A client’s maternal serum alpha-fetoprotein level is elevated at 17 weeks.
What condition should the nurse identify as the likely cause of this increase?
Multiple gestation.
Fetal hypoxia.
Down syndrome.
Neural tube defect.
The Correct Answer is D
Choice A rationale
While multiple gestation can cause an increase in maternal serum alpha-fetoprotein (MS-AFP) levels, it is not the most likely cause of an elevated MS-AFP level at 17 weeks.
Choice B rationale
Fetal hypoxia, or lack of oxygen to the fetus, is not typically associated with an increase in MSAFP levels.
Choice C rationale
Down syndrome is typically associated with lower, not higher, levels of MS-AFP891011.
Choice D rationale
An elevated level of MS-AFP at 17 weeks is most commonly associated with a neural tube defect. Neural tube defects are birth defects of the brain, spine, or spinal cord that occur during the first month of pregnancy.

Correct Answer is C
Explanation
Choice A rationale
A heart rate of 58 beats/minute is within the normal range for adults, including those who have recently given birth. Therefore, there is no need to report this to the healthcare provider.
Choice B rationale
While assessing for excessive lochia is important in postpartum care, there is no indication from the given vital signs that this is necessary.
Choice C rationale
The vital signs provided are all within normal ranges for a postpartum patient. Therefore, the appropriate action would be to document these findings in the patient’s record.
Choice D rationale
There is no indication from the given vital signs that the patient has a fever or pain, so administering a PRN dose of acetaminophen is not necessary.
Correct Answer is B
Explanation
Choice A rationale
If the child is sleeping now and is difficult to wake, this could be a sign of worsening respiratory status. Children with respiratory distress often have difficulty sleeping due to discomfort and difficulty breathing. If the child is now sleeping and difficult to wake, this could indicate a decrease in oxygen levels, leading to lethargy and decreased responsiveness. This would require immediate attention.
Choice B rationale
The vital signs provided indicate a potentially serious situation. A heart rate of 130 beats/minute is high for a 3-year-old child, indicating that the heart is working harder to pump blood. A respiratory rate of 15 breaths/minute is on the lower end of normal for a 3-year-old, which could indicate that the child is not getting enough oxygen. An oxygen saturation of 66% on a 5L face mask is dangerously low, indicating severe hypoxia. A temperature of 102.8° F(39.3° C) axillary indicates a fever, which could be a sign of infection. A blood pressure of 92/48 mm Hg is within normal range for a 3-year-old.
Choice C rationale
If the child is active and playing with toys, this could indicate that his respiratory status is not worsening. Children who are experiencing respiratory distress often have difficulty engaging in normal activities due to discomfort and shortness of breath. If the child is able to play normally, this could indicate that he is getting enough oxygen and his condition is stable.
Choice D rationale
If the child’s breathing has returned to normal, this could indicate that his respiratory status is improving. However, it’s important to continue monitoring the child closely, as respiratory conditions can change rapidly, especially in young children.
