A nurse is teaching a group of clients about dietary needs to prevent osteoporosis. Which of the following dietary choices should the nurse recommend as having the highest calcium content?

Choice A reason: Abdominal obesity is a risk factor for developing diabetes mellitus. Abdominal obesity, also known as central obesity or visceral fat, is the accumulation of fat around the abdomen and organs. Abdominal obesity can cause insulin resistance, inflammation, and metabolic syndrome, which are all associated with diabetes.

Choice B reason: Elevated HDL level is not a risk factor for developing diabetes mellitus. HDL stands for high-density lipoprotein, which is a type of cholesterol that carries excess cholesterol from the tissues to the liver for disposal. HDL is also known as "good" cholesterol, as it helps protect against heart disease and stroke. A high HDL level is desirable and beneficial for health.

Choice C reason: History of hypotension is not a risk factor for developing diabetes mellitus. Hypotension means low blood pressure, which is usually defined as less than 90/60 mm Hg. Hypotension can cause symptoms such as dizziness, fainting, fatigue, and blurred vision. Hypotension can be caused by dehydration, blood loss, medication side effects, or other conditions.

Choice D reason: History of hyperthyroidism is not a risk factor for developing diabetes mellitus. Hyperthyroidism means overactive thyroid gland, which produces too much thyroid hormone. Thyroid hormone regulates metabolism, growth, and development. Hyperthyroidism can cause symptoms such as weight loss, nervousness, palpitations, heat intolerance, and insomnia. Hyperthyroidism can be caused by Graves' disease, thyroid nodules, or thyroiditis.

Choice A reason: Serum creatinine 3.5 mg/dL is high and indicates the need for further assessment. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. High creatinine levels can indicate kidney damage or impaired renal function.

Choice B reason: Hematocrit 45% is within the normal range (37-47% for women, 40-50% for men), and it does not indicate the need for further assessment. Hematocrit is the percentage of red blood cells in the blood. Low hematocrit levels can indicate anemia, bleeding, or hemolysis.

Choice C reason: Blood urea nitrogen 18 mg/dL is within the normal range (7-20), and it does not indicate the need for further assessment. Blood urea nitrogen is a waste product of protein metabolism that is filtered by the kidneys. High blood urea nitrogen levels can indicate dehydration, kidney damage, or high protein intake.

Choice D reason: Sodium 140 mEq/L is within the normal range (135-145), and it does not indicate the need for further assessment. Sodium is an electrolyte that helps maintain fluid balance, blood pressure, and nerve impulses. Low or high sodium levels can cause confusion, seizures, or coma.
