Correct Answer: B

Rationale: The priority for a nurse working on an inpatient medical-surgical unit is to ensure client safety. This is crucial as errors in hospital care can lead to preventable deaths. While attending to holistic client needs and providing client-focused care are important aspects of nursing, ensuring client safety takes precedence to prevent harm and promote positive patient outcomes.

Correct Answer: C

Rationale: A large blood clot in the lungs will significantly impair gas exchange & oxygenation. Unless the clot is dissolved, this process will continue unabated.

Correct Answer: B

Rationale: The correct answer is B. A nurse should ask the client if they have any chronic breathing problems when the anteroposterior (AP) chest diameter is the same as the lateral chest diameter. This finding indicates a barrel chest, which can be associated with chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) or emphysema. Assessing for chronic breathing problems can help the nurse further evaluate the client's respiratory status and provide appropriate care.

Correct Answer: B

Rationale: Clients with an alteration in the CYP2C19 gene do not metabolize warfarin (Coumadin) well, leading to higher blood levels and more side effects. As this client is a poor candidate for warfarin therapy, the prescriber will most likely recommend the implantation of an inferior vena cava (IVC) filter. This device helps prevent blood clots from reaching the lungs, reducing the risk of pulmonary embolism.

Correct Answer: A

Rationale: Encouraging the client and family to be active partners in their healthcare is crucial for promoting safety. When clients and families actively participate, they are more likely to advocate for themselves, ask questions, and be engaged in their care, leading to better outcomes and reduced risks.
