Metabolic acidosis

Respiratory acidosis

Metabolic alkalosis

Answer and Explanation

The Correct Answer is C

Choice A reason: Respiratory alkalosis is typically associated with hyperventilation, which is not common in acute pulmonary edema.

Choice B reason: Metabolic acidosis can occur in pulmonary edema due to tissue hypoxia and lactic acid production, but respiratory acidosis is more directly related to the primary problem of gas exchange.

Choice C reason: Respiratory acidosis is likely in acute pulmonary edema due to impaired gas exchange and CO2 retention.

Choice D reason: Metabolic alkalosis is not typically associated with acute pulmonary edema and is less likely than respiratory acidosis in this context.

Correct Answer is A

Explanation

Choice A Reason:Coronary artery bypass graft surgery (CABG) is not primarily performed to increase blood flow to the myocardium. Instead, it aims to restore blood flow to areas of the heart affected by blockages.

Choice B Reason:CABG does not intentionally decrease blood flow to the coronary arteries. On the contrary, it creates a new pathway to bypass blocked or partially blocked coronary arteries, improving blood flow to the heart muscle.

Choice C Reason:The primary purpose of CABG is to treat coronary artery disease by restoring blood flow to areas of the heart that aren't receiving enough blood. It involves using healthy blood vessels (usually from the chest or leg) to create a detour around blockages. By doing so, CABG improves heart function and reduces symptoms related to ischemia.

Choice D Reason:While CABG can indirectly prevent spasms of the coronary arteries by improving blood flow, it is not its primary purpose.

A. The client is hostile and sarcastic towards the staff. B. The client gives personal items and money away to other clients. C. The client paces in the hallway during the day and most of the night. D. The client demonstrates flight of ideas.

Correct Answer is C

Explanation

Choice A reason: While hostility and sarcasm can be challenging, they are not immediate safety concerns compared to the physical activity that could lead to exhaustion or injury.

Choice B reason: Giving away personal items and money can be concerning for the client's financial well-being, but it does not pose an immediate risk to their physical health.

Choice C reason: Pacing in the hallway during the day and most of the night could indicate a high level of psychomotor agitation associated with mania, which can lead to physical exhaustion or injury and is therefore a priority.

Choice D reason: Flight of ideas is a symptom of mania that, while important to note, does not pose an immediate risk to the client's safety like excessive physical activity does.
