Part 1. Peggy is a 68-year-old woman who has worked long hours indoors her entire life. A recent checkup indicated that she was severely deficient in vitamin D due to inadequate intake and a lack of sun exposure. Following these findings, the doctor diagnosed Peggy with a (1) primary deficiency of vitamin D, resulting in (2) osteomalacia or poor bone mineralization. Her doctor explained that because of this vitamin deficiency, Peggy was not able to maintain appropriate levels of calcium, which had resulted in hyperparathyroidism. In this example, hyperparathyroidism (3) is a vitamin D deficiency disease. answer choices to fill in the blank: 1. (A) primary or (B) secondary 2. (A) rickets or (B) osteomalacia 3. (A) is or (B) is not Part 2. In order for the synthesis of vitamin D to occur, a series of steps are necessary and any disruption in this process can result in a deficiency of vitamin D. With this in mind, choose the situations or conditions that could contribute to a vitamin D deficiency. Choose all that apply. (a) Living in a region without a lot of sunlight (b) Having a lighter skin pigmentation (c) Limited or no use of sunscreen outdoors (d) Having liver disease

During "feasting", the priority (or first response) of the body is to convert excess carbohydrate to: Question 1 options: Glycogen Fat Amino acids Brain food In a 2-3 hour fast, the body will be using which of the following sources to create energy? (Select all that apply). Select 3 correct answer(s) Question 2 options: Amino Acid pool Liver glycogen Muscle glycogen Fat stores Body protein (muscle and tissue) You are doing research in an impoverished region where the community survives mostly on locally grown foods, consumes white rice as a dietary staple, and mostly consumes a vegetarian diet because access to animal products is limited. When surveying the population's health status, you notice many are very thin and frail; and when talking to a member of the community, he tells you he has been experiencing tingling in his arms and hands, pain in his calves, and has recently experienced loss of appetite. When he walks away, you notice he has very poor coordination and difficulty walking. What nutrient deficiency is this community member likely experiencing? Question 3 options: Niacin (B3) Potassium Thiamin (B1) Vitamin B6 What change(s) in diet would be the best to reverse the symptoms this community member is experiencing? Select all that apply. Question 4 options: Substitute whole grain brown rice instead of white rice Increase meat consumption, especially pork Increase fruit and vegetable consumption Soak any corn products in an acidic solution During a study abroad trip to a remote village, you play with a few of the local children. During an evening game of tag, one of the boys trips over a rock—he tells you it’s because he couldn’t see it and has difficulty seeing much at night. Glancing at his eyes, you notice they seem to be dry and that there are small dry blotches on the whites of his eyes. As he stands up, you notice he is much smaller than the other children his age. What vitamin/mineral deficiency is this boy likely experiencing?
