Core temperature changes...

Correct Answer: B

Rationale: The correct answer is B. Core temperature is regulated by the body's internal mechanisms to maintain homeostasis. It does not change significantly under normal conditions. A, C, and D are incorrect because core temperature is not directly influenced by environmental changes, night-time, or unspecified factors.

Correct Answer: B

Rationale: The correct answer is B: Increased temperature. When a person is stressed, their body releases stress hormones like adrenaline, which can lead to an increase in body temperature. This physiological response is known as the "fight or flight" response, where the body prepares to respond to a perceived threat. Increased temperature helps increase blood flow and oxygen to muscles to facilitate a quick response. Choice A (Decreased temperature) is incorrect because stress typically leads to an increase in temperature due to the activation of the body's stress response system. Choices C and D are incomplete and do not provide any information related to the physiological response to stress.

Correct Answer: B

Rationale: The correct answer is B: Sing happy birthday first. This step ensures that you wash your hands for at least 20 seconds, which is recommended by health experts to effectively remove germs. Singing happy birthday twice helps track the time and ensures thorough handwashing. Choice A is incorrect as opening the faucet first does not address the crucial 20-second handwashing duration. Choices C and D are incomplete and do not provide any relevant information on proper handwashing technique.

Correct Answer: A

Rationale: The correct answer is A: Daily exercises. Health promotion involves encouraging individuals to adopt healthy behaviors to prevent illness and improve overall well-being. Daily exercises contribute to physical fitness, weight management, and disease prevention. Regular physical activity boosts immune function, reduces stress, and lowers the risk of chronic conditions like heart disease and diabetes. In contrast, giving immunizations to infants (choice B) is a vital component of disease prevention but is not synonymous with health promotion, which encompasses a broader range of lifestyle choices. Choices C and D are likely incorrect as they are not provided, and do not align with the concept of health promotion.
