Nursing Elites

1. The nurse is caring for a child with acute renal failure. What laboratory findings should the nurse expect to find? (Select all that apply.)

• A. Hyponatremia
• B. Hyperkalemia
• C. All are applicable
• D. Elevated blood urea nitrogen level

Correct answer: C

Rationale: In acute renal failure, laboratory findings typically include hyperkalemia, hyponatremia, and elevated blood urea nitrogen (BUN) levels due to the kidneys' inability to excrete waste and balance electrolytes. Metabolic alkalosis is less common, with metabolic acidosis being more typical.

2. When assessing an infant with intussusception, what type of stool would the nurse expect to find?

• A. Soft, seedy stool
• B. Currant-jelly stool
• C. Ribbon-like stool
• D. Soft and pasty stool

Correct answer: B

Rationale: The correct answer is B: Currant-jelly stool. This type of stool, which is red and mucous-like, is a classic sign of intussusception in infants. Choice A (Soft, seedy stool) is incorrect as it does not specifically describe the characteristic stool associated with intussusception. Choice C (Ribbon-like stool) is incorrect; ribbon-like stool may be seen in conditions like colon cancer, not intussusception. Choice D (Soft and pasty stool) is also incorrect as it does not match the typical stool finding in intussusception.

3. A child with acetaminophen (Tylenol) poisoning has been admitted to the emergency department. What antidote does the nurse anticipate being prescribed?

• A. Carnitine (Carnitor)
• B. Fomepizole (Antizol)
• C. Deferoxamine (Desferal)
• D. N-acetylcysteine (Mucomyst)

Correct answer: D

Rationale: N-acetylcysteine is the specific antidote for acetaminophen poisoning, working by replenishing glutathione and preventing liver damage. The other options are antidotes for different types of poisoning (e.g., Fomepizole for methanol or ethylene glycol poisoning).

4. The nurse is performing an assessment on a 10-week-old infant. The nurse understands that the developmental characteristic of hearing at this age is which?

• A. The infant responds to his own name.
• B. The infant localizes sounds by turning his head directly to the sound.
• C. The infant turns his head to the side when sound is made at the level of the ear.
• D. The infant locates sound by turning his head to the side and then looking up or down.

Correct answer: C

Rationale: By 10 weeks, infants typically turn their heads to the side to locate the source of a sound made at ear level.

5. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Transposition of the great arteries
• C. Coarctation of the aorta
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.
