1. Which gland is located superior to the kidney?

• A. Pituitary
• B. Adrenal
• C. Hypothalamus
• D. Pancreas

Correct answer: B

Rationale: The adrenal gland is located superior to the kidney. Each kidney is surrounded by an adrenal gland, also known as the suprarenal gland, situated on top of the kidneys. The pituitary gland (A) is located in the brain, while the hypothalamus (C) is also in the brain, above the pituitary gland. The pancreas (D) is located in the abdomen, near the stomach and small intestine, not superior to the kidney.

2. Where is a gallstone most likely to cause pain?

• A. In the upper right quadrant of the abdomen
• B. In the lower right quadrant of the abdomen
• C. In the umbilical region
• D. Along the pelvic girdle

Correct answer: A

Rationale: A gallstone is most likely to cause pain in the upper right quadrant of the abdomen. This specific area corresponds to the location of the gallbladder. When a gallstone blocks the flow of bile from the gallbladder, it can lead to inflammation and pain in this region. The pain may also radiate to the back or right shoulder blade due to referred pain patterns associated with gallbladder issues. Choices B, C, and D are incorrect because gallstone pain is typically felt in the upper right quadrant of the abdomen, not the lower right quadrant, umbilical region, or along the pelvic girdle.

3. Which cut is considered a cross section?

• A. A sagittal or frontal section
• B. A cut along the coronal plane
• C. A cut along the median plane
• D. A cut through the transverse plane

Correct answer: D

Rationale: The correct answer is D: A cut through the transverse plane. A transverse plane cut, also known as a cross-section, divides the body or an organ into superior and inferior portions. This type of cut is perpendicular to the long axis of the body and is commonly used in medical imaging to display internal structures and organs in a horizontal view. Choices A, B, and C are incorrect because a sagittal or frontal section (A) divides the body into left and right portions, a cut along the coronal plane (B) separates the body into anterior and posterior parts, and a cut along the median plane (C) divides the body into equal left and right halves.

4. Which vitamin is essential for vision and skin health?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: A

Rationale: Vitamin A is the correct answer. It is crucial for maintaining healthy vision and skin. Vitamin A plays a vital role in supporting normal vision, skin health, and immune function. Specifically, it is important for the health of the retina and is essential for the formation of rhodopsin, a protein in the retina necessary for low-light and color vision. Vitamin C (Choice B) is important for collagen synthesis and immune function, but it is not primarily associated with vision health. Vitamin D (Choice C) is crucial for bone health and immune function, while Vitamin E (Choice D) acts as an antioxidant, protecting cells from damage, but neither are primarily linked to vision and skin health like Vitamin A.

5. What is the function of the lungs in the respiratory system?

• A. To filter blood
• B. To exchange gases
• C. To produce energy
• D. To remove waste products

Correct answer: B

Rationale: The correct function of the lungs in the respiratory system is to exchange gases. The lungs facilitate the exchange of oxygen and carbon dioxide between the air we breathe in and the blood, ensuring oxygen is absorbed and carbon dioxide is removed during respiration. Choice A is incorrect as the kidneys, not the lungs, filter blood. Choice C is incorrect as energy production primarily occurs in cells, not in the lungs. Choice D is incorrect as waste removal, such as the excretion of carbon dioxide, is a function of the lungs, but the primary function is the exchange of gases.
