Which of the following is an appropriate modifier used in NANDA-I nursing diagnoses?

Choice A rationale

The diagnostic phase of the nursing process, which involves developing nursing diagnoses, fundamentally relies on the critical analysis and synthesis of subjective and objective assessment data. This systematic process allows the nurse to identify patient health problems or potential risks, formulating a list of clinical judgments (nursing diagnoses) that describe the human response to health conditions/life processes. This action is the intellectual foundation for planning care.

Choice B rationale

Recording intake and output is an implementation activity, specifically a form of data collection and monitoring that occurs after the initial assessment and diagnosis phases. While essential for tracking fluid balance and evaluating interventions, it does not represent the cognitive step of data analysis and problem formulation which defines the development of a nursing diagnosis. It is part of ongoing assessment and evaluation.

Choice C rationale

Administering prescribed medications falls under the implementation phase of the nursing process, where the nurse executes the planned interventions designed to achieve patient outcomes. This action is based upon, but distinct from, the diagnostic step which precedes it; the diagnosis informs why the medication is necessary, but the administration itself is the execution of a medical or nursing order.

Choice D rationale

Evaluating patient progress toward goals is the final phase of the nursing process, evaluation. This step compares the patient's actual outcomes with the expected outcomes established in the planning phase, determining the effectiveness of the care plan. It utilizes the nursing diagnosis but is not the process of formulating the diagnosis itself, which is completed earlier.

Choice A rationale

Vomiting 300 cc of green emesis is objective data because it is a measurable and observable sign of nausea, directly verifiable by the nurse. The volume (300 cc) and characteristic (green emesis) are quantifiable physical findings that can be used to assess the severity of the patient's condition, providing evidence beyond the patient's subjective report.

Choice B rationale

Blood pressure of 116/72 mmHg is objective data, a measurable vital sign, but it's often an expected finding (normal range typically <120/80) that doesn't specifically relate to or confirm nausea, though hemodynamic changes can occur with severe vomiting. While objective, it's a general assessment parameter rather than a direct indication of the symptom of nausea.

Choice C rationale

Hyperactive bowel sounds are objective data that are audible and verifiable by the nurse upon auscultation. Increased peristaltic activity is often associated with gastrointestinal irritation or rapid transit, which can be a physical manifestation related to the underlying physiological disturbance causing the subjective sensation of nausea, providing objective evidence.

Choice D rationale

Patient self-report ("the patient reports nausea") is the definition of subjective data. This information is based on the patient's personal experience and perception, which is crucial for assessment but cannot be directly observed or measured by the nurse. It is the chief complaint, not the objective proof.
