An adult client is admitted to the critical care unit with systemic inflammatory response syndrome (SIRS) as a result of a postburn infection. The client has a long line peripherally inserted IV catheter for fluid and medication administration and current vital signs include temperature 102.8°F (39.3°C., heart rate 108 beats/minute, respirations 32 breaths/minute. Which action should the nurse implement first?

Choice A: Blood alcohol level of 0.09% (90 mmol/L) is not the most important finding for the nurse to report, as this is within the reference range and does not indicate alcohol intoxication or withdrawal, which can affect the client's mental status and mood stability. This is a distractor choice.

Choice B: Six hours of sleep in the past three days is not the most important finding for the nurse to report, as this is a common symptom of bipolar disorder during manic episodes and does not require immediate intervention by the health care provider. This is another distractor choice.

Choice C: Serum lithium level of 1.6 mEq/L (1.6 mmol/L) is the most important finding for the nurse to report, as this indicates lithium toxicity, which can cause neurological and renal impairment and potentially fatal complications such as seizures, coma, and cardiac dysrhythmias. Therefore, this is the correct choice.

Choice D: Weight loss of 10 pounds (4.5 kg) in past month is not the most important finding for the nurse to report, as this may be related to decreased appetite or increased activity during manic episodes and does not pose an immediate threat to the client's health or safety. This is another distractor choice.

Choice A reason: This is incorrect because instructing the client and family to reconsider end of life choices is disrespectful and insensitive. The nurse should respect the client's autonomy and preferences and support their decisions.

Choice B reason: This is correct because teaching the client how to use guided imagery is a helpful intervention for coping with feelings related to death and dying. Guided imagery is a relaxation technique that involves visualizing positive images and scenarios that can reduce stress, anxiety, and pain.

Choice C reason: This is correct because recording the client's desire to live is an important intervention for coping with feelings related to death and dying. The nurse should acknowledge and validate the client's emotions and help them express their hopes and fears.

Choice D reason: This is correct because encouraging family to visit frequently is a beneficial intervention for coping with feelings related to death and dying. The nurse should facilitate family involvement and communication and help the client maintain meaningful relationships.

Choice E reason: This is correct because encouraging family to bring the client old photographs is a useful intervention for coping with feelings related to death and dying. The nurse should assist the client in reminiscing and reviewing their life story and achievements.
