38-Year-Old Female with Preeclampsia

Ms. Johansen, 38, is 26 weeks pregnant with her first child. She was diagnosed with preeclampsia (see p. 1114) three weeks ago. Antihypertensive drugs (p. 724) and daily home care monitoring were initiated. However, her blood pressure is continuing to rise and is now 162/108 mm Hg. She complains of a constant headache, exhibits edema, and her urinalysis is positive for protein.

Her doctor has her admitted and orders further blood tests to assess Ms. Johansen's platelet level and liver function. "We may have to deliver because that’s the only cure for preeclampsia." she says to you during your clinical rotation in obstetrics. “But if we do, then the baby will have problems. It’s a tough decision because we have to balance both the mother's and the baby’s health.”

5. NCLEX-STYLE Cortisol prompts the fetal lungs to begin synthesizing surfactant. Why is this important?

a. Surfactant reduces surface tension in the alveoli, allowing the alveoli to inflate.

b. Surfactant causes vasodilation, allowing blood to flow through the lungs.

c. Surfactant is necessary to protect the cells lining the respiratory tract from drying out.

d. Surfactant attracts white blood cells into the lungs to protect them against pathogens.
