Question 1 of 5
A 16-year-old boy... decreasing performance in school... more irritable and irresponsible... Which of the following disorders is the most likely cause?
Correct Answer: E
Rationale: Substance use explains irritability, irresponsibility, and declining grades with a friend group change, common in adolescence. Bipolar (A) and depression (C) may affect mood but lack social shift specificity. Conduct (B) involves aggression, not necessarily grades.
Question 2 of 5
Following immunization, an anaphylactic response would usually occur within:
Correct Answer: C
Rationale: Anaphylaxis is a rapid-onset allergic reaction, typically occurring within 5-30 minutes after vaccination, though it can rarely extend to an hour. This is due to the immediate release of mediators like histamine following IgE-mediated hypersensitivity. Choice A (12-24 hours) and D (2-4 hours) are far too delayed for anaphylaxis, which is an acute emergency. Choice B (60-90 minutes) may capture some late-onset cases but exceeds the usual timeframe for most reactions.
Question 3 of 5
The temperature of vaccine refrigerators must be checked and logged:
Correct Answer: B
Rationale: CDC guidelines mandate that vaccine refrigerator temperatures be checked and logged twice daily (morning and evening) to ensure they remain within 2°C-8°C. This frequent monitoring detects excursions promptly, preventing vaccine spoilage. Choice A (once a week) and D (twice a week) are insufficient, and Choice C (once daily) misses potential overnight fluctuations, making Choice B the standard practice.
Question 4 of 5
Informed consent must be validated as per the:
Correct Answer: B
Rationale: Informed consent is a fundamental patient right, often enshrined in documents like the U.S. Patients’ Bill of Rights (Choice B), which outlines autonomy, information disclosure, and decision-making capacity. Choice A (Minister of Health) and C (Chief Medical Officer) are roles, not legal frameworks, and Choice D (Public Health Act) may govern public health measures but not specifically validate consent processes, which are rooted in patient rights.
Question 5 of 5
Foreign substances capable of causing disease are called:
Correct Answer: B
Rationale: Antigens are foreign substances (e.g., proteins on viruses or bacteria) that can trigger an immune response, potentially causing disease if pathogenic. Antibodies (Choice A) are produced by B cells to neutralize antigens. T-Lymphocytes (Choice C) and macrophages (Choice D) are immune cells that respond to antigens, not the substances themselves, making Choice B the correct term.
