Managing High Blood Pressure Medication in Pregnancy

Practise this PLAB 2 counselling station on Hypertension in Pregnancy. 8-minute voice AI simulation with feedback on all 3 marking domains.

Clinical scenario

You are an FY2 doctor in the antenatal clinic. Mrs Priya Kapoor, a 31-year-old woman who is 9 weeks pregnant, is attending for booking appointment. She is on Ramipril 10mg for hypertension. She wants to continue the same medication but needs counselling about why ACE inhibitors are contraindicated in pregnancy and what safer alternatives are available. Please counsel her about medication safety in pregnancy, explain the risks and benefits, and discuss alternative antihypertensive options.

Background notes: PMH: Hypertension, Non-smoker, Non-drinker, Healthy BMI

What this station tests

  • Explaining teratogenicity in plain language: why ACE inhibitors are contraindicated, the difference between first and second/third trimester risk, and providing proportionate reassurance about first-trimester exposure
  • Knowledge of safe antihypertensive options in pregnancy: labetalol, nifedipine MR, methyldopa, with practical prescribing details
  • Addressing maternal guilt about inadvertent medication exposure: proportionate reassurance without dismissing or amplifying concern
  • Pre-eclampsia risk awareness: explaining that pre-existing hypertension increases risk and that low-dose aspirin from 12 weeks is recommended
  • Practical counselling for a first-time mother with a high-risk pregnancy: frequency of monitoring, growth scans, what to watch for

Consultation approach

The opening

Medication safety counselling in pregnancy requires addressing two things simultaneously: the clinical facts about teratogenicity and the emotional reality of a mother who fears she may have harmed her baby. Mrs Kapoor is 31, 9 weeks pregnant with her first baby after 2 years of trying, and on ramipril 10mg for hypertension. She has been told her medication is unsafe and has googled it. Start positively: 'Congratulations on your pregnancy, Priya. I understand there's been some concern about your blood pressure medication. Can you tell me what you've been told so far?' She will explain what the receptionist and GP said, that she googled ramipril in pregnancy, and that she now feels guilty.

Core approach

Address guilt before clinical content. She has been taking ramipril for 9 weeks and fears she has already harmed the baby. Provide proportionate reassurance: 'The highest risk from ACE inhibitors is in the second and third trimesters, when the baby's kidneys are developing. First-trimester exposure carries a much lower risk. The fact that we are changing it now, at 9 weeks, is the right time.' Do not dismiss her concern, but do not amplify it.

Explain why ACE inhibitors are contraindicated in clear language. Ramipril can affect the baby's kidney development, reduce the fluid around the baby, and affect bone growth, particularly from the second trimester onward. Explain the safe alternatives: labetalol is first-line per NICE NG133, taken two or three times daily. Nifedipine MR is second-line. Methyldopa is third-line. She will want practical details: labetalol side effects (fatigue, dizziness, cold hands, usually mild), and whether she can return to ramipril after delivery (yes, it is safe postpartum).

Explain why blood pressure control matters in pregnancy: uncontrolled hypertension increases risk of pre-eclampsia, placental abruption, and growth restriction. She is at increased risk of pre-eclampsia due to pre-existing hypertension and should start low-dose aspirin (75 to 150mg daily from 12 weeks) to reduce this risk. This is commonly missed by candidates but demonstrates current guideline knowledge.

Closing and safety netting

Summarise the plan: stop ramipril today, start labetalol today, blood pressure check in one week, low-dose aspirin from 12 weeks, closer antenatal monitoring with growth scans. Reassure her that with good BP control, the outlook for both her and the baby is very good.

Safety net with pregnancy-specific red flags: severe headache, visual disturbance, pain below the ribs on the right side, sudden swelling of face or hands, or significantly reduced baby movements later on. These could indicate pre-eclampsia. Offer written information, because she will not remember everything from an anxious consultation. Close by acknowledging her situation: 'I know this has been worrying, especially after 2 years of trying. The important thing is we have caught this and are making the right changes now.'

How examiners mark this station

Examiners will assess your ability to explain hypertension in pregnancy and its management in a patient-centred way. Domain 2 (Clinical Management) and Domain 3 (Interpersonal Skills) are equally weighted and primary. Expect marks for accurate information delivery, shared decision-making, chunk-and-check technique, and addressing the patient's specific concerns. Domain 1 (Data Gathering) is assessed through how well you establish the patient's baseline understanding and elicit their concerns.

Domain 1: Data Gathering, Technical and Assessment Skills (Supporting)

Scores well: Establishing what she has been told so far and what she found on Google. Checking her current ramipril dose and BP control. Understanding the timeline: 9 weeks, first pregnancy, 2 years trying to conceive. Identifying her emotional state (guilt, anxiety) as a priority to address.

Costs marks: Not asking what she already knows before explaining. Not checking her current BP control on ramipril. Not exploring the emotional impact of the situation.

Domain 2: Clinical Management Skills (Primary focus)

Scores well: Accurate explanation of ACE inhibitor teratogenicity with trimester-specific risk. Naming labetalol as first-line alternative with practical details. Pre-eclampsia risk counselling and aspirin recommendation. Appropriate monitoring plan: BP checks, growth scans, enhanced antenatal care. Post-pregnancy plan: can resume ramipril.

Costs marks: Inaccurate or alarmist risk information. Unable to name safe alternatives. Missing aspirin for pre-eclampsia prevention. No clear monitoring plan. Not explaining the pre-eclampsia safety netting symptoms.

Domain 3: Interpersonal Skills (Primary focus)

Scores well: Congratulating her on the pregnancy at the outset. Addressing guilt proportionately and early. Empathic acknowledgment of her anxiety after 2 years trying to conceive. Clear, jargon-free explanation. Checking understanding at each stage. Providing written information for a consultation she will struggle to remember in full.

Costs marks: Launching into teratogenicity without acknowledging her emotions. Using terms like 'oligohydramnios' or 'renal agenesis' without translation. Not acknowledging that this is her first pregnancy after 2 years of trying. Being overly clinical in a highly emotional situation.

Common examiner feedback (and how to fix it)

Did not provide adequate explanation or plan to the patient

Fix: Use chunk-and-check: deliver one concept, check understanding, then move to the next. Offer all relevant treatment options with risks and benefits before helping the patient decide.

Did not sufficiently recognise or respond to the patient's feelings, concerns, or expectations

Fix: Before and during counselling, explicitly ask what concerns the patient most. Respond to emotional cues with empathic statements before continuing with information.

Common mistakes in this station

  1. Amplifying guilt about first-trimester exposure. Mrs Kapoor is already anxious and has been googling 'ramipril in pregnancy.' Candidates who overstate the first-trimester risk or say 'the baby may have been harmed' cause unnecessary distress. The risk is real but lower in the first trimester, and switching at 9 weeks is timely.
  2. Not knowing the safe alternatives. Candidates must be able to name labetalol as first-line. Saying 'we will switch you to something safe' without being able to specify what is a Domain 2 failure.
  3. Forgetting low-dose aspirin for pre-eclampsia prevention. NICE NG133 recommends 75 to 150mg aspirin daily from 12 weeks for women with pre-existing hypertension. This is a commonly missed point that demonstrates current guideline knowledge.

Resitting PLAB 2?

If counselling stations have been a challenge, the most common issue is information overload: delivering too much clinical detail without checking understanding. Practise the chunk-and-check technique until it becomes automatic. Remember that shared decision-making, not lecturing, is what scores highly in Domain 3.

Example opening

Hello, my name is Dr [Name]. I understand you've come in today to discuss [topic]. Before I explain things, could you tell me what you've been told so far, so I know where to start?

Frequently asked questions

What is the best way to structure this hypertension in pregnancy counselling consultation?

Medication safety counselling in pregnancy requires addressing two things simultaneously: the clinical facts about teratogenicity and the emotional reality of a mother who fears she may have harmed her baby. Mrs Kapoor is 31, 9 weeks pregnant with her first baby after 2 years of trying, and on ramipril 10mg for hypertension. She has been told her medication is unsafe and has googled it.

Where are marks won and lost in this hypertension in pregnancy station?

Examiners reward: Establishing what she has been told so far and what she found on Google. Checking her current ramipril dose and BP control. Candidates are penalised for: Not asking what she already knows before explaining. Not checking her current BP control on ramipril. Not exploring the emotional impact of the situation.

Where do candidates most often go wrong in this station?

Amplifying guilt about first-trimester exposure. Mrs Kapoor is already anxious and has been googling 'ramipril in pregnancy.' Candidates who overstate the first-trimester risk or say 'the baby may have been harmed' cause unnecessary distress. The risk is real but lower in the first trimester, and switching at 9 weeks is timely.

Can I do well in this station without real-world experience of hypertension in pregnancy?

Structure beats experience here. Focus on knowledge of safe antihypertensive options in pregnancy: labetalol, nifedipine MR, methyldopa, with practical prescribing details. Use the domain breakdown on this page to target your preparation, then practise the station aloud so your structure survives exam pressure.
