Nursing Elites

1. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

2. 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.

3. What is the most likely cause of continuous bubbling in the water seal chamber of a chest tube?

• A. An air leak
• B. A blockage in the chest tube
• C. Normal chest tube function
• D. Drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube usually indicates an air leak. An air leak can disrupt the negative pressure required for the chest tube to function properly, leading to inadequate drainage and potential complications. A blockage in the chest tube would typically result in decreased or absent drainage rather than continuous bubbling. Normal chest tube function does not involve continuous bubbling in the water seal chamber. Drainage from the chest tube may lead to fluid moving into the drainage system, but it would not cause continuous bubbling in the water seal chamber.

4. A nurse is providing discharge teaching to a client who is starting to take carbidopa/levodopa to treat Parkinson's disease. Which of the following instructions should the nurse include in the teaching?

• A. This medication can cause your urine to turn a dark color.
• B. Expect immediate relief after taking this medication.
• C. Take the medication with a high protein food.
• D. Skip a dose of the medication if you experience dizziness.

Correct answer: A

Rationale: The correct instruction to include in the teaching is that carbidopa/levodopa can cause the client's urine to turn a dark color, which is a harmless effect. It is crucial for the nurse to educate the client about this common side effect. Choice B is incorrect because immediate relief is not expected; therapeutic effects may take weeks to months. Choice C is incorrect as carbidopa/levodopa should be taken on an empty stomach to enhance absorption. Choice D is incorrect as the client should not skip doses without consulting their healthcare provider, even if they experience dizziness.

5. A nurse is planning care for a patient diagnosed with diabetes insipidus. What should be included in the care plan?

• A. Monitor serum albumin levels
• B. Restrict protein intake to 0.55-0.60 g/kg/day
• C. Encourage the patient to increase fluid intake
• D. Teach the patient to avoid alcohol

Correct answer: A

Rationale: The correct answer is to monitor serum albumin levels. In patients with diabetes insipidus, monitoring serum albumin levels is essential to assess for dehydration and nutritional deficits. Choices B, C, and D are not directly related to managing diabetes insipidus. Restricting protein intake, encouraging fluid intake, and teaching the patient to avoid alcohol are interventions that may be relevant for other medical conditions but are not specific to addressing the needs of a patient with diabetes insipidus.
