Nursing Elites

1. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

2. Steven John has type 1 diabetes mellitus and receives insulin. Which laboratory test will the nurse assess?

• A. Potassium
• B. AST (aspartate aminotransferase)
• C. Serum amylase
• D. Sodium

Correct answer: A

Rationale: The correct answer is A: Potassium. Patients with type 1 diabetes receiving insulin are at risk of developing hypokalemia due to insulin's effects on potassium levels. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. Choices B, C, and D are incorrect because AST, serum amylase, and sodium levels are not directly impacted by insulin therapy in type 1 diabetes and are not the primary concern that needs monitoring in this scenario.

3. Which of the following nursing interventions should be taken for a client who complains of nausea and vomits one hour after taking his glyburide (DiaBeta)?

• A. Administer glyburide again
• B. Administer subcutaneous insulin and monitor blood glucose
• C. Monitor blood glucose closely, and look for signs of hypoglycemia
• D. Monitor blood glucose and assess for signs of hyperglycemia

Correct answer: C

Rationale: After a client complains of nausea and vomits one hour after taking glyburide, the priority nursing intervention should be to monitor blood glucose closely and look for signs of hypoglycemia. Vomiting could indicate that the glyburide was not properly absorbed, potentially leading to hypoglycemia. Administering glyburide again (Choice A) could worsen hypoglycemia. Administering subcutaneous insulin (Choice B) is not appropriate without assessing the blood glucose first. Monitoring for signs of hyperglycemia (Choice D) is not the immediate concern in this situation.

4. A client with diabetes experiences Somogyi's effect. To prevent this complication, the nurse should instruct the client to:

• A. Take insulin at 2:00 PM each day
• B. Engage in physical activity daily
• C. Increase the dose of regular insulin
• D. Eat a protein and carbohydrate snack at bedtime

Correct answer: D

Rationale: Somogyi effect, also known as rebound hyperglycemia, occurs as a response to nighttime hypoglycemia. Eating a protein and carbohydrate snack at bedtime can help prevent this by stabilizing blood sugar levels throughout the night. Instructing the client to take insulin at 2:00 PM each day (Choice A) may not directly address the nighttime hypoglycemia concern. Engaging in physical activity daily (Choice B) is generally beneficial for diabetes management but may not specifically prevent Somogyi's effect. Increasing the dose of regular insulin (Choice C) without addressing the nighttime hypoglycemia issue can exacerbate the problem.

5. A patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

• A. 3% sodium chloride
• B. 10% dextrose in water
• C. 0.45% sodium chloride
• D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.
