Adult Health 2 Final Exam

Correct Answer: D

Rationale: In advanced liver failure related to chronic alcoholism, ascites and edema occur due to multiple pathophysiological mechanisms. Portal hypertension contributes to the development of ascites by increasing pressure in the portal venous system. Sodium and water retention exacerbate fluid accumulation in the third space. Decreased serum albumin levels lead to reduced oncotic pressure, contributing to the movement of fluid into the interstitial spaces. Abnormal protein metabolism further disrupts fluid balance. Therefore, all of the options (A, B, and C) are correct in this scenario, making choice D the correct answer. Choices A, B, and C alone do not fully explain the comprehensive pathophysiological mechanisms involved in the development of ascites and edema in this clinical context.

Correct Answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

Correct Answer: B

Rationale: Encouraging increased fluid intake is the most appropriate intervention to promote airway clearance in a client with pneumonia. Adequate hydration helps to thin respiratory secretions, making it easier for the client to cough up and clear the airways. Administering bronchodilators (Choice A) may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy (Choice C) can be beneficial in certain cases but may not be the initial intervention for promoting airway clearance. Providing humidified oxygen (Choice D) can help improve oxygenation but does not specifically target airway clearance in pneumonia.

Correct Answer: D

Rationale: A comprehensive care plan for a client with depression should include multiple components to address various aspects of health. Regular physical activity can help improve mood and overall well-being. Scheduled sleep patterns are essential as sleep disturbances are common in depression and can worsen symptoms. Social interaction with family and friends provides emotional support and reduces feelings of isolation. Therefore, including all these aspects in the care plan can help support the client's recovery. Choice D, 'All of the above,' is the correct answer because all the options are important components of a holistic care plan for depression. Choices A, B, and C are incorrect because each of these elements plays a crucial role in managing depression.

Correct Answer: A

Rationale: The correct answer is A: To drain air and fluid from the pleural space. A chest tube is primarily used to remove accumulated air or fluid in the pleural space, preventing lung collapse or compromise of lung function. This intervention aims to re-expand the lung and enhance respiratory function. Choice B is incorrect because preventing infection is not the primary purpose of a chest tube. Choice C is incorrect as lung expansion is a result of draining the pleural space, not the primary goal. Choice D is incorrect as monitoring intrathoracic pressure is not the main objective of a chest tube insertion.
