Nursing Elites

1. The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?

• A. Betamethasone (Celestone).
• B. Magnesium sulfate.
• C. Terbutaline (Brethine).
• D. Ampicillin.

Correct answer: A

Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.

2. The LPN/LVN identifies crepitus when examining the chest of a newborn who was delivered vaginally. Which further assessment should the nurse perform?

• A. Elicit a positive scarf sign on the affected side.
• B. Observe for an asymmetrical Moro (startle) reflex.
• C. Watch for swelling of fingers on the affected side.
• D. Note paralysis of the affected extremity and muscles.

Correct answer: B

Rationale: Crepitus in a newborn's chest following vaginal delivery may indicate a clavicle fracture. Observing for an asymmetrical Moro reflex is essential because it can indicate potential nerve damage or fracture, which may be associated with the crepitus identified during the examination.

3. The healthcare provider is assessing a 38-week gestation newborn infant immediately following a vaginal birth. Which assessment finding best indicates that the infant is transitioning well to extrauterine life?

• A. Positive Babinski reflex.
• B. Flexion of all four extremities.
• C. Heart rate of 220 beats/min.
• D. Cries vigorously when stimulated.

Correct answer: D

Rationale: A vigorous cry upon stimulation indicates that the newborn has good respiratory effort and is transitioning well to life outside the womb. It shows that the infant's airways are clear, and they are able to establish effective breathing, a crucial aspect of transitioning successfully to extrauterine life. Choices A, B, and C are not the best indicators of successful transition to extrauterine life. The Babinski reflex and flexion of extremities are normal neonatal reflexes and do not specifically indicate successful transition. A heart rate of 220 beats/min is abnormally high for a newborn and could indicate distress rather than a smooth transition.

4. When performing the daily head-to-toe assessment of a 1-day-old newborn, the nurse observes a yellow tint to the skin on the forehead, sternum, and abdomen. Which action should the nurse take?

• A. Measure bilirubin levels using transcutaneous bilirubinometry.
• B. Evaluate cord blood Coombs test results.
• C. Review maternal medical records for blood type and Rh factor.
• D. Prepare the newborn for phototherapy.

Correct answer: A

Rationale: The presence of a yellow tint on the skin of a newborn suggests jaundice. The initial step in managing jaundice in a newborn is to measure bilirubin levels, typically done using transcutaneous bilirubinometry. This measurement helps determine the severity of jaundice and guides appropriate treatment interventions. Evaluating cord blood Coombs test results or reviewing maternal medical records for blood type and Rh factor are not the immediate actions indicated when jaundice is suspected. Phototherapy may be considered after confirming elevated bilirubin levels and assessing the need for treatment.

5. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?

• A. Place the infant in a knee-chest position.
• B. Administer morphine sulfate.
• C. Start intravenous fluids.
• D. Provide 100% oxygen by face mask.

Correct answer: A

Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions. Administering morphine sulfate (choice B) is not the first-line treatment for tetralogy of Fallot crisis. Starting intravenous fluids (choice C) may be necessary but is not the priority in this situation. Providing 100% oxygen by face mask (choice D) may not fully address the underlying issue of decreased systemic vascular resistance that leads to cyanosis in tetralogy of Fallot.
