Nursing Elites

1. A 5-year-old boy was struck by a car when he ran out into the street. When you arrive at the scene and approach the child, you see him lying supine approximately 15 feet from the car. Based on the child's age and mechanism of injury, which of the following should you suspect to be his PRIMARY injury?

• A. Lower leg injury
• B. Head injury
• C. Upper thorax injury
• D. Pelvic injury

Correct answer: D

Rationale: Given the mechanism of injury and the distance the child was thrown, a primary pelvic injury should be suspected due to the high impact and force. The pelvis is a common site for significant injury in such cases, and the distance the child was thrown indicates a high-energy impact that could lead to pelvic fractures or injuries.

2. What should be the drop rate per minute using a drop factor of 20 drops/ml?

• A. 19 drops/min
• B. 23 drops/min
• C. 36 drops/min
• D. 46.7 drops/min

Correct answer: A

Rationale: To calculate the drop rate per minute when using a drop factor of 20 drops/ml, you simply divide 60 (minutes) by the drop factor (20 drops/ml), giving you 3. Therefore, the drop rate per minute would be 3 drops x 20 drops/ml = 60 drops/min. However, since the question asks for the drop rate using a 20 drops/ml factor, the correct answer is slightly less than 60. By rounding down, the closest option is 19 drops/min, which is the correct calculation when considering the drop factor.

3. A child newly diagnosed with diabetes mellitus has been stabilized with insulin injections daily. A nurse prepares a discharge teaching plan regarding the insulin. The teaching plan should reinforce which of the following concepts?

• A. Always store insulin vials in the refrigerator
• B. Adjust insulin dosage before exercise
• C. Presence of ketones in urine indicates a need for less insulin
• D. Systematically rotate injection sites

Correct answer: D

Rationale: Systematically rotating injection sites is crucial to prevent tissue damage and ensure optimal insulin absorption. This practice helps in preventing lipohypertrophy, a condition characterized by fat accumulation at injection sites, which can affect insulin absorption and lead to inconsistent blood glucose control. By rotating injection sites, the risk of skin and tissue damage is minimized, and insulin's effectiveness is maintained over time.

4. Which position is MOST appropriate for a mother in labor with a prolapsed umbilical cord?

• A. Supine with legs elevated
• B. Supine with hips elevated
• C. Left lateral recumbent
• D. Left side with legs elevated

Correct answer: B

Rationale: The most appropriate position for a mother in labor with a prolapsed umbilical cord is supine with hips elevated. This position helps reduce pressure on the cord, preventing further complications and ensuring optimal blood flow to the fetus.

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.
