Correct Answer: D

Rationale: The correct action for the nurse to take when continuous bubbling is noted in the water seal chamber of a chest tube is to apply a dressing over the insertion site. Continuous bubbling indicates an air leak, and applying a dressing helps manage this issue by providing a seal. Clamping the chest tube or replacing the drainage system is not appropriate in this situation as it can lead to complications such as tension pneumothorax or inadequate drainage of the pleural space.

Correct Answer: B

Rationale: The correct answer is B: Vision changes. Vision changes are a classic sign of digoxin toxicity and should be reported immediately to the provider for further evaluation and management. A heart rate of 78/min, a respiratory rate of 16/min, and a blood pressure of 120/80 mm Hg are within normal ranges and are not typically associated with digoxin toxicity. Therefore, they would not be the priority findings to report in this situation.

Correct Answer: C

Rationale: The correct action to reduce the risk of aspiration during enteral feedings is to elevate the head of the bed to 45 degrees. This position helps prevent the reflux of feeding into the lungs. Administering the feeding over 60 minutes (Choice A) does not directly reduce the risk of aspiration. Positioning the client in a supine position (Choice B) increases the risk of aspiration as it promotes reflux. Flushing the feeding tube with water (Choice D) is important for tube patency but does not directly reduce the risk of aspiration.

Correct Answer: C

Rationale: The correct answer is C: Tetanus diphtheria and acellular pertussis (Tdap) vaccine. The Tdap vaccine can be safely administered during pregnancy to protect both the mother and the newborn against whooping cough. Choices A, B, and D are incorrect because the Varicella vaccine, Inactivated polio vaccine, and Inactivated influenza vaccine are generally not recommended during pregnancy due to safety concerns.

Correct Answer: C

Rationale: The correct first action for the nurse to take after realizing that the wrong medication has been administered to a client is to monitor vital signs. Monitoring vital signs is crucial as it allows the nurse to promptly assess for any immediate adverse effects that may result from the wrong medication. This immediate assessment is essential for ensuring the client's safety and well-being. Notifying the provider (choice A) and reporting the incident to the nurse manager (choice B) are important steps to take, but they should come after ensuring the client's immediate safety. Filling out an incident report (choice D) is also necessary but should be done after addressing the client's immediate needs.
