What is the most common cause of bronchiolitis in infants?
- A. Adenovirus
- B. Influenza virus
- C. Respiratory syncytial virus
- D. Parainfluenza virus
Correct Answer: C
Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.

When caring for a child with probable appendicitis, the nurse should be alert to recognize which sign or symptom as a manifestation of perforation?
- A. Anorexia
- B. Bradycardia
- C. Sudden relief from pain
- D. Decreased abdominal distention
Correct Answer: C
Rationale: When caring for a child with probable appendicitis, sudden relief from pain is a critical sign that could indicate perforation of the appendix. Perforation results in the release of pressure and inflammation, leading to a temporary relief of pain. Anorexia (loss of appetite) and decreased abdominal distention are symptoms commonly associated with appendicitis itself, not perforation. Bradycardia (slow heart rate) is not typically a direct manifestation of appendicitis or its complications.
Which electrolyte imbalance is a common concern in children with severe diarrhea?
- A. Hypernatremia
- B. Hypokalemia
- C. Hypercalcemia
- D. Hypomagnesemia
Correct Answer: B
Rationale: Hypokalemia is the correct answer because it is a common concern in children with severe diarrhea. Diarrhea can lead to significant potassium loss, resulting in hypokalemia. Hypernatremia (Choice A) is less common in diarrhea as sodium concentration is usually diluted by the fluid loss. Hypercalcemia (Choice C) is not typically associated with severe diarrhea. Hypomagnesemia (Choice D) can occur but is not as common as hypokalemia in this scenario.
What term describes the invagination of one segment of bowel within another?
- A. Atresia
- B. Stenosis
- C. Herniation
- D. Intussusception
Correct Answer: D
Rationale: Intussusception is the correct answer. It refers to the condition where one segment of the bowel folds into another, leading to an obstruction. Atresia (Choice A) is the absence or abnormal closure of a normal opening or tubular structure. Stenosis (Choice B) is the narrowing of a passage in the body. Herniation (Choice C) is the abnormal protrusion of an organ or tissue through a defect in its surrounding walls. Intussusception is a medical emergency commonly observed in infants and young children and necessitates prompt intervention to prevent severe complications.
What is often the initial sign of acute rheumatic fever in children?
- A. Polyarthritis
- B. Carditis
- C. Erythema marginatum
- D. Sydenham chorea
Correct Answer: A
Rationale: Polyarthritis is indeed frequently the initial sign of acute rheumatic fever in children. It presents as joint pain, swelling, and redness. Carditis (inflammation of the heart), Erythema marginatum (a skin rash), and Sydenham chorea (involuntary muscle movements) are typically seen in the later stages of acute rheumatic fever and not as the initial sign.
What is the primary concern in a child with nephrotic syndrome?
- A. Hypotension
- B. Hyperkalemia
- C. Hyperlipidemia
- D. Hypocalcemia
Correct Answer: C
Rationale: The correct answer is C: Hyperlipidemia. Children with nephrotic syndrome often present with hyperlipidemia due to altered lipid metabolism, making it a primary concern in these patients. Hypotension (choice A) is not a primary concern in nephrotic syndrome. Hyperkalemia (choice B) and hypocalcemia (choice D) are not typically associated with nephrotic syndrome and are less likely to be primary concerns in these patients.
