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 because measuring the wound and observing for redness, swelling, or drainage are essential steps in evaluating wound healing progress. Measuring the wound provides objective data on its size changes, while observing for signs of infection like redness, swelling, or drainage helps identify complications. - Choice A is incorrect because the nursing assistive personnel may not have the necessary knowledge to assess wound healing accurately. - Choice B is incorrect because documenting progress as "better" without objective data is subjective and does not provide a clear picture of the wound status. - Choice D is incorrect because leaving the dressing off can expose the wound to contaminants and compromise healing, making it a potentially harmful action.

Correct Answer: A

Rationale: Step 1: Pulmonary edema is caused by fluid accumulation in the lungs due to increased pressure in the pulmonary vasculature. Step 2: Decreased left ventricular pumping leads to congestive heart failure, causing increased pressure in pulmonary circulation. Step 3: This increased pressure forces fluid from the capillaries into the alveoli, causing pulmonary edema. Step 4: Increased left atrial contractility (B) would not directly lead to pulmonary edema. Step 5: Decreased right ventricular elasticity (C) and increased right atrial pressure (D) are not directly related to the pathophysiology of pulmonary edema. Summary: The correct answer is A because decreased left ventricular pumping directly contributes to the increased pressure in the pulmonary circulation that leads to pulmonary edema. Choices B, C, and D do not align with the primary underlying disorder of pulmonary edema.

Correct Answer: A

Rationale: The correct answer is A: Increased ICP. Decreasing level of consciousness is a classic sign of increased intracranial pressure (ICP) due to the compression of the brain. As ICP rises, it impairs cerebral perfusion leading to altered mental status. Parasympathetic response (B) and sympathetic response (C) are related to autonomic nervous system functions, not consciousness. Increased cerebral blood flow (D) might lead to conditions like hyperemia but does not directly cause a decreased level of consciousness.

Correct Answer: C

Rationale: Subjective data are information reported by the patient that cannot be measured or observed directly. In this case, nausea and abdominal pain are symptoms that can only be described by the patient, making them subjective data. Vomiting, pulse rate, respirations, blood pressure, pale skin, and thick toenails are all objective data, as they can be measured or observed directly by the healthcare provider. Therefore, choice C is the correct answer as it represents subjective data.
