Nursing Elites

1. How many vitamins are known to be required in the diet of human beings?

• A. 5
• B. 8
• C. 10
• D. 13

Correct answer: D

Rationale: The correct answer is D: 13. There are 13 essential vitamins required in the diet of human beings, including vitamins A, C, D, E, K, and the B vitamins. Choice A (5), Choice B (8), and Choice C (10) are incorrect because they do not represent the total number of essential vitamins needed by human beings.

2. What is one benefit of using controls in an experiment?

• A. The size of the groups does not matter.
• B. The subjects are unaware of the experiment's details.
• C. The subjects who are treated are balanced against the placebos.
• D. The subjects are similar in all respects except for the treatment being tested.

Correct answer: D

Rationale: The correct answer is D. Controls in an experiment ensure that the subjects are similar in all respects except for the treatment being tested. This allows for a fair comparison between the treatment group and the control group. Choice A is incorrect because the size of the groups is not the primary benefit of using controls. Choice B is incorrect as blinding, not controls, refers to subjects not knowing about the experiment. Choice C is incorrect as it pertains more to randomization than the use of controls.

3. 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.

4. How is gastroesophageal reflux (GER) typically treated in infants?

• A. Keeping the infant NPO
• B. Thickening the formula or breast milk with cereal
• C. Placing the infant to sleep on the side
• D. Switching the infant to cow's milk

Correct answer: B

Rationale: Thickening the formula or breast milk with cereal is a common treatment for gastroesophageal reflux (GER) in infants. By adding cereal, the feedings become heavier, making it less likely for the stomach contents to reflux. Keeping the infant NPO (nothing by mouth) is not typically necessary for GER treatment and might not be appropriate. Placing the infant to sleep on the side is not recommended due to the risk of sudden infant death syndrome (SIDS). Switching the infant to cow's milk is also not a recommended treatment for GER as it can exacerbate symptoms due to its protein content.

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

• A. Chance variation is less likely to affect the results.
• B. The possibility of a placebo effect is eliminated.
• C. The experiment will be double-blind.
• D. The control group will be similar to the experimental group.

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.
