ATI Capstone Medical Surgical Assessment 2 Quizlet
1. What are the expected ECG changes in hypokalemia?
- A. Flattened T waves
- B. ST elevation
- C. Wide QRS complex
- D. Tall T waves
Correct answer: A
Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.
2. What is the first-line treatment for wheezing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Cromolyn via nebulizer
- C. Methylprednisolone 100 mg IV
- D. Aminophylline 500 mg IV
Correct answer: A
Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it acts quickly to open the airways by relaxing the muscles in the air passages. Cromolyn (Choice B) is used for asthma prevention rather than acute wheezing. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in the setting of an allergic reaction.
3. What does continuous bubbling in the water seal chamber of a chest tube indicate?
- A. An air leak
- B. A blockage in the chest tube
- C. Normal chest tube function
- D. Malfunction in the drainage system
Correct answer: A
Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This bubbling occurs when air is escaping through the tube and entering the water seal chamber. Choice B, a blockage in the chest tube, is incorrect as continuous bubbling does not suggest a blockage. Choice C, normal chest tube function, is incorrect because continuous bubbling is not an expected finding in a properly functioning chest tube. Choice D, a malfunction in the drainage system, is incorrect as continuous bubbling specifically points towards an air leak, not a general malfunction.
4. After a healthcare provider misreads a glucose level and administers insulin, what is the priority intervention?
- A. Monitor for hypoglycemia
- B. Administer glucose IV
- C. Document the incident
- D. Monitor for hyperglycemia
Correct answer: A
Rationale: The correct answer is to monitor for hypoglycemia. Administering insulin based on a misread glucose level can lead to hypoglycemia. Monitoring for hypoglycemia is crucial as it is a potential adverse effect of the insulin administration. Administering glucose IV (Choice B) is not the priority as there is no indication of hypoglycemia yet. Documenting the incident (Choice C) is important but not the immediate priority over patient safety. Monitoring for hyperglycemia (Choice D) is not the priority after administering insulin in response to a misread glucose level.
5. What recommendations should the nurse provide to a patient diagnosed with GERD?
- A. Avoid items like mint that increase gastric acid secretion
- B. Eat small, frequent meals
- C. Avoid eating 1 hour before bedtime
- D. Avoid black and red pepper
Correct answer: A
Rationale: The correct answer is A: 'Avoid items like mint that increase gastric acid secretion.' Mint can relax the lower esophageal sphincter, leading to increased gastric acid secretion and worsening GERD symptoms. Choice B is a good recommendation for GERD management as it helps prevent excessive stomach distension. Choice C is also a recommended practice to avoid reflux during sleep. Choice D, avoiding black and red pepper, is not directly linked to exacerbating GERD symptoms, so it is not the most relevant recommendation for a patient diagnosed with GERD.
