ATI Capstone Adult Medical Surgical Assessment 2
1. 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.
2. What teaching should be provided to a patient following surgical removal of a cataract?
- A. Avoid NSAIDs
- B. Wear dark glasses while outdoors
- C. Creamy white drainage is normal
- D. Reduce phosphorus intake to 700 mg/day
Correct answer: A
Rationale: The correct teaching to provide to a patient following surgical removal of a cataract is to avoid NSAIDs. NSAIDs can increase the risk of bleeding at the surgical site, so it is important to steer clear of them. Choice B, wearing dark glasses while outdoors, may be recommended post-surgery to protect the eyes from bright light, but it is not the priority teaching in this case. Choice C, stating that creamy white drainage is normal, is not accurate as drainage from the eye should be monitored and reported. Choice D, reducing phosphorus intake to 700 mg/day, is unrelated to post-cataract surgery care and is not a necessary teaching point.
3. What should the nurse monitor for in a patient with hypokalemia?
- A. Monitor for muscle weakness
- B. Check deep tendon reflexes (DTRs)
- C. Monitor for seizures
- D. Monitor for bradycardia
Correct answer: A
Rationale: The correct answer is to monitor for muscle weakness in a patient with hypokalemia. Hypokalemia, which is low potassium levels, can lead to muscle weakness due to its effects on neuromuscular function. Checking deep tendon reflexes (Choice B) is not typically associated with hypokalemia. Seizures (Choice C) are more commonly associated with low calcium levels rather than low potassium levels. Bradycardia (Choice D) is a symptom of hyperkalemia (high potassium levels) rather than hypokalemia.
4. A patient is admitted with chest pain, possible acute coronary syndrome. What should the nurse do first?
- A. Administer sublingual nitroglycerin
- B. Get IV access
- C. Obtain cardiac enzymes
- D. Auscultate heart sounds
Correct answer: A
Rationale: In a patient with chest pain, possible acute coronary syndrome, the nurse should administer sublingual nitroglycerin first. Nitroglycerin helps to vasodilate coronary arteries, improving blood flow to the heart, and reducing cardiac workload. This can alleviate chest pain and decrease cardiac tissue damage in acute coronary syndrome. Getting IV access, obtaining cardiac enzymes, and auscultating heart sounds are important steps in the assessment and management of acute coronary syndrome, but administering nitroglycerin to relieve chest pain and improve blood flow takes precedence as it directly addresses the patient's symptoms and aims to prevent further cardiac damage.
5. A patient with a chest tube has continuous bubbling in the water seal chamber. What does this indicate?
- A. An air leak
- B. A blocked chest tube
- C. Drainage from the site
- D. Blood clot in the chest tube
Correct answer: A
Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This situation requires immediate attention to prevent complications such as lung collapse. A blocked chest tube would typically result in absent or fluctuating bubbling. Drainage from the site would be observed in the collection chamber, not the water seal chamber. A blood clot in the chest tube would lead to cessation of drainage.
