A doctor prescribes diazepam IV at a dose of 7.5 mg to a patient. The available diazepam solution is 5 mg/mL. How many mL should the nurse prepare for administration?

Choice A reason: Panic disorder is characterized by recurrent, unexpected panic attacks, which are sudden surges of intense fear or discomfort. It is not defined by a "variety of circumstances" or constant worry, but rather by the acute physiological "fight or flight" response and the subsequent fear of future attacks.

Choice B reason: Generalized anxiety disorder (GAD) is defined by the DSM-5 as excessive anxiety and worry about a number of events or activities (such as work or school performance) for at least 6 months. The client’s inability to control this pervasive worry is the hallmark feature of GAD.

Choice C reason: Separation anxiety disorder involves excessive fear or anxiety concerning separation from those to whom the individual is attached. While it involves worry, the worry is specific to the loss of or harm to attachment figures, rather than a broad spectrum of various life circumstances.

Choice D reason: Agoraphobia is a disorder where an individual fears or avoids places or situations that might cause them to feel trapped, helpless, or embarrassed. This is a situational anxiety related to the environment and safety, not the generalized, free-floating worry that permeates different aspects of daily life.

Choice A reason: Arbitrarily limiting medical visits to twice a year is often unrealistic and can increase the client's anxiety levels. If a genuine medical issue arises, the client may feel prevented from seeking necessary care. Effective management involves regular, brief, scheduled appointments rather than strict annual limits that ignore the client's perceived distress.

Choice B reason: While lifestyle modifications like diet and exercise are beneficial for overall health, suggesting they replace medical consultations dismisses the client's psychological disorder. Clients with illness anxiety disorder have a preoccupation with having a serious illness; telling them to stop seeing doctors can damage the therapeutic alliance and worsen their somatic fears.

Choice C reason: Directly advising the client that their behavior is counterproductive can be perceived as dismissive or judgmental. This approach often leads to "doctor shopping" as the client seeks a provider who validates their concerns. Professional management requires a more supportive, structured framework rather than a verbal reprimand regarding their help-seeking behaviors.

Choice D reason: Prioritizing a single primary healthcare provider is the gold standard for treating illness anxiety disorder. A consistent relationship prevents unnecessary diagnostic testing, conflicting medical advice, and polypharmacy. It allows the provider to distinguish between somatic preoccupations and new, significant physical changes while providing a secure base for the client's ongoing psychological support.
