Nursing Elites

1. A nurse is caring for four clients. The nurse should observe which of the following clients for a risk of vitamin B6 deficiency?

• A. A client who has cystic fibrosis
• B. A client who has chronic alcohol use disorder
• C. A client who takes phenytoin for a seizure disorder
• D. A client who is prescribed rifampin for tuberculosis

Correct answer: B

Rationale: Chronic alcohol use disorder can lead to vitamin B6 deficiency due to impaired absorption and increased excretion of the vitamin. While clients with cystic fibrosis may be at risk for fat-soluble vitamin deficiencies, such as vitamins A, D, E, and K, they are not specifically at high risk for vitamin B6 deficiency. Clients taking phenytoin are at risk for folate deficiency, not vitamin B6. Clients prescribed rifampin for tuberculosis are at risk for vitamin D deficiency, not vitamin B6.

2. A client is receiving teaching about a high-fiber diet to manage constipation. Which statement indicates the best choice for a high-fiber diet?

• A. Eating one medium apple is a good snack option.
• B. Selecting a ½ cup of sweet potatoes for starch is a great choice.
• C. Choosing a ½ cup of bran cereal for breakfast is ideal.
• D. Opting for 1 ounce of almonds when hungry midday is recommended.

Correct answer: C

Rationale: The correct answer is C because bran cereal is a high-fiber food that can effectively alleviate constipation by promoting regular bowel movements. Option A, an apple, while a healthy snack, may not provide as much fiber as bran cereal. Option B, sweet potatoes, are nutritious but may not be as high in fiber as bran cereal. Option D, almonds, are a good source of healthy fats and protein but do not provide as much fiber as bran cereal.

3. The nurse is reviewing laboratory results on a client with acute renal failure. Which one of the following should be reported immediately?

• A. Blood urea nitrogen 50 mg/dl
• B. Hemoglobin of 10.3 g/dl
• C. Venous blood pH 7.30
• D. Serum potassium 6 mEq/L

Correct answer: D

Rationale: A serum potassium level of 6 mEq/L indicates hyperkalemia, which can be life-threatening and requires immediate intervention. Hyperkalemia can lead to dangerous cardiac arrhythmias and must be addressed promptly. The other options are not as urgent. A blood urea nitrogen level of 50 mg/dl may indicate kidney dysfunction but does not require immediate intervention. Hemoglobin of 10.3 g/dl may suggest anemia, which needs management but is not an immediate threat. A venous blood pH of 7.30 may indicate acidosis, which is concerning but not as acutely dangerous as hyperkalemia.

4. When administering enteral feeding to a client via a jejunostomy tube, the nurse should administer the formula

• A. Every four to six hours
• B. Continuously
• C. In a bolus
• D. Every hour

Correct answer: B

Rationale: When administering enteral feeding through a jejunostomy tube, the nurse should administer the formula continuously. Continuous feeding is essential for optimal nutrient absorption and to prevent complications. Administering the formula every four to six hours, in a bolus, or every hour may lead to inadequate nutrition, improper absorption, and an increased risk of complications such as aspiration or dumping syndrome, making these choices incorrect.

5. A client is diagnosed with a spontaneous pneumothorax necessitating the insertion of a chest tube. What is the best explanation for the nurse to provide this client?

• A. The tube will drain fluid from your chest.
• B. The tube will remove excess air from your chest.
• C. The tube controls the amount of air that enters your chest.
• D. The tube will seal the hole in your lung.

Correct answer: B

Rationale: The correct answer is B: 'The tube will remove excess air from your chest.' In a spontaneous pneumothorax, air accumulates in the pleural space, causing lung collapse. The chest tube is inserted to remove this excess air, allowing the lung to re-expand. Choices A, C, and D are incorrect because the primary purpose of a chest tube in pneumothorax is to evacuate air, not fluid, control air entry, or seal a lung hole.
