The client is admitted to the nurse’s unit with a diagnosis of heart failure. His heart is not pumping effectively, resulting in edema and coarse crackles in his lungs. The term for this condition is?

Choice A reason: Hyperchloremia, elevated chloride levels, is associated with metabolic acidosis or dehydration, not neuromuscular symptoms like wrist flexion. Chloride imbalances affect acid-base balance, not calcium-dependent muscle contractions. The inward wrist flexion suggests a neuromuscular excitability issue, which is more characteristic of low calcium levels than chloride abnormalities.

Choice B reason: Hypercalcemia, high calcium levels, causes muscle weakness, lethargy, and reduced reflexes, not increased neuromuscular excitability like wrist flexion. Calcium excess stabilizes nerve membranes, reducing spasms. The symptom described aligns with hypocalcemia, where low calcium increases nerve excitability, leading to tetany or abnormal muscle contractions.

Choice C reason: Hypocalcemia, low calcium levels, increases neuromuscular excitability due to decreased stabilization of nerve membranes. This can cause tetany, characterized by involuntary muscle contractions, such as wrist flexion (carpopedal spasm). The symptom is a classic sign of hypocalcemia, often seen in conditions like hypoparathyroidism or vitamin D deficiency.

Choice D reason: Hypomagnesemia, low magnesium, can cause neuromuscular symptoms like tremors or seizures but is less commonly associated with specific signs like wrist flexion. Magnesium affects muscle relaxation, and its deficiency typically causes generalized excitability. Hypocalcemia is more directly linked to tetany and carpopedal spasms, as seen in the client.

Choice A reason: Instructing on walker movement addresses the psychomotor domain, focusing on physical skills. This does not tackle the client’s emotional disengagement or belief of being “too old.” Without addressing motivation, technical instructions may be ineffective, as the client’s psychological barrier prevents engagement, reducing the likelihood of successful learning and adoption.

Choice B reason: Describing quality-of-life benefits targets the affective domain, addressing emotions and attitudes. By emphasizing enhanced independence, safety, and mobility, the nurse can counter the client’s defeatist mindset. This approach fosters motivation, making the client more receptive to learning walker use, as it connects the intervention to personal, meaningful outcomes.

Choice C reason: Explaining walker support for lower extremities focuses on the cognitive domain, providing technical knowledge. While informative, it does not address the client’s emotional disengagement. Without motivating the client by linking the walker to personal benefits, this approach may fail to overcome their resistance, as it lacks an emotional or motivational component.

Choice D reason: Discussing the rationale for walker use targets the cognitive domain, explaining its purpose. While this may enhance understanding, it does not address the client’s emotional barrier or lack of motivation. Without engaging the client’s feelings or highlighting personal benefits, the rationale alone is unlikely to inspire willingness to learn or use the walker.
