A nurse is assessing a client who is taking digoxin to treat chronic heart failure.
Which of the following findings should indicate to the nurse that the client is developing digoxin toxicity?
Hearing loss.
Tachycardia.
Blurred vision.
Insomnia.
The Correct Answer is C
Choice A rationale:
Hearing loss is not a typical sign of digoxin toxicity. Digoxin toxicity primarily affects the visual system, leading to disturbances such as blurred or yellow-tinted vision. It can also cause various cardiac symptoms due to its effects on heart rhythm and contractility. Hearing loss is not a recognized symptom of digoxin toxicity.
Choice B rationale:
Tachycardia (fast heart rate) can be a sign of digoxin toxicity. Digoxin can cause arrhythmias and alter heart rate, which may lead to tachycardia. While this is a possible symptom, it is not as specific as other manifestations, such as visual disturbances.
Choice C rationale:
Blurred vision is a hallmark sign of digoxin toxicity. Digoxin can cause disturbances in color vision, such as seeing yellow or green halos around objects. Blurred vision is a significant indicator of digoxin toxicity and requires prompt medical attention.
Choice D rationale:
Insomnia is not a recognized symptom of digoxin toxicity. Digoxin toxicity primarily affects the cardiovascular and visual systems, leading to symptoms related to heart rhythm disturbances and vision changes. Insomnia is not a typical manifestation of digoxin toxicity.

Correct Answer is D
Explanation
Choice A rationale:
A sore throat is a common and expected finding after a tonsillectomy due to irritation from the procedure. While it can cause discomfort, it is not a priority concern unless it worsens significantly or is accompanied by other symptoms indicating complications such as bleeding or infection.
Choice B rationale:
Frequent swallowing is expected after a tonsillectomy due to the presence of throat pain and swelling. It is not a priority concern unless it is excessive or accompanied by signs of bleeding, such as vomiting blood.
Choice C rationale:
Blood-tinged mucus is a common finding in the immediate postoperative period after a tonsillectomy. It is expected due to the healing process and is not a cause for concern unless it becomes profuse or is accompanied by active bleeding.
Choice D rationale:
Dark brown emesis is a concerning finding after a tonsillectomy. It could indicate bleeding from the surgical site or another gastrointestinal issue. Dark brown emesis suggests that the blood has been partially digested, indicating that the bleeding might be higher up in the gastrointestinal tract. This finding requires immediate medical attention as it could lead to significant blood loss and complications if not addressed promptly.
Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"E"}
Explanation
Upper gastrointestinal (GI) endoscopy: This procedure is often indicated for patients presenting with symptoms suggestive of gastrointestinal bleeding, such as dark, tarry stools (melena), which can indicate bleeding in the upper GI tract.
Dark tarry stool: This finding suggests the presence of digested blood, which typically originates from the upper GI tract. This symptom, along with a history of abdominal pain that worsens after eating, indicates a potential peptic ulcer or other upper GI pathology.
