1. What factor predisposes the urinary tract to infection in children?

• A. increased fluid intake
• B. short urethra in young girls
• C. prostatic secretions in males
• D. frequent emptying of the bladder

Correct answer: B

Rationale: The short urethra in young girls predisposes them to urinary tract infections. In young girls, the proximity of the urethra to the anus and the shorter urethra compared to boys make it easier for bacteria to travel up the urinary tract, increasing the risk of infection. Increased fluid intake and frequent emptying of the bladder are actually helpful in preventing urinary tract infections by flushing out bacteria. Prostatic secretions in males are not a factor in predisposing the urinary tract to infection in children.

2. A healthcare provider is assessing a 3-month-old infant with suspected pyloric stenosis. What clinical manifestation is the healthcare provider likely to observe?

• A. Projectile vomiting
• B. Diarrhea
• C. Constipation
• D. Abdominal distension

Correct answer: A

Rationale: Projectile vomiting is a classic clinical manifestation of pyloric stenosis in infants. This occurs due to the narrowing of the pyloric sphincter, leading to the forceful expulsion of gastric contents in a projectile manner. Diarrhea (choice B) is not typically associated with pyloric stenosis. Constipation (choice C) is also not a common symptom of this condition. Abdominal distension (choice D) may occur in pyloric stenosis but is not as specific or characteristic as projectile vomiting in diagnosing this condition.

3. The nurse is reviewing the laboratory test results of a child diagnosed with disseminated intravascular coagulation (DIC). What would the nurse interpret as indicative of this disorder?

• A. Shortened prothrombin time
• B. Increased fibrinogen level
• C. Positive fibrin split products
• D. Increased platelets

Correct answer: C

Rationale: Positive fibrin split products are indicative of disseminated intravascular coagulation (DIC). In DIC, there is widespread clotting and subsequent consumption of clotting factors, leading to the formation of fibrin split products. A shortened prothrombin time (Choice A) is not typically seen in DIC as it indicates faster clotting, which is opposite to the pathophysiology of DIC. An increased fibrinogen level (Choice B) may be observed in the early stages of DIC due to the compensatory increase in production, but it is not a definitive indicator. Increased platelets (Choice D) may be seen in the early stages of DIC due to the body's attempt to compensate for clot formation, but it is not a specific finding for DIC.

4. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

5. A healthcare professional is reviewing the clinical records of infants and children with cardiac disorders who developed heart failure. What did the healthcare professional determine is the last sign of heart failure?

• A. Tachypnea
• B. Tachycardia
• C. Peripheral edema
• D. Periorbital edema

Correct answer: C

Rationale: Peripheral edema is often the last sign of heart failure in infants and children as it indicates significant fluid retention and circulatory compromise. Tachypnea (Choice A) and tachycardia (Choice B) are early signs of heart failure due to the body's compensatory mechanisms. Periorbital edema (Choice D) can occur in heart failure but is not typically the last sign; it is more commonly associated with renal or hepatic dysfunction.
