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. The nurse is providing education to the parent of a child with Beta-thalassemia. Which risk factors about the condition should the nurse include in the teaching?
- A. Hypertrophy of the thyroid
- B. Polycythemia vera
- C. Thrombocytopenia
- D. Chronic hypoxia and iron overload
Correct answer: D
Rationale: The correct answer is D: Chronic hypoxia and iron overload. Children with Beta-thalassemia often suffer from chronic hypoxia due to ineffective erythropoiesis and require frequent blood transfusions, leading to iron overload. These complications must be managed to prevent organ damage. Choices A, B, and C are incorrect. Hypertrophy of the thyroid, polycythemia vera, and thrombocytopenia are not direct risk factors associated with Beta-thalassemia. Therefore, they should not be included in the teaching regarding this condition.
3. What test is used to screen for carbohydrate malabsorption?
- A. Stool pH
- B. Urine ketones
- C. C urea breath test
- D. ELISA stool assay
Correct answer: A
Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.
4. What statement is an advantage of peritoneal dialysis compared with hemodialysis?
- A. Protein loss is less extensive.
- B. Dietary limitations are not necessary.
- C. It is easy to learn and safe to perform.
- D. It is needed less frequently than hemodialysis.
Correct answer: C
Rationale: Peritoneal dialysis is generally easier to learn and can be safely performed at home. Although dietary limitations still apply, this method offers greater flexibility in treatment scheduling compared to hemodialysis, which often requires multiple weekly visits to a dialysis center.
5. A child is admitted for minimal change nephrotic syndrome (MCNS). The nurse recognizes that the child’s prognosis is related to what factor?
- A. Admission blood pressure
- B. Creatinine clearance
- C. Amount of protein in urine
- D. Response to steroid therapy
Correct answer: D
Rationale: The prognosis for children with MCNS is closely related to their response to steroid therapy. A favorable response to steroids usually indicates a better prognosis, while poor response may require alternative treatments and can indicate a more complicated disease course.
