Which of the following is an example of secondary data analysis?

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: 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.

Correct Answer: B

Rationale: The correct answer is B (Above 3 feet in radius) because airborne diseases can spread through respiratory droplets that can travel farther than 3 feet. This is particularly important for diseases like COVID-19 and tuberculosis. Choice A (3 feet in radius) is incorrect as it underestimates the distance respiratory droplets can travel. Choices C and D are incomplete and do not provide a clear answer. Remember, maintaining a safe distance, wearing masks, and proper ventilation are key in preventing the spread of airborne diseases.

Correct Answer: B

Rationale: The correct answer is B because palpating blood pressure allows for assessing the systolic pressure accurately by feeling the pulse disappear and reappear. Diastolic pressure is not accurately determined by palpation alone. Choice A is incorrect because palpation does not provide a reliable method for determining diastolic pressure. Choices C and D are empty and do not offer any valid explanation for palpatory blood pressure readings.

Correct Answer: B

Rationale: The correct answer is B: Objective data. Objective data refers to information that is observable, measurable, and based on facts rather than opinions or interpretations. Signs or overt data are considered objective because they are observable and can be measured or documented. Subjective data (choice A) is based on personal opinions, feelings, or interpretations and is not considered signs or overt data. Choices C and D are likely irrelevant options as they do not pertain to the given question.
