Question 1 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 2 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 3 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 4 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 5 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.
