The nurse notices while holding him upright that a 1-day-old newborn has a significantly indented anterior fontanelle. She immediately brings it to the attention of the physician. What does this finding most likely indicate?
Increased intracranial pressure.
Vernix caseosa.
Dehydration.
Cyanosis.
The Correct Answer is C
The correct answer is c. Dehydration. A significantly indented anterior fontanelle in a newborn is most commonly a sign of dehydration.
Choice A reason:
Increased intracranial pressure: This statement is incorrect because increased intracranial pressure typically causes a bulging, not indented, fontanelle. Symptoms include irritability, vomiting, and a high-pitched cry.
Choice B reason:
Vernix caseosa: This statement is incorrect because vernix caseosa is a white, cheesy substance covering the skin of newborns, unrelated to fontanelle indentation. It serves as a protective layer for the baby’s skin.
Choice C reason:
Dehydration: This statement is correct. Dehydration in newborns can cause a sunken fontanelle due to the loss of fluid. Other signs include dry mouth, sunken eyes, and fewer wet diapers.
Choice D reason:
Cyanosis: This statement is incorrect because cyanosis refers to a bluish discoloration of the skin due to lack of oxygen, not related to fontanelle shape. It indicates issues with oxygenation or circulation.

Correct Answer is A
Explanation
The correct answer is choice A, delayed respiratory depression.
Choice A reason:
Delayed respiratory depression is not one of the main nursing observations for a woman who receives epidural or intrathecal opioids. Epidural and intrathecal opioids are administered for pain relief during labor or after certain surgeries, and they act locally within the spinal cord to block pain signals. Unlike systemic opioids, which can cause respiratory depression when given in high doses, epidural and intrathecal opioids have a more limited systemic effect, reducing the risk of respiratory depression. Therefore, monitoring for delayed respiratory depression is not a primary concern in this context.
Choice B reason:
Choice B is a valid nursing observation for a woman who receives epidural or intrathecal opioids. These opioids can cause temporary paralysis or weakness in the lower extremities as a side effect of their action on the nerves in the spinal cord. Nurses need to assess the woman's ability to move her lower extremities and ensure her safety and comfort while this effect is present.
Choice C reason:
Choice C is a valid nursing observation for a woman who receives epidural or intrathecal opioids. Pruritus, which refers to itching or a sensation of itchiness, is a common side effect of opioids, including those administered via epidural or intrathecal routes. The nurse should assess the woman for any signs of pruritus and manage it appropriately if it occurs.
Choice D reason:
Choice D is a valid nursing observation for a woman who receives epidural or intrathecal opioids. Nausea and vomiting are common side effects of opioids, and they can occur after receiving these medications via epidural or intrathecal routes. The nurse should monitor the woman for any signs of nausea and vomiting and provide supportive care if needed.
Correct Answer is A
Explanation
Choice A reason:
Uteroplacental insufficiency is a condition where the placenta cannot deliver enough oxygen and nutrients to the fetus. This can cause fetal hypoxia and distress, which can be detected by late decelerations on the fetal heart rate monitor. Late decelerations are defined as a decrease in the fetal heart rate that begins after the peak of the contraction and returns to baseline after the contraction ends. This indicates that the fetus is not tolerating the reduced blood flow during the contractions and needs immediate intervention. • Choice B reason:
Umbilical cord compression is a condition where the umbilical cord is squeezed or twisted, reducing the blood flow and oxygen to the fetus. This can cause variable decelerations on the fetal heart rate monitor. Variable decelerations are defined as a decrease in the fetal heart rate that varies in timing, shape, and duration, and may or may not be associated with contractions. This indicates that the fetus is experiencing intermittent or sustained cord compression and may need repositioning or other interventions. • Choice C reason:
Maternal bradycardia is a condition where the mother's heart rate is slower than normal, usually less than 60 beats per minute. This can cause reduced blood flow and oxygen to the placenta and the fetus, but it does not cause late decelerations on the fetal heart rate monitor. Maternal bradycardia can be caused by various factors, such as medications, hypothermia, hypothyroidism, or vagal stimulation. It may need treatment depending on the cause and severity. • Choice D reason:
Fetal head compression is a condition where the fetal head is pressed against the cervix or the pelvic floor during labor, stimulating the vagus nerve and slowing down the fetal heart rate. This can cause early decelerations on the fetal heart rate monitor. Early decelerations are defined as a decrease in the fetal heart rate that begins with the onset of the contraction and returns to baseline with the end of the contraction. This indicates that the fetus is descending in the birth canal and is usually a normal and benign finding.
