Correct Answer: B

Rationale: Terbutaline is a tocolytic medication that works by relaxing the uterine muscles, leading to weakened uterine contractions. This effect helps to prevent preterm labor. Therefore, the nurse should expect weakened uterine contractions in a client who has received terbutaline at 28 weeks of gestation. Choices A, C, and D are incorrect. Terbutaline administration would not directly affect the fetal heart rate, enhance fetal lung surfactant production, or cause maternal hypoglycemia.

Correct Answer: D

Rationale: Measuring leg circumferences is crucial in monitoring for changes that may indicate worsening of thrombophlebitis, such as increased swelling or redness. This assessment helps in early detection of complications and timely intervention, reducing the risk of further health problems for the client. Applying cold compresses may worsen the condition by causing vasoconstriction. Massaging the affected extremity can dislodge a clot and lead to embolism. Allowing the client to ambulate may increase the risk of clot migration.

Correct Answer: A

Rationale: The correct answer is 'Moderate lochia rubra.' On the second day postpartum, it is normal for lochia to be bright red and contain small clots, indicating moderate lochia rubra. This amount of bleeding is expected as the uterus continues to shed its lining after childbirth. Excessive lochia serosa, light lochia rubra, and scant lochia serosa do not accurately reflect the described scenario. Excessive lochia serosa is more characteristic of a later postpartum period, while light and scant lochia serosa are not consistent with the bright red color and small clots observed in this case.

Correct Answer: B

Rationale: The correct answer is B because the client needs a second varicella vaccination at the postpartum visit to ensure immunity. Option A is incorrect as it implies a future need for a second vaccination without a clear action plan. Option C is incorrect as the varicella vaccine is primarily for the client's protection, not others. Option D is not the appropriate action as waiting to be tested for immunity delays the necessary second vaccination.

Correct Answer: D

Rationale: Epstein's pearls are small pearly white nodules commonly observed on the roof of a newborn's mouth. They are considered a normal finding and typically disappear without treatment. It is essential for healthcare providers to recognize these benign nodules to differentiate them from other conditions and provide appropriate education to parents. The other choices are incorrect: A) Mongolian spots are blue or purple birthmarks commonly found on the skin; B) Milia spots are tiny white bumps on a newborn's nose and face; C) Erythema toxicum presents as a rash of flat red splotches with small bumps that can appear on a baby's skin.
