1. Why is randomization important in a scientific experiment?

• A. To minimize the impact of confounding variables.
• B. To eliminate bias in the assignment of subjects to groups.
• C. To contribute to the accuracy and validity of the experiment's results.
• D. To prevent systematic differences between groups.

Correct answer: B

Rationale: Randomization is crucial in a scientific experiment to eliminate bias in the assignment of subjects to groups. By randomly assigning subjects, it helps ensure that any differences observed in the outcomes are due to the experimental treatment and not to preexisting differences between groups. Choice A is incorrect because randomization does not guarantee representativeness but rather minimizes the impact of confounding variables. Choice C is not entirely accurate; while randomization can contribute to accuracy and validity, its primary purpose is to reduce bias. Choice D is incorrect as the goal of randomization is not to balance the number of subjects but to prevent systematic differences between groups.

2. How should a healthcare provider address the nutritional needs of a child with chronic kidney disease?

• A. Increase protein intake
• B. Reduce sodium and phosphorus intake
• C. Promote a high-fat diet
• D. Encourage frequent sugary snacks

Correct answer: B

Rationale: Reducing sodium and phosphorus intake is crucial in managing chronic kidney disease in children because it helps prevent complications such as electrolyte imbalances and bone problems. High protein intake can actually be harmful to the kidneys in this condition as it can lead to increased waste production. A high-fat diet is not recommended as it can contribute to heart and blood vessel problems. Encouraging frequent sugary snacks can lead to further complications like obesity and diabetes, which are not beneficial for a child with chronic kidney disease.

3. How should hydration status be assessed in a child with vomiting and diarrhea?

• A. Check skin turgor and mucous membranes
• B. Measure blood glucose levels
• C. Assess heart rate and blood pressure
• D. Evaluate bowel sounds

Correct answer: A

Rationale: Checking skin turgor and mucous membranes is the appropriate method to assess hydration status in a child with vomiting and diarrhea. Skin turgor is an indicator of skin elasticity, which decreases when an individual is dehydrated. Mucous membranes, such as the inside of the mouth, can also show signs of dehydration like dryness. Measuring blood glucose levels (choice B) is not relevant to assessing hydration status in this scenario. Assessing heart rate and blood pressure (choice C) is important in evaluating the overall condition of a child but may not directly indicate hydration status. Evaluating bowel sounds (choice D) is more related to assessing gastrointestinal function rather than hydration status.

4. What is a crucial aspect of managing a child with cystic fibrosis?

• A. High-sugar diet
• B. Daily chest physiotherapy
• C. Frequent use of antacids
• D. Limiting fluid intake

Correct answer: B

Rationale: Daily chest physiotherapy is crucial in managing cystic fibrosis as it helps clear mucus from the lungs, improves respiratory function, and reduces the risk of lung infections. High-sugar diets are not recommended for individuals with cystic fibrosis as they can contribute to mucus production, exacerbating respiratory issues. Frequent use of antacids is not a primary treatment for cystic fibrosis, as it does not address the underlying lung issues. Limiting fluid intake is not typically advised for individuals with cystic fibrosis, as adequate hydration is essential for maintaining lung function and thinning mucus secretions.

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

• A. Forced fluids
• B. Increased feedings
• C. Bed rest
• D. Frequent position changes

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.
