ATI Capstone Medical Surgical Assessment 2 Quizlet
1. What precaution should be advised to patients following cataract surgery?
- A. Wear dark glasses while outdoors
- B. Use warm compresses
- C. Avoid NSAIDs
- D. Avoid bright lights
Correct answer: A
Rationale: Patients who have undergone cataract surgery should wear dark glasses when outdoors to shield their eyes from light exposure, which can be uncomfortable or harmful during the recovery period. Using warm compresses (choice B) is not typically recommended after cataract surgery as it's more relevant for certain eye conditions. Avoiding NSAIDs (choice C) is advised to prevent bleeding complications, but it is not directly related to eye protection post-surgery. While avoiding bright lights (choice D) is crucial, wearing dark glasses provides a practical solution to achieve this, making choice A the most appropriate precaution.
2. What ECG change is associated with hyperkalemia?
- A. Flattened T waves
- B. ST depression
- C. Prominent U waves
- D. Elevated ST segments
Correct answer: B
Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.
3. A nurse in an emergency department is caring for a client who has sustained multiple injuries. The nurse observes the client's thorax moving inward during inspiration and outward during expiration. The nurse should suspect which of the following injuries?
- A. Flail chest
- B. Hemothorax
- C. Pulmonary contusion
- D. Pneumothorax
Correct answer: A
Rationale: The correct answer is A: Flail chest. Flail chest results from multiple rib fractures, causing paradoxical chest movement where the injured part moves inward during inspiration and outward during expiration, interfering with ventilation. Choice B, Hemothorax, involves blood in the pleural cavity and does not typically cause paradoxical chest movement. Choice C, Pulmonary contusion, is a bruise to the lung tissue and does not present with paradoxical chest movement. Choice D, Pneumothorax, is the presence of air in the pleural space, leading to lung collapse, but it does not demonstrate paradoxical chest movement like in flail chest.
4. What should a healthcare professional monitor for in a patient with compartment syndrome?
- A. Unrelieved pain, pallor, and pulselessness
- B. Localized redness and swelling
- C. Fever and signs of infection
- D. Loss of deep tendon reflexes
Correct answer: A
Rationale: Unrelieved pain, pallor, and pulselessness are classic signs of compartment syndrome. In this condition, increased pressure within a muscle compartment impairs blood flow, leading to severe pain that is not relieved by usual measures, pallor from decreased blood flow, and pulselessness due to compromised circulation. These signs indicate a medical emergency requiring immediate intervention. Localized redness and swelling (Choice B) are more characteristic of inflammation or infection rather than compartment syndrome. Fever and signs of infection (Choice C) are not typical manifestations of compartment syndrome. Loss of deep tendon reflexes (Choice D) is associated with conditions affecting the nervous system, not compartment syndrome.
5. What intervention is required when continuous bubbling is seen in the chest tube water seal chamber?
- A. Tighten the connections of the chest tube system
- B. Clamp the chest tube
- C. Replace the chest tube
- D. Continue monitoring the chest tube
Correct answer: A
Rationale: When continuous bubbling is observed in the chest tube water seal chamber, tightening the connections of the chest tube system is the appropriate intervention. This action can often resolve an air leak, which is the common cause of continuous bubbling. Clamping the chest tube or replacing it is not recommended as the first-line intervention because it may lead to complications or unnecessary tube changes. Continuing to monitor the chest tube without addressing the air leak would delay necessary corrective action, potentially causing respiratory compromise in the patient. Therefore, tightening the connections of the chest tube system is the most suitable initial step to manage continuous bubbling in the water seal chamber.
