What should the nurse monitor for in a client receiving an ACE inhibitor?

Monitoring is essential for clients receiving ACE inhibitors due to their effects on various biochemical pathways and bodily functions. The correct answer encompasses all the listed parameters, as they are all crucial to assess in this context.

Firstly, monitoring creatinine levels is important because ACE inhibitors can alter kidney function. They can reduce glomerular filtration rate (GFR) by blocking the angiotensin II-mediated constriction of the efferent arterioles in the kidneys. An increase in creatinine levels may indicate that the kidneys are not functioning adequately, necessitating further evaluation of renal status.

Secondly, potassium levels need careful monitoring as ACE inhibitors can lead to hyperkalemia, which is an elevated level of potassium in the blood. This occurs because these medications inhibit the aldosterone secretion that promotes potassium excretion. Hyperkalemia can cause serious cardiac issues, making it crucial to keep potassium levels within a safe range during treatment.

Lastly, monitoring blood sugar levels can also be relevant for some patients, particularly those with diabetes, as there may be an interaction with glucose metabolism. Though it is not the primary focus compared to creatinine and potassium, it remains a pertinent aspect, especially in a comprehensive care plan.

Thus, the need to monitor creatinine, potassium, and possibly
