Acne, cause

Correct Answer: B

Rationale: The correct answer is B: Unknown. Acne is a complex skin condition with various contributing factors such as genetics, hormones, bacteria, and inflammation. Scientific research has not definitively identified a single cause of acne, making it a multifactorial condition. Choice A is incorrect as there is no direct evidence linking peanuts or oily foods to acne development. Choice C and D are blank options and do not provide any relevant information. In summary, the correct answer is B because acne is not solely attributed to a single cause, and it is still not fully understood by medical experts.

Correct Answer: A

Rationale: Step 1: Loss of job is a situational stressor as it involves a significant change or loss in one's life, leading to emotional distress and uncertainty. Step 2: Job interview may cause stress, but it is a specific event, not a broader situational stressor like losing a job. Step 3: Choices C and D are incomplete, making them incorrect as they do not provide relevant information related to situational stressors. Summary: Loss of job is the correct answer as it aligns with the definition of a situational stressor, while the other choices are incorrect due to their lack of direct relevance to the concept.

Correct Answer: B

Rationale: The correct answer is B: 2.54 centimeters. This is because 1 inch is a unit of measurement in the Imperial system, and it is equivalent to 2.54 centimeters in the Metric system. This conversion factor is based on the international standard for length measurement. The other choices, such as A: Your thumb, do not provide an accurate or universally accepted measurement conversion and are therefore incorrect.

Correct Answer: A

Rationale: The correct answer is A because insomnia is a common symptom of depression. When someone is depressed, they may have difficulty falling asleep or staying asleep. This is often due to racing thoughts, feelings of worthlessness, or changes in brain chemistry. In contrast, the inability to cry (option B) is not a defining feature of depression. Options C and D are blank and irrelevant. In summary, the inability to sleep is a hallmark symptom of depression, making option A the correct choice.

Correct Answer: B

Rationale: The correct answer is B: Between the lips. Oral temperature measurement should be taken between the lips using a thermometer. This method ensures accurate reading by placing the thermometer in the sublingual pocket under the tongue. Choice A (Sublingual) is incorrect as it refers to the correct location within the oral cavity. Choice C and D are incomplete options and do not provide a valid alternative method for taking oral temperature.
