Correct Answer: C

Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This process helps in identifying any discrepancies or errors in the data. By cross-referencing with other sources, the nurse can verify the correctness of the data. Rationale: 1. Data validation checks the accuracy of the data by comparing it with external sources. 2. Data interpretation involves analyzing and making sense of the data, not comparing it with other sources. 3. Option A is incorrect because data validation typically comes after data collection and precedes data interpretation. 4. Option B is incorrect as validation does not specifically involve looking for patterns in professional standards. 5. Option D is incorrect because data interpretation focuses on understanding trends and insights from the data, not patterns in professional standards.

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.

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: Glucocorticoids and androgens. The adrenal cortex is divided into three layers, with the outer layer responsible for producing mineralocorticoids like aldosterone, the middle layer producing glucocorticoids like cortisol, and the inner layer producing androgens. Glucocorticoids are essential for regulating metabolism and immune response, while androgens are male sex hormones. Choices B, C, and D are incorrect because mineralocorticoids, catecholamines, norepinephrine, and epinephrine are produced by different parts of the adrenal gland, not specifically by the adrenal cortex.

Correct Answer: A

Rationale: The correct answer is A: Hearing loss, vertigo, and tinnitus. Meniere's disease is characterized by a triad of symptoms: recurrent episodes of vertigo, sensorineural hearing loss, and tinnitus. Vertigo is a spinning sensation, hearing loss affects the inner ear, and tinnitus is ringing in the ear. Nausea, vomiting, pain, nystagmus, or headache are not typically part of the classic triad of Meniere's disease symptoms. Therefore, option A is the most appropriate choice based on the specific symptomatology associated with Meniere's disease.
