Marge is a 68-year-old woman with a long history of bipolar disorder. She is brought to the ED by her sister, who reports that Marge has been increasingly agitated, unable to sleep, and told her daughter that the mayor was calling her for advice on running the city. The behavior is an example of:

Choice A reason: Directly asking the client about suicidal plans is a critical step in assessing risk and determining the need for immediate intervention.

Choice B reason: While involving the family is important, it does not address the immediate risk the client may pose to herself.

Choice C reason: Recognizing the statement as a manipulation attempt is inappropriate; all expressions of suicidal ideation should be taken seriously.

Choice D reason: Allowing the client to rest does not address the immediate risk of suicide and the need for urgent assessment and intervention.

Choice A reason: Furosemide is a loop diuretic that can cause hypokalemia, so monitoring potassium levels is important.

Choice B reason: While calcium levels can be affected by furosemide, it is not typically the primary concern.

Choice C reason: Prothrombin time is not usually affected by furosemide and is not routinely monitored unless the patient is on anticoagulant therapy.

Choice D reason: Urine sodium could be checked, but it is the serum potassium that is most commonly monitored due to the risk of hypokalemia with furosemide use.
