Nursing Elites

1. 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.

2. A client in acute renal failure has a serum potassium level of 6.3 mEq/L. What intervention can the nurse expect the healthcare provider to prescribe?

• A. Nitrofurantoin (Macrodantin) orally.
• B. Erythropoietin (Epogen) intravenously.
• C. Kayexalate retention enema.
• D. Azathioprine (Imuran) orally.

Correct answer: C

Rationale: In acute renal failure with high serum potassium levels, the healthcare provider is likely to prescribe a Kayexalate retention enema. Kayexalate is a medication used to lower elevated potassium levels by promoting potassium excretion through the gastrointestinal tract, thus aiding in the management of hyperkalemia in clients with renal failure.

3. The client has a nasogastric (NG) tube and is receiving enteral feedings. What intervention should the nurse implement to prevent complications associated with the NG tube?

• A. Flush the NG tube with water before and after feedings.
• B. Check gastric residual volume every 6 hours.
• C. Keep the head of the bed elevated at 30 degrees.
• D. Replace the NG tube every 24 hours.

Correct answer: C

Rationale: Keeping the head of the bed elevated at 30 degrees is crucial in preventing aspiration, a common complication associated with nasogastric (NG) tubes and enteral feedings. This position helps reduce the risk of reflux and aspiration of gastric contents into the lungs, promoting client safety and preventing respiratory complications. Flushing the NG tube with water before and after feedings (Choice A) is not the primary intervention to prevent complications. Checking gastric residual volume every 6 hours (Choice B) is important but not directly related to preventing complications associated with the NG tube. Replacing the NG tube every 24 hours (Choice D) is not a standard practice and is not necessary to prevent complications if the tube is functioning properly.

4. A 28-year-old woman at 34 weeks of gestation presents with elevated liver enzymes and pruritus. Labs reveal total bilirubin to be 4.2 mg/dL, AST 480 U/L, ALT 640 U/L, and alkaline phosphatase 232 U/L. Viral hepatitis serologies and ANA are negative. On physical examination, she is jaundiced, but has a normal blood pressure, no edema, and a soft abdomen. The fetus is in no distress. Which of the following is true?

• A. The baby should be delivered immediately
• B. Symptoms will resolve promptly after delivery
• C. There is little risk of recurrence with subsequent pregnancies
• D. The mother should be screened for long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency

Correct answer: B

Rationale: The patient's presentation is consistent with intrahepatic cholestasis of pregnancy (ICP), a condition characterized by elevated liver enzymes, pruritus, and jaundice in the absence of other liver disease causes. ICP typically resolves promptly after delivery. Immediate delivery is indicated only for fetal distress, not maternal symptoms. ICP does have a significant risk of recurrence in subsequent pregnancies. Treatment options for ICP include cholestyramine and ursodeoxycholic acid. Screening for long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is not indicated in this context as it is associated with acute fatty liver of pregnancy and HELLP syndrome, not ICP.

5. A client who is 2 days postoperative reports severe pain and swelling in the right leg. The nurse notes that the leg is warm and red. What is the nurse's priority action?

• A. Apply a warm compress to the affected leg.
• B. Elevate the leg on pillows.
• C. Measure the circumference of the leg.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The nurse's priority action in this situation is to notify the healthcare provider immediately. These symptoms, including severe pain, swelling, warmth, and redness in the leg, are indicative of deep vein thrombosis (DVT), a potentially serious condition. Prompt notification of the healthcare provider is crucial to initiate appropriate diagnostic tests and interventions to prevent complications associated with DVT. Applying a warm compress (Choice A) could worsen the condition by increasing blood flow. Elevating the leg (Choice B) might be contraindicated in DVT as it can dislodge a clot. Measuring the circumference of the leg (Choice C) is not the priority at this time compared to promptly involving the healthcare provider.
