A pregnant woman with painless bright red vaginal bleeding is diagnosed with complete placenta previa on ultrasound. Which doctor's order should the nurse question immediately?

1. A

   Ultrasound abdomen (USG)

2. B

   Continuous fetal heart rate monitoring

3. C

   Per vaginal (PV) examination

4. D

   Preparation for emergency cesarean section

Explanation

Listen in Hindi

• Placenta previa is a condition where the placenta implants in the lower uterine segment, covering the internal cervical os.
• The classic symptom is painless, bright-red vaginal bleeding in the second or third trimester.
• A per vaginal (PV) or digital cervical examination is absolutely contraindicated in this condition.
• The examining finger can easily puncture the highly vascular placenta, which is located over the cervix.
• This can provoke sudden, massive, and life-threatening hemorrhage, jeopardizing the lives of both the mother and the fetus.

Why Other Options Were Wrong

• Option A: An ultrasound is the primary, non-invasive, and safest method to diagnose and confirm the location of the placenta. It is a necessary and appropriate order.
• Option B: Continuous fetal heart rate monitoring is crucial for assessing fetal well-being. Bleeding from placenta previa can compromise fetal oxygenation and lead to distress, making this monitoring essential.
• Option D: A complete placenta previa necessitates a cesarean delivery. Preparing for an emergency C-section is a critical and prudent step in managing a patient with active bleeding, as hemorrhage can become life-threatening at any moment.

• Visual 2: Flowchart - A simple management algorithm for a patient presenting with painless vaginal bleeding in the third trimester, emphasizing the immediate steps: 'Do not perform a PV exam' and 'Perform an ultrasound to locate the placenta'.

Clinical Relevance

• Nursing practice connection: Use the key finding related to Management of Antepartum Hemorrhage and Placenta Previa to guide bedside assessment, documentation, and the next nursing action.
• A nurse's primary responsibility is patient safety. This includes acting as a patient advocate by questioning any order that could cause harm. Recognizing the absolute contraindication of a PV exam in placenta previa is a critical safety competency.
• This scenario underscores the importance of the 'look, don't touch' rule in cases of undiagnosed third-trimester bleeding until placenta previa has been ruled out by ultrasound.
• What if? If the patient were in a remote setting without immediate ultrasound access, a sterile speculum examination (not a digital PV exam) might be cautiously performed in an operating room with a 'double setup' (fully prepared for an immediate C-section) to visualize the cervix and rule out other bleeding sources. However, a digital exam remains absolutely contraindicated.

How to Approach the Question

• First, identify the key information in the stem: the patient has 'painless bright red vaginal bleeding' and a confirmed diagnosis of 'complete placenta previa' via ultrasound.
• Recall the pathophysiology of placenta previa: the placenta is covering the cervical opening.
• Understand the primary risk associated with this condition: disrupting the placenta can cause catastrophic hemorrhage.
• Evaluate each option based on this risk. Ask yourself, 'Could this action disrupt the placenta?'
• Ultrasound (USG) is non-invasive and diagnostic (Safe).
• Fetal monitoring is external and assesses the baby's status (Safe).

Concept Tested & Keywords

• Concept Tested: Management of Antepartum Hemorrhage and Placenta Previa
• Stem keywords: pregnant woman, painless bright red vaginal bleeding, complete placenta previa, ultrasound, question immediately
• Lead-in keywords: question immediately
• Clinical cues: The combination of 'painless bright red bleeding' and an ultrasound diagnosis of 'complete placenta previa' is the classic presentation, which points to a specific set of contraindications.
• Negative lead-in flag: false
