1. An 8-year-old child diagnosed with meningitis is to undergo a lumbar puncture. What should the nurse explain is the purpose of this procedure?
- A. To measure the pressure of cerebrospinal fluid
- B. To obtain a sample of cerebrospinal fluid for analysis
- C. To relieve intracranial pressure
- D. To assess the presence of infection in the spinal fluid
Correct answer: B
Rationale: A lumbar puncture is performed to obtain a sample of cerebrospinal fluid for analysis. This fluid is then examined for signs of infection, bleeding, or other abnormalities. Measuring the pressure of cerebrospinal fluid is typically done during the procedure itself, but it is not the primary purpose of the lumbar puncture. While a lumbar puncture can indirectly help relieve intracranial pressure by removing excess cerebrospinal fluid, this is not its primary purpose. Assessing the presence of infection in the spinal fluid is part of the analysis that follows the collection of the sample, making it a secondary outcome of the procedure.
2. Why does a cleft lip predispose an infant to infection?
- A. Waste products accumulate along the defect.
- B. There is evidence of inadequate circulation in the defective area.
- C. Nutrition is inadequate due to ineffective feeding.
- D. Mouth breathing dries the oropharyngeal mucous membranes.
Correct answer: D
Rationale: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.
3. The healthcare provider notes that a child has lost 8 pounds after 4 days of hospitalization for acute glomerulonephritis. This is most likely the result of
- A. poor appetite
- B. increased potassium intake
- C. reduction of edema
- D. restriction to bed rest
Correct answer: C
Rationale: In acute glomerulonephritis, weight loss is most likely due to the reduction of edema. Edema is a common symptom of glomerulonephritis, which causes fluid retention and swelling in the body. As treatment progresses and the condition improves, the reduction of edema leads to weight loss. Choices A, B, and D are incorrect as they do not directly address the underlying pathophysiology of acute glomerulonephritis and its impact on weight loss.
4. What is the nurse’s priority intervention when preparing for admission of a child with acute laryngotracheobronchitis?
- A. Pad the side rails of the crib.
- B. Arrange for a quiet, cool room.
- C. Place a tracheotomy set at the bedside.
- D. Obtain a recliner so that a parent can stay.
Correct answer: C
Rationale: The correct answer is to place a tracheotomy set at the bedside. Acute laryngotracheobronchitis can cause airway obstruction, which may require an emergency tracheotomy. Having the tracheotomy set readily available ensures quick access in case of respiratory distress. Padding the side rails of the crib, arranging for a quiet, cool room, and obtaining a recliner for a parent are important aspects of care but are not the priority when managing a potentially life-threatening airway emergency.
5. A child with a diagnosis of cystic fibrosis is admitted to the hospital. What is the priority nursing intervention?
- A. Administering pancreatic enzymes
- B. Providing respiratory therapy
- C. Providing nutritional support
- D. Encouraging physical activity
Correct answer: A
Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.
