Nursing Elites

1. A 55-year-old man presents with jaundice, pruritus, and dark urine. Laboratory tests reveal elevated bilirubin and alkaline phosphatase. Imaging shows dilated intrahepatic bile ducts and a normal common bile duct. What is the most likely diagnosis?

• A. Primary biliary cirrhosis
• B. Primary sclerosing cholangitis
• C. Gallstones
• D. Pancreatic cancer

Correct answer: A

Rationale: The clinical presentation of jaundice, pruritus, dark urine, elevated bilirubin and alkaline phosphatase, along with imaging findings of dilated intrahepatic bile ducts and a normal common bile duct, are characteristic of primary biliary cirrhosis. Primary biliary cirrhosis is an autoimmune liver disease that leads to destruction of intrahepatic bile ducts, causing cholestasis and liver damage. This condition typically presents in middle-aged women but can also affect men, as seen in this case.

2. A patient with chronic pain is prescribed a fentanyl patch. What is the most important instruction for the nurse to provide?

• A. Apply the patch to a different site each time.
• B. Change the patch every 72 hours.
• C. Avoid using additional heating pads over the patch.
• D. Remove the patch before showering.

Correct answer: B

Rationale: The most important instruction for the nurse to provide to a patient prescribed a fentanyl patch is to change the patch every 72 hours. This ensures consistent pain control and prevents complications. It is crucial to rotate the application sites to prevent skin irritation or reactions. Using additional heating pads over the patch should be avoided as it can increase the absorption of the medication, leading to overdose or adverse effects. Removing the patch before showering is not necessary as long as the patch is securely in place.

3. A 45-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. Imaging shows a normal common bile duct but dilated intrahepatic bile ducts. What is the most likely diagnosis?

• A. Primary biliary cirrhosis
• B. Primary sclerosing cholangitis
• C. Gallstones
• D. Pancreatic cancer

Correct answer: A

Rationale: Based on the symptoms of fatigue, pruritus, and jaundice, along with elevated bilirubin and alkaline phosphatase levels, and imaging findings of a normal common bile duct but dilated intrahepatic bile ducts, the most likely diagnosis is primary biliary cirrhosis. Primary sclerosing cholangitis presents with different imaging findings, often showing strictures and beading of the bile ducts. Gallstones typically cause obstruction in the biliary system, leading to different symptoms and imaging findings. Pancreatic cancer would present with different clinical features and imaging characteristics.

4. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.

5. A patient with an anxiety disorder is prescribed alprazolam. What is the primary action of this medication?

• A. Increase energy levels
• B. Induce sedation
• C. Elevate mood
• D. Reduce anxiety

Correct answer: D

Rationale: Alprazolam is a benzodiazepine that primarily works by reducing anxiety. It achieves this by enhancing the inhibitory effects of the neurotransmitter GABA in the brain, which leads to a calming effect on the individual. Therefore, the primary action of alprazolam is to decrease anxiety levels rather than increase energy, induce sedation, or elevate mood.
