Treating Earlier, Choosing Carefully: A Pharmacotherapy Plan for Chronic Hypertension at 24 Weeks of Pregnancy
Pregnancy changes the prescribing rules for hypertension more than almost any other life stage. The drugs that protect the kidneys and heart outside pregnancy become harmful to the fetus, the threshold for treatment has shifted within the last few years and the choice between the two main oral agents depends on the woman's other conditions. This plan treats a composite woman with chronic hypertension at 24 weeks. It argues that she should be treated to a goal below 140/90 mm Hg, that extended-release nifedipine suits her better than labetalol and that honest counseling about her early exposure to lisinopril is part of the prescription.
Assessment
Renee is 34, in her second pregnancy, at 24 weeks. Chronic hypertension was diagnosed three years ago and controlled on lisinopril 20 mg daily. The pregnancy was unplanned; when it was confirmed at 8 weeks, the lisinopril was stopped. Her pressure fell during the second trimester, as it often does, to readings in the 120s and 130s over 80s, but over the past three weeks her home readings have averaged 148/95, and today's clinic readings are 150/96 and 146/94. She has mild intermittent asthma, using albuterol a few times a year. She takes aspirin 81 mg nightly, started at 12 weeks, and a prenatal vitamin. Her 20-week anatomy scan was normal, and fetal growth is on the 45th percentile.
Preeclampsia must be excluded before labeling this as worsening chronic hypertension. She has no headache, visual change or upper abdominal pain. Her platelet count is 228,000/mm³, creatinine 0.6 mg/dL, liver enzymes are normal and her urine protein-to-creatinine ratio is 0.12. These findings support chronic hypertension without superimposed preeclampsia at this time (American College of Obstetricians and Gynecologists [ACOG], 2019).
Why Treat Now
For years, the threshold for treating chronic hypertension in pregnancy was 160/110 mm Hg, because lowering milder elevations was thought to offer little and might restrict fetal growth (ACOG, 2019). The Chronic Hypertension and Pregnancy trial changed that. It randomized 2,408 women with mild chronic hypertension to treatment aimed at below 140/90 or to treatment only if pressure reached 160/105. The composite primary outcome, which included preeclampsia with severe features, medically indicated birth before 35 weeks, placental abruption and fetal or neonatal death, occurred in 30.2% of the treated group and 37.0% of the control group, without an increase in small-for-gestational-age infants (Tita et al., 2022). An earlier trial had already shown that tighter control reduced severe maternal hypertension without harming the baby (Magee et al., 2015). ACOG has since endorsed the lower threshold. Renee's readings are above 140/90 on several occasions, so treatment is indicated.
Drug Selection
Labetalol and extended-release nifedipine are the usual first-line oral agents, and methyldopa is an alternative (ACOG, 2019). The two first-line drugs lower pressure comparably, so the choice rests on the patient. Labetalol is a nonselective beta blocker with alpha-blocking activity; beta-2 blockade can provoke bronchospasm, and its labeling cautions against use in asthma. Nifedipine relaxes vascular smooth muscle and has no effect on the airways, although it can cause headache, flushing and ankle swelling.
Because Renee has asthma, extended-release nifedipine 30 mg once daily is the better choice. The dose can be increased to 60 mg and then 90 mg at intervals of about a week if her goal is not reached, up to 120 mg daily. She should swallow the tablet whole. Immediate-release nifedipine capsules should not be used for chronic treatment. Methyldopa remains an option if nifedipine is not tolerated, but it is a weaker agent, often needs dosing three or four times a day and commonly causes fatigue and low mood, which matter to a mother of a young child. Her aspirin should continue until 36 weeks.
The Early Lisinopril Exposure
Renee has asked whether her baby was harmed by the lisinopril she took before she knew she was pregnant. A Tennessee Medicaid cohort found a risk ratio of 2.71 for major malformations after exposure to ACE inhibitors in the first trimester alone (Cooper et al., 2006). A larger California cohort, however, found that the risk of heart defects with first-trimester ACE inhibitors was similar to that seen with other antihypertensives and with untreated hypertension, suggesting that the hypertension itself, not the drug, may explain much of the association (Li et al., 2011). The harm from exposure in the second and third trimesters, including reduced amniotic fluid and fetal kidney injury, is much better established, and her drug was stopped well before then. Her normal anatomy scan is reassuring. The honest message is that the risk is uncertain and probably small and that stopping at 8 weeks was the right step.
Monitoring and Education
Renee should check her pressure at home twice daily and bring her readings to a visit in one to two weeks. The target is below 140/90, and she should not be over-treated to very low pressures. Because nifedipine can cause headache, she needs to know which headaches are warning signs: a severe or persistent headache, visual change, pain under the right ribs or sudden swelling of the face and hands should prompt an immediate call, and a reading of 160/110 or higher is an emergency. Preeclampsia labs should be repeated if her pressure rises or symptoms appear. Serial growth ultrasounds every four weeks and antenatal fetal testing from the third trimester are standard with chronic hypertension (ACOG, 2019).
After Birth
Pressure often rises in the first week after delivery. Nifedipine can continue while she breastfeeds. If she wants a return to an ACE inhibitor for long-term protection, enalapril is generally regarded as compatible with breastfeeding, and lisinopril should not be restarted until she has a reliable contraception plan, since a future unplanned pregnancy would bring the same problem. Women with chronic hypertension in pregnancy also carry a higher long-term cardiovascular risk, so her care should move back to a primary care schedule of blood pressure, lipid and glucose checks rather than ending at the six-week visit.
Conclusion
Renee's plan follows the evidence that treating mild chronic hypertension in pregnancy prevents serious outcomes, chooses nifedipine because her asthma makes labetalol a poorer fit and treats her question about lisinopril with the honesty the evidence allows. Each decision changes because she is pregnant.

What the NUR 602 Module 5 instructions ask for
The second NUR 602 pharmacotherapy plan often places the patient in pregnancy or lactation and asks how prescribing must change. Expect to present the assessment, rule out related diagnoses, state goals, select and dose a drug with evidence, address fetal safety, set monitoring and educate the patient, usually in three to five pages of APA 7 text. Some prompts also ask about postpartum and breastfeeding. Read the case for coexisting conditions, because they often decide between two otherwise equal first-line drugs. Use current obstetric guidance and the primary trials behind it, and check that your threshold for treatment reflects the most recent evidence rather than an older textbook value you may have learned earlier.
How this NUR 602 Module 5 pharmacotherapy plan example is built
The sample follows a composite 34-year-old at 24 weeks whose lisinopril was stopped at 8 weeks and whose readings now average 148/95. It excludes preeclampsia with symptoms and labs, then uses the CHAP trial, with its 30.2% versus 37.0% primary outcome, and the CHIPS trial to justify treating toward below 140/90. Her asthma tips the choice from labetalol to extended-release nifedipine 30 mg with titration steps. A separate section weighs the Tennessee and California cohort studies on first-trimester ACE inhibitor exposure and gives her a truthful answer. Monitoring, warning signs and a breastfeeding-compatible plan after birth complete the paper, supported by five references, each one a guideline or a primary study rather than a textbook summary.
Where the NUR 602 Module 5 rubric puts the points
Rubrics for this plan usually award points for assessment and differential diagnosis, evidence-based drug selection, accurate dosing and titration, fetal and maternal safety, patient education, monitoring and APA 7 writing. In pregnancy, graders look closely at whether contraindicated drugs are identified and stopped, whether the treatment threshold is current and whether preeclampsia has been considered. Choosing between first-line agents on a stated patient factor earns more credit than naming both. Counseling that presents uncertain evidence fairly shows advanced practice judgment. A plan that looks past delivery to breastfeeding and future pregnancy often reaches the top band, because it treats the patient across her life span.
NUR 602 Module 5 help: the mistakes that cost points
Pregnancy plans lose points for citing the old 160/110 threshold, for naming labetalol and nifedipine without choosing between them, for forgetting preeclampsia labs or for leaving out the postpartum period. A subtler error is reassuring or alarming the patient about an early drug exposure without evidence. State the current threshold with its trial, choose one agent for a reason tied to the patient, write a titration plan, give clear warning signs and address breastfeeding. If your case involves diabetes, epilepsy, depression or thyroid disease in pregnancy, send the case and rubric so the same structure can be applied to that drug decision and to the trimester your patient is in.

NUR 602 Module 5 questions, answered
Where can I find a free NUR 602 Module 5 Pharmacotherapy Plan sample?
This page shows the whole plan: chronic hypertension at 24 weeks treated toward below 140/90 using the CHAP trial, nifedipine chosen over labetalol for a patient with asthma and APA 7 references.
At what blood pressure should chronic hypertension in pregnancy be treated?
After the CHAP trial, treatment is recommended when pressure is 140/90 mm Hg or higher. Treating to that goal reduced serious outcomes without increasing small-for-gestational-age births.
Is labetalol or nifedipine better in pregnancy?
Both are first-line and lower pressure similarly. The choice rests on the patient: labetalol is avoided in asthma because of beta blockade, and nifedipine can cause headache and ankle swelling.
Are ACE inhibitors safe in pregnancy?
No. They should be stopped as soon as pregnancy is known. Second and third trimester exposure can harm fetal kidneys, while the risk from early first trimester exposure is less certain.
Which blood pressure drugs can be used while breastfeeding?
Nifedipine and labetalol can usually continue, and enalapril is generally regarded as compatible with breastfeeding. Contraception planning matters before restarting any ACE inhibitor long term.
