Correct Answer: C

Rationale: The correct answer is C: Auditory expiratory wheezing. Expiratory wheezing is a common sign of reactive airway disease, such as asthma, where airways are constricted, making it difficult to expel air from the lungs. Choices A, B, and D are incorrect as they are not typically associated with reactive airway disease. Auditory gurgling may suggest airway secretions or fluid accumulation, inspiratory laryngeal stridor indicates upper airway obstruction, and frequent dry coughing is more commonly seen in conditions like upper respiratory infections or postnasal drip.

Correct Answer: B

Rationale: The correct answer is B: 'Sense of impending doom.' In panic disorder, a sense of impending doom is a hallmark symptom often experienced by clients. This intense feeling of dread or fear is a key feature of panic attacks. Compulsive behavior (choice A) may be more indicative of obsessive-compulsive disorder rather than panic disorder. Fear of flying (choice C) may be more related to specific phobias rather than panic disorder. Predictable episodes (choice D) do not align with the unpredictable nature of panic attacks.

Correct Answer: D

Rationale: Feelings of alienation or isolation are common triggers for suicidal behavior in adolescents. This sense of being disconnected or isolated from others can lead to despair and hopelessness, increasing the risk of suicidal ideation. Choices A, B, and C are less commonly associated with suicide in adolescents. Progressive failure to adapt may contribute to stress, but it is not typically the primary cause of suicide. Feelings of anger or hostility, while negative emotions, do not always lead to suicidal behavior in adolescents. Reunion wish or fantasy is not a recognized primary cause of suicide in this age group.

Correct Answer: A

Rationale: Vertical transmission is the transfer of a disease-causing agent (pathogen) from mother to baby during the period immediately before and after birth. This process can lead to the baby acquiring infections or diseases from the mother. Choice A is correct because it accurately describes vertical transmission. Choices B, C, and D are incorrect as they do not reflect the definition of vertical transmission.

Correct Answer: A

Rationale: Corrected Rationale: Chronic lead poisoning can lead to severe and irreversible damage to the central nervous system, including cognitive and developmental delays. Central nervous system damage is the most serious effect of chronic lead poisoning because it can have long-lasting consequences on a child's cognitive function and overall development. Moderate anemia (Choice B), renal tubule damage (Choice C), and growth impairment (Choice D) can also occur due to lead poisoning, but they are not as severe or potentially irreversible as the damage to the central nervous system.
