A client with bipolar disorder is prescribed lithium carbonate (Lithobid). Which of the following laboratory values should be monitored regularly while taking this medication?

Blood glucose levels

Serum potassium levels

Serum lithium levels

Serum calcium levels.

Answer and Explanation

The Correct Answer is C

Serum lithium levels should be monitored regularly while taking this medication because lithium has a narrow therapeutic range and can cause toxicity if the levels are too high or ineffective if the levels are too low. The normal range for serum lithium levels is 0.6 to 1.2 mEq/L (0.6 to 1.2 mmol/L).

Choice A is wrong because blood glucose levels are not affected by lithium and do not need to be monitored regularly.

Choice B is wrong because serum potassium levels are not affected by lithium and do not need to be monitored regularly.

Choice D is wrong because serum calcium levels are not affected by lithium and do not need to be monitored regularly.

Correct Answer is C

Explanation

Renal function tests should be monitored periodically while the client is taking lithium carbonate (Lithobid).This is because lithium can cause renal impairment and electrolyte imbalances, which can affect the kidney function and increase the risk of lithium toxicity. Renal function tests can include blood urea nitrogen (BUN), creatinine, and urine specific gravity.

Choice A is wrong because thyroid function tests are not routinely required for clients taking lithium carbonate.However, lithium can cause hypothyroidism in some cases, so thyroid function tests may be done if the client has symptoms of low thyroid hormone levels, such as fatigue, weight gain, or cold intolerance.

Choice B is wrong because liver function tests are not necessary for clients taking lithium carbonate.Lithium does not affect the liver enzymes or cause liver damage.

Choice D is wrong because coagulation studies are not relevant for clients taking lithium carbonate.Lithium does not affect the blood clotting factors or increase the risk of bleeding.

A. Report any signs of rash immediately. B. Take this medication with food. C. Use a reliable form of birth control while taking this medication. D. Expect to see therapeutic effects within 1 week. E. Avoid grapefruit juice while taking this medication.

Correct Answer is ["A"]

Explanation

Lamotrigine can cause a serious and potentially life-threatening skin reaction called Stevens-Johnson syndrome, which causes flu-like symptoms, followed by a red or purple rash that spreads and forms blisters.This is more likely to happen in the first 8 weeks of starting lamotrigine, or when the dose is increased too quickly. Therefore, the nurse should instruct the client to report any signs of rash immediately and stop taking the medication until further evaluation.

Choice B is wrong because lamotrigine can be taken with or without food. Taking it with food does not affect its absorption or effectiveness.

Choice C is wrong because lamotrigine does not affect hormonal contraceptives, and vice versa.However, the nurse should advise the client to inform their doctor if they are pregnant or planning to become pregnant, as lamotrigine may have some risks for the fetus.

Choice D is wrong because lamotrigine may take several weeks or months to show therapeutic effects, depending on the condition being treated. The nurse should encourage the client to be patient and adhere to the prescribed regimen.

Choice E is wrong because lamotrigine does not interact with grapefruit juice.However, the nurse should advise the client to avoid alcohol, as it may increase the risk of side effects such as drowsiness, dizziness, and seizures.
