Care of Vulnerable Populations Questions
Question 1 of 5
Persons with immune deficiencies may have a negative tuberculosis (TB) skin test even though they are infected. Knowing this, what would the nurse expect to see in the test results when a TB skin test is given to persons with AIDS?
Correct Answer: C
Rationale: The correct answer is C: Decreased sensitivity. Persons with AIDS have compromised immune systems, which can lead to a false negative TB skin test result even if they are infected. Decreased sensitivity means the test may not correctly identify true positive cases, leading to false negatives. A: Decreased positive predictive value - This is not the correct answer because positive predictive value refers to the likelihood that a positive test result truly indicates the presence of the condition. Sensitivity and specificity impact the accuracy of the test results. B: Decreased reliability - This is not the correct answer as reliability refers to the consistency of the test results. Sensitivity specifically relates to the ability of the test to correctly identify those with the condition. D: Decreased specificity - This is not the correct answer as specificity refers to the ability of the test to correctly identify those without the condition. Sensitivity, not specificity, is affected in this scenario due to the immune deficiencies in persons with AIDS.
Question 2 of 5
A nurse reports that in comparison to all the children in a particular school, the children who are members of the Cub Scouts have 0.3 risk for obesity before entering the sixth grade. What would you recommend to the new parents of two boys who had just moved into this school's neighborhood?
Correct Answer: D
Rationale: The correct answer is D because as a nurse, it is important to provide evidence-based information to parents and let them make informed decisions. By sharing the finding with the parents, they can assess the risk and decide whether enrolling their sons in Cub Scouts is suitable for them. This empowers parents to make choices based on available information. Choice A is incorrect because it assumes a direct causation between Cub Scouts and obesity without considering other factors. Choice B is incorrect because as a nurse, providing relevant information to parents is essential for their decision-making process. Choice C is incorrect because it imposes a decision on the parents without allowing them to consider all the factors involved.
Question 3 of 5
What kind of study should the nurse researcher choose if the goal is to identify the long-term benefits and risks of a particular nursing intervention for senior citizens living in the community?
Correct Answer: C
Rationale: The correct answer is C: Clinical trial. A clinical trial is the best study design to identify long-term benefits and risks of a nursing intervention as it involves controlled experimentation, randomization, and follow-up over an extended period. It allows for comparison between intervention and control groups, ensuring the reliability of results. Cross-sectional studies (A) are snapshots in time and do not provide longitudinal data. Ecologic studies (B) analyze population-level data and may not capture individual-level effects. Retrospective analysis (D) looks back at past data and may not be suitable for studying long-term effects prospectively.
Question 4 of 5
Some nurses decide to hold a health screening at a large urban mall. What variables will help the nurses determine which screenings to do? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B, as it is essential to consider the specific health problems that the population at the mall is at risk for. This information will help the nurses prioritize which screenings to conduct based on the prevalent health issues in that community. A, C, and D are incorrect: A: The availability of space for individuals to lie down is important for post-testing care but does not directly help determine which screenings to conduct. C: Privacy considerations are important but do not directly impact the selection of health screenings. D: While follow-up care is crucial, the availability of healthcare providers does not guide the selection of screenings based on the population's specific health risks.
Question 5 of 5
The nurse is assessing a family that includes an adult and a school-aged child named Jackson. Which of the following questions should the nurse prioritize to ask the adult?
Correct Answer: B
Rationale: The correct answer is B: "What is your relationship to Jackson?" This question should be prioritized because it helps the nurse understand the family dynamics and the adult's role in Jackson's life. By knowing the adult's relationship to Jackson, the nurse can better assess the support system and decision-making authority within the family. Incorrect choices: A: Asking about concerns regarding the son's health is important but not the priority as understanding the relationship dynamics first. C: Inquiring about the other parent as a source of support is relevant but secondary to establishing the primary relationship. D: Asking about the number of other children is less crucial in this context compared to identifying the adult's relationship to Jackson.
