Correct Answer: C

Rationale: The correct answer is C: 'Avoid open flames or smoking near oxygen.' This information is crucial to prevent fire hazards as oxygen supports combustion. Choices A, B, and D are incorrect. Increasing the oxygen flow rate without healthcare provider's instructions can be dangerous. Oxygen should not be turned off when not in use as prescribed by the healthcare provider, and storing oxygen tubing near heat sources poses a risk of fire.

Correct Answer: B

Rationale: Increased heart rate is a common sign of fluid volume deficit (FVD) as the body compensates for decreased fluid levels. When a client is experiencing FVD, the body tries to maintain perfusion to vital organs by increasing the heart rate. This compensatory mechanism helps to improve cardiac output and maintain blood pressure. Choices A, C, and D are incorrect because in FVD, hematocrit may be increased due to hemoconcentration, blood pressure tends to decrease as a compensatory response to FVD, and respiratory rate is usually unaffected or may increase due to attempts to maintain oxygenation.

Correct Answer: A

Rationale: The correct answer is A: Negligence. Negligence in nursing occurs when a healthcare provider fails to take appropriate action that a reasonably prudent provider would take in a similar situation, such as not notifying the provider of changes in a client's condition. In this scenario, the nurse's failure to inform the provider of the client's changed condition constitutes negligence. Choices B, C, and D are incorrect. Assault involves the intentional threat of bodily harm to another person, battery is the intentional harmful or offensive touching of another person without their consent, and defamation is the act of making false statements about someone to a third party that harms that person's reputation.

Correct Answer: B

Rationale: Verifying tube placement is the priority action the nurse should take before administering enteral feedings. This step ensures that the NG tube is correctly positioned, reducing the risk of complications such as aspiration pneumonia. Flushing the tube with water, elevating the head of the bed, and measuring residual gastric volume are important steps in enteral feeding administration but come after verifying tube placement. Flushing the tube with water helps clear the tubing, elevating the head of the bed reduces the risk of aspiration, and measuring residual gastric volume helps assess the client's tolerance to feedings.

Correct Answer: B

Rationale: The correct answer is B: Client's response to pain medication. When transferring a client to another unit, it is crucial to communicate how the client is responding to pain medication to ensure continuity of care and appropriate pain management. While nutritional status, daily vital signs, and most recent lab results are important aspects of the client's care, the client's response to pain medication directly impacts their comfort and well-being during the transfer process.
