Choice A reason: Have you had a recent influenza infection?

Guillain-Barré syndrome (GBS) is often preceded by an infection, most commonly respiratory or gastrointestinal infections. Influenza is a significant respiratory infection that can trigger GBS. Asking about recent influenza infection helps in identifying a potential cause of the syndrome. According to the Mayo Clinic, many cases of GBS occur after a respiratory or gastrointestinal infection1. Therefore, this question is crucial in the assessment of a client with suspected GBS.

Choice B reason: Have you traveled overseas recently?

While travel history can be relevant in diagnosing various conditions, it is less directly related to Guillain-Barré syndrome. GBS is not typically associated with travel but rather with infections that can occur anywhere. Therefore, this question is less pertinent compared to asking about recent infections.

Choice C reason: Do you have a history of chronic alcohol abuse?

Chronic alcohol abuse can lead to various neurological conditions, but it is not specifically linked to Guillain-Barré syndrome. GBS is an acute condition often triggered by an infection, not by chronic alcohol use. Thus, while this question might be relevant in a broader neurological assessment, it is not directly related to GBS.

Choice D reason: Are you taking a multivitamin?

The use of multivitamins is generally not related to the development of Guillain-Barré syndrome. This question does not help in identifying the cause or confirming the diagnosis of GBS. It is more relevant to a general health assessment rather than a specific inquiry for GBS.

Choice A: Potassium Level

Reason: Monitoring potassium levels is crucial in clients with bulimia nervosa due to the risk of hypokalemia (low potassium levels), which can result from frequent vomiting and laxative abuse. Hypokalemia can lead to serious complications, including cardiac arrhythmias. In this case, the client’s potassium level improved from 3.2 mEq/L (below the normal range of 3.5 to 5 mEq/L) on June 1 to 3.7 mEq/L (within the normal range) on June 15. This improvement indicates a positive response to treatment, as it suggests that the client is experiencing fewer episodes of vomiting or laxative abuse, leading to better electrolyte balance.

Choice B: ECG Report

Reason: While the ECG report is important for assessing cardiac health, it is not a direct indicator of therapeutic response to bulimia nervosa treatment. The presence of premature ventricular contractions (PVCs) on the ECG can be related to electrolyte imbalances, particularly hypokalemia. However, the ECG itself does not provide information about the client’s behaviors or coping mechanisms, which are more directly related to the treatment of bulimia

nervosa. Therefore, while the ECG report is useful for monitoring cardiac health, it is not one of the primary indicators of therapeutic response in this context.

Choice C: BUN Level

Reason: Blood Urea Nitrogen (BUN) levels can indicate kidney function and hydration status. Elevated BUN levels, as seen in this client (28 mg/dL on June 1 and 26 mg/dL on June 15, with a normal range of 10 to 20 mg/dL), may suggest dehydration or impaired kidney function. However, BUN levels are not specific indicators of therapeutic

response to bulimia nervosa treatment. They do not directly reflect changes in the client’s eating behaviors, purging habits, or coping skills. Therefore, while monitoring BUN levels is important for overall health, it is not a primary indicator of therapeutic response in this case.

Choice D: Laxative Usage

Reason: Reducing or eliminating laxative usage is a significant indicator of therapeutic response in clients with bulimia nervosa. Laxative abuse is a common purging behavior in bulimia nervosa, and its reduction indicates progress in treatment. The client’s report of laxative usage provides direct insight into their purging behaviors. A

decrease in laxative use suggests that the client is gaining better control over their eating disorder and is adhering to the treatment plan. This behavioral change is a critical component of recovery and indicates a positive therapeutic response.

Choice E: Overeating Cycle/Purging

Reason: Assessing changes in the client’s overeating and purging cycle is essential for evaluating therapeutic response. Bulimia nervosa is characterized by cycles of binge eating followed by purging behaviors such as vomiting or laxative abuse. A reduction in the frequency or severity of these cycles indicates that the client is responding well to treatment. The client’s self-reported behaviors regarding overeating and purging provide valuable information about their progress. A decrease in these behaviors suggests that the client is developing healthier eating patterns and coping mechanisms, which are key goals of treatment.

Choice F: Coping Skills

Reason: Developing effective coping skills is a crucial aspect of treatment for bulimia nervosa. Clients often use disordered eating behaviors as a way to cope with emotional distress. By learning and implementing healthier coping strategies, clients can reduce their reliance on harmful behaviors such as binge eating and purging. Assessing the client’s coping skills involves evaluating their ability to manage stress, emotions, and triggers in a healthy manner. Improvement in coping skills indicates that the client is making progress in their recovery and is better equipped to handle challenges without resorting to disordered eating behaviors.
