A nurse is assessing a client who has preeclampsia and received a dose of calcium gluconate to treat magnesium sulfate toxicity.
Which of the following findings should the nurse identify as an indication that calcium gluconate was effective?

The correct answer is Choice A

Choice A rationale: Blood urea nitrogen (BUN) level of 25 mg/dL exceeds the normal range of 10 to 20 mg/dL and may indicate impaired renal function or dehydration. In pregnancy, elevated BUN is concerning because renal perfusion is typically increased, leading to lower BUN levels. A rise suggests possible renal compromise, which can affect fetal development and maternal health. It warrants provider notification to assess for underlying pathology such as preeclampsia or renal insufficiency.

Choice B rationale: Hemoglobin level of 10.2 mg/dL is slightly below the normal pregnancy range of 11 to 16 mg/dL, indicating mild anemia. However, in the context of pregnancy, especially with a known history of anemia, this value is not critically low. Iron supplementation and dietary adjustments are typically sufficient. It does not represent an acute complication unless accompanied by symptoms like fatigue, pallor, or tachycardia. Therefore, it does not require immediate provider notification.

Choice C rationale: Fasting blood glucose of 70 mg/dL is at the lower end of the normal range for pregnancy, which spans from 70 to 110 mg/dL. This value is physiologically acceptable and does not indicate hypoglycemia or gestational diabetes. During pregnancy, insulin sensitivity fluctuates, but a fasting glucose of 70 mg/dL is not pathologic. No intervention is needed unless symptomatic hypoglycemia occurs. Thus, this result is not indicative of a prenatal complication.

Choice D rationale: Hematocrit level of 32% is slightly below the normal pregnancy range of 33 to 47%, reflecting mild dilutional anemia due to plasma volume expansion. This is a common physiological adaptation in pregnancy and not necessarily pathologic. Unless accompanied by symptoms or a significant drop in hemoglobin, this value alone does not indicate a prenatal complication. Monitoring and nutritional support are appropriate, but urgent provider notification is not required.

Choice A rationale

Starting each feeding with the most sore breast can worsen the condition, as the infant initially sucks more vigorously at the beginning of a feeding. This might increase the pain and damage to the already sore breast.

Choice B rationale

Moisture-proof lining in breast pads can cause an accumulation of moisture, creating a breeding ground for bacteria. This can exacerbate soreness and lead to infections such as mastitis.

Choice C rationale

Breastfeeding less frequently can lead to engorgement and plugged ducts, which can further complicate breast soreness and potentially decrease milk supply. Regular feeding helps in maintaining milk flow and production.

Choice D rationale

Colostrum has natural healing properties, including immunoglobulins and growth factors, that can help heal sore and cracked nipples. Applying colostrum can promote faster recovery and reduce discomfort.
