Which assessment finding for a patient on mitotane therapy requires nursing action?

In patients undergoing mitotane therapy, which is often used to treat conditions such as adrenal cancer, monitoring hemodynamic stability is crucial due to the potential for effects on adrenal hormone levels and blood pressure regulation. A blood pressure reading of 90/50 mm Hg when standing indicates hypotension (low blood pressure), which can be concerning, especially in the context of a patient on mitotane.

This finding suggests that the patient may be experiencing orthostatic hypotension, which is a significant drop in blood pressure upon standing. This condition can lead to dizziness, fainting, and falls, particularly in the elderly or those with comorbid conditions. Nursing action is warranted in response to this finding to ensure patient safety, which may include sitting or lying the patient down, assessing for symptoms, and possibly notifying the healthcare provider for further evaluation and intervention.

The other assessment findings, such as a sitting blood pressure of 140/90 mm Hg, a heart rate of 80 beats per minute, and a heart rate of 60 beats per minute, do not indicate immediate concern or require nursing action in the same way. They fall within acceptable limits or represent typical physiological responses that do not prompt urgent assessment or intervention.
