Correct Answer: A

Rationale: The school classroom is the most suitable setting to increase preadolescents' participation in a health education program. At the age of 10, children are accustomed to the school environment, making it familiar and comfortable for them. This familiarity can help reduce anxiety and increase engagement during the program. Community centers may be less familiar and could pose distractions, potentially reducing participation. Conducting the program at the home of one of the children may lead to unequal access for other participants and may not provide the necessary facilities for an educational session. A local place of worship may not be perceived as a neutral or suitable environment for a health education program, potentially hindering participation.

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: 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: 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.

Correct Answer: C

Rationale: The correct answer is C: Absence of breath sounds. This finding is concerning in a client with asthma as it may indicate a severe asthma exacerbation, airway obstruction, or pneumothorax, all of which require immediate intervention. Absence of breath sounds suggests a lack of airflow in the lungs, which is a critical sign that should prompt immediate action. Expiratory wheezes (choice A) are common in asthma and may not warrant immediate intervention unless severe. An increased respiratory rate (choice B) is expected in a client with asthma experiencing shortness of breath, but it does not indicate an immediate threat to the airway. Frequent coughing (choice D) is a common symptom in asthma exacerbations but does not signify an immediate need for intervention as it can be managed with appropriate asthma treatments.
