Nursing Elites

1. A client with a history of chronic alcohol use is admitted with confusion and an unsteady gait. Which deficiency should the nurse suspect?

• A. Thiamine (Vitamin B1)
• B. Cyanocobalamin (Vitamin B12)
• C. Folic acid
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Thiamine (Vitamin B1). Chronic alcohol use can lead to thiamine deficiency, which can result in neurological symptoms such as confusion and an unsteady gait. Thiamine is essential for proper brain function and nerve conduction, and its deficiency is common in individuals with alcohol use disorder. Cyanocobalamin (Vitamin B12) deficiency can also present with neurological symptoms, but in this case, the patient's history of chronic alcohol use points more towards thiamine deficiency. Folic acid deficiency typically presents with symptoms like fatigue and megaloblastic anemia. Vitamin D deficiency is associated with bone health issues rather than neurological symptoms.

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 client receiving total parenteral nutrition (TPN) through a central line suddenly develops dyspnea, chest pain, and a drop in blood pressure. What should the nurse do first?

• A. Stop the TPN infusion.
• B. Notify the healthcare provider.
• C. Place the client in Trendelenburg position.
• D. Administer oxygen at 2 liters/minute.

Correct answer: C

Rationale: Placing the client in Trendelenburg position should be the initial action as it can help manage a suspected air embolism, a potential complication of TPN administration. This position helps trap air in the apex of the atrium, reducing the risk of air reaching the pulmonary circulation and causing further harm. Once the client is in a safe position, further actions such as stopping the TPN infusion, notifying the healthcare provider, and administering oxygen can be taken as appropriate.

4. A patient with bipolar disorder is prescribed lithium. What dietary advice should the nurse provide?

• A. Increase intake of caffeine.
• B. Maintain a consistent salt intake.
• C. Avoid dairy products.
• D. Increase intake of green leafy vegetables.

Correct answer: B

Rationale: The correct answer is B: Maintain a consistent salt intake. Patients prescribed lithium should maintain a consistent salt intake to help stabilize lithium levels. Fluctuations in salt intake can affect the levels of lithium in the body, potentially leading to toxicity or reduced effectiveness of the medication. It is important for patients to be consistent with their salt intake and to avoid sudden increases or decreases. Choices A, C, and D are incorrect. Increasing intake of caffeine is not recommended as it can interfere with the effects of lithium. Avoiding dairy products is not necessary unless there are specific intolerances or interactions with other medications. While green leafy vegetables are generally healthy, there is no specific recommendation to increase their intake in relation to lithium therapy.

5. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.
