Nursing Elites

1. Which of the following conditions is characterized by a 'machine-like' murmur in children?

• A. Patent ductus arteriosus
• B. Ventricular septal defect
• C. Atrial septal defect
• D. Coarctation of the aorta

Correct answer: A

Rationale: The correct answer is A, Patent ductus arteriosus. This condition is characterized by a continuous 'machine-like' murmur due to abnormal blood flow between the aorta and pulmonary artery. Ventricular septal defect (choice B) is characterized by a harsh holosystolic murmur, atrial septal defect (choice C) typically presents with a fixed split S2 and a pulmonary flow murmur, and coarctation of the aorta (choice D) is associated with a systolic murmur in the back and bilateral lower extremities.

2. With the National Center for Health Statistics criteria, which body mass index (BMI)-for-age percentiles should indicate the patient is at risk for being overweight?

• A. 10th percentile
• B. 75th percentile
• C. 85th percentile
• D. 95th percentile

Correct answer: C

Rationale: A BMI-for-age at the 85th percentile indicates a child is at risk for being overweight, according to the National Center for Health Statistics criteria.

3. A six-year-old child is admitted to the hospital with a diagnosis of urinary tract infection. Which of these factors contribute to urinary tract infections in young children?

• A. Excessive intake of carbonated beverages.
• B. Insufficient water intake to flush the kidneys.
• C. Voiding pattern of 5-6 times a day.
• D. Infrequent voiding which results in urinary stasis.

Correct answer: D

Rationale: Infrequent voiding can lead to urinary stasis, which increases the risk of urinary tract infections by allowing bacteria to multiply in the bladder. Encouraging regular voiding and proper hydration can help prevent UTIs. Choices A, B, and C are incorrect. Excessive intake of carbonated beverages may irritate the bladder but is not a direct cause of UTIs. Insufficient water intake can concentrate urine but does not necessarily lead to infections. A voiding pattern of 5-6 times a day is within the normal range and is not associated with increased UTI risk.

4. The nurse is caring for a child with sickle cell anemia with the following order: Morphine Sulfate 2 mg IV every 24 hours. Morphine Sulfate is available in 10 mg/1mL. How many mL should the nurse administer?

• A. 0.2 mL
• B. 0.5 mL
• C. 1 mL
• D. 2 mL

Correct answer: A

Rationale: To administer 2 mg of Morphine Sulfate when the concentration is 10 mg/mL, the nurse should administer 0.2 mL (2 mg / 10 mg/mL = 0.2 mL). Choice B, 0.5 mL, is incorrect because it is the result of dividing 2 mg by 4 mg/mL instead of 10 mg/mL. Choice C, 1 mL, is incorrect as it would be the result of dividing 2 mg by 2 mg/mL. Choice D, 2 mL, is incorrect as it would be the result of dividing 2 mg by 1 mg/mL.

5. A 6-year-old child has patient-controlled analgesia (PCA) for pain management after orthopedic surgery. The parents are worried that their child will be in pain. What should your explanation to the parents include?

• A. The child will continue to sleep and be pain-free
• B. Parents cannot administer additional medication with the button
• C. The pump can deliver baseline and bolus dosages
• D. There is a high risk of overdose, so monitoring is done every 15 minutes

Correct answer: C

Rationale: PCA pumps are designed to deliver both a continuous baseline dose and patient-activated bolus doses, which can help manage pain effectively while minimizing the risk of overdose.
