A nurse is reinforcing teaching with a female client who is prescribed chlorpromazine.
Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale:

Shellfish is generally safe for clients taking MAOIs. However, it's important to ensure shellfish is fresh and properly refrigerated to avoid tyramine buildup due to spoilage.

Some individuals with shellfish allergies may need to avoid it regardless of MAOI use.

Choice B rationale:

Milk and milk products are typically safe for clients taking MAOIs.

However, some aged cheeses, such as cheddar, Swiss, and Parmesan, can contain high levels of tyramine and should be avoided.

Choice C rationale:

Canned tuna is generally safe for clients taking MAOIs.

However, it's essential to check labels carefully, as some brands may contain added tyramine-rich ingredients like soy sauce or fermented flavorings.

Choice D rationale:

Aged cheeses contain high levels of tyramine, an amino acid that can interact with MAOIs and cause a hypertensive crisis.

This is a potentially life-threatening condition characterized by a sudden and severe increase in blood pressure.

It's crucial for clients taking MAOIs to avoid all aged cheeses, including cheddar, Swiss, Parmesan, blue cheese, feta, and others.

Rationale for Choice A:

Diuretics are not routinely prescribed with lithium. While diuretics can increase the excretion of lithium, this can also lead to decreased lithium levels and potentially reduced effectiveness. Therefore, diuretics are generally only used in specific situations, such as when a client has lithium-induced edema or congestive heart failure. In such cases, the client's lithium levels would be closely monitored to ensure they remain within the therapeutic range.

Rationale for Choice B:

Weight gain is not a common manifestation of lithium toxicity. In fact, weight gain is a potential side effect of lithium therapy, but it is not typically associated with lithium levels reaching a toxic range. Other signs and symptoms of lithium toxicity include:

Tremor

Nausea and vomiting

Diarrhea

Confusion

Slurred speech

Ataxia

Seizures

Coma

Rationale for Choice C:

Monitoring lithium levels is essential to ensure that the client is receiving a therapeutic dose and to avoid toxicity. Lithium has a narrow therapeutic index, meaning that there is a small difference between the dose that is effective and the dose that is toxic. Regularly checking lithium levels allows the healthcare provider to adjust the dose as needed to maintain a safe and effective level.

The initial lithium level is typically checked within 3 to 5 days of starting the medication, and then periodically thereafter.

The frequency of monitoring may vary depending on the client's individual factors, such as age, kidney function, and other medications they are taking.

Rationale for Choice D:

Lithium is not typically discontinued after a specific period of time. It is often used as a long-term treatment for bipolar disorder to prevent the recurrence of manic and depressive episodes. The decision to discontinue lithium is made on a caseby-case basis, in consultation with the client and their healthcare provider.
