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.

The parents of a newborn with an umbilical hernia ask about treatment options. The nurse's response should be based on which knowledge?
- A. Surgery is recommended as soon as possible.
- B. The defect usually resolves spontaneously by 3 to 5 years of age.
- C. Aggressive treatment is necessary to reduce its high mortality.
- D. Taping the abdomen to flatten the protrusion is not recommended.
Correct Answer: B
Rationale: The correct answer is B. Most umbilical hernias in newborns resolve on their own by 3 to 5 years of age without the need for surgical intervention, unless complications arise. Surgery is not typically recommended for umbilical hernias in newborns due to the high rate of spontaneous resolution. Aggressive treatment is not necessary as umbilical hernias are typically benign and not associated with high mortality. Taping the abdomen is not recommended as it can cause skin irritation and does not speed up the resolution of the hernia.
The child is admitted with acute abdominal pain and possible appendicitis. What intervention is appropriate to relieve the abdominal discomfort during the evaluation?
- A. Place the child in the Trendelenburg position.
- B. Apply moist heat to the abdomen.
- C. Allow the child to assume a position of comfort.
- D. Administer a saline enema to cleanse the bowel.
Correct Answer: C
Rationale: Allowing the child to assume a position of comfort is appropriate as it helps alleviate discomfort without the risk of complications. Placing the child in the Trendelenburg position could increase intra-abdominal pressure and worsen the condition. Applying moist heat may lead to vasodilation and potential perforation in case of appendicitis. Administering a saline enema can be harmful if the appendix is inflamed or perforated.
What signs or symptoms are most commonly associated with the prodromal phase of acute viral hepatitis?
- A. Bruising and lethargy
- B. Anorexia and malaise
- C. Fatigability and jaundice
- D. Dark urine and pale stools
Correct Answer: B
Rationale: The correct answer is B: Anorexia and malaise. The prodromal phase of acute viral hepatitis is characterized by nonspecific symptoms such as anorexia (loss of appetite) and malaise (general feeling of discomfort). These symptoms typically precede the more specific signs of jaundice, dark urine, and pale stools that manifest in the icteric phase. Choices A, C, and D are incorrect because bruising and lethargy, fatigability and jaundice, and dark urine and pale stools are typically seen in later stages of acute viral hepatitis, not in the prodromal phase.
What is the recommended position for a child with epiglottitis to ease breathing?
- A. Supine
- B. Prone
- C. Tripod
- D. Semi-Fowler's
Correct Answer: C
Rationale: The correct answer is C, 'Tripod.' In children with epiglottitis, the tripod position is recommended to help open the airway and ease breathing. This position involves the child sitting upright, leaning forward, and supporting themselves with their hands on their knees or another surface. This posture helps improve air entry into the lungs by maximizing the space for breathing. Choices A (Supine), B (Prone), and D (Semi-Fowler's) are incorrect. Placing a child with epiglottitis in the supine position may further obstruct the airway, while the prone position and semi-Fowler's position do not facilitate optimal air exchange in these cases.
What component should be included in the nutritional management of a child with Crohn's disease?
- A. High fiber
- B. Increased protein
- C. Reduced calories
- D. Herbal supplements
Correct Answer: B
Rationale: The correct answer is B: Increased protein. Children with Crohn's disease require a diet high in protein to support growth and tissue repair. High fiber should be avoided as it can exacerbate symptoms of Crohn's disease. Reducing calories can lead to malnutrition, which is detrimental in this condition. Herbal supplements should be used cautiously and only under medical advice as they may interact with medications or worsen symptoms.
