Final answer:
A client with heart failure on Enalapril, an ACE inhibitor, should monitor for a persistent dry cough and decreased blood pressure, as these are common side effects of the medication. Blood pressure tends to decrease because the drug blocks the conversion of angiotensin I to the potent vasoconstrictor angiotensin II.
Step-by-step explanation:
A client with heart failure taking Enalapril, which is one of the angiotensin-converting enzyme (ACE inhibitors), should monitor particularly for adverse effects such as C. Persistent dry cough and decreased blood pressure. These are known side effects of ACE inhibitors because these medications inhibit the enzyme that converts angiotensin I to angiotensin II, a potent vasoconstrictor which otherwise would raise blood pressure. Therefore, with its action blocked, blood pressure typically decreases. Additionally, a dry cough is a common side effect, thought to be related to the increase of bradykinin levels in the lungs which occurs when ACE is inhibited. Other potential adverse effects that might be seen with ACE inhibitors include weakness, fatigue, hyperkalemia, and in severe cases, kidney failure. It is crucial for individuals on this medication to monitor their blood pressure regularly and report any persistent side effects to their healthcare provider.
