A pregnant client late in the second trimester comes to the emergency department with a report of painless, bright red vaginal bleeding.
The client states, "It started all of a sudden and now it seems to have stopped.”. What action is the priority for this client on admission?

Choice A rationale

Monitoring blood glucose every six hours is insufficient for a high-risk neonate. Due to the sudden cessation of high maternal glucose supply and persistently high fetal insulin levels, the infant is at risk for rapid drops in glucose, requiring monitoring as frequently as every 1 to 3 hours initially.

Choice B rationale

High maternal glucose levels lead to fetal hyperglycemia and subsequent pancreatic beta-cell hyperplasia and hyperinsulinemia in the infant. After birth, the maternal glucose supply is cut off, but the hyperinsulinemia persists, rapidly driving the infant's blood glucose down, making hypoglycemia the most immediate, life-threatening risk.

Choice C rationale

While parent education is an important long-term goal, it is not the priority over immediate physiological assessment and intervention for a potentially life-threatening condition like hypoglycemia. Explanations should follow stabilization of the infant's vital parameters.

Choice D rationale

Estimating caloric needs is part of the overall care plan, but the priority is to identify and prevent the acute metabolic complication of hypoglycemia. Glucose monitoring and appropriate feeding or intravenous dextrose are the immediate interventions for prevention and treatment.

Choice A rationale

While the amount of blood loss is critical for determining the severity of the hemorrhage and the need for immediate treatment, it is not the priority assessment before administering methylergonovine. The amount of blood loss determines the need for the drug, but the blood pressure determines its safety before administration. Methylergonovine is a potent vasoconstrictor and must be used cautiously in clients with elevated blood pressure to prevent hypertensive crisis or stroke.

Choice B rationale

Methylergonovine is an ergot alkaloid that acts as a potent vasoconstrictor and uterine stimulant. Its primary side effect and contraindication are hypertension and preeclampsia. Because the drug dramatically increases systemic vascular resistance, it can cause a sudden, severe elevation in blood pressure. Therefore, checking the blood pressure is the priority assessment to ensure the client's pressure is within safe limits before administration, preventing potential complications like stroke.

Choice C rationale

Although a change in the level of consciousness (LOC) could indicate hypovolemic shock from severe blood loss or a hypertensive emergency, it is a secondary finding. The primary, direct, and modifiable risk associated with methylergonovine administration is its potential to cause acute, severe hypertension. Checking the client's baseline blood pressure (Choice B) is the specific, essential safety check before administering this vasoconstrictive medication.

Choice D rationale

The uterine tone or atony is the indication for the medication; the client is already diagnosed with uterine atony (flaccid uterus) causing the hemorrhage. The medication's purpose is to contract the uterus (increase tone). The priority before administration, however, is to assess the client for contraindications or serious adverse reaction risks. The potent vasoconstrictive effect on peripheral arteries makes blood pressure (Choice B) the most critical pre-administration safety assessment.
