1. The RDA for iron is higher in premenopausal women than for men or postmenopausal women because of the blood loss during menstruation.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. The Institute of Medicine (IOM) recommends 18 mg of iron per day for women 19 to 50 years old, 8 mg/day for women 51 years old and older, and men 19 years old and older. During menstruation, women lose blood containing iron, leading to a higher iron requirement in premenopausal women compared to men or postmenopausal women. This increased demand aims to replenish the iron lost during this physiological process. Therefore, the statement and reason are directly linked, explaining why the RDA for iron is higher in premenopausal women than in men or postmenopausal women. Choices B, C, and D are incorrect as they do not accurately assess the relationship between the statement and the reason provided in the question.

2. What is the process of formal negotiations of working conditions between a group of registered nurses and employer?

• A. grievance
• B. arbitration
• C. collective bargaining
• D. strike

Correct answer: C

Rationale: The correct answer is 'collective bargaining.' Collective bargaining involves negotiations between a group of employees, in this case, registered nurses, and their employer to determine working conditions, wages, benefits, and other aspects of employment. Grievance refers to a formal complaint about a workplace issue, arbitration involves a neutral third party making a decision in a dispute, and a strike is a work stoppage by employees to protest against their employer.

3. Which of the following is the least likely reason that osteoporosis is more prevalent in women?

• A. women have smaller bodies
• B. women have lower bone mass
• C. women consume less calcium
• D. bone loss begins later in women

Correct answer: D

Rationale: The correct answer is D. Contrary to the statement, bone loss begins earlier in women, particularly after menopause, due to the decrease in estrogen levels. This drop in estrogen accelerates bone loss, contributing to the higher prevalence of osteoporosis in women. Choices A, B, and C are more likely reasons for the increased prevalence of osteoporosis in women. Women generally have smaller bodies, lower bone mass compared to men, and may consume less calcium, all of which are significant factors contributing to the higher incidence of osteoporosis in women.

4. 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.

5. Select all that apply. Which of the following oils contain high levels of unsaturated fatty acids and low levels of saturated and trans fats?

• A. vegetable oil
• B. palm oil
• C. coconut oil
• D. canola oil

Correct answer: A

Rationale: Vegetable, canola, and olive oils are high in unsaturated fats and low in saturated and trans fats, making them heart-healthy choices.
