Nursing Elites

1. What laboratory finding should the nurse expect in a child with an excess of water?

• A. Decreased hematocrit
• B. High serum osmolality
• C. High urine specific gravity
• D. Increased blood urea nitrogen (BUN)

Correct answer: A

Rationale: Water excess typically leads to hemodilution, resulting in a decreased hematocrit. High serum osmolality and specific gravity would indicate dehydration, while elevated BUN could suggest renal impairment or dehydration, not fluid overload.

2. The school nurse suspects a testicular torsion in a young adolescent student. What action should the nurse take?

• A. Place a warm moist pack on the scrotal area.
• B. Instruct the adolescent to lie down and elevate the legs.
• C. Refer the adolescent for immediate medical evaluation.
• D. Suggest that the adolescent wear a scrotum-protecting guard.

Correct answer: C

Rationale: Testicular torsion is a surgical emergency requiring immediate medical evaluation. Applying heat or elevating the legs will not alleviate the torsion, and delaying care can lead to testicular necrosis.

3. Which condition is often associated with a "ground-glass" appearance on a chest x-ray in neonates?

• A. Pneumonia
• B. Respiratory distress syndrome
• C. Bronchopulmonary dysplasia
• D. Congenital diaphragmatic hernia

Correct answer: B

Rationale: The correct answer is B, Respiratory distress syndrome. Respiratory distress syndrome often presents with a "ground-glass" appearance on a chest x-ray in neonates due to surfactant deficiency. Choice A, Pneumonia, typically appears as patchy infiltrates on chest x-ray. Choice C, Bronchopulmonary dysplasia, is characterized by hyperinflation and fibrosis, not a ground-glass appearance. Choice D, Congenital diaphragmatic hernia, usually shows mediastinal shift and bowel loops in the chest cavity on x-ray, not a ground-glass appearance.

4. Urinary tract anomalies are frequently associated with what irregularities in fetal development?

• A. Myelomeningocele
• B. Cardiovascular anomalies
• C. Malformed or low-set ears
• D. Defects in lower extremities

Correct answer: C

Rationale: Malformed or low-set ears are often associated with congenital urinary tract anomalies, as both the ears and kidneys develop around the same time during fetal growth. Myelomeningocele, cardiovascular anomalies, and lower extremity defects are less commonly associated with UT anomalies.

5. What diagnostic test allows visualization of renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes?

• A. Renal ultrasonography
• B. Computed tomography
• C. Intravenous pyelography
• D. Voiding cystourethrography

Correct answer: A

Rationale: Renal ultrasonography provides imaging of the renal parenchyma and pelvis without the risks associated with radiation or radioactive isotopes, making it a safer option, especially for children.
