A nurse is contributing to the care of a newborn who is experiencing hyperbilirubinemia and is receiving phototherapy.
Which of the following findings indicate that the phototherapy is effective?
Serum bilirubin level has increased from 6 hours ago.
Hemoglobin and hematocrit have increased.
Transcutaneous bilirubin (TcB) level has decreased from 6 hours ago.
Jaundice moves from chest to groin level.
The Correct Answer is C
Choice A rationale
An increase in serum bilirubin levels indicates worsening hyperbilirubinemia rather than improvement. Effective phototherapy should result in a decrease in bilirubin levels as it helps break down bilirubin into a form that can be excreted.
Choice B rationale
Hemoglobin and hematocrit levels are not directly affected by phototherapy. These values are more related to red blood cell count and do not indicate the effectiveness of phototherapy for treating hyperbilirubinemia.
Choice C rationale
A decrease in transcutaneous bilirubin (TcB) levels from 6 hours ago indicates effective phototherapy. Phototherapy reduces bilirubin levels in the blood by converting it to a water-soluble form that can be eliminated from the body.
Choice D rationale
Jaundice typically moves from the head to the lower body as bilirubin levels decrease. Movement from chest to groin level without a corresponding decrease in bilirubin levels does not necessarily indicate effective phototherapy. .

Correct Answer is A
Explanation
Choice A rationale
Heavy vaginal bleeding at 39 weeks of gestation could be due to placental abruption or placenta previa, which necessitates immediate delivery to prevent maternal and fetal complications. Preparing for cesarean birth is crucial as it allows rapid delivery, reducing the risk of maternal hemorrhage and fetal hypoxia.
Choice B rationale
Performing a cervical examination can exacerbate bleeding in cases of placenta previa or placental abruption, making it unsafe. It can disturb the placenta and lead to further complications, so this option is not recommended.
Choice C rationale
Magnesium sulfate is used to prevent seizures in preeclampsia or eclampsia, not for managing heavy vaginal bleeding. Its use is unrelated to the immediate care of a client with heavy vaginal bleeding due to suspected placental issues.
Choice D rationale
Administering antibiotics is not the immediate priority in the case of heavy vaginal bleeding at 39 weeks of gestation. The focus should be on stabilizing the mother and preparing for delivery.
Correct Answer is D
Explanation
Choice A rationale
The hearing screening test is not related to brain development but specifically to the ability to hear sounds. It assesses the infant's auditory pathway from the ear to the brainstem to identify potential hearing loss early on.
Choice B rationale
This test does not assess for heart defects. Heart defects are usually detected through physical examination, pulse oximetry screening, or echocardiography, not through auditory tests.
Choice C rationale
Seizure disorders are diagnosed based on clinical presentation and electroencephalogram (EEG) results. The hearing screening test does not have any connection to identifying seizure disorders.
Choice D rationale
The primary purpose of the newborn hearing screening is to detect if the baby can hear various sounds, enabling early intervention if hearing loss is detected. Early identification and management are essential for speech and language development.
