1. Which neurotransmitter is primarily implicated in the development of schizophrenia?

• A. Serotonin
• B. Norepinephrine
• C. Dopamine
• D. Acetylcholine

Correct answer: C

Rationale: The correct answer is dopamine. Dopamine dysregulation is a key factor in the development of schizophrenia. Excess dopamine activity in certain brain regions is associated with positive symptoms of schizophrenia, such as hallucinations and delusions. Dopaminergic medications that reduce dopamine levels are often used to manage these symptoms, further supporting the role of dopamine in schizophrenia. Serotonin (Choice A) is more commonly associated with mood regulation and is implicated in depression and anxiety disorders. Norepinephrine (Choice B) is involved in the body's 'fight or flight' response and is linked to conditions like anxiety and PTSD. Acetylcholine (Choice D) plays a role in muscle movement and memory but is not primarily implicated in schizophrenia.

2. During an assessment of a client with suspected substance use disorder, which of the following findings should the nurse expect? Select one that doesn't apply.

• A. Feelings of hopelessness
• B. Increased tolerance to the substance
• C. Withdrawal symptoms when not using the substance
• D. Unsuccessful attempts to cut down or control use

Correct answer: A

Rationale: In clients with substance use disorder, common findings include increased tolerance to the substance, withdrawal symptoms when not using it, and unsuccessful attempts to cut down or control use. Feelings of hopelessness are not typically a direct manifestation of substance use disorder. Instead, feelings of hopelessness may be associated with other mental health conditions or situational factors. Therefore, the correct answer is A. Choices B, C, and D are all expected findings in clients with substance use disorder.

3. A patient with schizophrenia is prescribed risperidone. The nurse should monitor the patient for which common side effect of this medication?

• A. Agranulocytosis
• B. Weight gain
• C. Hair loss
• D. Hyperthyroidism

Correct answer: B

Rationale: When a patient is prescribed risperidone, an atypical antipsychotic, the nurse should monitor for weight gain as it is a common side effect of this medication. Weight gain can occur due to metabolic changes and increased appetite associated with risperidone use. Agranulocytosis is a severe decrease in a type of white blood cells, and it is not a common side effect of risperidone. Hair loss and hyperthyroidism are also not typically associated with risperidone use.

4. A student finds that they come down with a sinus infection toward the end of every semester. When this occurs, which stage of stress is the student most likely experiencing?

• A. Alarm reaction stage
• B. Stage of resistance
• C. Stage of exhaustion
• D. Fight-or-flight stage

Correct answer: C

Rationale: The student is most likely experiencing the stage of exhaustion. In this stage, the body's exposure to stress has been prolonged, and adaptive energy has been depleted. As a result, diseases of adaptation, such as the recurrent sinus infection in this case, are more likely to occur. The alarm reaction stage is the initial stage of the stress response, where the body perceives a threat and activates the fight-or-flight response. The stage of resistance is when the body tries to adapt and cope with the stressor. The fight-or-flight response is the immediate reaction to a perceived threat, involving physiological changes to prepare the body to either fight the stressor or flee from it.

5. A healthcare professional is assessing a client diagnosed with anorexia nervosa. Which of the following findings shouldn't the professional expect?

• A. Amenorrhea
• B. Lanugo
• C. Hypotension
• D. Hyperkalemia

Correct answer: D

Rationale: When assessing a client diagnosed with anorexia nervosa, healthcare professionals should expect findings such as amenorrhea, lanugo, hypotension, and bradycardia. Hyperkalemia is not typically associated with anorexia nervosa; instead, hypokalemia, which is low potassium levels, is more commonly seen in these individuals due to malnutrition and other factors.
