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. Which of these clients, all in the terminal stage of cancer, is least appropriate to suggest the use of patient-controlled analgesia (PCA) with a pump?

• A. A young adult with a history of Down syndrome
• B. A teenager who reads at a 4th-grade level
• C. An elderly client with numerous arthritic nodules on the hands
• D. A preschooler with intermittent alertness

Correct answer: D

Rationale: The correct answer is D, a preschooler with intermittent alertness. This client may not have the cognitive ability to effectively use a PCA pump due to their age and alertness level. They may not understand how to self-administer the analgesia. Choices A, B, and C are more appropriate candidates for PCA as they are likely to have better comprehension and ability to operate the PCA pump compared to a preschooler with intermittent alertness.

3. A client has a history of chronic obstructive pulmonary disease (COPD). As the nurse enters the client's room, the oxygen is running at 6 liters per minute, the client's color is flushed, and his respirations are 8 per minute. What should the nurse do first?

• A. Obtain a 12-lead EKG
• B. Place the client in high Fowler's position
• C. Lower the oxygen rate
• D. Take baseline vital signs

Correct answer: C

Rationale: In a client with COPD, it is crucial to prevent carbon dioxide retention by avoiding high oxygen levels. As the client's oxygen is running at 6 liters per minute and he is showing signs of oxygen toxicity, such as flushed color and low respirations, the nurse's priority should be to lower the oxygen rate. This action helps prevent worsening the client's condition. Obtaining an EKG, placing the client in high Fowler's position, or taking baseline vital signs are important assessments but addressing the potential oxygen toxicity takes precedence in this scenario.

4. A client with heart failure has a prescription for digoxin. The nurse is aware that sufficient potassium should be included in the diet because hypokalemia in combination with this medication:

• A. Can predispose to dysrhythmias
• B. May lead to oliguria
• C. May cause irritability and anxiety
• D. Sometimes alters consciousness

Correct answer: A

Rationale: The correct answer is A: Hypokalemia increases the risk of dysrhythmias when taking digoxin, making potassium intake crucial. Digoxin toxicity is more likely in patients with low potassium levels, leading to an increased risk of dysrhythmias. Choices B, C, and D are incorrect because hypokalemia in combination with digoxin is primarily associated with dysrhythmias rather than oliguria, irritability, anxiety, or alteration of consciousness.

5. While providing home care to a client with congestive heart failure, the nurse is asked how long diuretics must be taken. What is the nurse's best response?

• A. As you urinate more, you will need less medication to control fluid.
• B. You will have to take this medication for about a year.
• C. The medication must be continued so the fluid problem is controlled.
• D. Please talk to your health care provider about medications and treatments.

Correct answer: C

Rationale: Diuretics must be continued to control fluid retention, as stopping them can lead to worsening of congestive heart failure.
