Left eye, medical term

Correct Answer: A

Rationale: The correct answer is A: OS. In medical terminology, "OS" stands for "oculus sinister," which means the left eye. This Latin term is commonly used in medical charts and prescriptions to indicate the left eye specifically. Explanation: - "OD" refers to "oculus dexter," which means the right eye. - "OU" stands for "oculus uterque," meaning both eyes. - Choice D is incorrect as it does not provide a valid medical term for the left eye. Therefore, the correct answer is A because it accurately represents the left eye in medical terminology.

Rationale: Step 1: Feet together reduces stability and increases risk of falling. Step 2: Carrying object with feet together restricts balance and proper weight distribution. Step 3: Feet apart provides a wider base, enhancing stability and reducing strain on the body. Summary: Option B is correct as it promotes proper body mechanics by ensuring a wider base of support. Choices A, C, and D are incorrect as they do not address the importance of base support and can lead to increased risk of injury.

Correct Answer: B

Rationale: The correct answer is B (30 minutes) because of the refractory period that occurs in men after ejaculation. During this time, men typically experience a decrease in sexual arousal and are unable to achieve another erection or ejaculation immediately. This refractory period lasts around 30 minutes on average, although it can vary among individuals. Choice A (None) is incorrect because it does not align with the physiological refractory period that occurs after ejaculation. Choice C (Anytime at will) is incorrect as it implies that men can immediately engage in sexual activity again after ejaculation, which is not typically the case due to the refractory period. Choice D is incomplete, so it cannot be considered as a valid option.

Correct Answer: B

Rationale: The correct answer is B: Take bp while sleeping. This is because blood pressure should ideally be measured during sleep to get an accurate reading unaffected by external factors such as stress or physical activity. Choice A is incorrect because past blood pressure readings may not reflect the current status. Choices C and D are incomplete and do not offer a viable alternative method for measuring blood pressure.

Correct Answer: B

Rationale: The correct answer is B because health encompasses mental, physical, and emotional well-being. Mental health refers to cognitive and emotional aspects, physical health relates to the body's physical well-being, and emotional health pertains to managing emotions effectively. Choice A is incorrect because it only mentions physical and emotional well-being, leaving out mental health. Choice C and D are incomplete options and do not provide a comprehensive definition of health. Therefore, option B is the most appropriate choice as it covers all aspects of health.
