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: Encouraging the client to sleep during the day can disrupt the normal sleep-wake cycle and is not recommended for managing insomnia associated with depression.

Choice B reason: Scheduling a brisk physical activity before bedtime can be stimulating and may actually make it more difficult for the client to fall asleep.

Choice C reason: Monitoring for bouts of diarrhea is not directly related to the care of a client with severe depression unless the client is on specific medications that may cause gastrointestinal upset as a side effect.

Choice D reason: Offering frequent small snacks can help manage the weight loss and decreased appetite often seen in clients with severe depression, ensuring they receive adequate nutrition.

Choice A reason: While disintegration indicates a pill is no longer stable, it is not specific to nitroglycerin tablets.

Choice B reason: The absence of a tingling sensation may not necessarily indicate that nitroglycerin tablets need to be replaced, as this sensation can vary.

Choice C reason: Nitroglycerin tablets should be replaced if they smell like vinegar, as this indicates that the medication may have degraded and may not be effective.

Choice D reason: Discoloration can occur due to various reasons and does not specifically indicate that nitroglycerin tablets have lost potency.
