Which data should alert the nurse that the neonate is postmature?
Presence of lanugo
Short, chubby appearance
Presence of vernix caseosa
Cracked, peeling skin
The Correct Answer is D
Choice A: This is incorrect because lanugo is a fine, downy hair that covers the fetus in utero. It usually disappears by the 36th week of gestation, but it may persist in some preterm infants. Lanugo helps to retain body heat and protect the skin from amniotic fluid. Lanugo is not a sign of postmaturity, but of prematurity or intrauterine growth restriction.
Choice B: This is incorrect because a short, chubby appearance is typical of a term infant, who is born between 37 and 42 weeks of gestation. A term infant has a well-developed subcutaneous fat layer that gives them a rounded shape and smooth skin. A term infant also has a head circumference that is proportional to their body length and weight. A short, chubby appearance is not a sign of postmaturity, but of normal development.
Choice C: This is incorrect because vernix caseosa is a white, cheesy substance that covers the fetus in utero. It usually decreases by the 40th week of gestation, but it may remain in some term infants, especially in the skin folds. Vernix caseosa helps to moisturize and protect the skin from amniotic fluid and infection. Vernix caseosa is not a sign of postmaturity, but of term or near-term gestation.
Choice D: This is the correct answer because cracked, peeling skin is a common sign of postmaturity, which occurs when the infant is born after 42 weeks of gestation. A postmature infant has a loss of subcutaneous fat and water that results in dry, wrinkled, and desquamated skin. A postmature infant also has a large head circumference that is disproportionate to their body length and weight. Cracked, peeling skin indicates prolonged exposure to amniotic fluid and placental insufficiency.

Correct Answer is D
Explanation
Choice a) Insert an indwelling urinary catheter is incorrect because this is not a priority action for a client who has a large amount of painless, bright red vaginal bleeding. This type of bleeding is suggestive of placenta previa, which is a condition where the placenta covers part or all of the cervix, preventing normal delivery. Inserting an indwelling urinary catheter can cause trauma to the cervix or the placenta, which can worsen the bleeding and endanger the mother and the fetus. Therefore, this action should be avoided unless absolutely necessary.
Choice b) Prepare the abdominal and perineal areas is incorrect because this is not a priority action for a client who has a large amount of painless, bright red vaginal bleeding. This type of bleeding is suggestive of placenta previa, which is a condition where the placenta covers part or all of the cervix, preventing normal delivery. Preparing the abdominal and perineal areas can be done before performing a cesarean section, which is usually the preferred mode of delivery for placenta previa. However, this action should be done after stabilizing the client's condition and obtaining informed consent for surgery.
Choice c) Witness the signature for informed consent for surgery is incorrect because this is not a priority action for a client who has a large amount of painless, bright red vaginal bleeding. This type of bleeding is suggestive of placenta previa, which is a condition where the placenta covers part or all of the cervix, preventing normal delivery.
Witnessing the signature for informed consent for surgery can be done before performing a cesarean section, which is usually the preferred mode of delivery for placenta previa. However, this action should be done after stabilizing the client's condition and explaining the risks and benefits of surgery.
Choice d) Initiate IV access is correct because this is the priority action for a client who has a large amount of painless, bright red vaginal bleeding. This type of bleeding is suggestive of placenta previa, which is a condition where the placenta covers part or all of the cervix, preventing normal delivery. Initiating IV access can help to restore fluid volume, prevent hypovolemic shock, administer medications such as oxytocin or blood products if needed, and prepare for emergency cesarean section if indicated. Therefore, this action should be done as soon as possible to save the life of the mother and the fetus.
Correct Answer is D
Explanation
A. Dressing the infant in only a T-shirt and diaper is not recommended during phototherapy because it reduces the amount of skin exposed to the light, which is necessary for effective treatment. The infant should be minimally clothed to maximize light exposure.
B. Restricting parental and oral fluids is incorrect. Adequate hydration is crucial during phototherapy to prevent dehydration, as the treatment can increase fluid loss through the skin.
C. Keeping the infant supine at all times is not necessary. The infant should be repositioned frequently to ensure all areas of the skin are exposed to the phototherapy light, which helps in reducing bilirubin levels more effectively.
D. Keeping the infant's eyes covered under the light is essential to protect the eyes from potential damage caused by the intense phototherapy light. This is a standard practice to prevent retinal damage and other eye complications.
