Which of the following is an example of qualitative data?

Correct Answer: C

Rationale: The correct answer is C because participant descriptions of their experiences are subjective and descriptive in nature, making them qualitative data. This type of data focuses on qualities, characteristics, and opinions rather than numerical values or measurements. A: Temperature measurements in Celsius are quantitative data as they provide numerical values. B: Scores on a standardized test are also quantitative data, representing numerical results. D: Number of students in a classroom is quantitative data, counting the quantity of students. In summary, qualitative data involves subjective descriptions and characteristics, while the other choices involve numerical values or quantities.

Correct Answer: B

Rationale: The correct answer is B: Hyperoxygenate before and after suctioning. This is crucial to prevent hypoxemia during and after suctioning, as it helps maintain adequate oxygen levels and reduce the risk of complications. Hyperoxygenation before suctioning ensures the patient starts with optimal oxygen saturation, while hyperoxygenation after suctioning helps restore oxygen levels that may have dropped during the procedure. This systematic approach promotes patient safety and minimizes potential respiratory distress. Choices A, C, and D are incorrect as they do not address the essential step of hyperoxygenation before and after suctioning, which is vital in maintaining patient oxygenation and preventing hypoxemia.

Correct Answer: B

Rationale: The correct answer is B: Warm air goes out. This is because when windows are opened, warm air, being less dense, rises and escapes to the outside. This creates a flow of air where warm air exits the room first before cold air enters, as cold air is denser and tends to stay lower. Choice A is incorrect as cold air typically enters after warm air exits. Choices C and D are not applicable as they do not provide any relevant information related to the scenario.

Correct Answer: B

Rationale: The correct answer is B: Cannot sleep. Stress can lead to sleep disturbances due to increased levels of cortisol, a stress hormone, disrupting the sleep-wake cycle. Lack of quality sleep can exacerbate stress and impact overall well-being. Choice A, unable to concentrate, may also occur with stress, but it is not as directly related to the physical factors mentioned in the question. Choice C and D are likely incorrect since they are not related to the physical effects of stress mentioned in the question.

Correct Answer: B

Rationale: The correct answer is B. Starting the collection at 10 am will capture the urine for the next 24 hours accurately. Discarding the 10 am urine ensures that the collection starts with the first morning urine, which is essential for an accurate 24-hour urine test. Choice A would not provide a full 24-hour sample, leading to inaccurate results. Choice C and D are incomplete and do not provide a logical approach for a 24-hour urine collection.
