Erik is a 26-year-old patient who abuses heroin. He states to you, "I’ve been using more heroin lately. I told my counselor about it and she said I need more and more heroin to feel the effect I want." Which of the following does this describe?
Tolerance
Intoxication
Withdrawal
Addiction
The Correct Answer is A
Choice A reason: Tolerance is a physiological state in which repeated exposure to a substance results in a diminished response, requiring increasingly larger doses of the drug to achieve the same initial effect or desired "high." This occurs due to neuroadaptation at the cellular and receptor levels within the central nervous system.
Choice B reason: Intoxication refers to the acute state of being under the influence of a substance, resulting in maladaptive behavioral or psychological changes. While Erik is a user, the statement specifically addresses the need for increased quantity over time rather than the immediate physiological effects of a single dose of heroin.
Choice C reason: Withdrawal consists of the specific physical and psychological symptoms that occur when a person stops or reduces the intake of a substance they are dependent upon. Erik is describing the process of increasing his usage to maintain effect, rather than the symptoms of distress following the cessation of the drug.
Choice D reason: Addiction, or substance use disorder, is a broad clinical diagnosis encompassing compulsive drug seeking, loss of control, and continued use despite negative consequences. While tolerance is a common physiological component of addiction, Erik's specific description of needing more drug for the same effect is the precise definition of tolerance.

Correct Answer is A
Explanation
Choice A reason: Primary prevention in mental health focuses on reducing the incidence of disorders or crises by promoting mental health and providing education before a crisis occurs. Teaching a community about resources equips them with the knowledge to intervene early, potentially preventing a stressful situation from escalating into a full-blown psychiatric emergency.
Choice B reason: Implementing suicide precautions is a form of secondary prevention. This intervention occurs when an acute problem (suicidal ideation) has already been identified. The goal here is to prevent the immediate completion of the act and ensure the safety of a patient who is already in a state of crisis.
Choice C reason: Assessing coping strategies after a suicide attempt is part of tertiary prevention. At this stage, the crisis has already occurred, and the patient has suffered harm. The nursing focus is on rehabilitation, recovery, and preventing further occurrences by analyzing the failures in previous coping mechanisms to improve future resilience.
Choice D reason: Referring a patient to a partial hospitalization program is a tertiary intervention. It is aimed at patients with chronic or severe mental illness (like schizophrenia) to provide a high level of support and prevent total disability or institutionalization. It does not fall under the umbrella of primary crisis prevention.
Correct Answer is D
Explanation
Choice A reason: Euphoria is defined as a state of intense happiness, excitement, or overconfidence, often seen in the manic phase of bipolar disorder. This is the exact opposite of the patient's report, which describes a complete lack of pleasure and a pervasive sense of unhappiness.
Choice B reason: Dysthymia, now known as Persistent Depressive Disorder, is a chronic clinical diagnosis characterized by a depressed mood for at least 2 years. While the patient’s symptoms align with this, the term describes the whole disorder rather than the specific symptom of losing interest in pleasure.
Choice C reason: Anergia refers to a lack of energy or physical passivity. While often co-occurring with depression, the patient's statement specifically targets the loss of joy and interest in previously enjoyed activities (holidays), which is a psychological and emotional symptom rather than a physical energy deficit.
Choice D reason: Anhedonia is the clinical term for the inability to experience pleasure from activities that were previously found enjoyable. The patient’s description of holidays losing their meaning and the absence of happiness is a textbook clinical presentation of this specific symptom commonly found in major depressive disorder.
