RN Nursing Care of Children 2019 With NGN
1. A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a “trigger” results in which of these manifestations?
- A. Bronchodilation, muscle relaxation, and decreased mucus production
- B. Air trapping and hypo-inflation of the alveoli
- C. Air trapping and decreased blood flow to the upper airway
- D. Bronchoconstriction, airway inflammation, and excess mucus production
Correct answer: D
Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.
2. An infant requires surgery for repair of a cleft lip. An important priority of the preoperative nursing care is which?
- A. Initiating discharge teaching
- B. Performing baseline physical and behavioral assessment
- C. Observing for allergic reactions to preoperative antibiotics
- D. Determining whether this defect exists in other family members
Correct answer: B
Rationale: Performing a baseline physical and behavioral assessment is crucial to determine the infant's current health status and to identify any potential risks before surgery.
3. What is a primary consideration for complications when planning nursing care for an infant with Meconium aspiration syndrome?
- A. Hypoglycemia
- B. Bowel obstruction
- C. Airway obstruction
- D. Carbon dioxide retention
Correct answer: C
Rationale: The correct answer is C: Airway obstruction. When planning nursing care for an infant with Meconium aspiration syndrome, a primary consideration for complications is the potential of airway obstruction. After the passage of meconium into the amniotic fluid, the infant may inhale or swallow the fluid, leading to meconium aspiration into the lower airways and causing a partial airway obstruction. This can result in respiratory distress and hypoxemia. Hypoglycemia (choice A) is a metabolic condition unrelated to meconium aspiration. Bowel obstruction (choice B) with meconium may indicate other conditions like cystic fibrosis or Hirschsprung disease, not directly related to meconium aspiration syndrome. Carbon dioxide retention (choice D) is not a primary consideration in meconium aspiration syndrome; instead, the focus is on addressing the airway obstruction and potential respiratory compromise.
4. Which disease requires strict isolation due to its mode of transmission?
- A. Mumps
- B. Chickenpox
- C. Exanthema subitum (roseola)
- D. Erythema infectiosum (fifth disease)
Correct answer: B
Rationale: The correct answer is Chickenpox (choice B). Chickenpox is highly communicable and requires strict isolation to prevent the spread of the virus through direct contact, droplet transmission, and contaminated objects. Mumps (choice A) is also contagious but does not typically require strict isolation. Exanthema subitum (roseola) (choice C) and Erythema infectiosum (fifth disease) (choice D) are not as highly contagious as chickenpox and do not necessitate strict isolation.
5. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?
- A. Tetralogy of Fallot
- B. Coarctation of the aorta
- C. Transposition of the great arteries
- D. Ventricular septal defect
Correct answer: A
Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.
