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. Which of the following signs would you expect to see in a child with respiratory failure?

• A. Slow, irregular breathing
• B. Flushed skin
• C. Strong cry
• D. Unconsciousness

Correct answer: A

Rationale: In a child with respiratory failure, slow, irregular breathing is a common sign. Respiratory failure impairs the ability to exchange oxygen and carbon dioxide efficiently, leading to altered breathing patterns. Flushed skin, a strong cry, or unconsciousness may not be specific signs of respiratory failure and could be indicative of other conditions. Flushed skin may be a sign of fever or increased blood flow, a strong cry may indicate pain or distress, and unconsciousness can have various causes beyond respiratory failure.

3. Why should small children ride in the backseat of a vehicle?

• A. They are much less likely to be ejected from the vehicle.
• B. The back of the front seat will provide a cushion during a crash.
• C. They can experience severe injury or death if the airbag deploys.
• D. Their legs are highly prone to injury from striking the dashboard.

Correct answer: C

Rationale: Small children should ride in the backseat of a vehicle primarily to avoid severe injury or death that may occur if the airbag deploys. In the event of a crash, the force of an airbag deployment can be dangerous for a child seated in the front seat. Placing them in the backseat reduces the risk of serious harm from airbag impact and is a safer seating position for young passengers.

4. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

5. You arrive at the scene shortly after a 3-year-old female experienced a seizure. The child, who is being held by her mother, is conscious and crying. The mother tells you that her daughter has been ill recently and has a temperature of 102.5°F. What is the MOST appropriate treatment for this child?

• A. Oxygen via non-rebreathing mask, place the child in a tub of cold water to lower her body temperature, and transport.
• B. Oxygen via the blow-by technique, transport, and request a paramedic intercept so an anticonvulsant drug can be given.
• C. Oxygen via non-rebreathing mask, avoid any measures to lower the child's body temperature, and transport at once.
• D. Oxygen via the blow-by technique, remove clothing to help reduce her fever, and transport with continuous monitoring.

Correct answer: D

Rationale: The most appropriate treatment for a child who has experienced a seizure and has a fever includes administering oxygen via the blow-by technique, removing clothing to help reduce fever, and transporting the child with continuous monitoring. Choice A is incorrect because placing the child in a tub of cold water can lead to hypothermia and is not recommended for fever reduction. Choice B is incorrect as requesting an anticonvulsant drug without proper evaluation and assessment by a healthcare provider is not appropriate. Choice C is incorrect as avoiding measures to lower the child's body temperature can worsen the situation in case of febrile seizures. Therefore, the best course of action is to provide oxygen via the blow-by technique, remove excess clothing to reduce fever, and transport the child while continuously monitoring her condition.
