Final answer:
ACE inhibitors and ARBs are kidney protective medications, but they should be used with caution as they can affect potassium levels in the blood.
Step-by-step explanation:
ACE inhibitors and ARBs are medications commonly used to treat certain conditions such as high blood pressure and heart failure. These medications are known to be kidney protective, meaning that they help protect the kidneys from damage. However, it is important to monitor potassium (K+) levels when using ACE inhibitors and ARBs, as they can sometimes cause an increase in potassium levels in the blood, a condition called hyperkalemia.
