Nursing Elites

1. The nurse is preparing to administer vitamin K to a newborn. The mother asks why this injection is necessary. What is the nurse's best response?

• A. It helps the baby's liver function properly.
• B. It prevents bleeding disorders in the newborn.
• C. It boosts the baby's immune system.
• D. It promotes the baby's growth and development.

Correct answer: B

Rationale: The correct answer is B. Vitamin K is administered to newborns to prevent bleeding disorders since they have low levels of vitamin K, which is essential for blood clotting. By providing this injection, the nurse ensures that the newborn has an adequate supply of vitamin K to support proper blood clotting and prevent potential bleeding complications. Choices A, C, and D are incorrect because vitamin K's primary role in newborns is related to blood clotting and preventing bleeding, not liver function, immune system, or growth and development.

2. Before drying off the newborn after birth, which assessment finding should the healthcare professional document to ensure an accurate gestational rating on the Ballard gestational assessment tool?

• A. Amount and area of vernix coverage
• B. Creases on the sole
• C. Size of the areola
• D. Body surface temperature

Correct answer: A

Rationale: To ensure an accurate gestational rating on the Ballard gestational assessment tool, healthcare professionals should document the amount and area of vernix coverage before drying the newborn. Drying the baby after birth could disturb the vernix, potentially affecting the gestational age assessment. Assessing and documenting the vernix coverage beforehand enables a more precise evaluation using the Ballard gestational assessment tool. Choices B, C, and D are incorrect as they are not directly related to gestational rating on the Ballard assessment tool.

3. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.

4. The instructor is teaching a group of new mothers about infant care. Which statement indicates that further teaching is needed?

• A. I should put my baby to sleep on their back.
• B. I can give my baby water if they seem thirsty.
• C. Breastfeeding provides all the nutrients my baby needs.
• D. I should burp my baby after each feeding.

Correct answer: B

Rationale: The correct answer is B. Newborns do not need additional water as breast milk or formula provides all the necessary hydration. Giving water to infants can be harmful and is not recommended as it can interfere with the balance of electrolytes in their bodies. Choice A is correct as placing babies on their back for sleep is the recommended safe sleeping position. Choice C is also correct as breastfeeding does provide all the essential nutrients for babies. Choice D is correct as burping the baby after each feeding helps prevent discomfort from trapped air.

5. What percentage of total body surface area has been burned in a 5-year-old child who experienced partial-thickness burns to his head, anterior chest, and both upper extremities?

• A. 45%
• B. 63%
• C. 72%
• D. 54%

Correct answer: A

Rationale: According to the pediatric rule of nines, the head and neck represent 18%, the anterior chest and abdomen 18%, and each arm 9%. By adding these percentages (18% + 18% + 9% + 9% = 45%), we find that 45% of the total body surface area has been burned in this child.
