Correct Answer: C

Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This step ensures that the data is reliable and error-free. Option A is incorrect as data validation typically comes after data collection and cleaning, which precede data interpretation. Option B is incorrect as validation does not specifically focus on professional standards but rather on accuracy and consistency. Option D is incorrect as data interpretation involves analyzing and deriving insights from the validated data, not looking for patterns in professional standards.

Correct Answer: A

Rationale: The correct action is to report the ulcer to the admitting care provider first. This is essential because the ulcer could be a sign of an underlying infection or condition that needs immediate attention, especially in a hospitalized patient with pneumonia. Reporting the ulcer ensures prompt evaluation and appropriate treatment. The other options are incorrect because teaching about STD prevention and asking about syphilis assume the cause of the ulcer is related to a sexually transmitted infection, which may not be the case in this scenario. Additionally, cleaning the ulcer without proper assessment and diagnosis by a healthcare provider can lead to complications or delay in appropriate treatment.

Correct Answer: A

Rationale: The correct answer is A because monitoring the client's temperature before, during, and after the transfusion allows the nurse to identify any changes or trends that may indicate a complication related to the blood transfusion. This comprehensive monitoring helps differentiate between a normal body response to cold blood infusion and a potential adverse reaction. Choice B is incorrect because documenting the client's temperature only after the transfusion may miss important changes during the process. Choice C is incorrect as the temperature of the blood before transfusion does not directly indicate the client's response to the chilled blood. Choice D is incorrect as comparing the client's temperature with the temperature of the blood alone does not provide a complete picture of the client's condition throughout the transfusion process.

Correct Answer: A

Rationale: The correct choice is A: 18 gauge IV cannula for blood transfusion. Larger gauge allows for faster flow rate, crucial for transfusions to prevent clotting. 24, 22, and 28 gauge cannulas are too small for adequate blood flow, leading to potential complications like hemolysis or slowed infusion.

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.
