Correct Answer: C

Rationale: The correct answer is C because prevention emphasizes the importance of personal behavior in maintaining health. It highlights the role of individual choices in preventing diseases and promoting well-being. A is incorrect because prevention focuses on proactive measures rather than treating external factors. B is incorrect as it contradicts the importance of prevention in reducing preventable deaths. D is incorrect because prevention is about avoiding health issues before they occur, not treating them after they have developed.

Correct Answer: B

Rationale: Step 1: The patient has a history of hypertension and diabetes, putting them at risk for cardiovascular complications. Step 2: Among the choices, stroke is a common complication associated with uncontrolled hypertension and diabetes. Step 3: Monitoring for signs of stroke is crucial to prevent serious consequences in this patient population. Step 4: Hyperglycemia (A) is a common complication of diabetes, but it is not directly related to the patient's hypertension. Step 5: Hypokalemia (C) is an electrolyte imbalance that can occur in some conditions but is not as directly linked to the patient's history. Step 6: Hypoglycemia (D) is a potential complication in diabetic patients but is not as common as hyperglycemia and is not directly related to hypertension.

Correct Answer: B

Rationale: The correct answer is B: Inspection. This is because visual observation is typically the initial step in a physical assessment to gather information about the patient's overall appearance, skin color, posture, and any obvious abnormalities. Palpation (A) involves touching and feeling for abnormalities, which usually follows inspection. Percussion (C) is the technique of tapping on the body to assess underlying structures, and auscultation (D) is listening to sounds produced by the body, both of which typically come after inspection and palpation. Inspecting the patient first allows the nurse to establish a baseline before moving on to more detailed assessment techniques.

Correct Answer: B

Rationale: The correct answer is B because encouraging deep breathing and coughing exercises helps to improve lung function and prevent complications in pneumonia. This intervention can help clear secretions, improve oxygenation, and prevent respiratory distress. Administering antibiotics (choice A) is important but not the priority for immediate patient care. Providing pain relief (choice C) is essential but addressing respiratory function is more critical. Monitoring oxygen saturation levels (choice D) is necessary, but promoting lung function through exercises takes precedence.

Correct Answer: B

Rationale: The correct answer is B: Respiratory failure. Patients with COPD have impaired lung function, making them at risk for respiratory failure due to inadequate oxygenation. This can occur due to exacerbation of COPD, infections, or other factors. Monitoring for signs of respiratory distress is crucial. A: Pneumonia - While patients with COPD are at higher risk for pneumonia due to impaired lung function, respiratory failure is a more immediate and critical complication to monitor for in this scenario. C: Hypoglycemia - COPD does not directly increase the risk of hypoglycemia, so monitoring for this complication is not a priority in this case. D: Hypertension - Although some patients with COPD may have hypertension, it is not a common complication directly related to COPD. Monitoring for respiratory failure is more essential in this situation.
