Nursing Elites

1. The healthcare provider is preparing to administer phytonadione to a newborn. Which statement made by the parents indicates understanding why the healthcare provider is administering this medication?

• A. Prevent hemorrhagic disorders.
• B. Help an immature liver.
• C. Improve insufficient dietary intake.
• D. Stimulate the immune system.

Correct answer: A

Rationale: The correct answer is A: 'Prevent hemorrhagic disorders.' Phytonadione (vitamin K) is administered to newborns to prevent hemorrhagic disease by promoting blood clotting. Newborns are born with low levels of vitamin K, which is essential for blood clotting, hence the administration to prevent hemorrhagic disorders. Choice B is incorrect because phytonadione is not given to help an immature liver but to supply vitamin K. Choice C is incorrect as phytonadione is not administered to improve dietary intake but to provide essential vitamin K. Choice D is incorrect as phytonadione does not stimulate the immune system but helps with blood clotting.

2. 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.

3. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

4. After each feeding, a 3-day-old newborn is spitting up large amounts of Enfamil® Newborn Formula, a nonfat cow's milk formula. The pediatric healthcare provider changes the neonate's formula to Similac® Soy Isomil® Formula, a soy protein isolate-based infant formula. What information should the LPN/LVN provide to the mother about the newly prescribed formula?

• A. The new formula is a coconut milk formula used with babies with impaired fat absorption.
• B. Enfamil® Formula is a demineralized whey formula that is needed with diarrhea.
• C. The new formula is a casein protein source that is low in phenylalanine.
• D. Similac® Soy Isomil® Formula is a soy-based formula that contains sucrose.

Correct answer: D

Rationale: The LPN/LVN should inform the mother that Similac® Soy Isomil® Formula is a soy-based formula containing sucrose. This formula is suitable for infants with cow's milk protein allergy or intolerance, which may be the reason for the newborn spitting up large amounts of the previous cow's milk formula.

5. Twenty minutes after a continuous epidural anesthetic is administered, a laboring client's blood pressure drops from 120/80 to 90/60. What action should the healthcare provider take?

• A. Notify the healthcare provider or anesthesiologist immediately.
• B. Continue to assess the blood pressure every 5 minutes.
• C. Place the woman in a lateral position.
• D. Turn off the continuous epidural.

Correct answer: C

Rationale: Placing the woman in a lateral position is the appropriate action to improve venous return and cardiac output, helping to stabilize the blood pressure. This position can alleviate pressure on the inferior vena cava, reducing the risk of hypotension associated with epidural anesthesia. Turning off the continuous epidural would not be the initial action as it may not be necessary and could lead to inadequate pain relief for the client. Notifying the healthcare provider or anesthesiologist immediately is premature and should be done after attempting non-invasive interventions. Continuing to assess the blood pressure every 5 minutes is important, but placing the woman in a lateral position should be the first intervention to address the hypotension.
