Nursing Elites

1. What is the expected ECG finding in a patient with hypokalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Widened QRS complexes
• D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

2. 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.

3. A nurse is caring for a client with rheumatoid arthritis who has been taking prednisone. Which of the following findings should the nurse identify as an adverse effect of this medication?

• A. Weight loss
• B. Hypoglycemia
• C. Hypertension
• D. Hyperkalemia

Correct answer: C

Rationale: The correct answer is C, 'Hypertension.' Prednisone, a corticosteroid, can lead to hypertension as an adverse effect. Prednisone can cause sodium retention and potassium loss, leading to increased blood pressure. Weight loss (choice A) is not a common adverse effect of prednisone; in fact, weight gain is more common. Hypoglycemia (choice B) is not typically associated with prednisone use; instead, hyperglycemia is a common concern. Hyperkalemia (choice D) is also unlikely with prednisone use; instead, hypokalemia is a potential electrolyte imbalance.

4. What is the first intervention for a patient admitted with unstable angina?

• A. Administer nitroglycerin
• B. Obtain cardiac enzymes
• C. Start IV fluids
• D. Monitor for chest pain

Correct answer: A

Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.

5. What is the first nursing action for a patient admitted with chest pain from acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Check the patient's urine output
• C. Administer IV fluids
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This is the priority action for a patient admitted with chest pain from acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improve blood flow to the heart, and relieve chest pain. Checking the patient's urine output (Choice B) is not the priority in this situation. Administering IV fluids (Choice C) may not be necessary unless indicated by the patient's condition. Obtaining cardiac enzymes (Choice D) is important but is not the initial action needed to address the patient's acute symptoms.
