A nurse is preparing to administer sertraline 50 mg PO once daily to a client who has depressive disorder.

Available is sertraline oral solution 20 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth.

Use a leading zero if it applies.

Do not use a trailing zero.).

Condition Most Likely Experiencing:

Delirium

• The client's acute confusion, restlessness, disorientation, and inability to perform basic tasks suggest delirium rather than dementia or normal aging. Delirium often has an underlying cause, such as infection or medication side effects, and requires immediate intervention.

Actions to Take:

Monitor for an underlying infection.

• Explanation: Infections, particularly urinary tract infections (UTIs) in older adults, are a common cause of delirium. Since the client has been incontinent, an infection could be contributing to the confusion. Identifying and treating the infection can help resolve symptoms.

Use symbols rather than written signs for directions.

• Explanation: Since the client is confused and struggling to recognize basic instructions (e.g., confusing the call light with the TV remote), visual cues like symbols can help them navigate their environment and follow instructions more easily.

Parameters to Monitor:

Presence of agnosia.

• Explanation: Agnosia (difficulty recognizing objects or their use) can indicate cognitive decline. The client mistaking a washcloth for something that belongs in a dryer suggests possible cognitive impairment, and tracking this symptom will help assess changes in mental status.

Ability to complete familiar tasks.

• Explanation: Monitoring whether the client can complete daily activities (e.g., using the call light correctly, self-care) will help determine if their confusion is improving or worsening over time.

Incorrect Choices and Explanations:

Anticipate a prescription for donepezil.

• Why Incorrect? Donepezil is used for Alzheimer’s disease, which develops gradually, unlike delirium, which is sudden and reversible if the cause is treated.

Anticipate a prescription for duloxetine.

• Why Incorrect? Duloxetine is an antidepressant. While depression can cause confusion, this case strongly suggests acute delirium rather than major depressive disorder.

Determine the date of the client’s last eye examination.

• Why Incorrect? Vision problems are not the primary concern in this case. The client's confusion is more likely related to delirium rather than visual impairment.

Night vision.

• Why Incorrect? While vision problems can impact safety, the client’s confusion is the main issue here, not their ability to see at night.

Attendance at group therapy.

• Why Incorrect? Group therapy is useful for conditions like depression or dementia but does not address the immediate, acute nature of delirium.

Oxygen saturation.

• Why Incorrect? The client’s oxygen saturation is already normal (97%), making it an unlikely cause of the delirium. The focus should be on potential infection or other triggers.

Choice A rationale:

While liver enzymes are important to monitor for many medications, they are not typically affected by lithium.

Choice B rationale:

Uric acid levels are not typically affected by lithium.

Choice C rationale:

Lithium can affect the sodium levels in the body, making it important to monitor these levels while taking this medication.

Choice D rationale:

Erythrocyte sedimentation rate is not typically affected by lithium.
