1. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

2. The nutrient facts panel was established by the USDA and the FDA to improve health and well-being by enhancing nutritional knowledge. Nutrient content claims describe a relationship between a food or food component and reduced risk of a disease or health-related condition.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: C

Rationale: The correct answer is C. The first statement is true as the nutrient facts panel was indeed established by the USDA and the FDA to improve health and well-being by enhancing nutritional knowledge. However, the second statement is false. Nutrient content claims actually refer to the amount of a nutrient in a food, not to the relationship between a food and disease risk. Therefore, the second statement is incorrect, making choice C the correct option. Choice A is incorrect because the second statement is false. Choice B is incorrect as the first statement is true. Choice D is incorrect because the second statement is false.

3. How many diet-related major risk factors for coronary heart disease does Mrs. Winslow have?

• A. 1
• B. 4
• C. 2
• D. 3

Correct answer: B

Rationale: Mrs. Winslow has four major diet-related risk factors for coronary heart disease: high total cholesterol, high LDL cholesterol, high triglycerides, and low HDL cholesterol. Choice A is incorrect because there are more than one risk factor present. Choices C and D are incorrect as they do not account for the total number of diet-related major risk factors identified.

4. When can a patient's medical record become a potential issue for the doctor or nurse?

• A. When the record is extensive
• B. When a medical record is subpoenaed in court
• C. When it is missing
• D. When the medical record is inaccurate, incomplete, or inadequate

Correct answer: D

Rationale: The correct answer is D. A medical record becomes a potential issue for a doctor or a nurse when it is inaccurate, incomplete, or inadequate. This is because a medical record is a key tool for healthcare professionals to track a patient's history, treatment, and progress. If the record is not accurate or complete, it can lead to misdiagnosis, incorrect treatment, or other potential problems in patient care. While missing records (Choice C) could be a problem, they do not directly implicate the doctor or nurse in the same way that inaccurate or inadequate records do. An extensive record (Choice A) or a record being subpoenaed in court (Choice B) are not inherently problematic for healthcare professionals and do not necessarily reflect negatively on their work.

5. Where is Vitamin K synthesized?

• A. by bacteria in the GI tract
• B. by the body by sunlight
• C. deficiency is called beriberi
• D. found in vegetable oils

Correct answer: A

Rationale: Vitamin K is synthesized by bacteria in the gastrointestinal tract. Choice B is incorrect as the synthesis of Vitamin D, not K, can be induced by sunlight exposure. Choice C is incorrect as beriberi is a condition caused by thiamine (Vitamin B1) deficiency, not Vitamin K. Choice D is incorrect as Vitamin E is commonly found in vegetable oils, not Vitamin K.
