A nurse is triaging clients in the emergency department. Which of the following clients should the nurse ask the provider to care for first?

Correct Answer: C

Rationale: The correct answer is C. The school-age child with acute epiglottitis should be cared for first due to the potential for airway compromise and respiratory distress, as evidenced by drooling and absence of spontaneous cough. This is an emergency situation that requires immediate intervention to prevent airway obstruction and ensure adequate oxygenation. Choice A is not the priority as a pulse oximetry reading of 95% is adequate, and the child is already receiving oxygen. Choice B, the toddler with otitis media, can be managed with antipyretics and antibiotics for the ear infection but does not have an immediate life-threatening condition. Choice D, the adolescent with sickle cell disease and pain, should receive pain medication but does not have an acute airway emergency like the child with epiglottitis. It is crucial to prioritize care based on the urgency and potential severity of the condition to ensure the best outcomes for the patients.

Correct Answer: B

Rationale: The correct answer is B: Independent variable. The independent variable is the one that the researcher manipulates or controls to observe its effect on the dependent variable. It is the cause in a cause-and-effect relationship. The dependent variable, on the other hand, is the outcome that is measured and affected by the independent variable. Control variables are factors that are held constant to prevent them from influencing the results. Moderating variables are factors that can influence the relationship between the independent and dependent variables, but they are not directly manipulated by the researcher in the study.

Correct Answer: B

Rationale: The correct answer is B because analyzing pre-existing health records is an example of secondary data analysis, where researchers use data that was collected by someone else for a different purpose. This method is cost-effective and time-saving. Choice A involves collecting original data, not analyzing existing data. Choice C involves conducting primary data collection through interviews. Choice D involves conducting an experimental study, not analyzing existing data. In summary, B is correct as it aligns with the definition and characteristics of secondary data analysis, while the other choices involve primary data collection methods.

Correct Answer: C

Rationale: The correct answer is C: Review the events leading up to each medication administration error. This should be initiated first because it allows the committee to identify root causes of errors and implement targeted interventions. By understanding the sequence of events, the committee can uncover system weaknesses or breakdowns that contribute to errors. A: Providing an inservice may be helpful, but without understanding the specific factors leading to errors, it may not address the underlying issues causing the errors. B: Requiring a competency exam is important, but addressing the system failures that lead to errors should take priority to prevent future errors. D: Developing a quality improvement program is necessary, but without a thorough understanding of the events leading to errors, the program may not effectively target the root causes of errors.

Correct Answer: A

Rationale: The correct answer is A, using 2 hands for deep palpation. Deep palpation requires more pressure and depth to assess internal organs or structures. Using 2 hands allows for better control, even pressure distribution, and more thorough examination. Using 2 fingers (option B) may not provide enough force for deep palpation, while options C and D are incomplete choices. In summary, using 2 hands is the best approach for deep palpation due to its effectiveness in applying sufficient pressure and achieving accurate results.
