Which statement by a nurse indicates a good understanding about the differences between data validation and data interpretation?

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: Inform the registered nurse. This is the best course of action as the LPN should escalate the situation to a higher level of care by involving the registered nurse who can further assess the patient's concerns and provide appropriate interventions. A. Reassuring the patient may not address the underlying fear and may not be sufficient to alleviate their anxiety. B. Providing statistics about surgery death rates may further escalate the patient's fears and anxiety, causing more harm than good. D. Involving the family to comfort the patient may not address the patient's specific concerns and may not be within the family's scope of understanding or expertise to effectively address the situation. Informing the registered nurse allows for a more comprehensive assessment and appropriate intervention to address the patient's fears and concerns in a holistic manner.

Correct Answer: B

Rationale: The correct answer is B: Redness of the upper part of the feet. During lymphangiography, a contrast dye is injected into the lymphatic vessels. This may cause temporary redness in the upper part of the feet due to the dye spreading throughout the lymphatic system. Purplish stools (A), bluish urine (C), and coldness of the soles (D) are not expected side effects of lymphangiography and do not have a direct correlation with the procedure.

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: 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: B

Rationale: Rationale: 1. NPH insulin peaks in 4-12 hours, making 4:00 PM the highest risk time. 2. 10:00 AM is too soon for peak effect. 3. Noon is too early for peak effect. 4. 10:00 PM is too late for peak effect. In summary, B is correct as it aligns with NPH insulin peak time, while other options are too early or too late.

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: 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: A

Rationale: The correct answer is A: Use aseptic technique for the insertion site. Aseptic technique is crucial for preventing infection when accessing or caring for an invasive monitoring system like a subdural intracranial pressure monitoring system. Aseptic technique involves maintaining a sterile field, washing hands, using sterile gloves, and using sterile supplies to minimize the risk of contamination. This is essential to prevent introducing harmful microorganisms into the patient's system. Using clean technique (B) or sterile technique only when cleansing the insertion site (C) may not provide adequate protection against infection. Closing leaks in the tubing with tape (D) is not an appropriate method for preventing infection and can lead to complications.
