Nursing Elites

1. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.

2. A 65-year-old woman presents with difficulty swallowing, weight loss, and a history of long-standing heartburn. She has been on proton-pump inhibitors for years, but her symptoms have worsened. What is the most likely diagnosis?

• A. Peptic stricture
• B. Esophageal cancer
• C. Achalasia
• D. Esophageal spasm

Correct answer: B

Rationale: The presentation of difficulty swallowing, weight loss, and worsening symptoms despite long-term use of proton-pump inhibitors raises suspicion for esophageal cancer, especially in a patient with a history of chronic heartburn. Esophageal cancer should be considered in this scenario due to the concerning symptoms and lack of improvement despite appropriate medical management.

3. 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.

4. 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.

5. A healthcare provider is providing dietary teaching to a client with cholecystitis. Which type of diet should the healthcare provider recommend?

• A. High-fiber, low-fat diet
• B. Low-fiber, high-protein diet
• C. Low-fat, low-cholesterol diet
• D. High-protein, high-fat diet

Correct answer: C

Rationale: In cholecystitis, a low-fat, low-cholesterol diet is recommended to manage symptoms and reduce inflammation by reducing the workload on the gallbladder. This diet helps prevent gallbladder attacks and complications.
