The diagnosis of pregnancy is based on which positive signs of pregnancy? (Select all that apply.)

The correct answer is choice B. Hypoglycemia.Hypoglycemia is a condition where the blood sugar level is too low, which can affect the brain function and cause symptoms such as jitteriness, poor feeding, and seizures.Hypoglycemia is common in newborns, especially in preterm, small for gestational age, and infants of diabetic mothers.

Choice A is wrong because hyperglycemia is a condition where the blood sugar level is too high, which can cause dehydration, increased urination, and ketoacidosis.Hyperglycemia does not usually cause seizures in newborns.

Choice C is wrong because hypertension is a condition where the blood pressure is too high, which can cause damage to the blood vessels and organs.Hypertension can cause seizures in older children and adults, but it is rare in newborns.

Choice D is wrong because hypocalcemia is a condition where the calcium level in the blood is too low, which can affect the nerve and muscle function and cause symptoms such as twitching, spasms, and tetany.Hypocalcemia can also cause seizures in newborns, but it is less common than hypoglycemia.

I will need to increase my protein intake by 25 g per day while I am pregnant.” Protein is essential for the growth and development of the fetus and the placenta, as well as for the increased blood volume and maternal tissues.

The recommended dietary allowance (RDA) for protein during pregnancy is 71 g per day, which is 25 g more than the RDA for non-pregnant women.

Choice B is wrong because the calcium intake does not need to increase during lactation.

The RDA for calcium for lactating women is the same as for non-lactating women, which is 1000 mg per day for women aged 19 to 50 years.

Calcium absorption and retention are enhanced during lactation, and bone loss that may occur is usually reversible after weaning.

Choice C is wrong because the calorie intake does not need to increase by 500 kcal per day during the third trimester.

The estimated energy requirement (EER) for pregnant women increases by 340 kcal per day in the second trimester and by 452 kcal per day in the third trimester.

However, these values may vary depending on the pre-pregnancy weight, activity level, and rate of weight gain of the individual woman.

Choice D is wrong because the iron intake needs to increase by more than 10 mg per day while pregnant.

The RDA for iron during pregnancy is 27 mg per day, which is 9 mg more than the RDA for non-pregnant women.

However, this amount may not be enough to prevent iron deficiency anemia in some pregnant women, especially those who start pregnancy with low iron stores or have high iron losses due to bleeding or multiple pregnancies.

Therefore, iron supplements are often recommended for pregnant women, especially in the second and third trimesters.
