Correct Answer: C

Rationale: Administering on-call sedation is crucial before a bronchoscopy to ensure the client is comfortable and adequately prepared for the procedure. Sedation helps reduce anxiety, discomfort, and ensures the client remains still during the bronchoscopy, enabling the healthcare provider to perform the procedure effectively.

Correct Answer: C

Rationale: Placing the client in Trendelenburg position should be the initial action as it can help manage a suspected air embolism, a potential complication of TPN administration. This position helps trap air in the apex of the atrium, reducing the risk of air reaching the pulmonary circulation and causing further harm. Once the client is in a safe position, further actions such as stopping the TPN infusion, notifying the healthcare provider, and administering oxygen can be taken as appropriate.

Correct Answer: D

Rationale: Monitoring the intravenous site hourly is essential to identify early signs of extravasation, such as swelling or pain, which can help prevent tissue damage. Prompt detection allows for immediate intervention, minimizing the risk of serious complications associated with vesicant extravasation.

Correct Answer: B

Rationale: In this scenario, the nurse should assess pulses, paresthesia, and paralysis distal to the right knee to evaluate for neurovascular compromise. This assessment helps determine the perfusion and sensation of the lower extremity, which is crucial in identifying potential vascular or nerve damage that may be causing the client's symptoms.

Correct Answer: C

Rationale: In this scenario, it is crucial to maintain the client's confidentiality while ensuring her safety. Contacting a person chosen by the client to remove the weapon from her home is the best course of action. This approach respects the client's autonomy and helps reduce the risk of harm without involving external authorities unnecessarily.
