Correct Answer: D

Rationale: The correct answer is D because "Unable to palpate femoral pulse in left leg" is an objective finding that can be measured or observed without interpretation or bias. It provides concrete, measurable information about the patient's condition. Choices A, B, and C are subjective data as they rely on the patient's feelings, emotions, and perceptions, which can vary and are open to interpretation. Objective data is crucial in making accurate assessments and decisions in healthcare.

Correct Answer: A

Rationale: The correct answer is A because the nurse is using data validation by comparing the time of the last dressing change with the appearance of old and new drainage. This process ensures that the decision to remove the wound dressing is based on accurate and relevant information. By assessing both the time of the last dressing change and the characteristics of the drainage, the nurse is validating the need for the intervention. Option B is incorrect because administering pain medicine based solely on a patient's report of increased pain without further validation does not demonstrate data validation. Option C is incorrect as the nurse immediately requesting an order of potassium without further assessment of the patient's condition is not an example of data validation. Option D is incorrect as elevating a leg cast based solely on a patient's report of decreased mobility without further assessment does not involve data validation.

Correct Answer: C

Rationale: The correct answer is C: Eye opening, verbal response, motor response. The Glasgow Coma Scale assesses a patient's level of consciousness using these three factors. Eye opening measures arousal, verbal response assesses communication abilities, and motor response evaluates motor function. In the case of J.E., since he is alert and oriented, his eye opening is intact. His ability to communicate verbally and move his limbs appropriately would be crucial in determining his neurological status. Choices A and B are incorrect as they do not include the necessary assessment factor of eye opening. Choice D is incorrect as it mentions "response to pain" instead of verbal response, which is a key component of the Glasgow Coma Scale.

Correct Answer: B

Rationale: The correct answer is B: Perforation of the colon caused by the liver biopsy. The symptoms of fever, severe abdominal pain, and confusion are indicative of peritonitis, which can result from a bowel perforation during the liver biopsy procedure. Perforation of the colon can lead to leakage of bowel contents into the peritoneal cavity, causing inflammation, infection, and systemic symptoms. This is a serious complication that requires immediate medical attention. Incorrect options: A: Bleeding in the liver caused by the liver biopsy would present with symptoms such as hypotension and signs of internal bleeding, not confusion and severe abdominal pain. C: An allergic reaction to contrast media would typically present with symptoms such as rash, itching, or respiratory distress, not fever, severe abdominal pain, and confusion. D: Normal post procedural pain would not cause confusion and a change in the level of consciousness, which indicates a more serious underlying issue like bowel perforation.

Correct Answer: C

Rationale: The correct nursing diagnosis is C: Impaired skin integrity. This choice is correct because it directly addresses the bacterial infection in the left lower leg by focusing on the skin's condition. The patient's skin integrity is compromised due to the infection, making this nursing diagnosis appropriate. Choice A (Infection) is too broad and does not specify the impact on the skin. Choice B (Risk for infection) is incorrect because the patient already has a bacterial infection, so the risk has already manifested. Choice D (Staphylococcal leg infection) is too specific and does not address the broader issue of skin integrity. Therefore, the best choice is C as it accurately reflects the patient's current condition and guides appropriate nursing interventions to address the impaired skin integrity caused by the bacterial infection.
