preeclampsia - Nursing Case Study
Pathophysiology
• Primary mechanism: Preeclampsia begins with abnormal placentation, where the blood vessels in the placenta fail to remodel properly, leading to reduced blood flow to the placenta and causing placental ischemia.
• Secondary mechanism: The ischemic placenta releases factors into the mother's circulation, causing widespread endothelial dysfunction. This results in high blood pressure and damage to blood vessel linings throughout the body.
• Key complication: Endothelial dysfunction can lead to increased vascular permeability and organ damage, contributing to symptoms such as proteinuria, swelling, and in severe cases, organ failure.

Section 1
Initial Assessment Findings:
Upon admission to the maternity ward, the nurse conducts a comprehensive assessment to further evaluate the patient's condition. The nurse notes that the patient, a 28-year-old school teacher at 28 weeks of gestation, appears slightly flushed and reports a persistent mild headache that rates as a 3 out of 10 on the pain scale. The patient is alert and oriented, with no signs of acute distress. On physical examination, slight pitting edema is observed in the patient's feet and ankles, which is consistent with her initial complaint. Her blood pressure remains elevated at 140/90 mmHg, and there is trace proteinuria detected during a routine urinalysis, indicating early signs of kidney involvement. Other vital signs, including heart rate, respiratory rate, and temperature, are within normal limits.
The nurse also performs a fetal assessment, noting that the fetal heart rate is regular at 145 beats per minute, with normal variability and occasional accelerations, suggesting a reassuring fetal status. The fundal height is appropriate for gestational age, and the patient reports regular fetal movements. Given these findings, the nurse recognizes the importance of closely monitoring the patient's blood pressure and proteinuria levels to detect any progression of preeclampsia. The nurse educates the patient on the importance of resting, reducing stress, maintaining hydration, and adhering to follow-up appointments.
The healthcare team decides to initiate a plan of care that includes regular blood pressure monitoring, fetal surveillance, and dietary modifications to manage the patient's condition proactively. The patient is advised to keep a daily log of her blood pressure readings and any symptoms of concern, such as increased swelling, visual disturbances, or worsening headaches, and to report them to her healthcare provider promptly. The team plans to reassess the patient in a week to determine if further interventions or adjustments to the care plan are necessary, ensuring both maternal and fetal well-being.

One week later, the patient returns for her scheduled follow-up appointment. The nurse begins with a review of the patient's daily blood pressure log and notes that her readings have consistently remained in the range of 135-145/85-90 mmHg, indicating stable but persistently elevated blood pressure. The patient mentions that her headaches have slightly increased in frequency but remain mild, and she has experienced no visual disturbances or significant changes in swelling. She has diligently maintained her hydration and rest as advised, and reports feeling more at ease after implementing stress-reducing techniques.
During the physical assessment, the nurse observes that the slight pitting edema in the patient's feet and ankles has not worsened, and there are no new areas of swelling. A repeat urinalysis shows proteinuria remains at a trace level, suggesting no significant change in renal involvement. Vital signs are rechecked, and the patient's heart rate, respiratory rate, and temperature are still within normal limits, providing reassurance of her overall stable condition. The fetal assessment is repeated, and the fetal heart rate remains regular at 144 beats per minute, with good variability and continued occasional accelerations. The patient continues to report regular fetal movements, and the fundal height remains appropriate for 29 weeks of gestation.
Based on these findings, the healthcare team decides to continue with the current plan of care, emphasizing the importance of ongoing monitoring and adherence to lifestyle modifications. The patient is encouraged to persist with tracking her blood pressure and any symptoms, and to maintain regular prenatal appointments for close surveillance. The team plans to reassess the patient's condition in another week, prepared to make adjustments to the care plan if necessary, to ensure ongoing maternal and fetal health. This careful monitoring aims to prevent any progression of preeclampsia while supporting the patient through the remainder of her pregnancy.

At her next follow-up appointment, the patient presents with a slight change in her condition. The nurse notes that the patient's blood pressure readings have edged slightly higher, now averaging around 145-150/90-95 mmHg. Although still within the range considered manageable, this subtle increase prompts the healthcare team to pay closer attention. The patient reports that her mild headaches have become more frequent, occurring almost daily, though they remain manageable with rest and hydration. She still denies any visual disturbances or significant new swelling, which is reassuring. Her adherence to lifestyle modifications, such as stress reduction and adequate rest, continues to be commendable.
The physical assessment reveals that the pitting edema in her feet and ankles has remained stable, without any signs of worsening. A repeat urinalysis shows a slight increase in proteinuria, now at a +1 level, indicating a mild progression in renal involvement. Despite these changes, the patient's other vital signs remain within normal limits: her heart rate is 78 beats per minute, her respiratory rate is 18 breaths per minute, and her temperature is 98.6°F. Fetal assessment continues to show a healthy fetal heart rate of 142 beats per minute, with good variability and regular movements, providing reassurance about fetal well-being.
Given these findings, the healthcare team discusses the importance of maintaining vigilant monitoring and possibly adjusting the management plan. They propose increasing the frequency of prenatal visits to ensure close supervision and consider the potential introduction of antihypertensive medication if blood pressure continues to rise. The patient is advised to maintain her current regimen of lifestyle modifications and symptom tracking, and to report any new or worsening symptoms immediately. This proactive approach aims to manage her mild preeclampsia effectively, preventing further complications and supporting a healthy pregnancy outcome.
Section 4
At her subsequent prenatal visit, the patient's condition remains largely stable, but there are a few notable changes that warrant attention. Her blood pressure has increased slightly, now averaging around 150-155/95-100 mmHg, which prompts the healthcare team to consider the introduction of low-dose antihypertensive medication to prevent further escalation. The patient continues to adhere to her lifestyle modifications, including a diet low in sodium and regular light exercise, both of which are crucial in managing her condition. She reports that her headaches, though still present, have not intensified further. Importantly, she denies any new symptoms such as visual disturbances or increased swelling, which is reassuring for the team.
A comprehensive review of her latest lab results reveals a further increase in proteinuria, now at a +2 level, indicating more pronounced renal involvement. This change, although still considered mild, underscores the need for closer monitoring of her renal function. Her blood tests show stable platelet counts and normal liver function tests, which are positive signs and suggest that the preeclampsia has not advanced to a more severe form. The fetal assessment remains reassuring, with consistent fetal heart rate patterns and active fetal movements, suggesting continued fetal well-being.
With these findings, the healthcare team decides to increase the frequency of the patient's prenatal visits to weekly, ensuring close monitoring of her blood pressure, proteinuria levels, and overall health status. They emphasize the importance of reporting any new symptoms promptly and reinforce the need for continued adherence to her management plan. This proactive approach aims to maintain control of her condition and support a positive pregnancy outcome, minimizing the risk of progression to severe preeclampsia or other complications.
Section 5
Following the decision to increase the frequency of prenatal visits to weekly, the patient arrives for her next appointment with a slight change in her status. During the initial assessment, her blood pressure is recorded at 160/100 mmHg, indicating a further increase despite adherence to prescribed lifestyle modifications and the recent initiation of low-dose antihypertensive medication. While her headaches remain consistent in frequency and intensity, she now reports experiencing mild dizziness occasionally, which is a new symptom. Her weight has remained stable, and there is no significant change in edema, which continues to be mild and confined to her ankles.
The healthcare team conducts a repeat urinalysis, which shows proteinuria has remained at +2, with no further increase. This finding, coupled with her stable platelet count and normal liver function tests, suggests that while her condition is still classified as mild preeclampsia, the introduction of antihypertensive medication may need reevaluation to achieve better blood pressure control. Fetal monitoring indicates that the baby continues to show good movement and reassuring heart rate patterns, which is comforting to both the patient and the care team.
In light of these developments, the healthcare team decides to adjust the antihypertensive regimen, opting to slightly increase the dose to help manage her rising blood pressure more effectively. They emphasize the importance of monitoring for any further symptoms such as visual changes or more severe headaches, which could indicate progression. The patient is encouraged to continue her low-sodium diet and regular exercise and to maintain her weekly appointments for close monitoring. This tailored approach aims to stabilize her condition and prevent any complications, ensuring the best possible outcomes for both the mother and the baby.
