Nursing Elites

1. What is the purpose of the pediatric assessment triangle?

• A. Detect immediate life threats through a quick hands-on assessment.
• B. Identify if the child has a medical condition or a traumatic injury.
• C. Determine if the child's problem is respiratory or circulatory in nature.
• D. Form a general impression of the child without touching them.

Correct answer: D

Rationale: The pediatric assessment triangle is used to form a rapid, hands-off general impression of the child's condition without directly touching them. This visual assessment helps in identifying children who require immediate attention and further evaluation.

2. A mother of a 6-year-old actively playing child, diagnosed with type 1 diabetes mellitus a year ago, calls a clinic nurse and reports that the child has been sick. She checked the child's urine, which was positive for ketones. What should the nurse instruct the mother to do?

• A. Administer an additional dose of regular insulin
• B. Come to the clinic immediately
• C. Encourage the child to drink liquids
• D. Hold the next dose of insulin

Correct answer: C

Rationale: Encouraging the child to drink liquids is essential in managing ketones in urine. Increased fluid intake can help prevent dehydration and aid in flushing out ketones, which is crucial in managing diabetic ketoacidosis, a serious complication of uncontrolled diabetes.

3. During the initial assessment of the newborn, which of the following data would be considered normal?

• A. Chest circumference 31.5 cm, head circumference 33.5 cm
• B. Chest circumference 30 cm, head circumference 29 cm
• C. Chest circumference 38 cm, head circumference 31.5 cm
• D. Chest circumference 32.5 cm, head circumference 36 cm

Correct answer: A

Rationale: The correct answer is A. During the initial assessment of a newborn, the average head circumference at birth is 32 to 37 cm, while the average chest circumference ranges from 30 to 35 cm. Normally, the head's circumference is about 2 cm greater than the chest circumference at birth. Choice A provides measurements of chest circumference 31.5 cm and head circumference 33.5 cm, both falling within the normal range in terms of actual size and relative size. Choices B, C, and D do not align with the typical measurements seen in a healthy newborn. Choice B has both circumferences below the average range, choice C has the chest circumference above the average, and choice D has the head circumference notably higher than the chest circumference, which is not typical for a newborn.

4. A 30-year-old woman has severe lower abdominal pain and light vaginal bleeding. She tells you that her last menstrual period was 2 months ago. On the basis of these findings, you should suspect:

• A. a normal pregnancy.
• B. a ruptured ovarian cyst.
• C. an ectopic pregnancy.
• D. a spontaneous abortion.

Correct answer: C

Rationale: Severe lower abdominal pain, light vaginal bleeding, and a history of missed periods are concerning for an ectopic pregnancy. The absence of a normal menstrual period along with these symptoms raises suspicion for an ectopic pregnancy, which requires immediate medical attention due to the risk of rupture and life-threatening complications. A normal pregnancy would typically present with different symptoms such as a positive pregnancy test and typical signs of early pregnancy. A ruptured ovarian cyst may present with similar symptoms but typically lacks the history of missed periods. A spontaneous abortion usually involves heavier bleeding and tissue passage, which is not described in this scenario.

5. 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.
