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 D

Explanation

A. Incorrect. This client is immobile but not at immediate risk from fire.
B. Incorrect. While a bedridden client wearing a hearing aid requires assistance, they are not in immediate danger like a client in traction.
C. Incorrect. A client using a wheelchair and being confused requires assistance, but the urgency is not as high as with a client in traction.
D. Correct. Oxygen is a highly combustible gas, and any spark or open flame near an oxygen source can ignite a fire. Therefore, clients receiving oxygen are at the highest risk during a fire.

A. The client's heart rate increases by 10/min. B. The client's diastolic blood pressure increases by 10 mm Hg. C. The client reports heart palpitations. D. The client's systolic blood pressure decreases by 25 mm Hg.

Correct Answer is D

Explanation

Choice A rationale:

An increase in heart rate by 10 beats per minute when moving from a supine to a sitting position is a normal physiological response to compensate for decreased venous return and maintain cardiac output. This response does not indicate orthostatic hypotension.

Choice B rationale:

An increase in diastolic blood pressure by 10 mm Hg when moving from a supine to a sitting position is a normal response to compensate for the effects of gravity on blood flow. It helps maintain perfusion to vital organs and does not indicate orthostatic hypotension.

Choice C rationale:

Heart palpitations can occur due to various reasons, including anxiety or arrhythmias, but they are not specific signs of orthostatic hypotension. This symptom alone does not confirm the presence of orthostatic hypotension.

Choice D rationale:

A decrease in systolic blood pressure by 25 mm Hg or more when moving from a supine to a sitting position indicates orthostatic hypotension. Orthostatic hypotension is defined as a drop in systolic blood pressure of 20 mm Hg or more or a drop in diastolic blood pressure of 10 mm Hg or more within 3 minutes of standing up. This condition can cause dizziness, lightheadedness, or fainting and can be a side effect of antihypertensive medications or other underlying medical conditions.
