Persons in an auditorium may have been exposed to a disease. If they are infected, it is crucial that they receive immediate treatment and not take the disease home to their families. Which of the following characteristics would be most important to consider when selecting the screening test to be used?
- A. The negative predictive value
- B. The positive predictive value
- C. The sensitivity of the test
- D. The specificity of the test
Correct Answer: C
Rationale: The correct answer is C: The sensitivity of the test. Sensitivity measures the ability of a test to correctly identify individuals who have the disease (true positives). In this scenario, selecting a screening test with high sensitivity is crucial to ensure that infected individuals are accurately identified and receive immediate treatment to prevent spreading the disease to their families.
A: The negative predictive value - This measures the probability that individuals with a negative test result truly do not have the disease and is not as important in this case where immediate treatment is vital.
B: The positive predictive value - This measures the probability that individuals with a positive test result truly have the disease and is not as critical as sensitivity in this context.
D: The specificity of the test - This measures the ability of a test to correctly identify individuals who do not have the disease (true negatives) and is not the most important consideration when the goal is to identify infected individuals for immediate treatment.

A nurse is investigating a bacterial illness that has caused a health problem in the community. Only
- A. A strong public health structure ready to respond effectively to a crisis
- B. Public healths need for additional funding and resources
- C. The unrecognized importance of nurses in lowering health care costs
- D. Lack of adequate vaccines to meet communitys needs
Correct Answer: A
Rationale: The correct answer is A: A strong public health structure ready to respond effectively to a crisis. A strong public health structure is essential for investigating and managing a bacterial illness outbreak in a community. Public health infrastructure includes surveillance systems, trained personnel, communication networks, and resources necessary to respond promptly and effectively to health crises. Without a robust public health structure, identifying the source of the illness, implementing control measures, and preventing further spread would be challenging.
Choice B is incorrect because while additional funding and resources are important for public health, they do not address the immediate need for an effective response to the crisis. Choice C is incorrect as it is not directly related to the investigation of the bacterial illness. Choice D is incorrect as the lack of adequate vaccines may contribute to the spread of the illness but does not address the broader issue of public health infrastructure.
A woman is sitting in a corner of the clinical waiting room, crying audibly. The nurse asks, Whats
- A. The negative predictive value of mammography
- B. The positive predictive value of mammography
- C. The reliability of mammography
- D. The validity of mammography
Correct Answer: A
Rationale: The correct answer is A: The negative predictive value of mammography. The nurse's question is related to predicting the likelihood of a negative outcome, which aligns with the concept of negative predictive value in the context of mammography. Negative predictive value assesses the probability that a negative test result is truly negative. The nurse's question does not pertain to positive predictive value (B), reliability (C), or validity (D) of mammography. These options are not relevant to the situation described and do not address the nurse's inquiry. Therefore, A is the correct choice as it directly corresponds to the nurse's query about the likelihood of a negative outcome in the given scenario.
A nurse has only a regular blood pressure cuff when conducting a health screening for all of the
- A. Reliability
- B. Sensitivity
- C. Specificity
- D. Validity
Correct Answer: C
Rationale: The correct answer is C: Specificity. Specificity refers to the ability of a test to correctly identify those without a certain condition as negative. In this scenario, using a regular blood pressure cuff may not be specific enough to accurately identify individuals who do not have high blood pressure. The cuff may give false positive results, leading to unnecessary concern or further testing. The other choices are incorrect because: A - Reliability refers to the consistency of results, not the accuracy of identifying those without a condition. B - Sensitivity is the ability to correctly identify those with a certain condition as positive, not those without it. D - Validity is the overall accuracy of a test, which includes both sensitivity and specificity, but in this case, specificity is more relevant.
A nurse is employed as a nurse epidemiologist. Which of the following activities would most likely be completed by the nurse?
- A. Eliciting the health history of a client presenting with an illness
- B. Evaluating the number of clients presenting with similar diseases
- C. Performing a physical examination of an ill client
- D. Providing treatment and health education to a client with a disease
Correct Answer: A
Rationale: The correct answer is A: Eliciting the health history of a client presenting with an illness. As a nurse epidemiologist, the nurse's primary role is to investigate and analyze patterns of disease occurrence. By eliciting the health history of a client presenting with an illness, the nurse can gather essential data to identify potential sources of infection, risk factors, and patterns of disease spread within a population. This activity aligns with the epidemiological approach of understanding the distribution and determinants of health-related states.
Incorrect choices:
B: Evaluating the number of clients presenting with similar diseases - While this may be part of the nurse epidemiologist's duties, it does not directly involve gathering individual health histories to track disease patterns.
C: Performing a physical examination of an ill client - This task is more aligned with clinical nursing practice rather than epidemiological investigation.
D: Providing treatment and health education to a client with a disease - This is within the scope of direct patient care and does not focus on population
The tendency to ignore all differences between cultures and to act as though the differences do not exist is identified by what term?
- A. Cultural conflict
- B. C M
- C. Culture shock U S N T O
- D. Cultural blindness
Correct Answer: D
Rationale: The correct answer is D: Cultural blindness. Cultural blindness refers to the tendency to ignore cultural differences and act as though they do not exist. This term highlights the lack of awareness or recognition of the diversity and nuances of various cultures. It can lead to misunderstandings, miscommunication, and insensitivity towards individuals from different cultural backgrounds.
A: Cultural conflict involves disagreements or tensions arising from cultural differences, which is not the same as ignoring differences.
B: C M, C: Culture shock U S N T O, E:, F:, G: do not provide relevant options.
In summary, cultural blindness is the correct term as it specifically addresses the act of disregarding cultural differences, while the other choices either address different concepts or are irrelevant.
