Correct Answer: D

Rationale: The correct answer is D because individuals with AB blood type are considered universal recipients, meaning they can receive blood from any blood type without risking complications due to incompatibility. This is because their blood cells have both A and B antigens and do not produce antibodies against either type. Therefore, the client can safely receive blood from types A, B, AB, or O without adverse reactions. Choices A, B, and C are incorrect because they limit the options for blood transfusion based on the client's AB blood type, which is not necessary given the unique nature of AB blood as universal recipients.

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: 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: B

Rationale: The correct answer is B: Hemorrhage. The nurse manager would intervene because hemorrhage is a life-threatening condition requiring immediate attention. Wandering (A), urinary retention (C), and impaired swallowing (D) are important assessments but do not pose the same level of immediate risk as hemorrhage. The nurse manager would prioritize addressing the hemorrhage to ensure the patient's safety and well-being.

Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. In acute Addisonian crisis, the adrenal glands do not produce enough cortisol and aldosterone, leading to electrolyte imbalances. This results in increased potassium levels (hyperkalemia) due to lack of aldosterone to promote potassium excretion. Hypernatremia (choice B) is less likely as aldosterone deficiency leads to sodium loss. Reduced BUN (choice C) is unlikely as Addison's crisis does not directly affect urea levels. Hyperglycemia (choice D) is not typically seen in Addisonian crisis as cortisol deficiency usually results in hypoglycemia.
