Correct Answer: B

Rationale: The correct answer is B because the nurse cannot promise confidentiality in this context. It is essential to prioritize the safety and well-being of the client and others. Certain information, such as harm to oneself or others, must be reported to ensure appropriate interventions are taken. Choice A is incorrect because while documentation is important, confidentiality cannot be guaranteed in this situation. Choice C is incorrect as the nurse should not make promises that may conflict with their professional responsibilities. Choice D is incorrect as reporting everything to the treatment team without discretion may breach client confidentiality.

Correct Answer: B

Rationale: The correct instruction for a client with GERD is to avoid lying down immediately after eating. This helps prevent stomach acid from flowing back into the esophagus, which can worsen symptoms. Eating large meals can actually increase acid production and exacerbate GERD. Limiting fluid intake with meals may be beneficial for some individuals, but it is not a key instruction for managing GERD. Drinking carbonated beverages can trigger reflux symptoms and should be avoided by individuals with GERD.

Correct Answer: B

Rationale: The correct answer is B: Start intravenous fluids at a fast rate. In a client with pheochromocytoma, the highest priority intervention is to ensure adequate intravascular volume before initiating any other treatment. This helps prevent a sudden drop in blood pressure that can occur due to the release of catecholamines during tumor manipulation. While monitoring blood pressure frequently is essential, ensuring adequate intravascular volume takes precedence. Administering pain medication and antihypertensive medications are important but are not the highest priority in the initial management of pheochromocytoma.

Correct Answer: A

Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.

Correct Answer: D

Rationale: A decrease in respiratory rate indicates that the client's breathing is becoming more stable, which suggests an improvement in their condition. Respiratory rate is a critical indicator of respiratory status and oxygenation. Increased white blood cell count (choice A) suggests ongoing infection, crackles on lung auscultation (choice B) indicate fluid in the lungs, and productive cough with green sputum (choice C) may indicate persistent infection or airway inflammation, which do not necessarily reflect improvement in pneumonia.
