A nurse is preparing to administer amantadine 150 mg PO every 12 hr. The available medication is amantadine 50 mg/5 mL syrup.

How many mL should the nurse administer per dose?

The nurse should administer 2 tablets per dose.

Rationale:

Step 1: Determine the desired dose of diphenhydramine. The desired dose is 50 mg.

Step 2: Determine the available tablet strength. The available tablet strength is 25 mg.

Step 3: Divide the desired dose by the tablet strength to determine the number of tablets needed. 50 mg / 25 mg/tablet = 2 tablets

Therefore, the nurse should administer 2 tablets of diphenhydramine 25 mg per dose to achieve the desired dose of 50 mg.

Choice A rationale:

Personality disorders are not typically considered to be comorbidities of eating disorders. While some personality traits, such as perfectionism and obsessiveness, may be more common in individuals with eating disorders, these traits do not necessarily

constitute a personality disorder. Additionally, the presence of a personality disorder does not typically increase the risk of developing an eating disorder.

Choice B rationale:

Depression is one of the most common comorbidities associated with eating disorders. Studies have shown that up to 50% of individuals with eating disorders also experience depression. The relationship between eating disorders and depression is complex and bidirectional. Depression can contribute to the development of an eating disorder, and the behaviors associated with eating disorders can also worsen depression.

Choice C rationale:

Breathing-related sleep disorders, such as obstructive sleep apnea, are not typically associated with eating disorders. While some individuals with eating disorders may experience sleep disturbances, these disturbances are more likely to be related to other factors, such as anxiety or depression.

Choice D rationale:

Obsessive-compulsive disorder (OCD) is another common comorbidity of eating disorders. Studies have shown that up to 30% of individuals with eating disorders also have OCD. The symptoms of OCD, such as obsessive thoughts and compulsive behaviors, can overlap with the symptoms of eating disorders. For example, an individual with OCD may have obsessive thoughts about food and weight, and they may engage in compulsive behaviors related to eating, such as calorie counting or food restriction.

Choice E rationale:

Schizophrenia is not typically associated with eating disorders. While some individuals with schizophrenia may experience disturbances in eating behavior, these disturbances are more likely to be related to other symptoms of the disorder, such as delusions or hallucinations.

Choice F rationale:

Anxiety is another common comorbidity of eating disorders. Studies have shown that up to 60% of individuals with eating disorders also experience anxiety disorders. Anxiety can contribute to the development of an eating disorder, and the behaviors associated with eating disorders can also worsen anxiety.
