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 B

Explanation

Choice A reason: Hypotension occurs in hypovolemic shock when blood volume loss exceeds 15–30%, indicating a later stage. Compensatory mechanisms like vasoconstriction maintain blood pressure initially. Tachycardia precedes hypotension as the body responds to reduced volume, making it a less early sign than increased heart rate.

Choice B reason: Tachycardia is the earliest sign of hypovolemic shock, occurring with 5–15% blood volume loss. The sympathetic nervous system increases heart rate to compensate for reduced cardiac output, maintaining perfusion. This precedes other signs like hypotension or oliguria, making it the first detectable indicator in shock assessment.

Choice C reason: Cool, clammy skin results from vasoconstriction in hypovolemic shock, a compensatory response to maintain blood pressure. This occurs after tachycardia, as the body prioritizes increasing heart rate to compensate for volume loss. Skin changes are a later sign compared to the initial cardiovascular response of tachycardia.

Choice D reason: Decreased urine output (oliguria) occurs in hypovolemic shock when renal perfusion decreases, typically after significant volume loss. This is a later sign, as the kidneys receive reduced blood flow after compensatory mechanisms like tachycardia fail. Tachycardia appears earlier, as it is the body’s initial response to volume loss.

A. Hypernatremia B. Hyperkalemia C. Hyponatremia D. Hypokalemia

Correct Answer is A

Explanation

Choice A reason: Hypernatremia, high blood sodium (normal 135–145 mEq/L), is indicated by the 158 mEq/L level. It results from water loss, causing dehydration (dry mucous membranes, low urine output) and neurological symptoms like confusion due to brain cell shrinkage. The symptoms and lab values align with hypernatremia in this elderly client.

Choice B reason: Hyperkalemia, high potassium (normal 3.5–5.0 mEq/L), is not indicated, as the potassium level is 4.8 mEq/L, within normal range. Hyperkalemia causes arrhythmias and muscle weakness, not confusion or dehydration signs. The primary issue is high sodium, pointing to hypernatremia, not potassium imbalance.

Choice C reason: Hyponatremia, low sodium, causes swelling and neurological symptoms like seizures. The client’s sodium of 158 mEq/L indicates hypernatremia, not hyponatremia. Dry mucous membranes and low urine output suggest water loss, not sodium dilution, making hyponatremia inconsistent with the clinical and lab findings.

Choice D reason: Hypokalemia, low potassium, causes muscle weakness and arrhythmias. The client’s potassium of 4.8 mEq/L is normal, and symptoms like confusion and dehydration point to hypernatremia, not potassium deficiency. The high sodium level and clinical presentation make hypokalemia an unlikely diagnosis in this case.
