A nursing preceptor is reviewing life expectancy in the twentieth century with a new nurse. The nurse should recognize that which of the following was most responsible for the dramatic increase in life expectancy during the twentieth century.
Advances in surgical techniques and procedures
Sanitation and other public health activities
Technology increases in the field of medical laboratory research
Use of antibiotics to fight infections
The Correct Answer is B
Choice A reason: Advances in surgical techniques and procedures have improved the outcomes of many patients, but they are not the main factor for the increase in life expectancy. Surgical interventions are often costly, risky, and inaccessible to many people, especially in developing countries.
Choice B reason: Sanitation and other public health activities have had a significant impact on reducing mortality from infectious diseases, such as cholera, typhoid, and tuberculosis. These activities include providing safe water, improving hygiene, promoting vaccination, and controlling vector-borne diseases. Sanitation and public health measures are relatively low-cost, effective, and preventive strategies that can benefit large populations.
Choice C reason: Technology increases in the field of medical laboratory research have contributed to the diagnosis and treatment of many diseases, such as cancer, diabetes, and genetic disorders. However, these technologies are often expensive, complex, and dependent on specialized equipment and personnel. Therefore, they are not the main reason for the increase in life expectancy.
Choice D reason: The use of antibiotics to fight infections has been a major breakthrough in medicine, saving millions of lives from bacterial infections. However, antibiotics have also led to the emergence of antibiotic-resistant bacteria, which pose a serious threat to public health. Moreover, antibiotics are not effective against viral infections, such as influenza, HIV, and COVID-19. Therefore, antibiotics are not the most responsible factor for the increase in life expectancy.

Correct Answer is C
Explanation
Choice A reason: Repeat dose in 1 hour for unrelieved headache. This instruction is incorrect because sumatriptan should not be taken more than twice in 24 hours. Taking too much sumatriptan can cause serious side effects, such as high blood pressure, stroke, or heart problems.
Choice B reason: Chew the tablet well before swallowing. This instruction is incorrect because sumatriptan tablets should be swallowed whole with water. Chewing the tablet may affect its absorption and effectiveness.
Choice C reason: If you experience chest pain, call your physician immediately. This instruction is correct because chest pain is a serious and potentially life-threatening side effect of sumatriptan. Chest pain may indicate a heart attack or coronary artery spasm, which require immediate medical attention.
Choice D reason: Take daily to prevent headaches. This instruction is incorrect because sumatriptan is not a preventive medication for migraines. It is only used to treat acute migraine attacks when they occur. Taking sumatriptan daily can cause rebound headaches, which are worse and more frequent than the original ones.

Correct Answer is C
Explanation
Choice A reason: Completing a survey of the various ethnicities represented in the nurse's community is a good way to learn about diversity, but it is not the first step in developing cultural competence. The nurse should first examine their own cultural background and biases, and how they affect their interactions with clients.
Choice B reason: Studying the beliefs and traditions of persons living in other cultures is a valuable way to gain knowledge and understanding, but it is not the first step in developing cultural competence. The nurse should first be aware of their own cultural values and assumptions, and how they influence their perceptions and judgments.
Choice C reason: Considering how the nurse's own personal beliefs and decisions are reflective of their culture is the first step in developing cultural competence. The nurse should recognize that culture is not only about ethnicity, but also about age, gender, religion, education, socioeconomic status, and other factors. The nurse should also acknowledge that culture is dynamic and complex and that each person has a unique cultural identity.
Choice D reason: Inviting a family from another culture to join the nurse for an event is a nice way to show respect and interest, but it is not the first step in developing cultural competence. The nurse should first develop self-awareness and sensitivity, and avoid making stereotypes or generalizations about other cultures.
