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: C

Rationale: Administering IV adenosine is the appropriate intervention for a client with symptomatic tachycardia to restore normal sinus rhythm. Adenosine is a medication used to treat supraventricular tachycardia (SVT) by interrupting the reentry pathways through the AV node and restoring normal sinus rhythm. It is a rapid-acting medication given as a rapid IV push followed by a saline flush. The dose is typically administered in a healthcare setting where cardiac monitoring is available due to its potential to cause transient asystole.

Correct Answer: C

Rationale: Crepitus (subcutaneous emphysema) around the insertion site can indicate air leakage, requiring immediate intervention to prevent complications such as pneumothorax. This assessment finding suggests that there may be a break in the chest tube system, leading to air entering the pleural space. Prompt intervention is crucial to prevent respiratory compromise and further complications.

Correct Answer: D

Rationale: The correct answer is D. A sudden drop in neutrophil count to below 500 indicates severe neutropenia, putting the client at high risk for infections. Neutrophils are essential for fighting off infections, and a significant decrease in their count can compromise the client's immune response. Immediate intervention is necessary to prevent the development of serious infections in the client with neutropenia.

Correct Answer: B

Rationale: Nitroglycerin is a medication that should be stored in a dark, glass container to protect it from light and moisture. Exposure to light and moisture can reduce its effectiveness. Storing it in a dark, glass container helps maintain the medication's stability and potency, ensuring that it remains safe and effective for use in emergencies, such as angina attacks.
