Correct Answer: D

Rationale: Chest pain radiating to the left arm is a classic symptom of a myocardial infarction (heart attack) in individuals with coronary artery disease. This finding indicates that the heart muscle may not be receiving adequate oxygen, which requires immediate intervention to prevent further damage or complications. The other assessment findings (heart rate of 90 beats per minute, respiratory rate of 20 breaths per minute, blood pressure of 130/80 mm Hg) are within normal limits and do not suggest an acute, life-threatening condition like myocardial infarction.

Correct Answer: A

Rationale: The correct answer is A: Infection is acquired when anthrax spores enter a host. Anthrax is primarily transmitted through spores entering the body, either through the skin, inhalation, or ingestion. Person-to-person transmission of anthrax is extremely rare and not a significant mode of transmission. Choices B and C are incorrect because mature anthrax bacteria do not live dormant on inanimate objects, and spores can survive for extended periods outside a living host. Choice D is incorrect as anthrax is not transmitted by respiratory droplets from person to person.

Correct Answer: C

Rationale: The recommended option for managing stress during final exams is a balanced and nutritious meal. Fruit salad with fresh berries and oranges, chicken vegetable soup, and tea offer a variety of nutrients and antioxidants that can help combat stress. Option A is not ideal as it includes high-fat and high-calorie foods. Option B is a good choice, but Option C provides a wider range of nutrients and hydration. Option D is a healthy choice with a variety of proteins and vitamins, but Option C offers lighter options that may be easier to digest during stressful times.

Correct Answer: D

Rationale: Creating a confidential hotline for reporting substance abuse should be prioritized because it offers a safe and accessible way for individuals to seek help and support for their substance abuse issues. This intervention allows individuals to report their concerns anonymously and seek guidance without fear of judgment or repercussions. Providing education on the dangers of substance abuse (Choice A) is important but may not be as immediately impactful as offering a direct avenue for help. Setting up a support group (Choice B) is valuable but may not reach as many individuals or provide the same level of anonymity as a confidential hotline. Partnering with law enforcement (Choice C) is crucial for addressing substance abuse issues from a legal perspective but may not directly address the immediate needs of individuals seeking help.

Correct Answer: A

Rationale: The correct answer is A: motor vehicle accidents. Motor vehicle accidents are a significant cause of spinal cord injuries among adolescents due to the high impact forces involved. While violent assault, sports injuries, and falls can also lead to spinal cord injuries, statistics show that motor vehicle accidents are a leading cause in this age group. Educating adolescents about the risks and preventive measures related to motor vehicle accidents is crucial in promoting their safety and well-being.
