A patient is taking fludrocortisone for adrenal insufficiency. What is a vital aspect of care the nurse must monitor?

Monitoring blood pressure is a vital aspect of care for a patient taking fludrocortisone, as this medication is a synthetic mineralocorticoid that functions primarily to enhance sodium retention in the kidneys. As the sodium levels increase, the body retains more water, which can lead to an increase in blood volume and consequently elevate blood pressure.

Patients on fludrocortisone are at risk of developing hypertension due to this effect. Regularly checking blood pressure helps the nurse assess the patient's response to treatment, ensuring that blood pressure remains within a safe and acceptable range. If hypertension is detected, adjustments to the treatment regimen or additional interventions may be necessary to mitigate this side effect.

While monitoring calcium levels, heart rate, and renal function are also important in overall patient care, blood pressure is particularly critical in the context of fludrocortisone therapy due to its specific influence on fluid and electrolyte balance, which directly impacts cardiovascular health.
