A client reads the nutritional chart and follows it accurately. The nurse also notes that the client understands the need for a balanced diet and its relationship with quick recovery. In which domain is the client demonstrating successful learning?

Affective

Psychomotor

Interpersonal

Cognitive

Answer and Explanation

The Correct Answer is D

Choice A reason: The affective domain involves emotions and attitudes, such as valuing a diet’s importance. The client’s understanding of the diet’s role in recovery indicates knowledge, not emotional engagement. While they may value the diet, the question emphasizes understanding, which aligns with cognitive learning, not affective.

Choice B reason: The psychomotor domain involves physical skills, like preparing food or performing tasks. Following a nutritional chart accurately may involve actions, but the question highlights understanding the diet’s role in recovery, which is cognitive. Physical adherence is secondary to the mental comprehension described in the scenario.

Choice C reason: The interpersonal domain, not standard in learning taxonomies, may imply social skills. The client’s actions involve individual understanding and application of knowledge, not social interaction. The focus on understanding the diet’s impact on recovery points to cognitive learning, not interpersonal or social processes.

Choice D reason: The cognitive domain involves knowledge, comprehension, and application. The client’s ability to read, follow, and understand the nutritional chart’s role in recovery demonstrates cognitive learning. This includes processing information, understanding relationships, and applying knowledge to improve health outcomes, aligning with the scenario’s description of successful learning.

Correct Answer is A

Explanation

Choice A reason: Homeostasis is the body’s ability to maintain stable internal conditions, including fluid and electrolyte balance. Imbalances, like hypokalemia or hypernatremia, disrupt cellular function, potentially causing arrhythmias or neurological issues. Restoring homeostasis is the priority, as it addresses the root cause, ensuring proper organ function and preventing complications.

Choice B reason: Preventing infection is important but not the priority in fluid and electrolyte imbalances. Infections may occur secondary to other conditions, but the primary concern is correcting imbalances that affect cellular and organ function. Homeostasis must be achieved first to stabilize the client’s physiological state before addressing infection risks.

Choice C reason: Promoting mobility is relevant for overall health but not the priority in fluid and electrolyte imbalances. Imbalances can cause muscle weakness or arrhythmias, but restoring electrolyte levels takes precedence to ensure safe mobility. Without homeostasis, mobility efforts may be unsafe or ineffective due to physiological instability.

Choice D reason: Enhancing nutrition supports overall recovery but is secondary to correcting fluid and electrolyte imbalances. Nutritional deficiencies may contribute to imbalances, but the immediate goal is restoring homeostasis to prevent acute complications like cardiac or neurological dysfunction. Nutrition can be addressed once the client is stabilized.

A. pH 7.48, PaCO2 40 mmHg, HCO3- 24 mEq/L B. pH 7.30, PaCO2 30 mmHg, HCO3- 18 mEq/L C. pH 7.50, PaCO2 45 mmHg, HCO3- 30 mEq/L D. pH 7.35, PaCO2 38 mmHg, HCO3- 22 mEq/L

Correct Answer is B

Explanation

Choice A reason: pH 7.48, PaCO2 40 mmHg, HCO3- 24 mEq/L indicates alkalosis, not acidosis. Diabetic ketoacidosis (DKA) causes metabolic acidosis due to ketone accumulation, lowering pH and bicarbonate. Normal PaCO2 and HCO3- rule out DKA, as compensatory hyperventilation would lower PaCO2 in response to acidosis.

Choice B reason: pH 7.30, PaCO2 30 mmHg, HCO3- 18 mEq/L indicates metabolic acidosis with respiratory compensation. In DKA, ketone production lowers pH and bicarbonate, while hyperventilation reduces PaCO2 to compensate. These values align with DKA’s acid-base imbalance, reflecting the body’s attempt to correct acidosis through increased respiration.

Choice C reason: pH 7.50, PaCO2 45 mmHg, HCO3- 30 mEq/L indicates metabolic alkalosis, not acidosis. DKA causes acidosis from ketone accumulation, not alkalosis. Elevated bicarbonate and normal PaCO2 suggest a different condition, like vomiting-induced alkalosis, making this inconsistent with the metabolic acidosis seen in DKA.

Choice D reason: pH 7.35, PaCO2 38 mmHg, HCO3- 22 mEq/L indicates normal acid-base balance. DKA results in metabolic acidosis with low pH and bicarbonate due to ketone production. Normal values do not reflect the acidotic state of DKA, where compensatory mechanisms would alter PaCO2 and HCO3- significantly.
