Which of the following statements by a client who is at 8 weeks of gestation and is Rh-negative indicates an understanding of the teaching about the Rho(D) immune globulin injection?
I will need this injection if I have a miscarriage.
I will need this injection when I am 12 weeks pregnant.
I will need this injection to prevent preterm labor.
I will need this injection after delivery if my baby is Rh-negative.
The Correct Answer is A
Choice A reason: Rho(D) immune globulin is administered after a miscarriage in Rh-negative women to prevent isoimmunization, as fetal blood mixing can occur. This immunoglobulin neutralizes Rh-positive fetal antigens, preventing maternal antibody formation that could affect future pregnancies. The immune response could otherwise lead to hemolytic disease in subsequent Rh-positive fetuses.
Choice B reason: Administering Rho(D) immune globulin at 12 weeks is not standard practice. It is typically given at 28 weeks and post-delivery or after events like miscarriage. Early administration is unnecessary unless a sensitizing event occurs, as maternal-fetal blood mixing is rare before the third trimester, per immunological principles.
Choice C reason: Rho(D) immune globulin does not prevent preterm labor, which is driven by uterine or hormonal factors. The injection targets Rh isoimmunization by neutralizing Rh-positive fetal antigens. Preterm labor involves prostaglandin and oxytocin pathways, unrelated to Rh sensitization, making this statement irrelevant to the immunoglobulin’s immunological mechanism.
Choice D reason: Rho(D) immune globulin is unnecessary post-delivery if the baby is Rh-negative, as no sensitization occurs without Rh-positive fetal blood. The injection is given only if the baby is Rh-positive to prevent maternal antibody formation. This statement reflects a misunderstanding of Rh immunology and isoimmunization risk in pregnancy.

Correct Answer is C
Explanation
Choice A reason: Polyuria is not an adverse effect of epidural analgesia. Epidurals may cause urinary retention due to bladder sensation loss from nerve blockade, not increased urine output. Polyuria could reflect unrelated conditions like diabetes insipidus, but it does not align with epidural’s neurological effects on bladder function.
Choice B reason: A maternal temperature of 37.4°C (99.4°F) is within normal range and not an adverse effect of epidural analgesia. Epidurals may rarely cause fever due to immune responses, but this temperature is physiological. It does not indicate a complication requiring documentation, per obstetric monitoring standards.
Choice C reason: Hypotension is a common adverse effect of epidural analgesia, as sympathetic blockade causes vasodilation, reducing blood pressure. This can impair placental perfusion, risking fetal hypoxia. Documentation is critical to prompt interventions like fluid boluses, ensuring maternal and fetal stability, per epidural pharmacology and obstetric care protocols.
Choice D reason: A fetal heart rate of 152/min is within the normal range (110-160/min) and not an adverse effect of epidural analgesia. While epidurals may cause maternal hypotension affecting fetal perfusion, this rate indicates fetal well-being, not requiring documentation as an adverse effect, per fetal monitoring guidelines.
Correct Answer is C
Explanation
Choice A reason: Postterm birth, beyond 42 weeks, increases risks like fetal distress or meconium aspiration but is not a direct risk factor for postpartum depression. Psychological stressors, not gestational duration, primarily drive depression. Hormonal changes and stress are key contributors, and postterm birth lacks a direct neurochemical or psychosocial link to depression.
Choice B reason: Middle-class family income is not a specific risk factor for postpartum depression. Socioeconomic status may influence access to care, but depression is more closely tied to hormonal, psychological, and social stressors. Income alone does not directly alter neuroendocrine pathways or psychosocial dynamics that contribute to postpartum depression risk in pregnant clients.
Choice C reason: Unplanned pregnancy is a significant risk factor for postpartum depression, as it increases psychological stress and anxiety. Stress hormones like cortisol can exacerbate mood dysregulation, and lack of preparedness may strain coping mechanisms. This psychosocial stressor disrupts emotional stability, increasing the likelihood of depressive symptoms in the postpartum period.
Choice D reason: Working full-time outside the home is not a direct risk factor for postpartum depression. While work-life balance may contribute to stress, it lacks a specific neurochemical or psychosocial link to depression compared to factors like unplanned pregnancy. Hormonal and emotional stressors are stronger predictors of postpartum mood disorders.
