Nursing Elites

1. A patient with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). What is the priority nursing action?

• A. Administer regular insulin intravenously.
• B. Give oral hypoglycemic agents.
• C. Administer sodium bicarbonate.
• D. Provide a high-calorie diet.

Correct answer: A

Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Administering oral hypoglycemic agents is not appropriate in the acute setting of DKA as they may not work quickly enough compared to intravenous insulin. While sodium bicarbonate may be used to correct acidosis, insulin administration is the priority to address both hyperglycemia and acidosis simultaneously. Providing a high-calorie diet is not suitable initially in DKA management; the main focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.

2. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

3. In acute pancreatitis, a client experiencing severe abdominal pain should have which enzyme level closely monitored?

• A. Serum amylase.
• B. Serum sodium.
• C. Serum calcium.
• D. Serum potassium.

Correct answer: A

Rationale: In acute pancreatitis, serum amylase levels should be closely monitored. Elevated serum amylase levels are a key diagnostic marker for acute pancreatitis, aiding in the assessment and management of the patient's condition. Monitoring serum sodium, calcium, or potassium levels is not typically associated with acute pancreatitis and would not provide relevant information for this specific condition.

4. 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.

5. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.
