The nurse assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?

A. Skin elasticity:
Assessing skin elasticity is a measure of hydration status. Improved skin turgor may suggest that the client is responding positively to diuretic therapy by eliminating excess fluid. However, this may not be as immediate or specific as other indicators of response.

B. Urinary output:
Monitoring urinary output is crucial when administering diuretics like furosemide. Increased urine output indicates that the diuretic is promoting the elimination of excess fluid from the body, which is a desired effect in managing heart failure and fluid overload.

C. Oxygen saturation:
Assessing oxygen saturation is important in monitoring respiratory status. Improvement in oxygen saturation levels indicates that the client is responding to interventions aimed at relieving respiratory distress, such as the administration of furosemide.

D. Lung sounds:
Monitoring lung sounds is a key aspect of assessing respiratory function. Reduction in wheezes and crackles suggests that the diuretic is helping to alleviate pulmonary congestion and fluid accumulation in the lungs, contributing to improved respiratory function.

E. Pain scale:
Assessing pain is relevant if the client has reported chest pain or discomfort associated with heart failure. Reduction in pain may indicate improved cardiac function and response to treatment. However, it's important to note that pain assessment may not be as specific to the effects of furosemide as other respiratory and fluid status indicators.

A. Eat a diet high in carotene:
While a healthy diet is important for overall well-being, there is no evidence to suggest that a diet high in carotene specifically prevents or treats glaucoma. The focus in glaucoma management is on intraocular pressure control.

B. Wear prescription glasses:
Prescription glasses may be beneficial for addressing refractive errors, but they do not specifically address the management of glaucoma. The client's concern about driving through a tunnel is more likely related to changes in peripheral vision associated with glaucoma.

C. Avoid frequent eye pressure measurements:
This is not the most important instruction. Monitoring intraocular pressure is a crucial aspect of glaucoma management, and the frequency of measurements is determined by the healthcare provider. Regular monitoring helps assess the effectiveness of treatment and disease progression.

D. Maintain the prescribed eye drop regimen:
This is the correct answer. The most important instruction for the client is to adhere to the prescribed eye drop regimen. Medications, often in the form of eye drops, are commonly used to lower intraocular pressure and manage glaucoma. Consistent use of prescribed medications is critical for controlling the condition and preventing further vision loss.
