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 client with a new diagnosis of diabetes mellitus is learning to self-administer insulin. Which instruction should the nurse include?

• A. Store the insulin in the freezer.
• B. Administer the insulin at the same site each time.
• C. Rotate injection sites within the same region.
• D. Shake the vial vigorously before drawing up the insulin.

Correct answer: C

Rationale: The correct instruction for a client learning to self-administer insulin is to rotate injection sites within the same region. This practice helps prevent lipodystrophy, which is a condition characterized by fat tissue changes due to repeated injections in the same spot, and also ensures consistent absorption of insulin throughout the body. Storing insulin in the freezer is incorrect as it can lead to denaturation of the insulin. Administering the insulin at the same site each time can cause lipodystrophy and inconsistent absorption. Shaking the vial vigorously before drawing up the insulin is also incorrect as it can lead to insulin degradation.

3. During an assessment, a healthcare professional suspects a client has cholecystitis. What is a common symptom of this condition?

• A. Right upper quadrant pain
• B. Left lower quadrant pain
• C. Generalized abdominal pain
• D. Epigastric pain

Correct answer: A

Rationale: Right upper quadrant pain is a hallmark symptom of cholecystitis, indicating inflammation of the gallbladder. The gallbladder is typically located in the right upper quadrant of the abdomen, so pain in this area is characteristic of cholecystitis. This pain may be sharp or cramp-like and can be accompanied by other symptoms such as nausea, vomiting, and fever. Left lower quadrant pain (choice B) is more commonly associated with diverticulitis, generalized abdominal pain (choice C) can be seen in various conditions, and epigastric pain (choice D) is typically related to issues in the upper central part of the abdomen, such as gastritis or peptic ulcers, rather than cholecystitis.

4. A client is on a mechanical ventilator. Which client response indicates that the neuromuscular blocker tubocurarine chloride (Tubarine) is effective?

• A. The client's extremities are paralyzed.
• B. The peripheral nerve stimulator causes twitching.
• C. The client clenches fist upon command.
• D. The client's Glasgow Coma Scale score is 14.

Correct answer: A

Rationale: The correct answer is A. Tubocurarine chloride is a neuromuscular blocker that works by causing paralysis of skeletal muscles. Therefore, if the client's extremities are paralyzed, it indicates that the medication is effective in achieving the desired muscle relaxation necessary for mechanical ventilation. Choices B and C are incorrect as they suggest muscle activity, which would not be expected with the administration of a neuromuscular blocker. Choice D is unrelated to the effectiveness of tubocurarine chloride.

5. 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.
