After opening the windows, FIRST

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. 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.

Correct Answer: A

Rationale: The correct answer is A: liquid soap. Research shows that liquid soap is more hygienic as it is less likely to harbor bacteria compared to solid soap. Liquid soap also allows for easier dispensing and proper handwashing technique. Solid soap can accumulate germs on its surface and may not be as effective in cleaning hands thoroughly. Choice B is incorrect due to the hygiene concerns associated with solid soap. Choices C and D are not provided, hence cannot be considered as correct answers.

Correct Answer: B

Rationale: The correct answer is B: Consult your doctor. This is the best option because doctors are trained professionals who can provide accurate diagnosis and treatment for persistent symptoms. Asking your mother (A) may not provide the necessary medical expertise. Diagnosing the patient (C) is not appropriate for a non-medical professional. Option D is incomplete and does not offer a solution to the problem. Consulting a doctor is the most logical and effective course of action in this situation.

Correct Answer: B

Rationale: The correct answer is B: Let it be. Popping pustules can lead to infection, scarring, and spread of bacteria. By leaving it alone, the body can naturally heal the pustule without causing further harm. It is important to avoid touching or picking at the pustule to prevent complications. Other choices are incorrect because they involve actions that can worsen the condition or lead to further issues.
