Nursing Elites

1. What action should the nurse take for a patient admitted with diabetic ketoacidosis exhibiting rapid, deep respirations?

• A. Administer the prescribed PRN lorazepam (Ativan).
• B. Start the prescribed PRN oxygen at 2 to 4 L/min.
• C. Administer the prescribed normal saline bolus and insulin.
• D. Encourage the patient to practice guided imagery for relaxation.

Correct answer: C

Rationale: The correct action for a patient with diabetic ketoacidosis and rapid, deep (Kussmaul) respirations is to administer a normal saline bolus and insulin. The rapid, deep respirations indicate a metabolic acidosis, which requires correction with a saline bolus to prevent hypovolemia and insulin to facilitate glucose re-entry into cells. Oxygen therapy is not necessary since the increased respiratory rate is compensatory and not due to hypoxemia. Encouraging relaxation techniques or administering lorazepam are inappropriate as they can worsen the acidosis by suppressing the compensatory respiratory effort.

2. A 28-year-old woman presents with abdominal pain, diarrhea, and weight loss. She has a history of recurrent mouth ulcers and a perianal fistula. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Crohn's disease
• D. Diverticulitis

Correct answer: C

Rationale: The combination of symptoms including recurrent mouth ulcers, perianal fistula, abdominal pain, diarrhea, and weight loss is characteristic of Crohn's disease. These extra-intestinal manifestations, along with the gastrointestinal symptoms, point towards Crohn's disease rather than ulcerative colitis, irritable bowel syndrome, or diverticulitis.

3. A client with chronic kidney disease (CKD) is experiencing hyperkalemia. Which intervention should the nurse implement to address this condition?

• A. Administer calcium gluconate.
• B. Encourage a diet high in potassium.
• C. Provide potassium supplements.
• D. Restrict sodium intake.

Correct answer: A

Rationale: Administering calcium gluconate is the appropriate intervention for a client with hyperkalemia. Calcium gluconate helps stabilize the heart by counteracting the effects of high potassium levels and reducing the risk of cardiac complications in individuals with hyperkalemia. Choices B, C, and D are incorrect. Encouraging a diet high in potassium or providing potassium supplements would exacerbate hyperkalemia. Restricting sodium intake is not directly related to addressing hyperkalemia.

4. 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.

5. 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.
