A nurse is reviewing the laboratory results of a pre-term newborn who was born at 32 weeks of gestation.

Which of the following values indicates a potential complication of necrotizing enterocolitis (NEC)?

Hematocrit 45%

Platelets 150,000/mm3

White blood cell count 25,000/mm3

Blood glucose 80 mg/dL

Answer and Explanation

The Correct Answer is C

White blood cell count 25,000/mm3.

This indicates a potential complication of necrotizing enterocolitis (NEC), which is the death of intestinal tissue in premature or sick newborns. A high white blood cell count can be a sign of infection or inflammation in the bowel, which are common features of NEC.

Choice A is wrong because hematocrit 45% is within the normal range for newborns.

Hematocrit measures the percentage of red blood cells in the blood.

A low hematocrit can indicate blood loss or anemia, which can be complications of NEC, but a normal hematocrit does not rule out NEC.

Choice B is wrong because platelets 150,000/mm3 is also within the normal range for newborns.

Platelets are cells that help the blood clot. A low platelet count can indicate a consumption coagulopathy, which is a bleeding disorder that can occur in severe cases of NEC.

However, a normal platelet count does not exclude NEC.

Choice D is wrong because blood glucose 80 mg/dL is also within the normal range for newborns.

Blood glucose measures the amount of sugar in the blood.

A low blood glucose can indicate hypoglycemia, which can be caused by sepsis or other conditions that mimic NEC, but a normal blood glucose does not eliminate NEC.

Correct Answer is A

Explanation

Thromboembolism.

Prolonged bed rest increases the risk of venous stasis and blood clot formation in the lower extremities, which can lead to pulmonary embolism if the clot dislodges and travels to the lungs.

This is a life-threatening complication that requires immediate treatment.

Choice B. Placental abruption is wrong because it is not caused by bed rest, but by trauma, hypertension, cocaine use, or other factors that can cause the placenta to separate from the uterine wall.

Choice C. Uterine atony is wrong because it is not caused by bed rest, but by overdistension of the uterus, prolonged labor, infection, or other factors that can impair the contraction of the uterine muscles after delivery.

Choice D. Infection is wrong because it is not caused by bed rest, but by poor hygiene, invasive procedures, or other factors that can introduce microorganisms into the reproductive tract.

Normal ranges for maternal heart rate are 60-100 beats per minute and blood pressure are 110-140/60-90 mm Hg.

Normal range for fetal heart rate is 110-160 beats per minute.

A. Hypertension B. Hyperreflexia C. Respiratory depression D. Tachycardia

Correct Answer is C

Explanation

Magnesium sulfate is a drug that is used to prevent seizures associated with pre-eclampsia and to stop preterm labor.However, it can also cause adverse effects such as respiratory depression, which is a condition where the breathing rate becomes too slow and shallow.

Respiratory depression can be life-threatening for both the mother and the baby, so the nurse should monitor the client’s respiratory rate and oxygen saturation closely.

Choice A is wrong because magnesium sulfate can cause hypotension, not hypertension.Hypotension is low blood pressure, which can lead to dizziness, fainting, and shock.

Choice B is wrong because magnesium sulfate can cause hyporeflexia, not hyperreflexia.Hyporeflexia is a reduced or absent reflex response, which can indicate magnesium toxicity.

The nurse should check the client’s deep tendon reflexes regularly and stop the infusion if they are absent.

Choice D is wrong because magnesium sulfate can cause bradycardia, not tachycardia.

Bradycardia is a slow heart rate, which can reduce the blood flow to vital organs.
