Nursing Elites

1. What action should you take if a newborn's heart rate is 50 beats/min?

• A. Begin chest compressions.
• B. Reassess in 30 seconds.
• C. Administer blow-by oxygen.
• D. Start positive-pressure ventilations.

Correct answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

2. Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and takes steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?

• A. Sodium bicarbonate from renal compensation
• B. Potassium from cell death
• C. Glucose from carbohydrate metabolism
• D. Ketone bodies from fat metabolism

Correct answer: D

Rationale: Diabetic ketoacidosis (DKA) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.

3. You have arrived for your shift on the children's ward and need to assess a 2-year-old who is accompanied by his father. Identify the appropriate strategy to successfully complete a focused assessment:

• A. Allow the child to inspect the equipment for faults before and during assessment
• B. Ask parent to leave room until assessment has been completed
• C. Perform traumatic or invasive procedures first
• D. Have the child sit in parents lap and request assistance if necessary

Correct answer: D

Rationale: Having the child sit in parent's lap can help reduce anxiety and allow for a more accurate assessment.

4. What is the appropriate technique for performing two-rescuer CPR on a 4-year-old child?

• A. 15 compressions to 2 ventilations, compressing the sternum with your thumbs, and delivering at least 100 compressions per minute.
• B. 30 compressions to 2 ventilations, compressing the chest one third the depth of the chest, and delivering each breath over 1 second.
• C. 15 compressions to 2 ventilations, compressing the sternum with the heel of your hand, and ventilating until visible chest rise occurs.
• D. 30 compressions to 2 ventilations, compressing the sternum with the heel of both hands, and delivering each breath over 1 to 2 seconds.

Correct answer: C

Rationale: When performing two-rescuer CPR on a 4-year-old child, the appropriate technique involves 15 compressions to 2 ventilations. Compressions should be done by pressing the child's sternum with the heel of your hand. Ventilations should be given until visible chest rise occurs. This technique ensures effective CPR delivery for a child in need of resuscitation.

5. 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.
