Correct Answer: B

Rationale: Step 1: Crowded living conditions do not directly increase the risk of lung cancer. Step 2: Passive smoke (choice A) and air pollution (choice C) contain carcinogens linked to lung cancer. Step 3: Diet low in fruits and vegetables (choice D) may lead to poor immune function, potentially impacting cancer risk. Step 4: In summary, crowded living conditions do not contribute to lung cancer risk compared to the other choices.

Correct Answer: C

Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to gather comprehensive data about the patient's health status, including vital signs, physical appearance, and potential health issues. It provides valuable information for developing an individualized care plan. Reviewing literature (A) is important but not for establishing a patient's database. Checking orders (B) and ordering medications (D) are part of the treatment process and do not directly contribute to establishing the initial patient database.

Correct Answer: C

Rationale: The correct answer is C: 15 to 20 g of a fast-acting carbohydrate such as orange juice. In this scenario, the client is experiencing hypoglycemia, which can lead to confusion and abnormal behavior. Administering fast-acting carbohydrates like orange juice will help quickly raise the blood sugar levels. This is the first-line treatment for conscious patients with hypoglycemia. Choice A (I.M. or subcutaneous glucagon) is used for unconscious patients or when oral intake is not possible. Choice B (I.V. bolus of dextrose 50%) is too aggressive for a conscious patient and may lead to complications. Choice D (10 U of fast-acting insulin) would further lower the blood sugar levels and worsen the situation. Administering fast-acting carbohydrates is the safest and most effective approach for conscious patients with hypoglycemia to quickly raise their blood sugar levels and resolve their symptoms.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. In hypovolemia, the body compensates by increasing heart rate (B: Tachycardia) to maintain perfusion, decreasing urine output (C: Oliguria) to conserve fluid, and increasing respiratory rate (D: Tachypnea) to improve oxygenation. Hypertension is not a typical compensatory response to hypovolemia; instead, blood pressure tends to decrease due to reduced circulating volume. Therefore, hypertension is the symptom that would not be expected in a patient with hypovolemic shock.

Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. The nurse is utilizing assessment data to analyze and interpret the information to develop a nursing diagnosis. This involves critical thinking skills to make conclusions and create a plan of care. A: Assigning clinical cues - This choice is incorrect as it refers to identifying objective and subjective data during assessment, not the process of analyzing and synthesizing data to form a diagnosis. B: Defining characteristics - This choice is incorrect as it typically refers to the specific manifestations or symptoms associated with a particular nursing diagnosis, not the process of diagnosing itself. D: Diagnostic labeling - This choice is incorrect as it refers to the final step in the nursing diagnosis process where the nurse assigns a label to the identified problem, not the overall process of diagnostic reasoning.
