A nurse is providing care for a patient who is 28 weeks pregnant and has received betamethasone.
The nurse recognizes that the use of betamethasone affects which of the following?

Weakened uterine contractions

Maternal blood glucose of 63 mg/dL

Decreased fetal heart rate

Enhanced production of fetal lung surfactant

Answer and Explanation

The Correct Answer is D

Choice A rationale

Betamethasone, a corticosteroid, is not known to weaken uterine contractions. It is often administered to pregnant women at risk of preterm delivery to enhance fetal lung maturation and reduce complications associated with prematurity.

Choice B rationale

Betamethasone can potentially increase blood glucose levels, not decrease them. This is particularly relevant in women with gestational diabetes, as corticosteroids can exacerbate hyperglycemia.

Choice C rationale

Betamethasone does not typically decrease the fetal heart rate. Instead, it is used to help mature the lungs of the fetus.

Choice D rationale

Betamethasone is administered to pregnant women at risk of preterm delivery to enhance the production of surfactant in the fetal lungs. Surfactant is a substance that prevents the small air sacs in the lungs from collapsing, thereby aiding in the baby’s ability to breathe after birth.

Correct Answer is A

Explanation

Choice A rationale

The rubella vaccine is a live vaccine, which means it contains a weakened version of the virus. Because the virus is still active, live vaccines are not safe for pregnant people. There is a small chance they may pass the virus to the baby. Therefore, it is recommended that adults of childbearing age should avoid getting pregnant for at least four weeks after receiving the MMR vaccine. This is to ensure the safety of both the mother and the baby.

Choice B rationale

This statement is incorrect. The rubella vaccine does not require additional shots after each baby with Rh-positive blood. The rubella vaccine is typically administered in childhood and provides long-term protection.

Choice C rationale

This statement is also incorrect. The rubella vaccine does not require additional shots in 1 month and again in 6 months. The vaccine provides long-term protection and does not typically require frequent boosters.

Choice D rationale

While it’s true that some vaccines can cause side effects such as fever and vomiting, these are not common side effects of the rubella vaccine. Therefore, this statement is not entirely accurate.

A. Return the platelet bag and tubing to the blood bank. B. Stop the infusion. C. Notify the provider. D. Collect a urine sample from the client.

Correct Answer is B

Explanation

Choice A rationale

Returning the platelet bag and tubing to the blood bank is not the immediate action to take when a client reports having lower back pain and feeling chilled and itchy during a PRBC transfusion. These symptoms could indicate a transfusion reaction, which is a serious complication that requires immediate intervention.

Choice B rationale

Stopping the infusion is the first action the nurse should take when a client reports symptoms of a transfusion reaction. This is because continuing the transfusion could worsen the reaction and potentially lead to more serious complications.

Choice C rationale

While notifying the provider is an important step in managing a transfusion reaction, it is not the first action the nurse should take. The nurse should first stop the infusion to prevent further exposure to the blood product.

Choice D rationale

Collecting a urine sample from the client is not the immediate action to take when a client reports having lower back pain and feeling chilled and itchy during a PRBC transfusion. These symptoms could indicate a transfusion reaction, which requires immediate intervention.
