Nursing Elites

1. 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.

2. A nurse is comparing the rate of medication errors on the medical unit to the rate from a medical unit in a magnet hospital. Which of the following quality improvement methods is the nurse using?

• A. Structure audit
• B. Benchmarking
• C. Risk benefit analysis
• D. Root cause analysis

Correct answer: B

Rationale: The correct answer is B: Benchmarking. Benchmarking involves comparing performance metrics with those from other units or institutions, which is exactly what the nurse is doing by comparing the rate of medication errors on their medical unit to the rate from a medical unit in a magnet hospital. Choice A, Structure audit, is not relevant to this scenario as it focuses on assessing the physical, organizational, or procedural structures in a healthcare setting. Choice C, Risk benefit analysis, involves weighing the potential risks and benefits of a particular course of action, not comparing performance metrics. Choice D, Root cause analysis, is a method used to identify the underlying causes of problems or adverse events, not to compare performance metrics between units.

3. What percentage of term newborns have a congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion?

• A. 2% to 4%
• B. 10% to 20%
• C. 5% to 10%
• D. 7% to 9%

Correct answer: A

Rationale: The correct answer is A: 2% to 4%. According to research, 2% to 4% of term newborns have congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion. Choices B, C, and D provide percentages that are higher than the actual prevalence of congenital heart disease in newborns caused by environmental factors, making them incorrect.

4. Insulin forces which of the following electrolytes out of the plasma and into the cells?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

5. Rotating injection sites when administering insulin prevents which of the following complications?

• A. Insulin edema
• B. Insulin lipodystrophy
• C. Insulin resistance
• D. Systemic allergic reactions

Correct answer: B

Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.
