Nursing Elites

1. The nurse is using the New Ballard Score to assess the gestational age of a newborn delivered 4 hours ago. The infant's gestational age is 33 weeks based on early ultrasound and last menstrual period. The nurse expects the infant to exhibit which of the following?

• A. Full sole creases, nails extending beyond the fingertips, scarf sign showing the elbow beyond the midline
• B. Testes located in the upper scrotum, rugae covering the scrotum, vernix covering the entire body
• C. Ear cartilage folded over, lanugo present over much of the body, slow recoil time
• D. 1 cm breast bud, peeling skin and veins not visible, rapid recoil of legs and arms to extension

Correct answer: C

Rationale: The correct answer is C. Ear cartilage folded over, lanugo present over much of the body, and slow recoil time are all characteristics of a preterm infant. A is incorrect because full sole creases, nails extending beyond the fingertips, and scarf sign showing the elbow beyond the midline are features of a term infant. B is incorrect as testes located in the upper scrotum, rugae covering the scrotum, and vernix covering the entire body are also indicative of a term infant. D is incorrect because a 1 cm breast bud, peeling skin and veins not visible, and rapid recoil of legs and arms to extension are characteristics seen in a more mature infant, not a preterm newborn.

2. You are dispatched to a residence for a child with respiratory distress. The child is wheezing and has nasal flaring and retractions. His oxygen saturation is 92%. You should:

• A. place the child in a supine position.
• B. administer high-flow oxygen.
• C. begin chest compressions.
• D. administer low-flow oxygen.

Correct answer: B

Rationale: In a scenario where a child presents with respiratory distress, wheezing, nasal flaring, retractions, and an oxygen saturation of 92%, the appropriate intervention is to administer high-flow oxygen. This helps to improve oxygenation and alleviate the respiratory distress the child is experiencing. Placing the child in a supine position can worsen their condition by affecting their ability to breathe effectively. Chest compressions are not indicated in this case as the child is not in cardiac arrest. Administering low-flow oxygen may not provide adequate oxygenation for a child in respiratory distress with a saturation of 92%. Therefore, the priority is to administer high-flow oxygen to improve oxygen levels and support the child's breathing.

3. When educating the parents of a child diagnosed with hypothyroidism, the nurse mentions that the child should avoid goitrogens. Which of the following will the nurse mention as an example?

• A. Orange
• B. Tomatoes
• C. Cabbage
• D. Grapes

Correct answer: C

Rationale: Cabbage is an example of a goitrogen. Goitrogens are substances that interfere with the normal function of the thyroid gland by inhibiting iodine uptake. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contain compounds that can have this effect and should be consumed in moderation by individuals with hypothyroidism to prevent worsening of their condition.

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. 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.
