A nurse is reinforcing teaching with a client about manifestations of lithium toxicity. Which of the following manifestations should the nurse include in the teaching?

Loss of appetite

vomiting and diarrhea

increased flatulence

Increased urination

Answer and Explanation

The Correct Answer is B

A. Loss of appetite is not a specific manifestation of lithium toxicity. However, gastrointestinal symptoms like nausea and vomiting can contribute to a decreased appetite.

B. Vomiting and diarrhea.
Lithium is a mood stabilizer commonly used in the treatment of bipolar disorder. Toxicity can occur, and symptoms can range from mild to severe. Vomiting and diarrhea are common early signs of lithium toxicity. As toxicity progresses, it can lead to more severe symptoms, such as tremors, confusion, and potentially life-threatening complications.

C. Increased flatulence is not a typical manifestation of lithium toxicity. Gastrointestinal symptoms associated with lithium toxicity are more likely to include nausea, vomiting, and diarrhea.

D. Increased urination is not a typical manifestation of lithium toxicity. Lithium can affect renal function, leading to decreased urine output, but it does not typically cause increased urination as a sign of toxicity.

Correct Answer is A

Explanation

A. Potassium 2.8 mEq/L
Hypokalemia (low potassium) is a critical finding and a priority in individuals with a history of bulimia nervosa, as it can lead to life-threatening complications such as cardiac arrhythmias and muscle weakness. Frequent vomiting and laxative use, common behaviors in bulimia nervosa, can result in significant potassium loss. A potassium level of 2.8 mEq/L is significantly below the normal range and requires immediate attention.

B. Serum chloride 96 mEq/L: While this value is within the normal range, it should be monitored. However, it is not as critical as addressing severe hypokalemia.

C. Hemoglobin (Hgb) 11 g/dL: This hemoglobin level is within the normal range and does not require immediate attention. It may be influenced by factors other than bulimia nervosa, and addressing hypokalemia is more urgent.

D. Serum amylase 240 units/L: Elevated amylase levels may indicate pancreatic inflammation, which could be related to bulimia nervosa, but it is not as urgent as addressing severe hypokalemia. The priority is managing the life-threatening electrolyte imbalance first.

A. "Avoid foods that contain tyramine." B. "Plant to discontinue this medication as soon as your depression is relieved." C. "Expect that your mood might take one to three weeks to begin improving." D. "Stop taking this medication if weight loss or gain occurs."

Correct Answer is C

Explanation

A. "Avoid foods that contain tyramine" is not relevant to fluoxetine. Tyramine restriction is a concern with certain medications, such as monoamine oxidase inhibitors (MAOIs), but not with SSRIs like fluoxetine.

B. "Plan to discontinue this medication as soon as your depression is relieved" is not advisable. Discontinuing an antidepressant abruptly can lead to withdrawal symptoms and may not allow for the full resolution of depressive symptoms. The decision to discontinue medication should be made in consultation with a healthcare provider.

C. "Expect that your mood might take one to three weeks to begin improving" is a crucial piece of information to provide because fluoxetine, a selective serotonin reuptake inhibitor (SSRI), often takes a few weeks to start exerting its therapeutic effects. It's important for the client to understand that the full benefits of the medication may not be felt immediately.

D. "Stop taking this medication if weight loss or gain occurs" is not an appropriate instruction. Weight changes are potential side effects of fluoxetine, but the decision to continue or discontinue the medication should be based on consultation with a healthcare provider. Abruptly stopping medication without medical guidance can lead to withdrawal symptoms and is not recommended.
