Which vitamin is crucial for collagen synthesis and wound healing?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin E
- D. Vitamin K
Correct Answer: A
Rationale: The correct answer is Vitamin C. Vitamin C is crucial for collagen synthesis, a process important for wound healing. Collagen is a key protein that helps in wound repair and tissue strength. Vitamin D is primarily known for its role in calcium absorption and bone health, not directly related to collagen synthesis. Vitamin E is an antioxidant that helps protect cells from damage but is not directly involved in collagen synthesis. Vitamin K is essential for blood clotting but does not play a major role in collagen synthesis for wound healing.
What food would most likely be included in Level 1 of the National Dysphagia Diet?
- A. peanut butter
- B. oatmeal
- C. fruit preserves
- D. plain yogurt
Correct Answer: D
Rationale: The correct answer is D, plain yogurt. Level 1 of the National Dysphagia Diet includes pureed or smooth foods that are easy to swallow. Plain yogurt fits this criteria as it is smooth and can be easily consumed without posing a risk of choking. Choices A, B, and C are not typically included in Level 1 of the diet. Peanut butter, oatmeal, and fruit preserves are not usually suitable for individuals on Level 1 of the National Dysphagia Diet as they may present a choking hazard or are not in a pureed or smooth form.
What differentiates one amino acid from another?
- A. The amine group
- B. The acid group
- C. The side chain
- D. None of the above
Correct Answer: C
Rationale: The side chain, also known as the R group, is what differentiates one amino acid from another. It imparts unique properties to each amino acid, thereby influencing their roles and functions in proteins. The amine group (Choice A) and the acid group (Choice B) are components of all amino acids and do not cause the differences among various amino acids. Choice D is incorrect as it suggests that none of the given options account for the differences, which is not true as the side chain does.
What does oliguria lead to in patients with acute kidney injury?
- A. Hypophosphatemia and overgrowth of bone tissue
- B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
- C. Sodium retention and elevated levels of potassium
- D. Edema due to increased urine production
Correct Answer: C
Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.
What activities best describe the work of the placenta during pregnancy?
- A. surrounding and cushioning the fetus
- B. combining maternal and fetal blood stores to exchange nutrients
- C. producing hormones that maintain the pregnancy
- D. absorbing vitamins and minerals that can be transferred to the fetus
Correct Answer: C
Rationale: The placenta plays a crucial role in producing hormones that are necessary for maintaining pregnancy, supporting fetal development, and preparing the mother's body for childbirth. Choices A, B, and D are incorrect because the placenta's primary function is not to surround and cushion the fetus, combine blood stores for nutrient exchange, or absorb vitamins and minerals. While the placenta does facilitate the exchange of nutrients and oxygen between the mother and fetus, its hormone production is the most critical function during pregnancy.
