Nursing Elites

1. 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.

2. 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.

3. A patient with diabetes insipidus is prescribed desmopressin. What is the primary purpose of this medication?

• A. Increase urine output
• B. Reduce blood sugar levels
• C. Decrease urine output
• D. Lower blood pressure

Correct answer: C

Rationale: Desmopressin is prescribed to decrease urine output in patients with diabetes insipidus. It works by increasing water reabsorption in the kidneys, helping to control fluid balance in the body.

4. 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.

5. A client with portal hypertension who has developed ascites is scheduled for a paracentesis. What pre-procedure nursing intervention is essential?

• A. Encourage the client to empty the bladder
• B. Administer a laxative to clear the bowels
• C. Restrict the client's fluid intake
• D. Place the client in a supine position

Correct answer: A

Rationale: Emptying the bladder before a paracentesis is essential to prevent bladder injury during the procedure. A full bladder may be in the path of the needle insertion, increasing the risk of bladder puncture. Encouraging the client to empty the bladder ensures their safety and reduces the likelihood of complications.
