Correct Answer: B

Rationale: The correct answer is B because the right side weakness indicates a lesion in the left hemisphere of the brain. The brain's motor functions are contralaterally controlled, meaning the left hemisphere controls the right side of the body. Therefore, a right-sided weakness suggests a lesion in the left hemisphere. The other choices are incorrect because expressive aphasia is associated with left hemisphere lesions, judgment of distance and proprioception are more related to parietal lobe lesions, and orientation to time and space is not directly linked to right-sided weakness.

Correct Answer: B

Rationale: The correct answer is B: Fluid retention and weight gain. Prednisone is a corticosteroid that can cause fluid retention and weight gain as common adverse reactions. Here's the rationale: Prednisone is known to increase sodium and water retention in the body, leading to fluid retention and subsequent weight gain. This occurs due to the drug's impact on the body's electrolyte balance. Tetany and tremors (Choice A) are not common adverse reactions associated with prednisone use. Anorexia and weight loss (Choice C) are also not typical reactions, as prednisone is more likely to cause weight gain. Choice D, "None of the above," is incorrect as prednisone commonly causes fluid retention and weight gain as adverse reactions.

Correct Answer: A

Rationale: The correct answer is A. First, the nurse should assess the chest-drainage system and tubing for any air leaks. Air leaks can cause bubbling in the water-seal chamber, indicating a potential issue with the system's integrity. By examining the entire system, the nurse can identify and correct any leaks to ensure proper functioning of the chest-drainage system. Lowering the level of suction (choice B) may not address the underlying issue of air leaks. Doing nothing (choice C) is not appropriate as vigorous bubbling indicates a problem. Asking the patient to cough forcefully (choice D) is unrelated to addressing bubbling in the water-seal chamber.

Correct Answer: A

Rationale: The correct answer is A. Blood type A is considered the rarest because it is less common in the general population compared to other blood types. The rarity of blood type A is due to the combination of genetic factors that determine blood type. In contrast, blood types B and O are more common in the population, while blood type AB is considered the universal recipient type and is therefore not the rarest. Blood type A is less prevalent, making it the correct answer in this scenario.

Correct Answer: C

Rationale: The correct answer is C because data validation involves verifying the accuracy and consistency of data by comparing it with other reliable sources. This ensures that the data is correct and reliable for analysis. Choice A is incorrect because data validation typically occurs after data collection, which is followed by data interpretation. Choice B is incorrect because validation is not about professional standards but about verifying data accuracy. Choice D is incorrect because data interpretation focuses on deriving meaning and insights from data, not on professional standards. In summary, understanding the differences between data validation and interpretation is crucial for ensuring data accuracy and reliability.
