HESI A2 Anatomy and Physiology Practice Exam

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

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.

2. Which hormone is responsible for regulating blood sugar levels?

Correct answer: A

Rationale: Insulin, produced by the pancreas, is the hormone responsible for regulating blood sugar levels. It works by facilitating the uptake of glucose into cells, helping to lower blood sugar levels. Glucagon, on the other hand, works to increase blood sugar levels by promoting the release of glucose from the liver. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism. Melatonin, a hormone that helps regulate sleep-wake cycles, is not responsible for regulating blood sugar levels. Therefore, the correct answer is insulin.

3. Which vitamin is important for vision?

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A is crucial for maintaining healthy vision, particularly in low-light conditions. It plays a key role in the health of the retina and is necessary for the proper functioning of the eye. Deficiency in Vitamin A can lead to night blindness and other vision problems. Vitamin C is important for the immune system and skin health, not specifically for vision. Vitamin D is essential for bone health and overall well-being, but it is not directly related to vision. Vitamin K is important for blood clotting, but it is not specifically linked to vision.

4. Which structure in the kidney is responsible for filtering blood?

Correct answer: A

Rationale: The glomerulus is the correct answer. It is a vital structure in the kidney responsible for filtering blood. The glomerulus is a network of capillaries that filters waste products and excess substances from the blood to form urine. While the Bowman's capsule, Loop of Henle, and Collecting duct are also essential components of the nephron, the primary site of blood filtration occurs at the glomerulus. The Bowman's capsule surrounds the glomerulus and collects the filtered fluid, the Loop of Henle reabsorbs water and important ions, and the Collecting duct further concentrates the urine, but none of these structures are primarily responsible for filtering blood as the glomerulus is.

5. How does the endocrine system work with the reproductive system?

Correct answer: D

Rationale: The correct answer is D. The endocrine system plays a vital role in the regulation of sexual functions within the reproductive system. It produces hormones that are responsible for various functions, such as the development of secondary sex characteristics, production of gametes (sperm and egg cells), and the regulation of the menstrual cycle. These hormones are crucial for the proper functioning and coordination of the reproductive system, ensuring the successful reproduction and maintenance of reproductive health. Choices A, B, and C are incorrect because the reproductive system is not primarily responsible for transforming minerals into nutrients, determining the sex of the embryo, or controlling the growth of secondary sex organs. These functions are mainly regulated by the endocrine system in coordination with the reproductive system.
