Concept Analysis Diagram – Acid Base Balance
Nursing Care
 Directed toward what contributes to a normal concept and is thereby related to all factors
involved in or with the concept. Not always needed to have a normal outcome.
Attributes
 Defining characteristics of the concept
 What property, quality, or data must be present for the concept to exist
Antecedents
 What precedes the concept for it to exist
 Events or incidents that must happen before the concept
Consequences
 Untoward events or outcomes that occur due to malfunction within the concept
 Positive events or outcomes that occur due to proper functioning within the concept
Interrelated Concept
 Concepts which can affect change in the other
 Concepts which work together to ensure a normal process
 Concepts which if depleted or impaired can cause a negative consequence in the other
Sub-Concept
 Critical components of major concept

Concept Analysis Diagram – Acid Base Balance
Explanation of Acid Base Balance Diagram:
Acid Base balance is the process of regulating the blood pH nursing care is directed at
maintaining a normal blood pH and preventing hypoxemia. The sub-concepts include
physiologic processes of acid base balance, compensatory mechanisms and consequences for
disruption. Interrelated concepts, which impact Acid Base Balance and which Acid Base Balance
impacts, are Fluid and Electrolyte Balance, Perfusion, Gas Exchange, Elimination, and Nutrition.
Attributes defining whether acid base balance exists at an optimum level are normal arterial
blood gas values and normal respiratory rate. Maintenance of acid base balance requires the
following antecedents: normal respiratory and renal function, normal digestive processes,
absence of vomiting and diarrhea, adequate nutrition and a normal anion gap. Positive
outcomes of acid base balance are balanced acid and base production, non-labored breathing
and normal activity/energy level for age. Some negative consequences of acid base imbalances
include anxiety, changes in level of consciousness, tingling of extremities, cardiac dysrhythmias,
and cellular destruction leading to death.
