Which pediatric condition is characterized by a "string sign" on an upper GI series?
- A. Intussusception
- B. Hypertrophic pyloric stenosis
- C. Hirschsprung disease
- D. Meckel diverticulum
Correct Answer: B
Rationale: The correct answer is B: Hypertrophic pyloric stenosis. The "string sign" is associated with hypertrophic pyloric stenosis, a condition where the pyloric canal is narrowed, leading to gastric outlet obstruction. Intussusception (choice A) typically presents with colicky abdominal pain and currant jelly stools. Hirschsprung disease (choice C) is characterized by the absence of ganglion cells in the distal colon. Meckel diverticulum (choice D) is a congenital outpouching of the small intestine that can present with painless rectal bleeding.

What is the most appropriate intervention for a child with suspected acute appendicitis?
- A. Administer antibiotics
- B. Apply heat to the abdomen
- C. Encourage oral fluids
- D. Prepare for surgery
Correct Answer: D
Rationale: The correct answer is D: Prepare for surgery. Acute appendicitis is a surgical emergency that requires prompt removal of the appendix to prevent complications like rupture and peritonitis. Administering antibiotics (choice A) may be part of the treatment plan but should not delay surgical intervention. Applying heat to the abdomen (choice B) is not recommended as it can worsen the inflammation of the appendix. Encouraging oral fluids (choice C) is generally beneficial, but the priority in acute appendicitis is surgical intervention.
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.
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 is the first-line treatment for a febrile seizure in a child?
- A. Antipyretics
- B. Anticonvulsants
- C. Cooling blankets
- D. IV fluids
Correct Answer: A
Rationale: The correct answer is Antipyretics. Febrile seizures in children are usually associated with fever. The first-line treatment aims to reduce fever, which can help prevent febrile seizures. Antipyretics like acetaminophen or ibuprofen are commonly used for this purpose. Anticonvulsants, while used for treating seizures, are not typically the first-line treatment for febrile seizures as they are usually self-limited and resolve on their own. Cooling blankets can be used to lower body temperature in cases of hyperthermia but are not the primary treatment for febrile seizures. IV fluids may be administered in cases of dehydration due to fever or if the child cannot tolerate oral intake, but they are not the first-line treatment for febrile seizures.
What is the recommended position for a child after a tonsillectomy?
- A. Supine
- B. Prone
- C. Side-lying
- D. Fowler's position
Correct Answer: C
Rationale: The correct answer is C: Side-lying. The side-lying position is recommended after a tonsillectomy to facilitate drainage of secretions and reduce the risk of aspiration. This position helps prevent blood from pooling in the back of the throat, decreasing the chance of bleeding postoperatively. Supine (lying face up), while commonly used in other situations, may not be ideal immediately after a tonsillectomy due to the risk of airway obstruction from blood clots. Prone (lying face down) is not recommended as it can hinder breathing and increase the risk of complications. Fowler's position (semi-sitting) is also not typically used after a tonsillectomy because it may cause discomfort and hinder proper drainage.
