Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which instruction should the nurse provide?

• A. Use oxygen continuously, even while sleeping.
• B. Adjust the oxygen flow rate to 5 liters per minute if short of breath.
• C. Report any signs of difficulty breathing immediately.
• D. Take off the oxygen while eating or drinking.

Correct answer: A

Rationale: The correct instruction for a client with COPD receiving oxygen therapy is to use oxygen continuously, even while sleeping. This is important to ensure adequate oxygenation and optimal respiratory function for clients with COPD. Continuous oxygen therapy helps maintain oxygen levels during sleep, which is crucial for individuals with COPD who may experience nighttime hypoxemia. Therefore, advising the client to use oxygen continuously, even during sleep, is essential in managing COPD and preventing complications associated with oxygen deprivation.

2. The healthcare provider formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely cause for this nursing diagnosis?

• A. Pain during coughing.
• B. Diminished cough effort.
• C. Thick, dry secretions.
• D. Excessive inflammation.

Correct answer: B

Rationale: Clients with myasthenia gravis commonly experience muscle weakness, including in the muscles used for coughing. This diminished cough effort can lead to ineffective airway clearance, increasing the risk of respiratory complications. Therefore, the most likely cause for the nursing diagnosis 'High risk for ineffective airway clearance' in a client with myasthenia gravis is the diminished cough effort due to muscle weakness.

3. A 45-year-old man with a history of chronic heartburn presents with progressive difficulty swallowing solids and liquids. He has lost 10 pounds in the past two months. What is the most likely diagnosis?

• A. Esophageal stricture
• B. Esophageal cancer
• C. Achalasia
• D. Peptic ulcer disease

Correct answer: B

Rationale: In this scenario, the patient's presentation of progressive dysphagia to both solids and liquids, along with significant weight loss, is concerning for esophageal cancer. The history of chronic heartburn further raises suspicion as chronic gastroesophageal reflux disease is a risk factor for the development of esophageal adenocarcinoma. Esophageal stricture could cause dysphagia but is less likely to be associated with significant weight loss. Achalasia typically presents with dysphagia to solids more than liquids and does not commonly cause weight loss. Peptic ulcer disease is less likely to lead to progressive dysphagia and significant weight loss compared to esophageal cancer.

4. A client with type 1 diabetes mellitus is admitted with hyperglycemia. Which laboratory result requires the most immediate intervention?

• A. Serum glucose of 350 mg/dL.
• B. Serum potassium of 2.8 mEq/L.
• C. Serum sodium of 136 mEq/L.
• D. Serum bicarbonate of 20 mEq/L.

Correct answer: B

Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.

5. A 46-year-old man with a history of cirrhosis is brought in by his wife because he has been acting strangely. On examination, he is disoriented, ataxic, and has slurred speech. He is also hyperreflexic. His white blood cell count is normal. His hematocrit is 34%. Coagulation times are elevated. His ammonia level is normal. Which of the following statements regarding his management is correct?

• A. He should be treated with a low-protein diet and lactulose
• B. Lorazepam is not the drug of choice to control his behavior
• C. He should not be placed on gentamicin prophylactically to prevent the development of peritonitis
• D. If the patient complains of pain, acetaminophen should be avoided and nonsteroidal anti-inflammatory agents should be used

Correct answer: A

Rationale: This patient presents with symptoms consistent with hepatic encephalopathy. Despite having a normal ammonia level, he should be treated with lactulose and a low-protein diet as recommended for stage 2 hepatic encephalopathy. The normal ammonia level does not exclude the diagnosis, as it lacks sensitivity and specificity. Medications like lorazepam, gentamicin, and NSAIDs should be avoided due to their potential adverse effects in patients with liver disease. Acetaminophen should also be avoided in such patients.
