During an outbreak of measles, nurses are giving measles vaccinations to susceptible persons. Which of the following best describes the type of immunity that will follow the administration of these injections?
Herd immunity
Natural immunity
Acquired immunity
Active immunity
The Correct Answer is D
A. Herd immunity: Herd immunity occurs when a large portion of the population is immune, reducing the spread of disease. However, the individual receiving the vaccine develops active immunity, not herd immunity.
B. Natural immunity: Natural immunity occurs after infection and recovery, not from vaccination.
C. Acquired immunity: While acquired immunity includes both active (vaccination or infection) and passive (antibodies from mother or immunoglobulin) immunity, the most specific answer is active immunity.
D. Active immunity: Vaccines stimulate the immune system to develop long-term immunity by producing antibodies against the virus.

Correct Answer is B
Explanation
A. Endemic: An endemic disease is one that is consistently present in a population at expected levels, such as malaria in some tropical regions. Food poisoning outbreaks are not endemic.
B. Epidemic: An epidemic occurs when there is a sudden increase in cases of a disease within a specific population, as seen in this outbreak of food poisoning among picnic attendees.
C. Pandemic: A pandemic affects multiple countries or continents, which does not apply to this localized outbreak.
D. Polidemic: The term "polidemic" is not commonly used in epidemiology; the correct term for a localized outbreak is "epidemic."
Correct Answer is A
Explanation
A. Having the knowledge and skill set needed to advocate for the patient, but not being able to act on it due to not having the authority to do so. Moral distress occurs when a nurse knows the right action to take but is constrained by external factors such as policies, hierarchy, or legal limitations.
B. Having the authority to call off a code, then realizing the decision was harmful to the patient. This describes moral regret or ethical uncertainty, not moral distress. Moral distress occurs when a nurse is unable to act according to their ethical beliefs.
C. Having the authority to override a physician's order for pain medication. This describes an ethical dilemma rather than moral distress. Moral distress arises when a nurse cannot act despite knowing the right course of action.
D. Having the knowledge and skill set needed to provide culturally competent care. Cultural competence is an important aspect of nursing, but it does not describe moral distress, which involves ethical conflict and external barriers.
