What is typically the first sign of puberty in females?
- A. Breast development
- B. Menarche
- C. Pubic hair growth
- D. Axillary hair growth
Correct Answer: A
Rationale: The correct answer is A: Breast development (thelarche) is usually the first sign of puberty in females, typically beginning between ages 8 and 13. This marks the start of puberty, followed by pubic hair growth, a growth spurt, and eventually menarche (the onset of menstruation). Pubic hair growth and axillary hair growth usually follow breast development in the sequence of pubertal changes. Therefore, the first noticeable change indicating the onset of puberty in females is the development of breast buds.

Which condition is characterized by a harsh, barking cough in children?
- A. Asthma
- B. Bronchiolitis
- C. Croup
- D. Pneumonia
Correct Answer: C
Rationale: Croup is the correct answer. It is characterized by a harsh, barking cough due to inflammation of the upper airways, specifically the larynx and trachea. Asthma (Choice A) often presents with wheezing and shortness of breath, not a barking cough. Bronchiolitis (Choice B) typically causes wheezing and respiratory distress in infants. Pneumonia (Choice D) manifests with symptoms such as fever, productive cough, and chest pain, but not usually a barking cough.
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.
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.
An infant with short bowel syndrome will be on total parenteral nutrition (TPN) for an extended period of time. What should the nurse monitor the infant for?
- A. Central venous catheter infection, electrolyte losses, and hyperglycemia
- B. Hypoglycemia, catheter migration, and weight gain
- C. Venous thrombosis, hyperlipidemia, and constipation
- D. Catheter damage, red currant jelly stools, and hypoglycemia
Correct Answer: A
Rationale: Infants with short bowel syndrome requiring prolonged total parenteral nutrition (TPN) are susceptible to central venous catheter infections, electrolyte losses, and hyperglycemia. Monitoring for these complications is crucial to prevent serious outcomes. Choices B, C, and D are incorrect because they do not reflect the common complications associated with prolonged TPN in infants.
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.
