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.

What intervention is crucial during a sickle cell crisis in a child?
- A. Administer oxygen
- B. Apply cold compresses
- C. Restrict fluids
- D. Encourage bed rest
Correct Answer: A
Rationale: Administering oxygen is crucial during a sickle cell crisis in a child as it helps to prevent further sickling of cells. Oxygen therapy can improve oxygen saturation levels, reducing the risk of tissue damage and complications. Applying cold compresses (choice B) is not recommended as it can potentially worsen vaso-occlusive crisis by causing vasoconstriction. Restricting fluids (choice C) is not appropriate as hydration is essential to prevent dehydration and maintain adequate blood flow. Encouraging bed rest (choice D) may be necessary but administering oxygen takes precedence in managing a sickle cell crisis.
What is an essential nursing care intervention for a neonate with a suspected tracheoesophageal fistula?
- A. Feed glucose water only.
- B. Elevate the patient's head for feedings.
- C. Raise the patient's head and give nothing by mouth.
- D. Avoid suctioning unless the infant is cyanotic.
Correct Answer: C
Rationale: Raising the patient's head and giving nothing by mouth is crucial in managing tracheoesophageal fistula. This intervention helps prevent aspiration and further complications until surgical correction can be performed. Feeding the neonate or suctioning could exacerbate the condition by risking aspiration. Elevating the head for feedings does not address the primary concern of preventing oral intake, making it less appropriate than the correct answer.
The nurse is preparing to care for a newborn with an omphalocele. The nurse should understand that care of the infant should include what intervention?
- A. Initiating breast or bottle-feedings to stabilize the blood glucose level
- B. Maintaining pain management with an intravenous opioid
- C. Covering the intact bowel with a nonadherent dressing to prevent injury
- D. Performing immediate surgery
Correct Answer: C
Rationale: The priority intervention for an infant with an omphalocele is to cover the intact bowel with a nonadherent dressing to protect the exposed organs and prevent infection. This intervention is crucial to prevent injury and maintain the infant's safety. Initiating feedings or maintaining pain management are not the immediate priorities in the care of an infant with an omphalocele. Performing immediate surgery may be required in the future, but initially, covering the bowel is the first critical step in management.
What is the most appropriate action for a healthcare provider if a child presents with suspected meningitis?
- A. Administer antibiotics immediately
- B. Perform a lumbar puncture
- C. Isolate the child
- D. Obtain a complete blood count
Correct Answer: C
Rationale: Isolating the child is a priority to prevent the spread of infection until meningitis is confirmed or ruled out. Meningitis, particularly bacterial, is highly contagious and can lead to outbreaks if not properly managed. Isolation and prompt treatment are critical in preventing serious complications. Administering antibiotics immediately without confirmation of the diagnosis can be harmful if the cause is viral or non-infectious. Performing a lumbar puncture is a diagnostic procedure that should be done by a healthcare provider but is not the initial action when suspecting meningitis. Obtaining a complete blood count may be part of the diagnostic workup but is not the most appropriate initial action in suspected meningitis.
Which of the following conditions is characterized by a 'machine-like' murmur in children?
- A. Patent ductus arteriosus
- B. Ventricular septal defect
- C. Atrial septal defect
- D. Coarctation of the aorta
Correct Answer: A
Rationale: The correct answer is A, Patent ductus arteriosus. This condition is characterized by a continuous 'machine-like' murmur due to abnormal blood flow between the aorta and pulmonary artery. Ventricular septal defect (choice B) is characterized by a harsh holosystolic murmur, atrial septal defect (choice C) typically presents with a fixed split S2 and a pulmonary flow murmur, and coarctation of the aorta (choice D) is associated with a systolic murmur in the back and bilateral lower extremities.
