Oxygen-rich blood is pumped from the left ventricle via the

Correct Answer: B

Rationale: The correct answer is B: Aorta. The left ventricle pumps oxygen-rich blood into the aorta, which is the main artery that carries blood away from the heart to the rest of the body. This is a crucial step in the systemic circulation of the circulatory system. The aorta then branches out into smaller arteries, leading to the capillaries where gas exchange occurs. Explanation for Incorrect Choices: A: Right ventricle - The right ventricle pumps deoxygenated blood to the lungs, not oxygen-rich blood. C: Capillaries - Capillaries are tiny blood vessels where gas exchange occurs, but blood is not pumped directly from the left ventricle to capillaries. D: Veins - Veins carry blood back to the heart, but they do not receive blood directly from the left ventricle.

Correct Answer: B

Rationale: The correct answer is B: Paraplegia. Paraplegia specifically refers to the loss of function of the lower body and legs. "Para" means alongside, indicating paralysis affecting both legs. Concussion (A) is a head injury affecting cognitive function, not related to lower body paralysis. Quadriplegia (C) involves paralysis of all four limbs, not just the lower body. Hemiplegia (D) is paralysis affecting one side of the body, not limited to the lower body. Thus, paraplegia is the most appropriate term for the loss of function in the lower body and legs.

Correct Answer: A

Rationale: Rationale for choice A being correct: As women age, hormone levels decrease, leading to menopause. This is a normal age-related change due to the decline in estrogen and progesterone production by the ovaries. Menopause typically occurs around the age of 45-55. Summary of why other choices are incorrect: B: Testosterone levels in males actually decrease with age, leading to symptoms like decreased muscle mass and libido. C: Insulin production may decrease or remain stable with age, but it does not typically increase as a normal age-related change. D: While the body's ability to handle stress may change with age, it does not necessarily improve as a normal age-related change.

Correct Answer: D

Rationale: The correct answer is D: 4. A quad cane has four feet for stability and support. Having four feet provides better balance and weight distribution compared to fewer feet. Option A (1) is incorrect because a quad cane has multiple feet, not just one. Option B (2) is incorrect as it does not provide enough support for balance. Option C (3) is also incorrect as it falls short of the required stability that four feet offer. Therefore, the correct choice is D as it aligns with the design and purpose of a quad cane.

Correct Answer: C

Rationale: The correct answer is C because listening to the family and friends allows them to express their emotions and thoughts, which can be comforting and therapeutic. It shows empathy and support during a difficult time. Choice A is incorrect as calming upset family members is important, but listening is more effective. Choice B is incorrect as invalidating their emotions can be harmful. Choice D is incorrect as showing empathy and compassion is crucial in supporting the grieving process.
