Nursing Elites

1. A client who is acutely ill has vigilant oral care included in their plan of care. What factor increases this client's risk for dental caries?

• A. Hormonal changes induced by the stress response leading to an acidic oral environment
• B. Systemic infections commonly affecting the teeth
• C. Intravenous hydration lacking fluoride
• D. Inadequate nutrition and reduced saliva production contributing to cavities

Correct answer: D

Rationale: Inadequate nutrition and decreased saliva production can lead to a conducive environment for the development of dental caries. Without proper nutrition and sufficient saliva, the protective mechanisms against cavities are compromised, making the individual more susceptible to tooth decay.

2. A client with chronic renal failure is prescribed erythropoietin (Epogen). Which outcome indicates that the medication is effective?

• A. Increased urine output.
• B. Improved hemoglobin levels.
• C. Decreased blood pressure.
• D. Stable potassium levels.

Correct answer: B

Rationale: The correct answer is B: Improved hemoglobin levels. Erythropoietin (Epogen) stimulates red blood cell production, leading to an increase in hemoglobin levels in clients with chronic renal failure. Monitoring hemoglobin levels is crucial to assess the effectiveness of erythropoietin therapy in managing anemia associated with chronic renal failure. While increased urine output, decreased blood pressure, and stable potassium levels are important parameters to monitor in clients with renal failure, they are not direct indicators of the effectiveness of erythropoietin therapy.

3. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

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

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

4. What is the most likely diagnosis in a 30-year-old woman with right upper quadrant pain, fever, and jaundice, along with elevated white blood cell count and bilirubin levels?

• A. Acute hepatitis
• B. Acute cholecystitis
• C. Acute cholangitis
• D. Pancreatic cancer

Correct answer: C

Rationale: The combination of right upper quadrant pain, fever, jaundice, elevated white blood cell count, and bilirubin levels is classic for acute cholangitis, which is an infection of the bile ducts. Acute hepatitis typically presents with other liver function abnormalities, while acute cholecystitis is characterized by gallbladder inflammation. Pancreatic cancer would not typically present with these specific symptoms and lab findings.

5. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.
