A nurse is caring for a client who is at 36 weeks of gestation and has suspected placenta previa. For which of the following findings should the nurse monitor the client?

Choice A reason:
Initiating epidural anesthesia too soon may delay rupture of fetal membranes. This statement is not accurate. Epidural anesthesia itself does not have a direct impact on the rupture of fetal membranes. The timing of rupturing membranes is determined based on the progress of labor and other clinical indications. There is no causal relationship between epidural anesthesia and the timing of membrane rupture.

Choice B reason:
Initiating epidural anesthesia too soon can prolong labor. This statement is correct. Epidural anesthesia, while providing pain relief during labor, can also cause some degree of motor blockage and decrease the woman's ability to push effectively. This can potentially lead to a lengthening of the labor process. It is generally recommended to wait until a good labor pattern has been established to avoid unnecessary prolongation of labor.

Choice C reason:
Initiating epidural anesthesia too soon can cause fetal depression. This statement is not entirely accurate. Epidural anesthesia can cross the placenta and reach the fetus, but the effect on the baby is usually minimal. However, fetal monitoring is essential during labor to ensure the baby's well-being, regardless of whether epidural anesthesia is used or not.

Choice D reason:
Initiating epidural anesthesia too soon can cause maternal hypertension. This statement is not supported by evidence. Epidural anesthesia does not typically cause maternal hypertension. It can, however, lead to a decrease in blood pressure in some cases, which is why careful monitoring of maternal blood pressure is necessary during and after the administration of epidural anesthesia.

Choice A rationale:
0.25 mL - The nurse should not administer 0.25 mL because the available concentration of vitamin K injection is 1 mg/0.5 mL. To achieve the prescribed dose of 1 mg, administering only 0.25 mL would be insufficient.
Choice B rationale:
0.5 mL - This is the correct choice. The nurse should administer 0.5 mL of the vitamin K injection to deliver 1 mg of vitamin K, as the concentration of the injection is 1 mg/0.5 mL. By giving the full 0.5 mL, the newborn will receive the appropriate 1 mg dose.
Choice C rationale:
0.75 mL - Administering 0.75 mL would be excessive for the prescribed 1 mg dose of vitamin K. It is unnecessary to give a higher volume than required, as it could lead to potential adverse effects or wastage.
Choice D rationale:
1 mL - Similarly, administering the entire 1 mL of the vitamin K injection would result in doubling the prescribed dose, leading to potential overdose and adverse reactions. The nurse should avoid administering more than the necessary 0.5 mL.
