1. What is the typical presentation of pyloric stenosis in infants?

• A. Bilious vomiting
• B. Projectile vomiting
• C. Blood in stools
• D. Failure to thrive

Correct answer: B

Rationale: The correct answer is B: Projectile vomiting. Pyloric stenosis in infants typically presents with projectile vomiting, which is forceful and projective in nature. This occurs due to the obstruction at the pylorus, leading to the stomach being unable to empty properly. Choices A, C, and D are incorrect. Bilious vomiting is more commonly associated with intestinal obstruction, blood in stools can occur in conditions such as necrotizing enterocolitis or allergic colitis, and failure to thrive is a nonspecific finding that can be seen in various pediatric conditions.

2. What is the priority assessment for a nurse when caring for an infant suspected of having necrotizing enterocolitis (NEC)?

• A. Hold feedings.
• B. Check gastric residuals before feedings.
• C. Take rectal temperature.
• D. Closely monitor abdominal distention.

Correct answer: D

Rationale: The correct answer is D: Closely monitor abdominal distention. Monitoring the abdomen for signs of distention is crucial in the early detection of necrotizing enterocolitis (NEC). In NEC, the bowel wall is edematous and breaking down, leading to abdominal distention. Holding feedings is important in the management of NEC, as feedings may need to be stopped temporarily. Checking gastric residuals before feedings helps in assessing the infant's tolerance to feedings. Taking rectal temperatures is contraindicated in NEC as it can lead to the perforation of the bowel.

3. Which laboratory value at the time of diagnosis should the nurse anticipate would determine the worst prognosis for a child with leukemia?

• A. Slow response to chemotherapy
• B. Platelets of 150,000/mcL
• C. Leukocytes less than 10,000/mcL
• D. Leukocytes of 275,000/mcL

Correct answer: D

Rationale: A high white blood cell count (leukocytes of 275,000/mcL) at diagnosis is associated with a worse prognosis in leukemia because it indicates a more aggressive disease with a higher tumor burden. Slow response to chemotherapy (choice A) is a consequence of the aggressive disease and not a determining factor at diagnosis. Platelets of 150,000/mcL (choice B) and leukocytes less than 10,000/mcL (choice C) are within normal ranges and not indicative of a worse prognosis in leukemia.

4. What is the appropriate method for measuring the temperature of a 2-day-old neonate?

• A. Tympanic
• B. Oral
• C. Axillary
• D. Rectal

Correct answer: C

Rationale: For a 2-day-old neonate, the most suitable method to measure temperature is the axillary method. This approach is considered safe and appropriate for neonates, minimizing the risk of injury. Tympanic temperature measurement may not be as accurate in neonates due to their small ear canals. Oral temperature measurement is not recommended for neonates as they may not be able to hold a thermometer properly in their mouths. Rectal temperature measurement is invasive and carries a higher risk of injury and should be avoided unless absolutely necessary.

5. What is most important in the management of cellulitis?

• A. Burow solution compresses
• B. Oral or parenteral antibiotics
• C. Topical application of an antibiotic
• D. Incision and drainage of severe lesions

Correct answer: B

Rationale: Oral or parenteral antibiotics are essential in treating cellulitis to eliminate the infection. Topical antibiotics are not sufficient, and incision and drainage are only for abscesses.
