1. 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.
2. What is the primary goal of public health?
- A. To focus on individual patient care
- B. To improve the health of populations
- C. To reduce healthcare costs
- D. To increase hospital admissions
Correct answer: B
Rationale: The primary goal of public health is to improve the health of populations by focusing on prevention, health promotion, and addressing the social determinants of health. Choice A is incorrect because public health looks at health from a population perspective rather than focusing on individual patient care. Choice C, while a potential benefit, is not the primary goal of public health. Choice D is incorrect as increasing hospital admissions is not a goal of public health; in fact, public health aims to prevent unnecessary hospitalizations through preventive measures.
3. Which type of practice is most similar to research-based practice?
- A. Best practices
- B. Evidence-based practice
- C. Benchmark practices
- D. Standard-based practice
Correct answer: B
Rationale: The correct answer is B: Evidence-based practice. Evidence-based practice relies on research to guide clinical decisions, mirroring the approach of research-based practice. Choice A, Best practices, refers to established methods or techniques that are widely accepted as superior. Choice C, Benchmark practices, typically involves setting standards or goals for performance comparison. Choice D, Standard-based practice, usually pertains to adhering to established norms or guidelines.
4. Dr. Shrunk orders intravenous (IV) insulin for Rita, a client with a blood sugar of 563. Nurse AJ administers insulin lispro (Humalog) intravenously (IV). What does the best evaluation of the nurse reveal? Select one that does not apply.
- A. The nurse could have given the insulin subcutaneously.
- B. The nurse did not have to contact the physician.
- C. The nurse should have used regular insulin (Humulin R).
- D. The nurse used the correct insulin.
Correct answer: C
Rationale: The best evaluation of the nurse reveals that she should have used regular insulin (Humulin R) for IV administration. Regular insulin is the only insulin approved for intravenous administration due to its pharmacokinetic properties. Insulin lispro (Humalog) is not suitable for IV use. Choice A is incorrect because giving insulin intravenously is necessary in this case of high blood sugar. Choice B is incorrect because administering a different insulin without consulting the physician is not appropriate. Choice D is incorrect because the nurse used the incorrect insulin, which could pose risks to the client's health.
5. 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.
