Nursing Elites

1. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain a sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw the catheter in a circular motion

Correct answer: A

Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.

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. A client with a history of pancreatitis should avoid which of the following food choices?

• A. Noodles
• B. Vegetable soup
• C. Baked fish
• D. Cheddar cheese

Correct answer: D

Rationale: Clients with pancreatitis should avoid high-fat foods like cheddar cheese as they can exacerbate symptoms. Noodles, vegetable soup, and baked fish are generally lower in fat and may be better tolerated by clients with pancreatitis.

4. Which of these clients with associated lab reports is a priority for the nurse to report to the public health department within the next 24 hours?

• A. An infant with a positive stool culture for Shigella
• B. An elderly factory worker with a positive lab report for acid-fast bacillus smear
• C. A young adult commercial pilot with a positive histopathological examination for Pneumocystis carinii from an induced sputum
• D. A middle-aged nurse with a history of varicella-zoster virus and crops of vesicles on an erythematous base appearing on the skin

Correct answer: B

Rationale: The correct answer is B because a positive acid-fast bacillus smear in an elderly factory worker suggests tuberculosis, a serious communicable disease that must be reported promptly to the public health department to prevent its spread. Choice A is incorrect as Shigella is an important pathogen, but it does not require immediate public health reporting. Choice C is incorrect because Pneumocystis carinii is an opportunistic pathogen and does not require urgent public health reporting. Choice D is incorrect as varicella-zoster virus causes chickenpox and shingles, both of which are not reportable diseases to the public health department.

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.
