1. What is the most frequent cause of hypovolemic shock in children?

• A. Sepsis
• B. Blood loss
• C. Anaphylaxis
• D. Heart failure

Correct answer: B

Rationale: Hypovolemic shock in children is most frequently caused by blood loss, which can result from trauma, surgery, or gastrointestinal bleeding. Sepsis and anaphylaxis can lead to different types of shock (septic and anaphylactic), and heart failure is related to cardiogenic shock.

2. What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?

• A. Infarction of renal vessels
• B. Immune complex formation and glomerular deposition
• C. Bacterial endotoxin deposition on and destruction of glomeruli
• D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation

Correct answer: B

Rationale: Postinfectious glomerulonephritis is typically caused by immune complex deposition in the glomeruli following a streptococcal infection. This immune response leads to inflammation and impaired kidney function.

3. Ongoing fluid losses can overwhelm the child’s ability to compensate, resulting in shock. What early clinical sign precedes shock?

• A. Tachycardia
• B. Slow respirations
• C. Warm, flushed skin
• D. Decreased blood pressure

Correct answer: A

Rationale: Tachycardia is an early sign of shock as the body tries to maintain cardiac output in the face of declining circulatory volume. Blood pressure often remains normal until late in the progression, at which point decompensated shock is occurring.

4. A child is admitted in acute renal failure (ARF). Therapeutic management to rapidly provoke a flow of urine includes the administration of what medication?

• A. Propranolol (Inderal)
• B. Calcium gluconate
• C. Mannitol (Osmitrol) or furosemide (Lasix)
• D. Sodium, chloride, and potassium

Correct answer: C

Rationale: Mannitol and furosemide are diuretics commonly used to induce diuresis in acute renal failure, helping to provoke urine flow and manage fluid overload. Calcium gluconate and electrolyte supplementation are used for other specific conditions and not primarily for diuresis.

5. An infant is diagnosed with a tracheoesophageal fistula. Which assessment finding should the nurse expect?

• A. Jaundice
• B. Hyperactive bowel sounds
• C. Absence of sucking, vomiting
• D. Coughing, with excessive secretion

Correct answer: D

Rationale: Coughing with excessive secretion is a common sign of tracheoesophageal fistula. In this condition, the connection between the trachea and esophagus allows saliva and food to enter the airways, leading to coughing and excessive secretions. Choice A, jaundice, is not typically associated with tracheoesophageal fistula. Hyperactive bowel sounds (Choice B) are more likely seen in conditions like gastroenteritis. Absence of sucking and vomiting (Choice C) is not a typical finding related to tracheoesophageal fistula.
