A nurse is assessing a client who is receiving intravenous therapy. The nurse should identify which of the following findings as a manifestation of fluid volume excess?

Choice A Reason:
Hypomagnesemia is incorrect. Lithium therapy itself is not a direct cause of hypomagnesemia. While exercise can affect magnesium levels to some extent, it's not a primary electrolyte imbalance that is typically associated with lithium use or considered a significant concern specifically due to lithium.
Choice B Reason:
Hypocalcemia is incorrect. Similarly, lithium therapy is not a direct cause of hypocalcemia. Exercise can affect calcium metabolism, but it's not a primary electrolyte imbalance typically associated with lithium use or considered a significant concern specifically due to lithium.
When a client taking lithium begins a new exercise program, the nurse should primarily assess for the risk of:
Choice C Reason:
Hyponatremia is correct. Lithium can affect the body's regulation of sodium, and excessive sweating due to increased exercise can lead to sodium loss. This combination can potentially contribute to the development of hyponatremia (low sodium levels). Therefore, when a client on lithium starts a new exercise regimen that may induce sweating, monitoring for signs of hyponatremia becomes crucial. Symptoms of hyponatremia can include confusion, headaches, nausea, and in severe cases, seizures or coma.
Choice D Reason:
Hypokalemia is incorrect. Lithium itself does not commonly cause hypokalemia. Exercise can lead to potassium loss through sweating, but hypokalemia is not the primary electrolyte imbalance typically associated with lithium use or considered a significant concern specifically due to lithium.

Choice A Reason:
"You should report monthly to have your blood drawn to monitor kidney function while taking medication." Is incorrect. While monitoring kidney function might be necessary during tuberculosis treatment due to potential medication side effects, monthly blood draws specifically for kidney function might not be standard. However, periodic blood tests to monitor various parameters, including kidney function, are part of tuberculosis treatment monitoring.
Choice B Reason:
"You will need to take two or more medications to treat your disease." Is correct. Treatment for active pulmonary tuberculosis typically involves a combination of antimicrobial medications to effectively treat the infection and prevent antibiotic resistance. This multidrug therapy is essential to combat the bacteria causing tuberculosis and reduce the risk of treatment failure or relapse.
Choice C Reason:
"You will need to undergo tuberculin skin tests every 6 months while taking medication for your disease." Is incorrect. Tuberculin skin tests are used for screening or diagnosing tuberculosis but are not typically repeated every six months during active treatment for the disease.
Choice D Reason:
"You should anticipate taking medication to treat your disease for at least the next 3 years." Is incorrect. The duration of treatment for active pulmonary tuberculosis varies but is typically shorter than three years. Treatment duration usually lasts several months to a year, depending on the specific medication regimen and the response to treatment.
