A nurse is caring for a client who is experiencing preterm labor and has a new prescription for terbutaline. Which of the following findings is a contraindication for the administration of this medication?
Heart disease.
Cervical dilation of 2 cm.
Gestational age of 34 weeks.
Allergy to penicillin.
The Correct Answer is A
Choice A rationale:
Terbutaline is a medication commonly used to stop preterm labor by relaxing the uterine muscles. However, it is contraindicated in clients with heart disease or certain cardiac conditions, as it can cause cardiovascular side effects such as increased heart rate, palpitations, and potential arrhythmias.
Choice B rationale:
Cervical dilation of 2 cm is a typical sign of preterm labor, and the prescription for terbutaline is appropriate to prevent further cervical dilation and delay delivery.
Choice C rationale:
A gestational age of 34 weeks indicates preterm labor, which is precisely the scenario where terbutaline would be administered to halt labor progression and extend the pregnancy.
Choice D rationale:
Allergy to penicillin is unrelated to the administration of terbutaline, as they are different medications with distinct mechanisms of action and side effects.

Correct Answer is A
Explanation
Choice A rationale:
Hormonal changes play a significant role in postpartum depression. After childbirth, there is a rapid decline in estrogen and progesterone levels, which can lead to mood fluctuations and depressive symptoms. Understanding this hormonal aspect is crucial for the nurse to address postpartum depression risk factors.
Choice B rationale:
Increased social support systems would be considered a protective factor against postpartum depression rather than a risk factor. Having strong social support can help mitigate the risk of developing postpartum depression.
Choice C rationale:
High self-esteem is not typically a risk factor for postpartum depression. In fact, individuals with higher self-esteem may be more resilient in coping with the challenges of postpartum period.
Choice D rationale:
Being a mother of two other children is not inherently a risk factor for postpartum depression. While having multiple children can be demanding, it does not directly increase the risk of developing postpartum depression. The hormonal changes and individual circumstances play more significant roles.
Correct Answer is B
Explanation
Choice A rationale:
In Rh incompatibility, if the mother's blood does not contain the Rh factor (Rh-negative) and she is exposed to Rh-positive blood (usually from the fetus during delivery), her immune system may produce anti-Rh antibodies. However, these antibodies do not typically cross the placental barrier during the first pregnancy. Rh incompatibility occurs when the mother's blood is Rh- negative, and she is carrying an Rh-positive fetus during her second or subsequent pregnancies, leading to sensitization and potential hemolysis in future pregnancies.
Choice B rationale:
This choice is correct. Rh incompatibility occurs when the mother is Rh-negative, and the newborn is Rh-positive. During the first pregnancy, the mother is not sensitized to the Rh factor and does not produce significant amounts of anti-Rh antibodies. However, if the fetus is Rh- positive, there is a risk of sensitization during childbirth or any other event where maternal and fetal blood may mix. In subsequent pregnancies, if the mother becomes pregnant with another Rh-positive fetus, her immune system will recognize the Rh antigen as foreign and produce antibodies that can cross the placenta and attack the fetal red blood cells, leading to hemolysis and hyperbilirubinemia in the newborn.
Choice C rationale:
This choice is not related to the mechanism of Rh incompatibility. Receiving a transfusion with Rh-negative blood would not cause the mother's immune system to produce anti-Rh antibodies or lead to Rh incompatibility with her newborn.
Choice D rationale:
This choice describes the ABO blood group system, not the Rh factor. ABO incompatibility can occur when a mother with blood type O (producing anti-A and anti-B antibodies) has a newborn with blood type A, B, or AB, leading to hemolysis of the fetal red blood cells. However, the question specifically mentions Rh incompatibility, which involves the Rh factor, not the ABO system.
