1. Which of the following statements about the DSM-5 is inaccurate?

• A. It includes specific criteria for diagnosing mental disorders.
• B. It is used by mental health professionals to guide diagnosis.
• C. It provides a classification system for mental disorders.
• D. It includes guidelines for the treatment of mental disorders.

Correct answer: D

Rationale: The DSM-5 is a diagnostic tool that provides specific criteria for diagnosing mental disorders, is utilized by mental health professionals to guide diagnosis, and offers a systematic classification of mental disorders. The statement that the DSM-5 includes guidelines for the treatment of mental disorders is inaccurate. The primary focus of the DSM-5 is on diagnosis and classification, not treatment. Therefore, choice D is the correct answer. Choices A, B, and C accurately describe the purpose and functions of the DSM-5.

2. 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.

3. A client has been diagnosed with depersonalization/derealization disorder. Which of the following behaviors should the nurse expect?

• A. Feelings of detachment from one's body
• B. Fear of gaining weight
• C. Paralysis of a limb
• D. Episodes of hypomania

Correct answer: A

Rationale: Depersonalization/derealization disorder is characterized by feelings of detachment from one's body or surroundings. Individuals with this disorder may feel like they are observing themselves from outside their body or that the world around them is unreal. Therefore, the nurse should expect behaviors such as feelings of detachment from one's body (A). Fear of gaining weight (B) is more indicative of an eating disorder, paralysis of a limb (C) could be related to neurological issues, and episodes of hypomania (D) are associated with mood disorders like bipolar disorder, but not specifically with depersonalization/derealization disorder.

4. When assessing a client diagnosed with anorexia nervosa, which of the following findings should the nurse expect? Select one that does not apply.

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

Correct answer: D

Rationale: In a client diagnosed with anorexia nervosa, expected findings include amenorrhea, lanugo, hypotension, and bradycardia. Hyperkalemia is not typically associated with anorexia nervosa; instead, hypokalemia, which is low potassium levels, is more common. Hypokalemia can result from decreased intake of potassium-rich foods or excessive purging behaviors commonly seen in individuals with anorexia nervosa.

5. A healthcare professional is assessing a client with major depressive disorder. Which of the following findings should the professional expect? Select one that does not apply.

• A. Anhedonia
• B. Hypersomnia
• C. Fatigue
• D. Flight of ideas

Correct answer: D

Rationale: In major depressive disorder, common findings include anhedonia (loss of interest or pleasure), hypersomnia (excessive sleepiness), fatigue, and feelings of worthlessness. Flight of ideas, characterized by racing thoughts and rapid speech, is more commonly associated with bipolar disorder, particularly during manic episodes. Therefore, 'Flight of ideas' does not apply to the expected findings in major depressive disorder.
