A nurse is reviewing the laboratory results of a client who is at 29 weeks of gestation and has pre-term labor.
Which of the following results indicates an infection that can trigger pre-term labor?
White blood cell count of 12,000/mm3
Hemoglobin level of 11 g/dL
Platelet count of 250,000/mm3
Blood glucose level of 90 mg/dL
The Correct Answer is A
A white blood cell count of 12,000/mm3 indicates an infection that can trigger pre-term labor. The normal range for white blood cell count in pregnancy is 5.7-15.0×10 9 /L, which is equivalent to 5,700-15,000/mm3.
A count above this range suggests an inflammatory response to an infection.
Choice B is wrong because a hemoglobin level of 11 g/dL is within the normal range for pregnancy, which is 10-14 g/dL.
Choice C is wrong because a platelet count of 250,000/mm3 is within the normal range for pregnancy, which is 150,000-400,000/mm3.
Choice D is wrong because a blood glucose level of 90 mg/dL is within the normal range for pregnancy, which is 70-110 mg/dL.

Correct Answer is A
Explanation
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that helps close the ductus arteriosus, a blood vessel connecting two arteries of the heart (aorta and pulmonary artery) in fetus.This drug is effective only among premature babies.
Choice B.Prostaglandin E1 is wrong because it is used to keep the ductus arteriosus open in some congenital heart defects that require surgery.
Choice C.Furosemide is wrong because it is a diuretic that reduces fluid retention and blood pressure, but does not affect the ductus arteriosus.
Choice D.Digoxin is wrong because it is a cardiac glycoside that strengthens the heart muscle contractions and regulates the heart rhythm, but does not affect the ductus arteriosus.
Correct Answer is C
Explanation
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.
