain medication), and Evaluation (checking if the pain subsided), but did not articulate any Planning phase, which would typically include setting goals and expected outcomes before proceeding with the intervention.
