Which of the following explains why children are considered a vulnerable population?
They depend on their families to provide for them financially.
They are unable to advocate for their own interests and to protect themselves from harm.
They are at risk of exposure to more diseases due to constant interaction with other children.
They are at risk of serious illness due to the re-emergence of diseases previously eradicated, but are now on the rise because of the anti-vaccination movement.
The Correct Answer is B
Choice A reason: Financial dependence is a characteristic of childhood but does not fully explain their vulnerability in healthcare or research contexts. Vulnerability is more about autonomy and protection.
Choice B reason: Children are considered vulnerable because they lack the cognitive and legal capacity to make informed decisions, advocate for themselves, or recognize and avoid harm. This necessitates special protections in clinical, legal, and research settings.
Choice C reason: While children may be exposed to communicable diseases due to social interaction, this is a public health concern rather than a defining feature of vulnerability.
Choice D reason: The anti-vaccination movement poses risks, but vulnerability is not defined by epidemiological trends. It is rooted in developmental and legal incapacity to self-protect.

Correct Answer is C
Explanation
Choice A reason: Cannabis dependence was a term used in earlier diagnostic frameworks such as DSM-IV. It has since been replaced by the broader and more clinically accurate term “cannabis use disorder” in DSM-5, which encompasses both abuse and dependence.
Choice B reason: Cannabis abuse disorder is also an outdated term from DSM-IV. DSM-5 integrates abuse and dependence into a single diagnosis—cannabis use disorder—based on severity and symptom criteria.
Choice C reason: Cannabis use disorder is the correct DSM-5 diagnosis. It includes patterns of problematic use leading to significant impairment or distress, such as continued use despite interpersonal problems, legal issues, and risky behaviors like driving under the influence. The patient’s daily use, denial of the problem, and conflict with his spouse meet criteria for this diagnosis.
Choice D reason: Unspecified cannabis-related disorder is used when symptoms are present but do not meet full criteria for a specific diagnosis. In this case, the patient clearly meets criteria for cannabis use disorder, making this option inappropriate.
Correct Answer is B
Explanation
Choice A reason: Sublimation is a mature defense mechanism where unacceptable impulses are transformed into socially acceptable actions or behaviors. For example, someone might channel aggressive impulses into competitive sports. This does not apply to the scenario, as the man is not redirecting his behavior into a constructive outlet but rather continuing harmful behavior.
Choice B reason: Denial is a primitive defense mechanism where a person refuses to accept reality or facts. In the context of substance use, denial is common among individuals with alcohol use disorder. The man’s repeated arrests and continued drinking, coupled with his insistence that he has no problem, exemplify denial. He is rejecting the reality of his condition and its consequences, which is a hallmark of this defense mechanism.
Choice C reason: Reaction formation involves behaving in a way that is opposite to one's true feelings or desires. For example, someone who feels hostility might act overly friendly. This does not fit the scenario, as the man is not displaying behavior contrary to his internal state—he is simply refusing to acknowledge the problem.
Choice D reason: Repression is an unconscious process where distressing thoughts or memories are pushed out of conscious awareness. While repression may play a role in substance use disorders, the man’s overt behavior and verbal denial suggest a conscious refusal to accept reality, which aligns more closely with denial than repression.
