Correct Answer is D
Explanation
A. "Decrease your daily sodium intake."
Incorrect Explanation: This instruction is appropriate for a client taking lithium carbonate.
Explanation: Lithium is a mood-stabilizing medication commonly prescribed for conditions like bipolar disorder. High levels of sodium can lead to increased lithium retention in the body, potentially raising the risk of toxicity. Advising the client to decrease their daily sodium intake helps prevent this.
B. "Take this medication 2 hours before a meal."
Incorrect Explanation: This instruction is not accurate for lithium carbonate.
Explanation: Lithium carbonate is typically taken with food or milk to help minimize stomach upset. Taking it on an empty stomach might increase the risk of gastrointestinal side effects.
C. "Limit foods containing tyramine."
Incorrect Explanation: This instruction is not directly relevant to lithium carbonate.
Explanation: Tyramine is a compound found in some foods and can interact with certain medications like monoamine oxidase inhibitors (MAOIs), but it is not a primary concern with lithium carbonate.
D. "Report swelling of the feet to your provider."
Correct Explanation: This instruction is appropriate for a client taking lithium carbonate.
Explanation: Lithium can lead to water retention, which might result in swelling, particularly in the feet and ankles. Reporting swelling is important as it can be an early sign of potential side effects or changes in kidney function.
Correct Answer is C
Explanation
A. Instruct the client to increase his fluid intake: While adequate fluid intake is generally important for various reasons, increasing fluid intake would not alter the orange-red discoloration caused by rifampin. This side effect is due to the drug's action on body fluids, not dehydration.
B. Prepare the client for dialysis: Dialysis is not indicated for the harmless orange-red discoloration caused by rifampin. Dialysis is typically used for clients with kidney failure or significant electrolyte imbalances, and it would not address this specific side effect.
C. Document this as an expected finding.
Explanation:
Rifampin, an antibiotic commonly used in the treatment of tuberculosis (TB), can cause a harmless side effect known as "orange-red discoloration." This can affect bodily fluids such as urine, sweat, and tears. This is not a harmful effect and does not indicate a need for any specific intervention. Therefore, the nurse should document this as an expected finding due to the client's use of rifampin.
D. Check the client's liver function test results: The orange-red discoloration is not related to liver function, so checking liver function test results would not provide relevant information about this particular side effect.
