The nurse instructs a class of postpartum women on methods to avoid nipple soreness while breastfeeding.
Which comment by a class participant indicates the need for further instruction?

The correct answer is choice B. Insulin amount needs will continue to increase throughout the second and third trimesters.This is because gestational diabetes is a form of diabetes that develops during pregnancy, usually during the 2nd or 3rd trimester.It is caused by hormonal changes that interfere with the action of insulin, leading to high blood sugar levels.As the pregnancy progresses, the placenta produces more hormones that increase insulin resistance, so the mother needs more insulin to keep her blood sugar within normal range.

Choice A is wrong because insulin amount needs will not remain stable during the third trimester.They will increase as the placenta grows and produces more hormones that cause insulin resistance.

Choice C is wrong because insulin amount needs will not decrease during the third trimester.They will increase as the placenta grows and produces more hormones that cause insulin resistance.

Choice D is wrong because insulin amount needs will not remain stable for the rest of the second and during the third trimesters.They will increase as the pregnancy progresses and the placenta produces more hormones that increase insulin resistance.

Normal ranges for blood sugar during pregnancy are: fasting < 95 mg/dL, 1 hour after meal < 140 mg/dL, 2 hours after meal < 120 mg/dL.

Rubella immunization should be given in the early postpartum period.This is because rubella infection during pregnancy can cause serious birth defects or miscarriage, and rubella vaccine is contraindicated during pregnancy.Therefore, the best time to vaccinate a woman who is not immune to rubella is after she delivers her baby.

Choice B is wrong because gamma globulin is not effective for preventing rubella infection or congenital rubella syndrome (CRS).Gamma globulin is a preparation of antibodies that can provide temporary protection against some infections, but it does not induce lasting immunity.

Choice C is wrong because gamma globulin should not be given at the next visit for the same reason as choice B.Moreover, gamma globulin can interfere with the response to live vaccines such as rubella vaccine, so it should not be given within 3 months before or after vaccination.

Choice D is wrong because rubella immunization should not be given at the next visit or during pregnancy, as it can pose a risk to the fetus.Rubella vaccine is a live attenuated virus vaccine that can cross the placenta and infect the fetus.The risk of CRS from vaccination during pregnancy is low, but it cannot be ruled out completely.Therefore, women who receive rubella vaccine should avoid pregnancy for at least 4 weeks after vaccination.
