If a patient experiences nausea and vomiting after taking digoxin, what should the nurse assess for?

In the context of digoxin, nausea and vomiting can be indicative of toxicity, which may stem from a range of factors, including electrolyte imbalances that can occur as a result of vomiting. However, monitoring for dehydration is particularly important. Vomiting can lead to significant fluid loss, which could exacerbate any existing issues and affect the patient's overall health and stability.

When a patient is vomiting, there is a risk of losing not only water but also essential electrolytes, which can further complicate their condition. Assessing for dehydration involves looking for signs such as dry mucous membranes, decreased urine output, and hypotension, among other clinical indicators. Recognizing and addressing dehydration quickly helps prevent more severe complications, particularly in patients who may already be at increased risk due to their underlying conditions or medications like digoxin.

In contrast, while it's essential to be vigilant about electrolyte levels and heart rhythm changes associated with digoxin, in this scenario, the immediate priority following nausea and vomiting involves evaluating the patient's fluid status to ensure they remain stable and prevent additional complications.
