1. What explanation should the nurse provide to the parents of a 6-month-old infant diagnosed with cystic fibrosis?
- A. It is a condition affecting the respiratory and digestive systems.
- B. It is an autoimmune disorder affecting multiple organs.
- C. It is a genetic disorder that can be managed with medication.
- D. It is a condition caused by prenatal exposure to toxins.
Correct answer: A
Rationale: The correct answer is A. Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It results in the production of thick, sticky mucus that can clog the lungs and obstruct the pancreas. This explanation is crucial for parents to understand the impact of the condition on their child's health. Choice B is incorrect because cystic fibrosis is not an autoimmune disorder. Choice C is partially correct in that cystic fibrosis is a genetic disorder, but it requires a comprehensive management approach beyond just medication. Choice D is incorrect as cystic fibrosis is not caused by prenatal exposure to toxins but rather by inheriting specific genetic mutations.
2. The parents of a child who is scheduled for open-heart surgery ask why their child must be subjected to chest tubes after surgery. What should the nurse consider before responding in language the parents will understand?
- A. They will increase tidal volumes.
- B. Drainage of air and fluid will be facilitated.
- C. They will maintain positive intrapleural pressure.
- D. Pressure on the pericardium and chest wall will be regulated.
Correct answer: B
Rationale: Chest tubes are used to drain air and fluid from the chest cavity to prevent complications such as pneumothorax or cardiac tamponade after surgery. Choice A is incorrect as chest tubes are not used to increase tidal volumes. Choice C is incorrect as chest tubes do not maintain positive intrapleural pressure; instead, they assist in removing excess air or fluid. Choice D is incorrect as chest tubes do not regulate pressure on the pericardium and chest wall; they primarily aid in drainage.
3. What should be taught to the child and parents about using a peak flow meter for a child diagnosed with asthma?
- A. Use the device before taking medication
- B. Use the device during asthma attacks
- C. Record the best of three attempts
- D. Use the device after eating
Correct answer: C
Rationale: The correct answer is to 'Record the best of three attempts.' This method provides an accurate measure of peak expiratory flow using a peak flow meter. By taking the best of three attempts, the child and parents can obtain a more reliable assessment of the child's lung function. Choices A, B, and D are incorrect because using the device before taking medication, during asthma attacks, or after eating does not ensure an accurate measurement of peak flow, which is essential for managing asthma effectively. Monitoring peak flow regularly and accurately can help in adjusting asthma treatment plans and assessing response to medications.
4. What is an important nursing responsibility when a dysrhythmia is suspected?
- A. order an immediate electrocardiogram
- B. count the radial pulse every 1 minute for five times
- C. count the apical pulse for 1 full minute, and compare the rate with the radial pulse rate
- D. have someone else take the radial pulse simultaneously with the apical pulse
Correct answer: C
Rationale: When a dysrhythmia is suspected, an important nursing responsibility is to count the apical pulse for 1 full minute and then compare this rate with the radial pulse rate. This method helps in identifying dysrhythmias as it allows for a direct comparison of the heart's rhythm at two different pulse points. Ordering an immediate electrocardiogram (Choice A) may be necessary but should not be the first step. Counting the radial pulse multiple times (Choice B) is not as accurate as comparing rates directly. Having someone else take the radial pulse simultaneously (Choice D) may introduce errors and inconsistencies in the measurement.
5. A premature infant with respiratory distress syndrome (RDS) receives artificial surfactant. How does the nurse explain surfactant therapy to the parents?
- A. Surfactant improves the ability of your baby’s lungs to exchange oxygen and carbon dioxide.
- B. The drug prevents your baby from requiring excessive sedation.
- C. Surfactant is used to reduce episodes of periodic apnea.
- D. Your baby needs this medication to combat a potential respiratory tract infection.
Correct answer: A
Rationale: The correct answer is A. Surfactant therapy is explained to parents as a treatment that enhances the lungs' ability to exchange oxygen and carbon dioxide. This is essential for premature infants with respiratory distress syndrome (RDS) as it helps improve their respiratory function. Choices B, C, and D are incorrect because surfactant therapy primarily focuses on addressing lung function and is not related to sedation, apnea reduction, or fighting respiratory tract infections.
