The nurse is teaching a group of clients in a prenatal education class.
What statement by a pregnant client indicates the need for additional teaching?

Choice A rationale

Knowing when contractions began is important for assessing the progression and duration of labor and determining the phase of labor the client is in. However, when birth is imminent, this information is secondary to assessing the integrity of the amniotic sac. Immediate risk assessment for the baby is the top priority for imminent delivery.

Choice B rationale

The estimated due date (EDD) is vital for determining fetal maturity and potential risks associated with prematurity or post-term gestation. While essential data, the EDD does not address the immediate safety and delivery logistics when birth is imminent. The most urgent question relates to current membrane status and imminent delivery risk.

Choice C rationale

Ascertaining if the membranes have ruptured is the most crucial question when delivery is imminent because it directly relates to immediate fetal risk and delivery preparation. Ruptured membranes with a presenting part not engaged increases the risk of umbilical cord prolapse, a true obstetric emergency, and also requires urgent sterile assessment and documentation of the fluid's color and time of rupture.

Choice D rationale

Parity (whether this is the first pregnancy) is significant as multiparas (those with previous pregnancies) often have faster labors and deliveries due to a more compliant cervix and uterus. While informative for estimating delivery speed, it is less critical than establishing the immediate status of the amniotic fluid and cord to ensure a safe, planned delivery.

Choice A rationale

While rare, a decreased level of consciousness (LOC) is generally associated with high spinal anesthesia, where the local anesthetic ascends to a level affecting the brainstem. Epidural anesthesia is delivered into the epidural space, and typically does not cause significant systemic absorption or central nervous system depression unless an accidental intrathecal or intravascular injection occurs.

Choice B rationale

Hypothermia is not a common or direct effect of epidural anesthesia with Bupivacaine. While chilling can occur during labor due to vasodilation-induced heat loss or fluid administration, the anesthetic itself does not characteristically induce a significant drop in core body temperature, and it is more often a result of maternal or environmental factors.

Choice C rationale

The most common and significant hemodynamic alteration is hypotension, not hypertension, caused by the peripheral vasodilation that results from the sympathetic nervous system block. This vasodilation leads to blood pooling in the lower extremities, decreasing venous return to the heart, thus lowering cardiac output and systemic blood pressure.

Choice D rationale

Urinary retention is a common and expected side effect because the local anesthetic blocks the sacral parasympathetic fibers that control bladder sensation and the detrusor muscle reflex. This sensory and motor block impairs the client's awareness of bladder fullness and the ability to voluntarily void, necessitating frequent monitoring and often catheterization.
