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: 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: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.

Correct Answer: D

Rationale: The correct answer is D: 'Report any signs of respiratory depression immediately.' Respiratory depression is a severe side effect of opioids like oxycodone and can be life-threatening. It is crucial for the nurse to instruct the client to report any signs such as slow or shallow breathing, difficulty breathing, or confusion. Choice A is incorrect as taking oxycodone with or without food does not significantly affect its efficacy. Choice B is incorrect because avoiding driving is important due to the potential impairment caused by oxycodone, but reporting respiratory depression is more critical. Choice C is incorrect as increasing physical activity may not always be suitable for individuals with chronic back pain and is not directly related to preventing respiratory depression.

Correct Answer: D

Rationale: Administering prescribed antibiotics is crucial in treating MRSA infections. MRSA is a type of bacteria that is resistant to many antibiotics, including methicillin. Therefore, prompt administration of the appropriate antibiotics is essential to target the MRSA infection effectively. Encouraging increased oral fluids (Choice A) and providing high-protein snacks (Choice B) may be beneficial for overall recovery but are not the most important actions in treating an MRSA infection. Changing the wound dressing (Choice C) is important for wound care but does not directly address the infection caused by MRSA.
