Which of the following statements about children and environmental hazards is correct?
The incidence of asthma among children has been decreasing.
Children are more susceptible to environmental toxins because of their smaller size.
Children are more susceptible to cancer if they have a family history of the disease.
The prevalence of autism is directly related to the increase in environmental toxins.
The Correct Answer is B
A. The incidence of asthma among children has been decreasing: The incidence of childhood asthma has been increasing due to rising air pollution, allergens, and environmental triggers.
B. Children are more susceptible to environmental toxins because of their smaller size: Due to their lower body weight, developing organs, and higher metabolic rate, children absorb toxins more readily and are more vulnerable to harmful effects.
C. Children are more susceptible to cancer if they have a family history of the disease: While family history plays a role, environmental exposures (e.g., radiation, chemicals) also contribute significantly to childhood cancer risk.
D. The prevalence of autism is directly related to the increase in environmental toxins: While research is ongoing, no definitive causal link has been established between environmental toxins and autism. Autism is influenced by multiple genetic and environmental factors.

Correct Answer is D
Explanation
A. "These medications are important. Do your best to pay for them." This dismisses the patient's financial hardship and does not offer assistance or alternatives.
B. "Let's go through these medications and see which ones we can delete." Nurses should not arbitrarily stop medications. Only a healthcare provider (e.g., physician, pharmacist) should determine if any medications can be discontinued or adjusted.
C. "You can get these medicines at a clinic for free." This is misleading because not all clinics offer free medications. The nurse should verify available programs before making such a statement.
D. "Let's see if we can get some help from Medicare to help you pay for these medications." This response provides a realistic solution by exploring financial assistance options, such as Medicare Part D, Medicaid, or other drug assistance programs.
Correct Answer is B
Explanation
A. Number of true negatives / (true negatives + false positives): This formula is used to calculate specificity, not incidence.
B. Number of new cases in a period of time / total population × base multiple of 10: Incidence rate measures the number of new cases of a disease occurring in a population during a specific period. It is expressed per a base population size (e.g., per 1,000 or 100,000 people) to allow for comparisons across different populations.
C. Number of true positives / (true positives + false negatives): This formula is used to calculate sensitivity, not incidence.
D. Number of new cases + number of old cases in a period of time / total population × base multiple of 10: This describes prevalence, which includes both new and existing cases, not incidence.
