1. A 7-year-old child with cystic fibrosis is admitted to the hospital with a respiratory infection. The nurse is teaching the child’s parents about the importance of chest physiotherapy (CPT). Which statement by the parents indicates they need further teaching?
- A. We should perform CPT before meals.
- B. CPT will help loosen mucus in the lungs.
- C. We should perform CPT right after the child eats.
- D. CPT is an important part of our child’s treatment.
Correct answer: C
Rationale: The correct answer is C. Chest physiotherapy should not be performed right after meals to avoid inducing vomiting. It should be done before meals or at least 1 hour after for effective mucus clearance and to prevent any potential complications like vomiting. Choice A is correct as performing CPT before meals helps in loosening mucus. Choice B is also correct as CPT is indeed helpful in loosening mucus in the lungs. Choice D is correct as CPT plays a crucial role in the treatment of cystic fibrosis.
2. A two-year-old child with heart failure is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?
- A. Determine the pulse deficit.
- B. Administer the scheduled dose.
- C. Calculate the safe dose range.
- D. Review the serum digoxin level.
Correct answer: B
Rationale: Administering the scheduled dose is appropriate in this scenario as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is within the acceptable range. Calculating the safe dose range (Choice C) is not needed since the heart rate is already within the expected parameters. Reviewing the serum digoxin level (Choice D) is not the immediate action required in this case where the heart rate is within the normal range.
3. In a 6-year-old child with asthma experiencing difficulty breathing and using accessory muscles to breathe with a peak flow reading in the red zone, what should the nurse do first?
- A. Administer a nebulized bronchodilator
- B. Obtain an arterial blood gas
- C. Start the child on oxygen therapy
- D. Contact the healthcare provider
Correct answer: A
Rationale: The correct action for a 6-year-old child with asthma who is experiencing difficulty breathing, using accessory muscles to breathe, and has a peak flow reading in the red zone is to administer a nebulized bronchodilator first. Nebulized bronchodilators work rapidly to open up the airways, providing immediate relief and improving breathing. This intervention is crucial in addressing the acute respiratory distress the child is facing. Obtaining an arterial blood gas, starting oxygen therapy, or contacting the healthcare provider can be considered after the initial administration of the bronchodilator, as they are not the primary interventions needed to manage the child's acute respiratory distress.
4. A mother brings her 2-year-old son to the clinic because he has been crying and pulling on his earlobe for the past 12 hours. The child’s oral temperature is 101.2°F. Which intervention should the nurse implement?
- A. Ask the mother if the child has had a runny nose
- B. Cleanse purulent exudate from the affected ear canal
- C. Apply a topical antibiotic to the periauricle area
- D. Provide parent education to prevent recurrence
Correct answer: A
Rationale: In a child with ear pain and fever, asking about a runny nose is important to assess if the ear pain is associated with a respiratory infection, such as otitis media. This information can guide further assessment and treatment decisions. Choice B is incorrect because cleansing purulent exudate should be done by a healthcare provider, not the nurse. Choice C is incorrect as topical antibiotics should only be applied under healthcare provider's orders. Choice D is not the priority at this moment, as the immediate concern is assessing the association between the ear pain and a possible respiratory infection.
5. A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?
- A. Metabolic acidosis
- B. Respiratory acidosis
- C. Respiratory alkalosis
- D. Metabolic alkalosis
Correct answer: C
Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.
