A nurse is reviewing the laboratory results of a newborn who is 24 hr old. Which of the following findings should the nurse report to the provider?
Hemoglobin 12 g/dL.
Glucose 50 mg/dL.
Bilirubin 4 mg/dL.
Platelets 200,000/mm³.
The Correct Answer is A
The correct answer is: A. Hemoglobin 12 g/dL.
Choice A reason:
Hemoglobin levels in newborns are expected to be significantly higher than in adults due to the physiological adaptation to life outside the womb. The normal range for a newborn’s hemoglobin is approximately 14 to 24 g/dL1234. A level of 12 g/dL is below the expected range and could indicate anemia or other underlying conditions that may require further investigation and intervention by the healthcare provider.
Choice B reason:
The glucose level in a newborn can vary, especially within the first few hours after birth. Normal blood glucose levels for a newborn 1 to 2 hours old can be as low as 25 mg/dL and can rise to adult levels (60-100 mg/dL) within the first few days5. A glucose level of 50 mg/dL in a 24-hour-old newborn falls within the acceptable range and would not typically require reporting to the provider unless accompanied by symptoms of hypoglycemia.
Choice C reason:
Bilirubin levels in newborns can be elevated due to the normal breakdown of fetal hemoglobin as the baby’s liver matures. Normal bilirubin levels for a newborn can range from 1.0 to 12.0 mg/dL6. A bilirubin level of 4 mg/dL is within the normal range for a 24-hour-old newborn and is not typically a cause for concern unless there are signs of jaundice or other symptoms.
Choice D reason:
The normal platelet count for a newborn ranges from 150,000 to 450,000/mm³7. A platelet count of 200,000/mm³ is well within the normal range for a newborn and would not need to be reported to the healthcare provider.

Correct Answer is ["B","D"]
Explanation
Choice A rationale:
This would be incorrect advice. Increasing dietary fiber is commonly recommended during pregnancy to prevent constipation, but it does not address stress incontinence.
Choice B rationale:
This is a correct choice. Kegel exercises are beneficial during pregnancy to strengthen the pelvic floor muscles, which can help manage stress incontinence.
Choice C rationale:
This would be incorrect advice. Restricting daily fluid intake during pregnancy is generally not recommended as it can lead to dehydration and is unlikely to improve stress incontinence.
Choice D rationale:
This is another correct choice. Caffeine is a bladder irritant and can worsen stress incontinence, so reducing caffeine intake can be helpful.
Choice E rationale:
This would be incorrect advice. Regular exercise during pregnancy is generally encouraged unless there are specific medical reasons to avoid it. Avoiding daily exercise is not the appropriate approach to manage stress incontinence.
Correct Answer is D
Explanation
Choice A rationale:
Administering oxytocin to the client via intravenous infusion is not appropriate when the nurse notes an umbilical cord protruding through the cervix. The priority is to relieve pressure on the cord to prevent fetal compromise, and administering oxytocin could worsen the situation.
Choice B rationale:
Applying oxygen at 2 L/min via nasal cannula is not the priority when an umbilical cord prolapse is detected. The focus should be on relieving pressure on the cord and changing the client's position to alleviate the compression.
Choice C rationale:
Preparing for insertion of an intrauterine pressure catheter is not appropriate when there is an umbilical cord prolapse. The immediate concern is the potential compromise of fetal blood flow, and addressing the cord prolapse takes precedence over any other interventions.
Choice D rationale:
Assisting the client into the knee-chest position is the correct action when an umbilical cord prolapse is observed during a vaginal exam. This position helps to alleviate pressure on the cord by moving the presenting part of the fetus off the cord and can prevent further fetal distress until more definitive interventions can be performed.
