Which of the following signs indicates to the nurse that digoxin (Lanoxin) has been effective for a patient?

Correct Answer: C

Rationale: Digoxin is a medication commonly used to treat heart failure and certain types of irregular heart rhythms. One of the therapeutic effects of digoxin is an improvement in cardiac output, leading to better tissue perfusion. As the heart's pumping ability improves, blood flow to the kidneys also increases, resulting in an increase in urine output. Therefore, an increase in urine output is a positive indication that digoxin is effective for the patient. Monitoring urine output can be a valuable way for nurses to assess the response to digoxin therapy and the overall cardiac function of the patient.

Correct Answer: A

Rationale: The client's symptoms of dizziness upon standing up, along with nosebleeds and blurred vision, are suggestive of postural hypotension. Postural hypotension, also known as orthostatic hypotension, is a drop in blood pressure that occurs when a person stands up from a sitting or lying position. This drop in blood pressure can lead to symptoms such as dizziness, lightheadedness, blurred vision, and in some cases, nosebleeds. It is more common in older adults, like the 78-year-old male client in this scenario. Therefore, the nurse should assess for postural hypotension in this client to manage his symptoms and prevent complications.

Correct Answer: C

Rationale: The nurse should teach an older client with a transient ischemic attack (TIA) to comply with the medication regimen. TIA is a warning sign of a potential stroke, and medication compliance is crucial in reducing the risk of a future stroke. Medications prescribed after a TIA may include blood thinners, antiplatelet agents, antihypertensives, and cholesterol-lowering drugs. It is essential for the client to take these medications as directed by their healthcare provider to prevent further cardiovascular events. Compliance with the medication regimen plays a significant role in managing the risk factors associated with stroke and promoting long-term health and well-being.

Correct Answer: A

Rationale: The sympathetic nervous system is responsible for the body's "fight or flight" response. Tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation during times of stress or danger. These physiological responses prepare the body for action, such as running away from a threat.
