A nurse is reinforcing teaching with a client who is receiving morphine via a patient-controlled analgesia (PCA) infusion device. Which of the following statements by the client indicates an understanding of the teaching?

A. This statement describes an action taken by the client and is considered objective information. It reports a measurable action rather than the client’s personal experience or feelings about their condition.
B. This is an objective finding, as it is a measurable and observable fact obtained through assessment. It
does not reflect the client’s perspective or self-reported symptoms.
C. It describes observable signs noted during the assessment and does not include any information shared by the client about how they feel.
D. It reflects the client’s personal experience of pain and provides context for the symptom, including the activity that triggered it. This type of information is essential in understanding the client’s condition from their perspective.

A. This statement pertains to the client's current state but does not represent an intervention taken by the nurse. It would be more appropriate for documentation in a narrative or assessment section rather than the intervention component.
B. This entry describes an outcome or finding related to the client’s condition rather than an intervention. While it is important data, it does not reflect an action taken by the nurse and thus would not be included in the intervention section.
C. It clearly describes a specific action taken by the nurse (administering medication) in response to the problem (nausea and vomiting). It directly addresses the client's needs and reflects an intervention aimed at treating the identified problem.
D. This statement indicates the problem or symptom that the client is experiencing but does not describe an intervention. While it is critical information for understanding the client’s condition, it belongs in the problem or assessment section rather than the intervention component.
