Nursing Elites

1. A 62-year-old male client with a history of coronary artery disease complains that his heart is 'racing' and he often feels dizzy. His blood pressure is 110/60, and he uses portable oxygen at 2 liters per nasal cannula. Based on the rhythm shown, which prescription should the nurse administer?

• A. Give magnesium via secondary infusion.
• B. Initiate IV heparin solution as per protocol.
• C. Administer IV adenosine (Adenocard).
• D. Prepare for synchronized cardioversion.

Correct answer: C

Rationale: Administering IV adenosine is the appropriate intervention for a client with symptomatic tachycardia to restore normal sinus rhythm. Adenosine is a medication used to treat supraventricular tachycardia (SVT) by interrupting the reentry pathways through the AV node and restoring normal sinus rhythm. It is a rapid-acting medication given as a rapid IV push followed by a saline flush. The dose is typically administered in a healthcare setting where cardiac monitoring is available due to its potential to cause transient asystole.

2. For a patient with asthma, what is the primary purpose of prescribing montelukast?

• A. Relieve acute bronchospasm
• B. Prevent asthma attacks
• C. Thin respiratory secretions
• D. Suppress cough

Correct answer: B

Rationale: Montelukast, a leukotriene receptor antagonist, is primarily prescribed to prevent asthma attacks. It works by reducing inflammation and bronchoconstriction in the airways, thereby helping to control asthma symptoms and prevent exacerbations.

3. A client with Addison's disease is being treated with fludrocortisone (Florinef). Which electrolyte imbalance should the nurse monitor for?

• A. Hyperkalemia.
• B. Hyponatremia.
• C. Hypernatremia.
• D. Hypocalcemia.

Correct answer: C

Rationale: Fludrocortisone, such as Florinef, is a mineralocorticoid that promotes sodium retention and potassium excretion, which can lead to hypernatremia. Therefore, the nurse should closely monitor for hypernatremia when a client with Addison's disease is being treated with fludrocortisone. Hyperkalemia (Choice A) is incorrect because fludrocortisone promotes potassium excretion, leading to hypokalemia rather than hyperkalemia. Hyponatremia (Choice B) is incorrect as fludrocortisone promotes sodium retention. Hypocalcemia (Choice D) is unrelated to the action of fludrocortisone.

4. What is the primary action of digoxin when prescribed to a patient with heart failure?

• A. Increase heart rate
• B. Decrease cardiac output
• C. Strengthen cardiac contractions
• D. Lower blood pressure

Correct answer: C

Rationale: Digoxin, when prescribed to a patient with heart failure, primarily acts by strengthening cardiac contractions. This leads to an improvement in cardiac output, making it an essential medication in managing heart failure. By enhancing the force of contractions, digoxin helps the heart pump more effectively and efficiently, leading to better circulation and symptom control in patients with compromised cardiac function.

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.
