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. A four-year-old boy is admitted to the hospital with leg pain and fever. He is pale-looking and has bruises over various areas of his body. The physician suspects acute lymphoblastic leukemia (ALL). Which test would be used to confirm the diagnosis?

• A. Bone marrow aspirate
• B. Red blood cell count
• C. Lumbar puncture
• D. Bone scan

Correct answer: A

Rationale: A bone marrow aspirate is the definitive test to confirm acute lymphoblastic leukemia (ALL) in this case. It allows for the examination of leukemic cells in the bone marrow, providing a direct assessment of the disease. Red blood cell count (Choice B) is not specific for diagnosing leukemia but may show anemia commonly seen in leukemia patients. Lumbar puncture (Choice C) is used to assess central nervous system involvement, not primarily for confirming ALL. Bone scan (Choice D) is not a standard diagnostic test for ALL and is mainly used for evaluating bone metastases in other conditions.

3. Which disease would require strict isolation of the patient?

• A. Mumps
• B. Chickenpox
• C. Exanthema subitum (roseola)
• D. Erythema infectiosum (fifth disease)

Correct answer: B

Rationale: The correct answer is B: Chickenpox. Chickenpox is highly infectious and is transmitted through direct contact, droplet spread, and contaminated objects. Due to its high communicability, strict isolation of the patient is necessary to prevent the spread of the disease. Mumps is primarily transmitted through direct contact with the infected person's saliva, with peak contagiousness before the onset of swelling. Exanthema subitum (roseola) has an unknown transmission source. Erythema infectiosum (fifth disease) is contagious before the appearance of symptoms. Therefore, these diseases do not require the same level of strict isolation as chickenpox.

4. The nurse is administering activated charcoal to a preschool child with acetaminophen (Tylenol) poisoning. What potential complications from the use of activated charcoal should the nurse plan to assess for?

• A. Diarrhea
• B. Vomiting
• C. All are correct
• D. Intestinal obstruction

Correct answer: C

Rationale: Common complications of activated charcoal administration include diarrhea and vomiting. Intestinal obstruction can occur if the charcoal forms a mass in the intestines. Fluid retention is less likely and not typically a complication associated with activated charcoal.

5. According to Erikson’s developmental theory, toddlers need to be encouraged to become independent to successfully complete which developmental challenge?

• A. Trust vs. mistrust
• B. Industry vs. inferiority
• C. Autonomy vs. shame and doubt
• D. Initiative vs. guilt

Correct answer: C

Rationale: The correct answer is C: Autonomy vs. shame and doubt. Erikson's developmental stage for toddlers focuses on the conflict between developing a sense of independence (autonomy) and feelings of inadequacy (shame and doubt). Encouraging toddlers to explore their environment and make choices helps them build self-confidence and independence. Choices A, B, and D are incorrect because trust vs. mistrust relates to infancy, industry vs. inferiority is associated with school-age children, and initiative vs. guilt is linked to preschoolers.
