The nurse is caring for a patient who has a venous leg ulcer. The patient asks why these ulcers occur. What will the nurse explain as the cause for the development of venous ulcers?

A. Continue to administer the metoprolol tartrate as ordered:
Metoprolol is a beta-blocker commonly used to treat hypertension, angina, and heart failure. One of its main effects is to decrease heart rate and blood pressure. In this scenario, the patient's vital signs reveal a low heart rate (48 bpm) and relatively low blood pressure (100/50 mmHg). Given that metoprolol can further reduce heart rate and blood pressure, it would be prudent for the nurse to withhold the medication until further assessment is conducted.

B. Ask the patient if her pulse is within the normal range:
While it's essential to assess the patient's understanding of her condition, asking if her pulse is within the normal range is not sufficient. The nurse should perform a more thorough assessment and consider the clinical significance of the vital signs obtained. In this case, a heart rate of 48 bpm is lower than the typical normal range for adults (60-100 bpm), indicating bradycardia, which may be symptomatic or concerning in the context of administering a beta-blocker like metoprolol.

C. Hold the medication and call the provider:
Given the patient's low heart rate (bradycardia) and relatively low blood pressure, holding the metoprolol tartrate and contacting the healthcare provider is the most appropriate action. Bradycardia and hypotension can be signs of excessive beta-blockade, especially with medications like metoprolol, which can further lower heart rate and blood pressure. The nurse should notify the provider promptly to discuss the patient's condition and determine the appropriate course of action.

D. Ask the patient to eat salty foods:
Encouraging the patient to eat salty foods would not address the underlying issue of bradycardia and hypotension. While increasing salt intake may help raise blood pressure in some cases, it is not a standard intervention for managing symptomatic bradycardia or low blood pressure caused by medication effects.

A. Loss of hair over toes:
Loss of hair over the toes is not typically associated with deep vein thrombosis (DVT). Instead, it may be indicative of peripheral arterial disease (PAD) or poor peripheral circulation. In DVT, symptoms are more related to venous congestion and inflammation rather than hair loss.

B. Tenderness in the thigh:
Tenderness in the thigh is a common clinical manifestation of deep vein thrombosis (DVT). It occurs due to the presence of a thrombus within the deep veins of the thigh, causing local inflammation and irritation of the vessel wall. This tenderness may be elicited by palpation along the course of the affected vein.

C. Rest pain:
Rest pain is not typically associated with deep vein thrombosis (DVT). Rest pain is more commonly seen in conditions such as peripheral arterial disease (PAD), where inadequate blood supply to the extremities leads to ischemic pain at rest, especially during periods of reduced blood flow.

D. Auscultation of bruit over pedal pulse:
Auscultation of a bruit over the pedal pulse is not typically associated with deep vein thrombosis (DVT). A bruit is an abnormal sound caused by turbulent blood flow through a narrowed or obstructed vessel, commonly heard in arterial conditions such as atherosclerosis. In DVT, venous obstruction does not typically produce bruits.
