A nurse is caring for a client who has heart failure and a potassium level of 2.4 mEq/L. The nurse should identify which of the following medications as contributing to this lab value?

Choice A reason : Tetany and stiffness of the hands are not typical symptoms of hypothyroidism. Tetany is usually associated with hypocalcemia, which is not a direct result of hypothyroidism⁶.

Choice B reason : Exophthalmos and nervousness are symptoms associated with hyperthyroidism, not hypothyroidism. Exophthalmos, the bulging of the eyes, is particularly associated with Graves' disease, a type of hyperthyroidism⁶.

Choice C reason : Extreme fatigue and hair loss are common symptoms of hypothyroidism. The condition can lead to a slowing down of the body's metabolic processes, resulting in fatigue. Hair loss is also a frequent complaint due to the effects of reduced thyroid hormone levels on hair follicles⁶⁷⁸.

Choice D reason : Profuse sweating and flushed skin are more indicative of hyperthyroidism or other conditions, not hypothyroidism. Hypothyroidism typically leads to cold intolerance and dry skin⁶.

Choice A reason : Avoidant personality disorder is characterized by a pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Individuals with this disorder may avoid work activities or decline job offers due to fears of criticism or rejection. However, they do not typically exhibit a need for constant reassurance or an inability to make decisions, which are more indicative of dependent personality disorder⁵⁶.

Choice B reason : Borderline personality disorder involves a pattern of instability in interpersonal relationships, self-image, and affects, and marked impulsivity. While individuals with borderline personality disorder may exhibit dependency traits, they are more likely to engage in frantic efforts to avoid real or imagined abandonment and may have a pattern of unstable and intense interpersonal relationships⁷⁸.

Choice C reason : Dependent personality disorder is characterized by a pervasive and excessive need to be taken care of, leading to submissive and clinging behavior and fears of separation. Individuals with this disorder often require excessive advice and reassurance from others to make everyday decisions and may feel helpless when alone due to exaggerated fears of being unable to care for themselves. The need for constant reassurance and inability to make decisions align with the symptoms of dependent personality disorder¹²³⁴.

Choice D reason : Schizoid personality disorder is characterized by a lack of interest in social relationships, a tendency toward a solitary lifestyle, secretiveness, emotional coldness, detachment, and apathy. Individuals with schizoid personality disorder prefer to be alone and do not seek out social interactions or relationships. They do not typically display the need for reassurance or the inability to make decisions, as seen in dependent personality disorder¹²¹³¹⁴.
