Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which intervention should the nurse implement to ensure the client's safety?

• A. Increase the oxygen flow rate to 6 liters/minute if the client is short of breath.
• B. Instruct the client to breathe deeply and cough frequently.
• C. Use a nasal cannula to deliver oxygen at a low flow rate.
• D. Encourage the client to remove the oxygen when eating or drinking.

Correct answer: C

Rationale: Using a nasal cannula to deliver oxygen at a low flow rate is the appropriate intervention for clients with COPD receiving oxygen therapy. High flow rates can lead to respiratory depression in COPD patients. This intervention helps maintain a safe and controlled oxygen delivery to prevent potential complications associated with high oxygen flow rates.

2. A client with a history of myocardial infarction (MI) is prescribed atorvastatin (Lipitor). Which outcome indicates that the medication is effective?

• A. Increased blood pressure.
• B. Lowered cholesterol levels.
• C. Decreased heart rate.
• D. Improved liver function.

Correct answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.

3. A 50-year-old man presents with progressive jaundice, dark urine, and pruritus. Imaging reveals a mass in the head of the pancreas. What is the most likely diagnosis?

• A. Pancreatic cancer
• B. Chronic pancreatitis
• C. Gallstones
• D. Primary sclerosing cholangitis

Correct answer: A

Rationale: The presentation of progressive jaundice, dark urine, and pruritus along with a pancreatic mass, particularly in the head of the pancreas, strongly suggests pancreatic cancer as the most likely diagnosis. These symptoms are classic for obstructive jaundice caused by a mass in the head of the pancreas, making pancreatic cancer the most fitting choice.

4. A 60-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Hepatitis C
• B. Primary biliary cirrhosis
• C. Hemochromatosis
• D. Wilson's disease

Correct answer: B

Rationale: The symptoms of fatigue, pruritus, jaundice, and elevated bilirubin and alkaline phosphatase levels are classic features of primary biliary cirrhosis, an autoimmune liver disease. Hepatitis C typically presents with different symptoms and findings, such as specific viral markers. Hemochromatosis and Wilson's disease involve iron overload and copper accumulation, respectively, leading to distinct clinical and laboratory findings, which do not match the presentation described in this case.

5. The nurse is administering sevelamer (RenaGel) during lunch to a client with end-stage renal disease (ESRD). The client asks the nurse to bring the medication later. The nurse should describe which action of RenaGel as an explanation for taking it with meals?

• A. Prevents indigestion associated with the ingestion of spicy foods.
• B. Binds with phosphorus in foods and prevents absorption.
• C. Promotes stomach emptying and prevents gastric reflux.
• D. Buffers hydrochloric acid and prevents gastric erosion.

Correct answer: B

Rationale: Sevelamer (RenaGel) binds with phosphorus in foods to prevent its absorption, which is why it should be taken with meals. By taking RenaGel with meals, it can effectively bind with phosphorus from food, reducing the amount of phosphorus absorbed by the body, thus helping to manage hyperphosphatemia in clients with ESRD. Choices A, C, and D are incorrect because RenaGel's primary action is to bind with phosphorus in foods, not related to preventing indigestion, promoting stomach emptying, or buffering hydrochloric acid.
