The nurse is caring for a client newly diagnosed with hypertension and requires medication therapy. Which of the following medications below is considered a first line treatment for hypertension?

A) Carvedilol: While carvedilol is a beta-blocker that can be used to treat hypertension, it is not considered a first-line treatment. Beta-blockers are typically used when other first-line agents are not effective or in specific situations such as heart failure or ischemic heart disease. B) Lisinopril: Lisinopril is an ACE inhibitor and is considered a first-line treatment for hypertension. It effectively reduces blood pressure by inhibiting the angiotensin-converting enzyme, leading to vasodilation and decreased blood volume. Its well-documented efficacy and favorable side effect profile make it a common choice for initial therapy. C) Clonidine: Clonidine is an alpha-2 adrenergic agonist that can lower blood pressure but is generally not used as a first-line treatment due to its side effects and potential for rebound hypertension if discontinued abruptly. D) Doxazosin: Doxazosin is an alpha-1 blocker that can be used to treat hypertension but is not typically a first-line choice. It may be used in specific cases, such as in patients with benign prostatic hyperplasia, but other classes of medications are usually preferred for initial hypertension treatment.
