A 35-year-old female has been diagnosed with moderate depression with sleep problems. The psychiatrist decides to start her on mirtazapine as it would also help her with the sleep. Which of the following is responsible for mirtazapine's action as an hypnotic?

Correct Answer: A

Rationale: The correct answer is A) H1 receptor blocking. Mirtazapine's action as a hypnotic is primarily due to its histamine (H1) receptor blocking properties. By antagonizing the H1 receptors, mirtazapine promotes sedation and improves sleep quality. This is particularly beneficial for individuals with depression who also experience sleep disturbances. Option B) 5HT1A blocking is incorrect because mirtazapine actually acts as a 5HT1A receptor agonist, which contributes to its antidepressant effects rather than its hypnotic properties. Option C) 5HT2C blocking is incorrect because mirtazapine's action on the 5HT2C receptor is also associated with its antidepressant effects and appetite stimulation, rather than its hypnotic properties. Option D) 5HT2A blocking is incorrect as mirtazapine's antagonism of the 5HT2A receptor is linked to its antidepressant and anxiolytic effects, not its hypnotic action. Educationally, understanding the pharmacological mechanisms of medications used in treating psychobiologic disorders is crucial for nurses and healthcare professionals to provide safe and effective care to patients. Knowing how mirtazapine works as a hypnotic can help healthcare providers monitor and manage its effects on patients with depression and sleep disturbances.

Correct Answer: B

Rationale: The correct answer is B) Play, which corresponds to Vygotsky's stage of development in Early Childhood (2-7 years). In this stage, children engage in pretend play, which is crucial for their cognitive and social development. Through play, children learn to solve problems, negotiate with others, and develop their imagination. This stage is characterized by the development of symbolic thought and language. A) Sensorimotor is a stage in Piaget's theory of cognitive development, not Vygotsky's. It occurs in infancy (0-2 years) and focuses on the coordination of sensory experiences with motor actions. C) Oedipal stage is a psychoanalytic concept proposed by Freud, not Vygotsky. It pertains to the psychosexual development of children between 3-6 years old. D) Preoperational stage is also from Piaget's theory and occurs in early childhood (2-7 years). It is characterized by egocentrism, animism, and lack of conservation. Understanding Vygotsky's theory of sociocultural development is essential for educators as it emphasizes the role of social interactions, culture, and language in cognitive development. By recognizing the significance of play in early childhood, educators can create enriched learning environments that promote children's cognitive growth and social skills.

Correct Answer: D

Rationale: Erotomanic delusions involve a false belief that another person, often someone famous or of higher status, is in love with the individual, which fits Bob's scenario. Grandiose delusions (A) involve exaggerated self-importance, jealous delusions (B) involve infidelity suspicions, and OCD (C) involves intrusive thoughts and compulsions, not delusions, making D correct.

Correct Answer: A

Rationale: In this scenario, the correct answer is A) dependent personality. A person who has an extreme lack of self-confidence and allows others to make decisions for them fits the criteria for a dependent personality. This individual relies heavily on others for emotional and physical needs, lacks self-assurance, and has difficulty making decisions independently. Option B) narcissistic personality is incorrect because narcissistic individuals typically exhibit grandiosity, a need for admiration, and a lack of empathy towards others. This contrasts with the described individual's lack of self-confidence and reliance on others. Option C) paranoid personality is incorrect as individuals with this disorder display distrust and suspicion of others, often interpreting benign actions as malevolent. This does not align with the described individual's behavior of allowing others to control their life due to lack of self-confidence. Option D) antisocial personality is also an incorrect choice. Individuals with antisocial personality disorder typically exhibit a disregard for the rights of others, deceitfulness, impulsivity, and a lack of remorse for their actions. This differs from the described individual's passive and submissive behavior. Educationally, understanding different personality disorders is crucial in the field of psychology and healthcare. Recognizing the characteristics of each disorder aids in accurate diagnosis, appropriate treatment planning, and effective patient care. By grasping the distinctions between personality disorders, healthcare professionals can provide tailored support and interventions to individuals based on their unique needs and behaviors.

Correct Answer: C

Rationale: The correct answer is C) sexual disorders. Paraphilias are characterized by intense sexual urges, fantasies, or behaviors involving non-human objects, the suffering or humiliation of oneself or one's partner, or children or other non-consenting persons. These are considered sexual disorders because they involve atypical or deviant sexual interests that may cause distress or impairment in functioning. Option A) somatoform disorders involve physical symptoms that cannot be explained by a medical condition and are not intentionally produced. Paraphilias do not fall under this category. Option B) generalized anxiety is characterized by excessive and uncontrollable worry about a variety of events or activities. Paraphilias do not relate to anxiety disorders. Option D) personality disorders involve patterns of behavior, emotions, and thoughts that are inflexible and maladaptive. While individuals with paraphilias may have underlying personality issues, paraphilias themselves are distinct from personality disorders. In an educational context, understanding the categorization of paraphilias helps healthcare professionals appropriately assess, diagnose, and provide treatment for individuals experiencing these disorders. It is essential for nurses and other healthcare providers to have a comprehensive understanding of psychobiologic disorders like paraphilias to offer quality care and support to patients.
