A nurse accidentally administers the medication metformin instead of metoprolol to a client.
Which of the following actions should the nurse take?
Obtain the client’s HDL level.
Monitor the client’s thyroid function levels.
Collect the client’s uric acid level.
Check the client’s glucose level.
The Correct Answer is D
Metformin is a medication used to lower blood glucose levels in people with type 2 diabetes. Metoprolol is a beta-blocker used to treat high blood pressure and heart problems. If the nurse accidentally gives metformin instead of metoprolol, the client may experience hypoglycemia (low blood sugar), which can cause symptoms such as sweating, shakiness, confusion, and loss of consciousness. Therefore, the nurse should check the client’s glucose level and treat hypoglycemia if needed.
Choice A is wrong because HDL (high-density lipoprotein) is a type of cholesterol that is not affected by metformin or metoprolol.
Choice B is wrong because thyroid function levels are not affected by metformin or metoprolol.
Choice C is wrong because uric acid level is not affected by metformin or metoprolol.
Uric acid is a waste product that can cause gout if it accumulates in the joints. Normal ranges for blood glucose are 70 to 130 mg/dL before meals and less than 180 mg/dL two hours after meals.
Normal ranges for HDL are 40 to 60 mg/dL for men and 50 to 60 mg/dL for women.
Normal ranges for thyroid function levels vary depending on the specific test, but generally they are between 0.4 and 4.0 mIU/L for TSH (thyroid-stimulating hormone), 4.5 to 11.2 mcg/dL for T4 (thyroxine), and 80 to 180 ng/dL for T3 (triiodothyronine).
Normal ranges for uric acid are 3.4 to 7.0 mg/dL for men and 2.4 to 6.0 mg/dL for women.

Correct Answer is B
Explanation
Colesevelam is a bile acid sequestrant that lowers cholesterol by binding to bile acids in the intestine and preventing their reabsorption into the bloodstream. Some possible explanations for the other choices are:
Choice A. Chlorpromazine is wrong because it is an antipsychotic medication that has no effect on cholesterol levels.
Choice C. Colchicine is wrong because it is an anti-inflammatory drug that is used to treat gout and other inflammatory conditions, not high cholesterol.
Choice D. Cimetidine is wrong because it is a histamine H2 receptor antagonist that reduces stomach acid production and is used to treat ulcers and gastroesophageal reflux disease (GERD), not high cholesterol.
Normal ranges for cholesterol levels vary depending on the type of cholesterol and the risk factors of the individual, but generally, total cholesterol should be less than 200 mg/dL, LDL cholesterol should be less than 100 mg/dL, HDL cholesterol should be more than 40 mg/dL for men and 50 mg/dL for women, and triglycerides should be less than 150 mg/dL.
Correct Answer is D
Explanation
This is because swelling of the feet can be a sign of lithium toxicity, which is a serious condition that can occur when the level of lithium in the blood is too high. Lithium toxicity can cause confusion, irregular heartbeat, muscle weakness, and kidney problems. Therefore, the client should report any signs of lithium toxicity to their provider as soon as possible.
Choice A is wrong because limiting foods containing tyramine is not necessary for clients taking lithium. Tyramine is a substance found in some foods that can interact with certain antidepressants called monoamine oxidase inhibitors (MAOIs), but not with lithium.
Choice B is wrong because decreasing the daily sodium intake can actually increase the risk of lithium toxicity.
Sodium helps to regulate the amount of lithium in the body, so if the sodium level is low, the lithium level can rise too high.
The client should maintain a normal sodium intake and drink enough fluids while taking lithium.
Choice C is wrong because taking this medication 2 hours before a meal is not required for clients taking lithium.
Lithium can be taken with or without food, but it should be taken at the same time each day to keep a steady level in the blood.
Taking lithium 2 hours before a meal may cause stomach upset, which is a common side effect of lithium.
