CAT Exam Practice
1. A continuous infusion of nitroglycerin is prescribed for an adult male admitted with an acute myocardial infarction. The client is experiencing active chest pain that he describes as 8 out of 10. Which intervention is most important for the nurse to implement?
- A. Administer the infusion via an infusion pump
- B. Obtain the current serum potassium level
- C. Continuously monitor blood pressure
- D. Teach guided imagery to decrease pain
Correct answer: C
Rationale: Continuously monitoring blood pressure is crucial in this case because nitroglycerin can cause hypotension as a side effect. Monitoring blood pressure allows the nurse to assess the client's response to the medication and detect any signs of hypotension promptly. This intervention is essential to ensure the effectiveness of nitroglycerin therapy and prevent potential complications. Administering the infusion via an infusion pump is important for accurate dosing but not the most critical at this moment. Obtaining the current serum potassium level is important but not the most immediate concern when the client is experiencing active chest pain. Teaching guided imagery may be beneficial for pain management, but in this scenario, monitoring blood pressure takes precedence due to the potential side effects of nitroglycerin.
2. When caring for a client with borderline personality disorder, what is the most effective nursing intervention?
- A. Set clear and consistent boundaries for the client.
- B. Allow the client to vent their feelings without interruption.
- C. Encourage the client to participate in group therapy.
- D. Provide the client with frequent reassurance and support.
Correct answer: A
Rationale: Setting clear and consistent boundaries is essential when caring for a client with borderline personality disorder. This intervention helps provide structure, maintain a therapeutic relationship, and prevent manipulative behaviors. Allowing the client to vent feelings without interruption (Choice B) may not address the underlying issues effectively. Encouraging participation in group therapy (Choice C) can be beneficial but setting boundaries is more crucial. Providing frequent reassurance and support (Choice D) may inadvertently reinforce maladaptive behaviors instead of promoting growth and independence.
3. When reinforcing teaching and instructing the patient, which basic principle of teaching should you follow?
- A. Sequence the instruction from the least complex to the most complex.
- B. Assume that the patient knows little or nothing about the topic.
- C. Tell the patient to call their significant other so you can instruct them.
- D. Use medically oriented terms so the patient will be able to speak with the doctor.
Correct answer: A
Rationale: The correct principle of teaching to follow when reinforcing teaching and instructing the patient is to sequence the instruction from the least complex to the most complex. This approach facilitates learning by building upon simpler concepts before moving to more advanced ones. Choice B is incorrect because assuming the patient knows little or nothing about the topic may not always be accurate and can be patronizing. Choice C is incorrect as it does not focus on the direct teaching approach to the patient. Choice D is incorrect as using medically oriented terms may confuse the patient rather than facilitate understanding.
4. What is the primary goal in managing a child with cystic fibrosis?
- A. Increase dietary fat intake
- B. Prevent lung infections
- C. Increase physical activity
- D. Ensure high protein intake
Correct answer: B
Rationale: The primary goal in managing a child with cystic fibrosis is to prevent lung infections. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which increases the risk of infections. Preventing lung infections through proper respiratory care, medications, airway clearance techniques, and vaccinations is crucial in managing cystic fibrosis. While dietary interventions like increasing dietary fat intake, ensuring high protein intake, and promoting physical activity are also important aspects of cystic fibrosis management, preventing lung infections takes precedence as it directly addresses a major complication of the condition.
5. When caring for a child diagnosed with bronchiolitis, what is the priority nursing intervention?
- A. Administering bronchodilators
- B. Providing respiratory therapy
- C. Monitoring oxygen saturation
- D. Encouraging fluid intake
Correct answer: B
Rationale: The priority nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention aims to maintain airway patency, optimize oxygenation, and support effective breathing. Administering bronchodilators, though important, may not be the initial priority as respiratory therapy takes precedence in ensuring adequate oxygenation and ventilation. Monitoring oxygen saturation is crucial but is usually part of the ongoing assessment following the initiation of respiratory therapy. Encouraging fluid intake is essential for hydration but is not the priority intervention when addressing the respiratory distress associated with bronchiolitis.
