ATI Capstone Medical Surgical Assessment 2 Quizlet
1. What is the purpose of an escharotomy?
- A. To relieve pressure and improve circulation in burn injuries
- B. To reduce pain in the affected area
- C. To remove necrotic tissue from a wound
- D. To prevent infection from spreading
Correct answer: A
Rationale: An escharotomy is performed to relieve pressure and improve circulation in areas affected by deep burns. This procedure helps prevent complications such as compartment syndrome by releasing the constricting eschar. Choice B is incorrect because while pain relief may be a secondary outcome of the procedure, the primary purpose is to address pressure and circulation issues. Choice C is incorrect as an escharotomy specifically focuses on releasing pressure, not removing necrotic tissue. Choice D is incorrect as the primary goal of an escharotomy is not to prevent infection but rather to address the immediate issues related to deep burn injuries.
2. 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.
3. What are the expected symptoms in a patient with a thrombotic stroke?
- A. Gradual loss of function on one side of the body
- B. Sudden loss of consciousness
- C. Severe headache and confusion
- D. Loss of sensation in the affected limb
Correct answer: A
Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.
4. What ECG changes are associated with hyperkalemia?
- A. Flattened T waves
- B. ST depression
- C. Prominent U waves
- D. Elevated ST segments
Correct answer: B
Rationale: Hyperkalemia is known to cause ST depression on an ECG. Flattened T waves are more commonly seen in hypokalemia. Prominent U waves are associated with hypokalemia rather than hyperkalemia. Elevated ST segments are not typical findings in hyperkalemia.
5. A patient with GERD is receiving dietary teaching from a nurse. What should the nurse recommend?
- A. Avoid mint and pepper
- B. Increase fluid intake before meals
- C. Eat three large meals per day
- D. Avoid drinking water with meals
Correct answer: A
Rationale: The correct recommendation for a patient with GERD is to avoid foods like mint and pepper, as these can help reduce gastric acid secretion and alleviate symptoms. Mint and pepper are known to relax the lower esophageal sphincter, leading to increased reflux. Increasing fluid intake before meals (choice B) may worsen GERD symptoms by distending the stomach. Eating three large meals per day (choice C) can also aggravate GERD because large meals can lead to increased gastric pressure and reflux. Avoiding drinking water with meals (choice D) is generally recommended for GERD; however, the most crucial advice in this case is to avoid mint and pepper for better symptom management.
