ATI RN
Cardiovascular System Practice Exam
1. What test uses sound waves to create images of the heart and assess its structure and function?
- A. Echocardiogram
- B. MRI
- C. CT scan
- D. X-ray
Correct answer: A
Rationale: An echocardiogram is the correct answer because it is a test specifically designed to use sound waves to create images of the heart, allowing healthcare providers to assess both its structure and function, as well as to detect any abnormalities. MRI (Choice B), CT scan (Choice C), and X-ray (Choice D) do not primarily use sound waves for imaging the heart; therefore, they are not the most appropriate choices for this scenario.
2. An RN is reviewing professional behavior expectations with a group of new nurses. Which of the following statements should be included in the teaching?
- A. It is not OK to discuss your days at work on social media.
- B. When you are passionate about a topic, speak up in professional platforms.
- C. Your behavior outside of the practice setting can impact your license.
- D. Nurses may lose their licenses for unprofessional actions.
Correct answer: D
Rationale: The correct statement to include in the teaching is that nurses may lose their licenses for unprofessional actions. This is an important reminder to new nurses about the serious consequences of unprofessional behavior in the healthcare field. Choice A is incorrect because discussing work on social media can breach patient confidentiality. Choice B is incorrect as speaking up in blogs and forums may not always align with professional conduct standards. Choice C is incorrect as behavior outside the practice setting, if unprofessional, can indeed impact a nurse's license.
3. A nurse provides dietary teaching to the guardian of a school-age child with cystic fibrosis. Which statement should the nurse make?
- A. You should offer your child high-protein meals and snacks throughout the day.
- B. You should decrease your child's dietary fat intake to less than 10% of their caloric intake.
- C. You should restrict your child's calorie intake to 1,200 per day.
- D. You should give your child a multivitamin once weekly.
Correct answer: A
Rationale: The correct answer is A. High-protein meals and snacks are essential for children with cystic fibrosis due to their increased nutritional needs. Protein helps in maintaining muscle mass and overall health in individuals with cystic fibrosis, making it crucial to include in their diet. Choices B, C, and D are incorrect because decreasing dietary fat intake to less than 10% of caloric intake, restricting calorie intake to 1,200 per day, and giving a multivitamin once weekly are not appropriate dietary recommendations for a child with cystic fibrosis.
4. A nurse is assessing a client who has heart failure and is receiving digoxin. Which of the following findings should the nurse identify as an indication of digoxin toxicity?
- A. Bradycardia.
- B. Tachycardia.
- C. Nausea.
- D. Blurred vision.
Correct answer: D
Rationale: Corrected Rationale: Blurred vision is a classic sign of digoxin toxicity, indicating a potential overdose. It is crucial to recognize this symptom promptly and report it to the healthcare provider for immediate intervention. Bradycardia and nausea are common side effects of digoxin but not specific indicators of toxicity. Tachycardia is unlikely in digoxin toxicity since it usually causes a decrease in heart rate.
5. A client has a chest tube. Which of the following interventions should the nurse include?
- A. Clamp the chest tube for 15 minutes every 2 hours.
- B. Maintain the drainage system below the client's chest.
- C. Strip the chest tube every 2 hours.
- D. Keep the collection device at the level of the client's chest.
Correct answer: B
Rationale: Maintaining the chest tube drainage system below the client's chest level is crucial to ensure proper drainage and prevent complications. Clamping the chest tube can lead to a tension pneumothorax, stripping the chest tube is an outdated practice that can cause damage to the tissues, and keeping the collection device at the level of the client's chest can impede proper drainage and lead to fluid accumulation.
