A nurse is providing education for a client who has a genital herpes infection. Which of the following statements should the nurse include in the teaching?

Choice A rationale:

The recommended course of varenicline is longer than 30 days.

Choice B rationale:

Varenicline should be started 1 week before the client's quit date to allow the medication to reach effective levels.

Choice C rationale:

Drowsiness is not a common side effect of varenicline.

Choice D rationale:

Grapefruit interactions are not typically associated with varenicline.

Choice A rationale:

Agitation is a common manifestation of delirium, as the client experiences a disturbance in attention, awareness, and cognition. The client may become restless, irritable, or aggressive due to the altered mental state.

Choice B rationale:

Slow, flat speech is not a manifestation of delirium, but rather a sign of depression or dementia. Clients with delirium may have rapid, incoherent, or slurred speech, depending on the cause and severity of the condition.

Choice C rationale:

Visual hallucinations are another manifestation of delirium, as the client may perceive things that are not there or misinterpret sensory stimuli. The client may also have auditory or tactile hallucinations, which can contribute to the agitation and confusion.

Choice D rationale:

Confusion is a hallmark manifestation of delirium, as the client has difficulty with orientation, memory, and reasoning. The client may not recognize familiar people or places, or may have fluctuating levels of consciousness. The confusion may worsen at night or in low-light settings, which is known as sundowning syndrome.

Choice E rationale:

Rapid mood swings are also a manifestation of delirium, as the client may exhibit emotional lability, anxiety, depression, fear, or anger. The mood changes may be unpredictable and inappropriate to the situation.
