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
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 B
Explanation
Instruct the client to empty her bladder.This is because a full bladder can interfere with the insertion of the needle and increase the risk of injury to the bladder or the uterus.Emptying the bladder also reduces discomfort during the procedure.
Choice A is wrong because administering tocolytic medication to stop contractions is not necessary before amniocentesis.Tocolytic medication can have side effects and should only be used when there is a clear indication of preterm labor.
Choice C is wrong because obtaining informed consent from the client is not a nursing action, but a medical one.The nurse can assist in providing information and answering questions, but the final consent should be obtained by the doctor who will perform the procedure.
Choice D is wrong because monitoring fetal heart rate and activity is not a specific action before amniocentesis, but a routine part of prenatal care.Fetal heart rate and activity can be affected by many factors, such as maternal position, fetal sleep cycle, or maternal blood sugar level.
Monitoring them before amniocentesis does not provide any useful information for the procedure.
Correct Answer is A
Explanation
Leukocoria (white pupils) is a symptom of retinopathy of prematurity (ROP), an eye disease that can happen in premature babies.ROP happens when abnormal blood vessels grow on the retina, the light-sensitive layer of tissue in the back of the eye.
Choice B is wrong because strabismus (crossed eyes) is not a symptom of ROP, but a possible complication that can occur later in life.
Choice C is wrong because nystagmus (involuntary eye movements) is not a symptom of ROP, but another possible complication that can occur later in life.
Choice D is wrong because it includes choices B and C, which are incorrect.
Normal ranges for gestational age and birth weight are 38 to 42 weeks and 5.5 to 10 pounds, respectively.Babies born before 31 weeks or weighing less than 3 pounds are at risk for ROP.
