1. What is one benefit of using a large sample size in an experiment?

Correct answer: A

Rationale: Corrected Rationale: Using a large sample size reduces the likelihood of chance variation affecting the results, providing more reliable data. Choice B is incorrect because the placebo effect is related to participants' beliefs, not sample size. Choice C is incorrect as double-blind refers to a method of reducing bias, not directly related to sample size. Choice D is incorrect because the similarity between the control and experimental groups is not solely dependent on sample size.

2. What is a primary concern for a child with a new diagnosis of diabetes mellitus?

Correct answer: B

Rationale: The correct answer is B: Risk of hyperglycemia. When a child is newly diagnosed with diabetes mellitus, one of the primary concerns is the risk of hyperglycemia, which refers to high blood glucose levels. Hyperglycemia can lead to various complications if not managed properly, making it crucial to stabilize blood glucose levels. Choices A, C, and D are incorrect because increased growth rate, risk of dehydration, and improved appetite are not primary concerns specifically associated with a new diagnosis of diabetes mellitus.

3. What should the nurse anticipate as challenging in caring for a child with acute glomerulonephritis?

Correct answer: C

Rationale: The correct answer is C: Bed rest. Implementing bed rest can be challenging, especially in active children, but it's necessary to manage the symptoms of acute glomerulonephritis. Forced fluids (choice A) may be required to maintain hydration but are not typically challenging. Increased feedings (choice B) and frequent position changes (choice D) are not primary interventions in the care of a child with acute glomerulonephritis.

4. Which medication is typically used for long-term control of asthma?

Correct answer: B

Rationale: The correct answer is B, Theophylline. Theophylline is commonly used for long-term control of asthma by relaxing the muscles around the airways to keep them open, making breathing easier. Albuterol (choice A) is a short-acting bronchodilator for quick relief of asthma symptoms, not for long-term control. Ipratropium (choice C) is another short-acting bronchodilator that helps open the airways but is not typically used for long-term control. Prednisone (choice D) is a corticosteroid usually used for short periods to control asthma exacerbations or flare-ups, not as a long-term control medication.

5. Which statement is true of minerals in their role as nutrients?

Correct answer: C

Rationale: The correct statement is that some minerals become dissolved in body fluids, making them available for absorption and utilization by the body. Minerals are not organic compounds, so choice A is incorrect. Choice B is incorrect because minerals do not provide energy like macronutrients such as carbohydrates and fats. Choice D is incorrect because minerals are elements and cannot be destroyed by cooking; however, their availability and absorption may be affected by cooking methods.
