Which organ of the digestive system primarily functions in absorption?

Correct Answer: C

Rationale: The correct answer is C: small intestine. This is because the small intestine is where the majority of nutrient absorption takes place due to its large surface area and presence of villi for absorption. The stomach (A) primarily functions in digestion, not absorption. The pancreas (B) produces digestive enzymes but does not directly absorb nutrients. The gallbladder (D) stores bile produced by the liver to aid in digestion but does not participate in absorption directly.

Correct Answer: C

Rationale: The correct answer is C, stab wound to the chest. This injury is the highest priority because it poses the greatest risk to the client's life due to potential damage to vital organs and major blood vessels. Immediate intervention is crucial to prevent severe bleeding, pneumothorax, or cardiac tamponade. Treating this injury promptly can significantly increase the client's chances of survival. The other choices are incorrect because: A: An open leg fracture, while serious, does not typically pose an immediate life-threatening risk compared to a stab wound to the chest. B: An open head injury can be severe, but not all head injuries are immediately life-threatening. D: Traumatic amputation of a thumb, while traumatic and painful, is not a priority compared to injuries that directly threaten a client's life.

Correct Answer: D

Rationale: The correct answer is D: Morton's neuroma. This condition typically presents as a mass in the foot causing pain and difficulty walking. The nurse should document it as Morton's neuroma because it specifically refers to a benign growth of nerve tissue between the toes. Plantar fasciitis (A) is inflammation of the tissue on the bottom of the foot, not a mass. Hallux valgus (B) is a bunion deformity of the big toe joint. Hammertoe (C) is a deformity of the toe joints. Therefore, the correct choice is D as it aligns with the description of a mass causing difficulty walking.

Correct Answer: B

Rationale: The correct answer is B: Eggs. Eggs are considered a complete protein because they contain all nine essential amino acids required by the body. These amino acids are necessary for various bodily functions, such as muscle growth and repair. Corn (A), peanuts (C), and sunflower seeds (D) are incomplete proteins as they lack one or more essential amino acids. Therefore, eggs are the best choice for a complete protein source compared to the other options provided.

Correct Answer: A

Rationale: The correct answer is A because broccoli, oranges, and dark greens are rich in essential nutrients like vitamin C, antioxidants, and phytochemicals that boost the immune system and help prevent diseases. Broccoli contains sulforaphane, which has been shown to have anti-cancer properties. Oranges are high in vitamin C, crucial for immune function. Dark greens like spinach and kale are packed with vitamins and minerals that support overall health. Choice B is incorrect because no single food can cure many diseases. Choice C is incorrect because relying solely on vitamin pills may not provide all the necessary nutrients and benefits of whole foods. Choice D is incorrect as there is no scientific evidence supporting the concept of balancing body molecules through food.
