Client and Purpose
The client is a 26-year-old woman in her second pregnancy, at 30 weeks and 2 days of gestation by first-trimester ultrasound, seen for a scheduled prenatal visit at a community obstetric clinic. Her first pregnancy three years ago ended in an uncomplicated vaginal birth at 39 weeks. She has no chronic medical conditions, takes a prenatal vitamin and works as a dental receptionist. Her body mass index before pregnancy was 31. The client and the clinic are composites written for this assignment.
Pregnancy is a special population for health assessment because nearly every body system changes in ways that would be abnormal in a nonpregnant adult, while a small number of findings that look like ordinary pregnancy discomforts can be early signs of serious illness. The task in this assessment is not to find abnormal findings but to decide which abnormal-looking findings are expected and which expected-looking findings are not. This paper reviews the physiology that shapes that decision, reports the focused assessment, sorts the findings and describes the nurse's actions.
Physiology That Changes Interpretation
Several normal changes of pregnancy alter the meaning of routine findings. Plasma volume expands by roughly 40 to 50 percent by the third trimester, while red cell mass rises less, producing a physiologic fall in hemoglobin concentration (Soma-Pillay et al., 2016). Cardiac output increases, heart rate rises by about 10 to 20 beats per minute and systemic vascular resistance falls, so blood pressure usually falls a little in mid-pregnancy and climbs back toward its prepregnancy level late in the third trimester. The increased flow commonly produces a soft systolic ejection murmur, which is heard in most pregnant women and is not by itself a sign of heart disease.
Other changes follow from the growing uterus and hormonal effects. Pressure on the pelvic veins and inferior vena cava, together with lower plasma oncotic pressure, causes dependent edema of the feet and ankles in many women in the third trimester. Progesterone relaxes smooth muscle, slowing gastric emptying and relaxing the lower esophageal sphincter, which explains the frequency of heartburn. Respiratory rate changes little, but tidal volume rises and many women describe a mild shortness of breath at rest that is physiologic (Soma-Pillay et al., 2016).
Against that background, preeclampsia is the condition most likely to hide inside ordinary third-trimester complaints. The American College of Obstetricians and Gynecologists (ACOG, 2020) defines gestational hypertension as blood pressure reaching 140 over 90 or higher, by either number, on two occasions at least four hours apart after 20 weeks of gestation in a previously normotensive woman, and preeclampsia as that hypertension with proteinuria or with certain severe features, including new headache unresponsive to medication, visual disturbances, epigastric or right upper quadrant pain, and laboratory evidence of organ involvement. Several of those features overlap with symptoms pregnant women report every day.
Assessment Findings
Subjective data. The client reports good fetal movement, more than ten movements in the evening. She reports heartburn after dinner most nights, relieved by an antacid, and ankle swelling that is worse at the end of her workday and better in the morning. On direct questioning she reports a dull frontal headache on two of the past five days, which improved after acetaminophen and rest each time. She denies visual changes, right upper quadrant or epigastric pain distinct from her heartburn, and swelling of the face or hands. She denies vaginal bleeding, fluid leakage and regular contractions.
Objective data. Seated, with a large adult cuff and a five-minute rest first, her blood pressure read 136/88 mm Hg; a repeat after ten minutes was 134/86 mm Hg. Her blood pressure at 24 weeks was 112/70 mm Hg and at her first visit was 110/68 mm Hg. Pulse is 92 and regular and respirations are 18; pulse oximetry reads 99 percent without supplemental oxygen. Weight has increased by 2.3 kg in the four weeks since her last visit, compared with 1.4 kg in the four weeks before that. Auscultation finds a soft grade 2 of 6 systolic murmur, loudest along the left sternal edge and not radiating. Lungs are clear. Fundal height is 30 cm. Fetal heart rate by Doppler is 142 beats per minute. There is 1+ pitting edema of both ankles, none of the hands or face. Deep tendon reflexes are 2+ and symmetric without clonus. Urine dipstick shows negative protein and negative glucose.
Sorting the Findings
Expected at 30 weeks. The heartburn, the ankle edema that worsens through the day and resolves overnight, the pulse of 92, the soft systolic murmur and the fundal height matching gestational age are all consistent with normal third-trimester physiology. Each one, taken alone in a nonpregnant woman, might prompt further evaluation; in this client, each is explained by the changes described above and matches the pattern the physiology predicts. The murmur is soft, systolic and without radiation, and she has no symptoms of cardiac disease, so it was documented as a flow murmur consistent with pregnancy.
Requiring closer attention. Three findings, none of them alarming on their own, form a pattern that does not fit the expected curve. Her blood pressure of 136/88 mm Hg does not meet the diagnostic threshold, but it has risen from 112/70 mm Hg in six weeks at a point when pressure should be returning only gradually toward baseline. Her weight gain has nearly doubled over the last four weeks, which can reflect fluid retention. And she has had two headaches in five days, which responded to acetaminophen and therefore do not meet the definition of a severe feature, but which are new. No single finding here is abnormal, yet together they describe the early shape of a condition that is defined by thresholds it has not yet crossed.
The negative protein on dipstick, normal reflexes and absence of visual symptoms or right upper quadrant pain are important negatives, and they are why the client did not meet criteria for gestational hypertension or preeclampsia at this visit. The pattern is a reason to shorten the interval to the next assessment, not a diagnosis.
Nursing Actions and Teaching
The nurse reported the blood pressure trend, the weight change and the headaches to the certified nurse-midwife before the client left. The midwife ordered baseline preeclampsia laboratory tests, including a complete blood count, liver enzymes, creatinine and a urine protein-to-creatinine ratio, and scheduled a blood pressure check in three days instead of the routine two weeks. The client was already taking low-dose aspirin, which had been started at 14 weeks because her body mass index and the fact that her mother had preeclampsia placed her at moderate risk; federal preventive guidance calls for low-dose aspirin after 12 weeks of gestation for people at high risk of preeclampsia (U.S. Preventive Services Task Force [USPSTF], 2021), and many practices extend it to people with several moderate risk factors.
Teaching focused on the specific symptoms that would require a same-day call or a visit to labor and delivery: a headache that does not improve with acetaminophen, any change in vision, pain under the right ribs or in the upper abdomen that differs from her usual heartburn, swelling that appears quickly in her face or hands, and a baby who is moving less than usual. The nurse asked the client to repeat the list and gave it to her in writing. She was also taught to sit with her feet elevated during breaks at work, which addresses the ankle edema without masking the more important signs. Jarvis and Eckhardt (2024) emphasize that teaching warning signs in the client's own words is part of prenatal assessment, because the most important findings of the next few weeks will be the ones she notices first.

How this NUR 4033 Module 5 example is structured
NUR 4033 Module 5 often turns to special populations, where one finding carries different weight, and many sections let students choose older adults, children or pregnancy; your classroom's instructions set the population and format. This example explains the physiology that changes interpretation, reports the assessment findings, and then sorts them into two groups: findings expected at 30 weeks and findings that call for closer attention. The final section shows how the nurse acted on that sorting, including what was taught and when the client will be seen again. Sorting by weight rather than by body system is what makes the paper answer the module's question.
NUR4033 Module 5 questions, answered
Which special population should I choose for NUR4033 Module 5?
NUR4033 Module 5 often lets students choose among older adults, infants and children, and pregnant women, or it assigns one. Choose the group you can describe most accurately, and focus on findings that change meaning in that population. Your classroom's instructions decide the population, the format and whether a case study or a volunteer is expected.
How do I show that I understand a special population?
Explain the normal physiology that changes interpretation, then show at least one finding that would be abnormal in a typical adult but expected in your population, and one that looks ordinary but deserves attention. Sorting findings by their weight in that population, rather than listing them by system, demonstrates the reasoning the module is assessing.
Do I need to cite clinical guidelines in an assessment paper?
Where you state a threshold or a recommendation, yes. Blood pressure criteria for preeclampsia, screening intervals for children or fall-risk tools for older adults should all come from a named guideline or recognized source. Cite the course textbook for technique and a guideline for thresholds, and keep diagnosis within the appropriate provider's role.
