Correct Answer: A

Rationale: The correct answer is A: Inform the physician. This is essential because a sudden change in vital signs may indicate a critical condition that requires immediate medical attention. The physician needs to be informed promptly to assess the situation and provide appropriate interventions. Summary: - B: Changing environmental settings is not a priority when dealing with sudden changes in vital signs. - C: Altering diet intake is not an immediate response to sudden changes in vital signs. - D: Decreasing physical activity may not address the underlying cause of the sudden change in vital signs.

Correct Answer: A

Rationale: The correct answer is A: Increase fluid intake. This is important for a client undergoing radiation and chemotherapy for non-Hodgkin's lymphoma to prevent dehydration, help flush out toxins, and support kidney function. Increasing fluid intake can also help manage side effects like nausea and vomiting. Choices B, C, and D are incorrect because low-fat meals, soft bland foods, and foods rich in folic acid are not specifically indicated for clients undergoing radiation and chemotherapy for non-Hodgkin's lymphoma.

Correct Answer: C

Rationale: The correct answer is C: Non-mobile mass with irregular edges. A non-mobile mass with irregular edges is more likely to be cancerous as it indicates potential infiltration into surrounding tissues. This finding raises suspicion for malignancy as cancerous lumps tend to have irregular shapes due to their invasive nature. In contrast, options A and B describe characteristics of benign masses, such as mobile, soft, and easily delineated. Option D indicates no palpable lymph nodes, which does not directly correlate with the characteristics of the breast lump. Therefore, option C is the most concerning and indicative of a potentially cancerous lesion based on the assessment findings provided.

Correct Answer: C

Rationale: The correct answer is C: Pernicious anemia. Vitamin B12 is essential for the production of red blood cells, and its deficiency can lead to pernicious anemia, characterized by decreased red blood cell production. Without adequate vitamin B12, the body cannot properly utilize iron, leading to anemia. Iron deficiency anemia (choice A) is a result of insufficient iron levels, not vitamin B12 deficiency. Sickle cell anemia (choice B) is a genetic disorder affecting hemoglobin, not related to vitamin B12 deficiency. Acquired haemolytic anemia (choice D) is caused by the premature destruction of red blood cells, not by vitamin B12 deficiency.

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.
