A nurse measures a client's weight as 70 kg and height as 1.1 m. What is the client's body mass index? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: BMI of 18.5 is at the lower end of the normal range (18.5-24.9), but it does not indicate severe malnutrition.

Choice B reason: Potassium 3.7 mEq/L is within the normal range (3.5-5.0), and it does not indicate electrolyte imbalance due to malnutrition.

Choice C reason: Phosphorus 3.5 mg/dL is within the normal range (2.5-4.5), and it does not indicate mineral deficiency due to malnutrition.

Choice D reason: Albumin 2.5 g/dL is below the normal range (3.5-5.0), and it indicates protein deficiency due to malnutrition. Albumin is a major protein in blood plasma that helps maintain fluid balance, transport hormones, and fight infections. Low albumin levels can cause edema, weakness, infection, and poor wound healing.

Choice A reason: Soaking fruits in water before peeling them is not a good practice for retaining nutrients because it can cause water-soluble vitamins, such as vitamin C and B-complex vitamins, to leach out into the water. It is better to wash fruits briefly under running water and peel them as thinly as possible.

Choice B reason: Cooking vegetables for the week and reheating them at each meal is not a good practice for retaining nutrients because it can cause nutrient losses due to exposure to heat, light, air, and water. It is better to cook vegetables as close to the time of consumption as possible and use minimal water and cooking time.

Choice C reason: Boiling vegetables on the stove until they are soft is not a good practice for retaining nutrients because it can cause significant nutrient losses due to high temperature and long cooking time. It is better to steam, microwave, or stir-fry vegetables until they are crisp-tender and retain their color and texture.

Choice D reason: Keeping ripe fruits refrigerated until eating them is a good practice for retaining nutrients because it can slow down the ripening process and prevent spoilage. Refrigeration can preserve the freshness, flavor, and nutritional value of fruits. However, some fruits, such as bananas, tomatoes, and avocados, should not be refrigerated because they can lose their quality and taste.
