Correct Answer is C
Explanation
Choice A rationale:
Maternal hemoglobin and hematocrit levels are important indicators of the mother's health but are not direct indicators of fetal well-being.
Choice B rationale:
A Coombs test is performed on newborns to assess for hemolytic disease, not to monitor fetal well-being.
Choice C rationale:
A biophysical profile assesses multiple parameters of fetal well-being, including fetal heart rate, fetal movement, fetal breathing, amniotic fluid volume, and fetal tone.
Choice D rationale:
An alpha-fetoprotein test is a screening test for neural tube defects and chromosomal abnormalities but is not typically used to monitor fetal well-being in hypertensive pregnancies.
Correct Answer is B
Explanation
Choice A rationale:
Morphine subcutaneously can help reduce anxiety and stress, but supplying oxygen is the priority intervention.
Choice B rationale:
During a hypercyanotic spell ("tet spell"), the infant's oxygen levels drop, leading to cyanosis (blue skin) and distress. Administering oxygen can help improve oxygen saturation and alleviate the spell.
Choice C rationale:
Calming and soothing the child may not be sufficient to address the oxygen saturation issue during a hypercyanotic spell.
Choice D rationale:
Placing the infant in a knee-chest position can help improve blood flow, but administering oxygen should be the initial step.
