addiction - Nursing Case Study
Pathophysiology
• Primary mechanism: Addiction primarily involves the brain's reward system, particularly the mesolimbic pathway. Substances increase dopamine release in this area, reinforcing behaviors and creating a cycle of craving and seeking.
• Secondary mechanism: Neuroadaptation occurs with repeated substance use, where the brain adjusts to the excess dopamine by reducing receptor sensitivity or number, leading to tolerance and withdrawal symptoms when not using the substance.
• Key complication: These changes can lead to impaired decision-making and increased compulsivity, as the prefrontal cortex, responsible for self-control and judgment, is affected, making it difficult for individuals to resist the urge to use despite negative consequences.

Section 1
Following the initial assessment, the healthcare team decided to conduct a series of diagnostic tests to gain a clearer understanding of the patient's condition. Blood tests revealed elevated liver enzymes, suggesting early signs of liver stress potentially due to excessive alcohol consumption. A urine drug screen confirmed the presence of alcohol and benzodiazepines, which the patient had not disclosed using. These findings indicated that the patient might be self-medicating his anxiety symptoms with substances beyond what was prescribed, complicating his hypertension management. Additionally, an ECG was performed due to the patient's elevated heart rate and hypertension, which showed sinus tachycardia but no other immediate cardiac concerns.
The patient's mental health assessment highlighted significant anxiety and reported feelings of helplessness and low motivation, contributing to his substance use. The psychiatric evaluation suggested a potential adjustment of his current sertraline dosage or the introduction of adjunctive therapy to better manage his anxiety symptoms. His insomnia and restlessness were attributed both to his substance use and inadequate anxiety control, indicating a need for a comprehensive treatment strategy.
These diagnostic results emphasize the need for a multidisciplinary approach to address the intertwined physical and mental health challenges. The healthcare team considered initiating a medically supervised detoxification program to address both alcohol and benzodiazepine use. The patient's hypertension was also a concern, necessitating close monitoring and potential medication adjustments. This plan aimed to stabilize the patient's physical condition while simultaneously beginning to address his psychological and behavioral health needs, setting the stage for more intensive addiction treatment and lifestyle modifications.

Response to Interventions:
After initiating the medically supervised detoxification program, the patient began to show some initial signs of progress. His blood pressure, which had been persistently elevated, started to show a gradual decrease, with recent readings averaging around 138/85 mmHg. However, despite these improvements, the patient continued to experience episodes of tachycardia, with heart rates occasionally spiking to 110-120 beats per minute, particularly during moments of increased anxiety. The healthcare team adjusted his hypertension management by introducing a low-dose beta-blocker, which aimed not only to control his blood pressure but also to provide some relief from the tachycardia and anxiety symptoms.
Despite the positive trajectory in managing the patient's physical symptoms, his mental health status presented new challenges. The adjustment in his sertraline dosage showed some promise, as the patient reported a slight reduction in feelings of helplessness. However, his insomnia persisted, and his restlessness seemed to intensify during the detoxification process. The psychiatric team, recognizing the potential withdrawal effects, introduced a non-benzodiazepine sleep aid to help regulate his sleep patterns. They also scheduled more frequent counseling sessions to offer psychological support and to help the patient develop healthy coping mechanisms for his anxiety.
These developments highlighted the complexity of the patient's condition, necessitating ongoing adjustments and close monitoring. The multidisciplinary team remained vigilant, focusing on the delicate balance between managing withdrawal symptoms, stabilizing his cardiovascular status, and addressing his mental health needs. As the patient progressed through the detoxification program, the team prepared to transition him into more intensive addiction therapy, aiming to build upon the foundation of initial stabilization and set the stage for sustainable recovery.

As the patient continued through the detoxification program, a new complication emerged that required the healthcare team's immediate attention. During a routine assessment, the nurse noted that the patient was experiencing increased episodes of dizziness and lightheadedness, particularly when transitioning from lying to standing. Further evaluation revealed that the patient's blood pressure was dropping significantly during positional changes, with orthostatic hypotension evident as readings fell to 100/65 mmHg upon standing. This raised concerns about the current management strategy, particularly the beta-blocker dosage, which might be contributing to these symptoms.
In response to these findings, the team promptly reviewed the patient's medication regimen. They decided to adjust the beta-blocker dosage to mitigate the risk of exacerbating the patient's orthostatic changes while still aiming to control his heart rate and anxiety. Concurrently, the team emphasized the importance of non-pharmacological interventions to manage dizziness, such as encouraging the patient to rise slowly and ensuring adequate hydration. Regular monitoring of orthostatic vital signs was implemented to evaluate the effectiveness of these interventions and to detect any further complications early.
As the healthcare team navigated these challenges, they remained focused on the patient's holistic care. Recognizing the potential impact of these physical complications on the patient’s mental health, the psychiatric team intensified their efforts to support the patient through counseling and reassurance. These adjustments aimed to foster a stable environment that would facilitate continued progress in the detoxification process and prepare the patient for the next phase of intensive addiction therapy. The team acknowledged the complexity of the case and remained committed to adapting their approach to meet the evolving needs of the patient.
Section 4
As the detoxification program progressed, the healthcare team closely monitored the patient's response to the adjusted beta-blocker dosage and implemented non-pharmacological strategies. Over the next few days, the patient reported a reduction in dizziness when standing, which suggested that the interventions were beginning to stabilize his orthostatic hypotension. However, during a later assessment, the nurse noticed that the patient's heart rate had increased to 102 beats per minute, a notable change from the previous 78 beats per minute, indicating potential rebound tachycardia following the beta-blocker adjustment. Additionally, the patient expressed feeling more anxious and restless, which prompted further evaluation of his overall condition.
In response to these new signs, the healthcare team conducted a thorough review of the patient's current clinical status. Laboratory tests revealed a mild electrolyte imbalance, with sodium levels at 130 mEq/L and potassium at 3.3 mEq/L, likely contributing to the patient's symptoms. The team hypothesized that these imbalances were due to increased diuresis and inadequate oral intake, compounded by the patient's ongoing detoxification process. To address this, they initiated a tailored electrolyte replacement plan and encouraged the patient to increase his fluid and nutritional intake, emphasizing foods rich in potassium.
While these interventions were underway, the psychiatric team continued to support the patient through counseling sessions aimed at managing his anxiety. The team recognized the interplay between physical symptoms and mental well-being, particularly in the context of addiction recovery. By maintaining an integrated approach, they aimed to create a supportive environment that would not only address immediate physiological concerns but also foster emotional resilience as the patient prepared for the subsequent phases of addiction therapy. The team remained vigilant, aware that the patient's journey through detoxification and recovery might present further challenges requiring continued adaptation and collaboration.
Section 5
As the healthcare team continued to monitor the patient's progress, they observed a change in his respiratory status. During a routine assessment, the nurse noted that the patient's respiratory rate had increased to 24 breaths per minute, accompanied by mild wheezing and a persistent cough. These symptoms were unexpected, given the previous stability achieved in his cardiovascular parameters. Concerned about the potential for respiratory complications, the team conducted a more detailed respiratory examination, which revealed diminished breath sounds in the lower lobes bilaterally.
Further diagnostic workup, including a chest X-ray, indicated the presence of mild pulmonary congestion. The team speculated that the fluid accumulation might be a consequence of the recent electrolyte imbalances and the body's compensatory mechanisms during detoxification. Given these findings, they decided to adjust the patient's fluid management plan to prevent additional fluid overload and reduce the risk of developing more severe pulmonary complications. They also initiated breathing exercises and positioned the patient to optimize lung expansion and airflow.
In response to these interventions, the patient's respiratory symptoms began to improve, and his oxygen saturation levels stabilized at 96% on room air. The team continued to emphasize the importance of adhering to the electrolyte replacement and nutritional plan, recognizing that these measures were crucial in preventing further episodes of instability. This integrated approach not only addressed the immediate respiratory concerns but also reinforced the importance of holistic care in the management of complex cases such as addiction recovery. As the patient progressed, the team remained attentive to the delicate balance required in managing his multifaceted health needs, preparing for potential new challenges in his ongoing recovery journey.
