Question 1 of 5
A nurse is administering a tuberculosis skin test to a client who has AIDS. Which of the following
Correct Answer: A
Rationale: The correct answer is A: Decreased positive predictive value. In clients with AIDS, their compromised immune system can lead to false-negative results on the tuberculosis skin test. This decreases the test's ability to accurately predict the presence of tuberculosis if the result is positive.
Choice B, decreased reliability, is not specific to the client's condition in this scenario.
Choices C and D, decreased sensitivity and specificity, respectively, are not directly impacted by the client having AIDS and are more related to the test's overall performance characteristics.
Question 2 of 5
Persons in an auditorium may have been exposed to a disease. If they are infected, it is crucial that
Correct Answer: A
Rationale: The correct answer is A: The negative predictive value. In this scenario, it is crucial to know the likelihood of a person not being infected if the test result is negative. Negative predictive value assesses the probability of a person truly being disease-free when the test result is negative. This is important for determining the risk of spreading the disease within the auditorium.
Explanation for other choices:
B: The positive predictive value - While important in clinical settings, in this case, determining the accuracy of positive test results is not as critical as ruling out disease transmission.
C: The sensitivity of the test - Sensitivity measures the ability of the test to correctly identify those with the disease, not necessarily ruling out disease transmission among those with negative results.
D: The specificity of the test - Specificity measures the ability of the test to correctly identify those without the disease, which is not directly related to preventing disease spread in this context.
Question 3 of 5
A woman is sitting in a corner of the clinical waiting room, crying audibly. The nurse asks, Whats
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.
Question 4 of 5
The administration at a local medical center examines the trends in health problems when
Correct Answer: A
Rationale: The correct answer is A because using local data from a professional survey in the city allows the medical center to understand specific health trends within their community. This data is most relevant and directly applicable to their patient population.
Choice B, the National Health Interview Survey, provides broader national data, which may not reflect local health issues accurately.
Choice C, the National Hospital Discharge Survey, focuses on hospitalized patients, not community-wide health trends.
Choice D, state vital statistics, may offer general health information but lacks the specificity needed for the medical center's analysis.
Question 5 of 5
Statistics clearly demonstrate that there are significantly more cases of a disease in one particular
Correct Answer: A
Rationale: The correct answer is A: A cultural or ethnic concentration in the neighborhood. This is because cultural or ethnic factors can influence health behaviors, access to healthcare, genetic predispositions, and environmental exposures, all of which can impact disease prevalence. Geographical location (
B) may play a role in some cases but is not as directly linked to disease patterns as cultural factors.
Choice C suggests randomness, which is unlikely given the clear statistical demonstration mentioned in the question. The time of year (
D) is not a significant factor unless it is directly related to cultural or ethnic practices affecting disease spread.
