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.

Answer and Explanation

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 B

Explanation

A. Incorrect. Suggesting finding alternative remedies through an online support group may not provide accurate or safe information.
B. Correct. This response acknowledges the client's interest and offers to provide guidance in selecting a safe alternative practitioner. It's important to ensure that any alternative therapies are safe and evidence-based.
C. Incorrect. While it's important to respect the client's personal beliefs, the nurse should also ensure that the chosen therapies are safe and effective.
D. Incorrect. Waiting for the provider to suggest alternative therapies may delay the client's access to safe and effective treatments.

A. Pale and a 24-hr fluid deficit of 30 mL B. Sunken fontanels and dry mucous membranes C. Temperature 38°C (100.4°F) and pulse rate 124/min D. Decreased appetite and irritability

Correct Answer is B

Explanation

A. Incorrect. A pale appearance and fluid deficit of 30 mL over 24 hours might require intervention but is not as critical as sunken fontanels and dry mucous membranes.

B. Correct. Sunken fontanels and dry mucous membranes are signs of dehydration, a potential complication of gastroenteritis. These findings should be reported to the provider for further evaluation and intervention.

C. Incorrect. A slightly elevated temperature and an increased pulse rate are common responses to infection and fever in infants.

D. Incorrect. Decreased appetite and irritability can be expected in infants with gastroenteritis and are not as concerning as signs of dehydration.
