Okay, let's tackle this question. The patient is a primigravida at 36 weeks with a complete placenta previa and heavy bleeding. The question is asking for the exception in the next steps. First, I need to recall what placenta previa is. It's when the placenta implants over the internal cervical os, which can cause painless, bright red bleeding. Complete previa means the placenta is covering the entire os.

The next steps in management would typically involve stabilizing the patient, preventing further bleeding, and preparing for delivery. Since she's at 36 weeks, the baby is likely viable, so delivery might be necessary. However, in active bleeding, a vaginal delivery isn't possible because of the placenta blocking the cervix. So a cesarean section is the standard approach.

Now, considering the options, the incorrect step would be something that's contraindicated. For example, digital cervical examination is a red flag because it can cause profuse bleeding by disrupting the placenta. So any option suggesting a vaginal exam or digital check would be wrong. Also, tocolytics might be used if there's preterm labor, but if the patient is bleeding heavily, the priority is not tocolytics but immediate delivery. Wait, but if the patient is bleeding and the fetus is in distress, maybe tocolytics are used to delay delivery for transfer or corticosteroids. Hmm, need to check.

The correct answer is the one that's not appropriate. So the options not to do would be things like digital exam, or maybe administering tocolytics if they're bleeding. Wait, in active bleeding, you don't want to do anything that could cause more bleeding. Also, if the patient is having heavy bleeding, you need to manage it with IV fluids, blood transfusion, and prepare for C-section. So the exception would be something that's contraindicated. Let me think: maybe giving magnesium sulfate for tocolysis. Or maybe digital exam. Since the question is asking for the EXCEPT, the incorrect next step, the wrong option would be the one that's contraindicated. So the answer is probably option that suggests a digital exam. Let me confirm: in placenta previa, any cervical manipulation is contraindicated. So if any option says "perform digital cervical exam", that's incorrect. So the correct answer here is the option that says to do that. Therefore, the correct answer is the one that includes a digital exam. The question is phrased as "all of the following are appropriate next steps EXCEPT", so the wrong one is the one that's not appropriate. So the correct answer is the one that's the exception.

**Core Concept**
Placenta previa, particularly the complete type, involves placental implantation over the internal cervical os, leading to painless, recurrent bleeding. Management prioritizes maternal stabilization, fetal protection, and urgent delivery via cesarean section to avoid life-threatening hemorrhage from cervical manipulation.

**Why the Correct Answer is Right**
Digital cervical examination is contraindicated in placenta previa due to the risk of precipitating massive hemorrhage by disrupting the placenta. The primary goals are to prevent further bleeding, maintain fetal viability (via steroids if needed), and prepare for emergent cesarean delivery. Immediate steps include maternal resuscitation

✓ Correct Answer: A. Administer intramuscular terbutaline
