Rationale: The CDC recommends that women who are not up-to-date with the MMR (measles, mumps, rubella) vaccine should receive it immediately postpartum. Rubella, also known as German measles, is particularly important during pregnancy because contracting rubella during pregnancy can lead to serious complications in the baby, such as birth defects and miscarriage. By ensuring the client receives the MMR vaccine postpartum, it helps protect both the mother and any future pregnancies from the risk of rubella infection.

Correct Answer: C

Rationale: Terbutaline is a beta-adrenergic agonist that is commonly used to suppress preterm labor by relaxing the uterine smooth muscle. Adverse effects of terbutaline can include respiratory distress or dyspnea, which is a serious concern and should be reported to the healthcare provider immediately. Both the nurse and the client should be alert for signs of difficulty breathing, such as shortness of breath or chest tightness, as these symptoms could indicate a potential serious reaction to the medication. Headaches, nervousness, and tremors are common side effects of terbutaline that are less concerning and may not require immediate provider notification unless they become severe or persistent.
