Nursing Elites

1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?

• A. Colonoscopy
• B. Rectal biopsy
• C. Multiple saline enemas
• D. Fiberoptic nasoenteric tube

Correct answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.

2. How should you care for an alert 4-year-old child with a mild airway obstruction, who has respiratory distress, a strong cough, and normal skin color?

• A. Back blows, abdominal thrusts, transport
• B. Oxygen, avoiding agitation, transport
• C. Assisting ventilations, back blows, transport
• D. Chest thrusts, finger sweeps, transport

Correct answer: B

Rationale: The correct approach for an alert 4-year-old child with a mild airway obstruction, respiratory distress, a strong cough, and normal skin color is to provide oxygen, avoid agitation, and arrange for transport. Oxygen helps support breathing, avoiding agitation prevents worsening of the obstruction, and transport ensures the child receives further medical evaluation and treatment. Choices A, C, and D involve techniques that are not recommended for a mild airway obstruction in this scenario. Back blows, abdominal thrusts, chest thrusts, and finger sweeps are interventions used for different situations and not suitable for a child with the described symptoms.

3. .The parents of a 6-week-old infant who was born without an immune system ask a nurse why their baby is still so healthy. How should the nurse reply?

• A. Exposure to pathogens during this time can be limited.
• B. Some antibodies are produced by the infant’s colonic bacteria.
• C. Antibodies are passively received from the mother through the placenta and breast milk.
• D. Fewer antibodies are produced by the fetal thymus during the eighth and ninth months of gestation.

Correct answer: C

Rationale: Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially.

4. A 13-year-old girl tells the nurse at the pediatric clinic that she took a pregnancy test and it was positive. She adds that her grandfather, with whom she, her younger sisters, and her mother live, has repeatedly molested her for the past 3 years. When the nurse asks the girl if she has told this to anyone, she replies, 'Yes, but my mother doesn’t believe me.' Legally, who should the nurse notify?

• A. Police regarding a possible sex crime
• B. Healthcare provider to confirm the pregnancy
• C. Child Protective Services for immediate intervention
• D. Girl’s mother about the positive pregnancy test result

Correct answer: C

Rationale: In this scenario, the nurse should notify Child Protective Services for immediate intervention. The girl disclosed ongoing sexual abuse by her grandfather, which is a serious concern requiring immediate protection and intervention by the appropriate authorities. Child Protective Services are trained to handle cases of child abuse and neglect, ensuring the safety and well-being of the child. While notifying the police about a possible sex crime is crucial, Child Protective Services should be the first point of contact in cases of suspected child abuse due to their specialized role. Confirming the pregnancy through a healthcare provider is not the priority at this moment, as ensuring the safety of the child is paramount. Informing the girl's mother about the positive test result is not appropriate given the lack of belief in the abuse disclosure and the potential risk to the child's safety.

5. You are managing a 10-month-old infant who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. You have initiated supplemental oxygen therapy and elevated the lower extremities. En route to the hospital, you note that the child's work of breathing has increased. What must you do first?

• A. Lower the extremities and reassess the child
• B. Begin positive pressure ventilations and reassess the child
• C. Place a nasopharyngeal airway and increase the oxygen flow
• D. Listen to the lungs with a stethoscope for abnormal breath sounds

Correct answer: A

Rationale: In this scenario, the infant is showing signs of shock with increased work of breathing. Lowering the extremities helps improve venous return to the heart, cardiac output, and oxygenation by reducing the pressure on the diaphragm. This action can alleviate the respiratory distress and is a critical step to take in a child with signs of shock. Beginning positive pressure ventilations (Choice B) should be considered if the infant's respiratory distress worsens despite lowering the extremities. Placing a nasopharyngeal airway and increasing oxygen flow (Choice C) may not directly address the increased work of breathing or the underlying shock condition. Listening to the lungs with a stethoscope (Choice D) may provide information on lung sounds but does not address the immediate need to improve breathing in a child with signs of shock.
