Nursing Elites

1. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?

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

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.

2. An infant is born with anencephaly. Based on the knowledge of this diagnosis, what information does the nurse consider when interacting with the family?

• A. Many treatment options exist.
• B. Immediate surgery is necessary.
• C. The condition is incompatible with life.
• D. The child will have permanent disabilities.

Correct answer: C

Rationale: The correct answer is C: 'The condition is incompatible with life.' Anencephaly is the most serious neural tube defect where both hemispheres of the brain are absent. It is incompatible with life, as there are no medical or surgical treatment options available. While some infants with mature brain stem function can maintain vital functions for a short period, anencephaly is ultimately not survivable. Choice A is incorrect as there are no treatment options for anencephaly. Choice B is incorrect as immediate surgery is not necessary for this condition. Choice D is incorrect as an infant with anencephaly will not have permanent disabilities since the condition is not compatible with life.

3. Parents of a child who will need hemodialysis ask the nurse, What are the advantages of a fistula over a graft or external access device for hemodialysis? (Select all that apply.)

• A. It is ready to be used immediately.
• B. All below
• C. There is less restriction of activity with a fistula.
• D. It produces dilation and thickening of the superficial vessels.

Correct answer: A

Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.

4. The parent of a child hospitalized with acute glomerulonephritis asks the nurse why blood pressure readings are being taken so often. What knowledge should influence the nurse's reply?

• A. The antibiotic therapy contributes to labile blood pressure values.
• B. Hypotension leading to sudden shock can develop at any time.
• C. Acute hypertension is a concern that requires monitoring.
• D. Blood pressure fluctuations indicate that the condition has become chronic.

Correct answer: C

Rationale: Acute hypertension is a common complication of acute glomerulonephritis, requiring frequent monitoring to prevent complications such as encephalopathy or heart failure. Blood pressure fluctuations can occur but are not necessarily indicative of chronic disease.

5. An infant with short bowel syndrome is receiving total parenteral nutrition (TPN). The practitioner has added continuous enteral feedings through a gastrostomy tube. The nurse recognizes this as important for which reason?

• A. Wean the infant from TPN gradually
• B. Stimulate adaptation of the small intestine
• C. Provide additional nutrients that cannot be included in the TPN
• D. Offer parents encouragement that the child is close to discharge

Correct answer: B

Rationale: Continuous enteral feedings help stimulate the small intestine's adaptation in short bowel syndrome, promoting better nutrient absorption and eventually reducing reliance on TPN. This approach is crucial for long-term management and improving the child's prognosis. Choice A is incorrect because weaning off TPN typically occurs gradually over time, not the next day. Choice C is incorrect because TPN can be adjusted to provide necessary nutrients, and enteral feedings are mainly used to stimulate intestinal function. Choice D is incorrect as the addition of enteral feedings does not necessarily indicate imminent discharge; it primarily focuses on enhancing intestinal adaptation and reducing reliance on TPN.
