Preterm Newborn After Preeclampsia: Apgar, Glucose, and Maternal Guilt
At 35 weeks' gestation, Ms. Alvarez, age 34, is admitted with blood pressure 168/104, proteinuria, and severe headache. An emergency cesarean is performed. Her son, Mateo, weighs 2,150 g. At 1 minute his heart rate is 110, respirations are slow and irregular, he has some flexion, grimaces to suctioning, and is blue at the extremities; Apgar is 6. At 5 minutes he is pink with crying, heart rate 140, and active motion; Apgar is 8. At 12 hours his axillary temperature is 36.2°C and blood glucose is 42 mg/dL. He nurses briefly every 4 hours but falls asleep at the breast. Ms. Alvarez had one glass of wine on two occasions before she knew she was pregnant and now asks whether she caused his prematurity. She is tearful and says she feels like a failure.
1. Mateo's Apgar scores are 6 at 1 minute and 8 at 5 minutes. What do these scores indicate, and which three physiologic problems in the first 24 hours should take priority? Explain how each relates to preterm status.

The 1-minute score of 6 reflects moderate depression, not a diagnosis: heart rate 110 earns 2 points, slow/irregular respirations 1, some flexion 1, grimace 1, and acrocyanosis 1. The 5-minute score of 8 shows improvement and is reassuring, but it does not erase the need to monitor a 35-week, 2,150-g infant.
The priorities are:
- Thermoregulation. Axillary temperature 36.2°C is low. Preterm infants have little subcutaneous fat, a large surface area relative to weight, and immature vasomotor control, so they lose heat quickly and may worsen hypoglycemia and respiratory distress.
- Glucose stability. A glucose of 42 mg/dL is borderline/low for a preterm infant, especially with brief, sleep-prone feeds. Preterm infants have low glycogen stores, immature gluconeogenesis, and inconsistent intake.
- Feeding and respiratory readiness. Falling asleep at the breast suggests immature suck-swallow-breathe coordination. Monitor respiratory effort and apnea, support feeding with cues, and follow unit protocols for glucose and temperature. Apgar alone would miss these ongoing risks.
2. The nurse asks whether Ms. Alvarez's two glasses of wine before pregnancy recognition caused Mateo's prematurity. How should the clinician respond, and what developmental and counseling points matter?
Read the worked answer
The clinician should avoid both false reassurance and blame. There is no known safe amount of alcohol in pregnancy, but two isolated drinks before pregnancy recognition are not a sufficient explanation for a 35-week delivery complicated by severe preeclampsia. The most defensible inference is that preeclampsia drove the preterm birth; alcohol exposure is a separate risk to discuss without implying certain causation.
Counseling should be specific and developmental: acknowledge her tearfulness and failure statement as a possible postpartum depression signal, screen formally, and refer rather than simply reassure. Explain preterm infant cues, skin-to-skin care, feeding plans, temperature and glucose monitoring, and follow-up. Avoid a lecture that increases shame; use a collaborative stance. The key exam reasoning is that guilt is not evidence of causation, and maternal mood is itself a developmental risk for caregiving and infant outcomes.
