1. What is the most effective nursing intervention to prevent atelectasis from developing in a postoperative client?
- A. Maintain adequate hydration
- B. Assist the client to turn, deep breathe, and cough
- C. Ambulate the client within 12 hours
- D. Splint the incision
Correct answer: B
Rationale: The correct answer is to assist the client to turn, deep breathe, and cough. This intervention helps to expand the lungs and prevent atelectasis in postoperative clients. Maintaining adequate hydration is important for overall health but is not the most effective intervention for preventing atelectasis. Ambulating the client within 12 hours is beneficial for preventing complications after surgery, but it may not be as directly effective in preventing atelectasis as turning, deep breathing, and coughing. Splinting the incision is important for postoperative care, but it does not specifically address the prevention of atelectasis.
2. 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.
3. The nurse is caring for a client who requires a mechanical ventilator for breathing. The high-pressure alarm goes off on the ventilator. What is the first action the nurse should perform?
- A. Disconnect the client from the ventilator and use a manual resuscitation bag
- B. Perform a quick assessment of the client's condition
- C. Call the respiratory therapist for help
- D. Press the alarm reset button on the ventilator
Correct answer: B
Rationale: When the high-pressure alarm on a ventilator goes off, the nurse's initial action should be to perform a quick assessment of the client's condition. This assessment helps in promptly identifying the cause of the alarm, such as mucus plugging, kinking of the tubing, or other issues. By assessing the client first, the nurse can determine the appropriate intervention needed to address the alarm. Choices A and D are incorrect because disconnecting the client from the ventilator or pressing the alarm reset button should not be the initial actions without assessing the client's condition. While calling the respiratory therapist for help could be beneficial, assessing the client's condition should be the nurse's priority to address the immediate concern.
4. The client is being taught about precautions with Coumadin therapy. Which over-the-counter medication should the client be instructed to avoid?
- A. Non-steroidal anti-inflammatory drugs
- B. Cough medicines with guaifenesin
- C. Histamine blockers
- D. Laxatives containing magnesium salts
Correct answer: A
Rationale: The correct answer is A: Non-steroidal anti-inflammatory drugs (NSAIDs). When a client is on Coumadin therapy, NSAIDs should be avoided because they can increase the risk of bleeding due to their antiplatelet effects. Choices B, C, and D are incorrect. Cough medicines with guaifenesin, histamine blockers, and laxatives containing magnesium salts do not have a significant interaction with Coumadin therapy that would necessitate avoidance.
5. 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.
