Question 1 of 5
A school nurse wants to decrease the incidence of obesity in elementary school children. Which of
Correct Answer: A
Rationale: The correct answer is A because educating students on the importance of exercise and physical fitness promotes long-term healthy habits. This approach focuses on prevention rather than intervention, empowering children to make informed choices.
Choice B may help students make healthy food choices but doesn't address the importance of physical activity.
Choice C may lead to stigma and doesn't promote positive behavior change.
Choice D is not recommended as putting students on a diet without proper guidance can be harmful.
Question 2 of 5
A nurse advises a client with osteoporosis to have three servings of milk or dairy products daily.
Correct Answer: A
Rationale: The correct answer is A: Primary prevention. This recommendation aims to prevent osteoporosis from developing in the first place by promoting adequate calcium intake. Primary prevention focuses on reducing the risk factors and promoting healthy behaviors to prevent the onset of a disease.
Choices B, C, and D are incorrect because they are related to different stages of disease prevention and management. Secondary prevention involves early detection and treatment to prevent complications, tertiary prevention focuses on managing the complications of a disease, and treatment without prevention (choice
D) implies addressing the disease after it has already developed.
Question 3 of 5
A nurse has only a regular blood pressure cuff when conducting a health screening for all of the
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.
Question 4 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 5 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.
