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. What amount of fluid loss occurs with moderate dehydration?

• A. <50 ml/kg
• B. 50 to 90 ml/kg
• C. <5% total body weight
• D. >15% total body weight

Correct answer: B

Rationale: Moderate dehydration is typically defined as a loss of 50 to 90 mL/kg of body weight. This amount reflects significant fluid loss that requires medical attention but is not yet severe.

3. Which drug is usually the best choice for patient-controlled analgesia (PCA) for a child in the immediate postoperative period?

• A. Codeine sulfate (Codeine)
• B. Morphine (Roxanol)
• C. Methadone (Dolophine)
• D. Meperidine (Demerol)

Correct answer: B

Rationale: Morphine is the drug of choice for PCA in children because of its efficacy, safety profile, and rapid onset of action for pain management.

4. Which condition is characterized by a harsh, barking cough in children?

• A. Asthma
• B. Bronchiolitis

Asthma (Choice A) often presents with wheezing and shortness of breath, not a barking cough. Bronchiolitis (Choice B) typically causes wheezing and respiratory distress in infants. Pneumonia (Choice D) manifests with symptoms such as fever, productive cough, and chest pain, but not usually a barking cough.
