Correct Answer: A

Rationale: Painless red vaginal bleeding is a hallmark sign of placenta previa. In this condition, the placenta partially or completely covers the cervical opening, leading to painless, bright red bleeding due to the separation of the placenta from the uterine wall. Other types of bleeding, such as those associated with abdominal pain or mucus passage, are more indicative of conditions like placental abruption rather than placenta previa. Therefore, choices B, C, and D are incorrect as they describe findings more consistent with placental abruption rather than placenta previa.

Correct Answer: D

Rationale: Variable decelerations can indicate umbilical cord compression, which is a concern that may arise due to the umbilical cord being compressed during labor. This compression can lead to reduced blood flow and oxygen delivery to the fetus, necessitating close monitoring and potentially interventions to alleviate the pressure on the cord. Early decelerations are typically benign and mirror the contractions, indicating fetal head compression. Accelerations are reassuring patterns that show a healthy response to fetal movement. Late decelerations are concerning as they suggest uteroplacental insufficiency, indicating potential oxygen deprivation to the fetus.

Correct Answer: C

Rationale: Having the client pant during contractions is crucial to prevent premature pushing, particularly when the cervix is not fully dilated. Premature pushing can lead to cervical swelling and may impede the progress of labor. It is important to allow the cervix to fully dilate before active pushing to prevent complications. Assisting the client into a comfortable position (Choice A) may not address the urge to push and can lead to premature pushing. Observing the perineum for signs of crowning (Choice B) is important but does not address the immediate need to prevent premature pushing. Helping the client to the bathroom to void (Choice D) does not address the urge to push and may not be appropriate at this stage of labor.

Correct Answer: A

Rationale: The priority nursing intervention in this situation is to palpate the client's uterine fundus. A boggy uterus that is not well contracted may indicate uterine atony, which can lead to postpartum hemorrhage. Palpating the fundus and massaging it if it is boggy helps to promote contractions and reduce bleeding, making it the most critical intervention to address the potential underlying issue. Assisting the client to a bedpan to urinate, preparing to administer oxytocic medication, or increasing the client's fluid intake are not the immediate priorities in this scenario compared to assessing and addressing the uterine fundus status.

Correct Answer: B

Rationale: Tocolytic therapy is used to suppress premature labor. It is appropriate to administer it to a client experiencing preterm labor at 26 weeks of gestation to help delay delivery and improve neonatal outcomes. Administering tocolytic therapy to a client experiencing fetal death, Braxton-Hicks contractions, or post-term pregnancy is not indicated and may not be safe or effective in these situations. Fetal death at 32 weeks indicates a non-viable pregnancy, Braxton-Hicks contractions are normal and not indicative of preterm labor, and post-term pregnancy at 42 weeks does not require tocolytic therapy.
