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 should preoperative care of a newborn with an anorectal malformation include?

• A. Frequent suctioning
• B. Gastrointestinal decompression
• C. Feedings with sterile water only
• D. Supine position with head elevated

Correct answer: C

Rationale: Preoperative care for a newborn with an anorectal malformation should include feedings with sterile water only. This approach is important to avoid complications before surgery. Gastrointestinal decompression is necessary to prevent abdominal distention and potential aspiration, making choice B incorrect. Frequent suctioning and placing the newborn in a supine position with the head elevated are not typically part of the preoperative care protocol for an anorectal malformation, thus choices A and D are incorrect.

3. What dietary modification is recommended for a child with cystic fibrosis?

• A. High carbohydrate
• B. Low protein
• C. High calorie
• D. Low fat

Correct answer: C

Rationale: A high-calorie diet is recommended for children with cystic fibrosis due to their increased energy needs and malabsorption issues. Cystic fibrosis affects the pancreas, leading to poor digestion and absorption of nutrients, particularly fats, which requires dietary adjustments to maintain adequate nutrition. High carbohydrate (Choice A) is not the primary focus; the emphasis is on overall calorie intake. Low protein (Choice B) is not recommended as protein intake is essential for growth and development. Low fat (Choice D) is not the best option as fat-soluble vitamin absorption is already compromised in cystic fibrosis, hence fat restriction is not a priority.

4. In the newborn, into what muscle is intramuscular vitamin K administered?

• A. Deltoid
• B. Dorsogluteal
• C. Rectus femoris
• D. Vastus lateralis

Correct answer: D

Rationale: In newborns, intramuscular vitamin K is traditionally administered into the vastus lateralis muscle. This site is preferred due to its large muscle mass and accessibility. The dorsogluteal site is not recommended for newborns due to the risk of injury to the sciatic nerve. The deltoid site is also not recommended for newborns. The rectus femoris muscle is not commonly used for intramuscular injections in newborns.

5. What is characteristic of a neonate’s vision?

• A. Pupils react to light
• B. Tear glands function
• C. Blink reflex is absent
• D. Ciliary muscles are mature

Correct answer: A

Rationale: The correct answer is A: 'Pupils react to light.' Newborns' pupils do react to light, indicating that the visual pathway is functioning. However, a neonate's vision is still developing, and they can only focus on objects close to their face. Choice B is incorrect because tear glands are functional at birth. Choice C is incorrect because the blink reflex is present in neonates and helps protect their eyes. Choice D is incorrect as neonates' ciliary muscles are not fully developed.
