In which situation would the nurse hold digoxin?
When the lab reports a digoxin level 1.2 ng/mL
When the client complains of seeing yellow-green halos
When the client is edematous
When the client is pacing and very thirsty
The Correct Answer is B
a) A digoxin level of 1.2 ng/mL is within the therapeutic range, and holding the medication based solely on the level may not be necessary.
b) Seeing yellow-green halos is a symptom of digoxin toxicity, and holding the medication is appropriate to prevent further adverse effects.
c) Edema alone may not be a contraindication for administering digoxin; the nurse would assess other factors such as heart rate and rhythm.
d) Pacing and thirst are not specific signs of digoxin toxicity, and the nurse would need to assess other symptoms and factors before deciding to hold the medication.

Explanation
a) While the negative feedback loop plays a role in the body's natural regulation of corticosteroids, it does not eliminate the potential for side effects when exogenous glucocorticoids are administered.
b) Taking the drug as prescribed does not guarantee the absence of side effects. Side effects are inherent to glucocorticoid therapy and can occur even with appropriate use.
c) Interrupting the inflammatory process does not directly inhibit side effects. The anti inflammatory action is the therapeutic effect, but it does not eliminate the potential for side effects.
d) Glucocorticoids, even those produced naturally by the body, can cause side effects, and the likelihood and severity of these side effects depend on the dose and duration of treatment. Regular monitoring and appropriate management are essential.
