The nurse educator is speaking with a community group about renal disorders. Which statement is appropriate for the educator to include regarding renal stones?

"Frequency is greater in the northern United States."

"Fluid excess is implicated in many cases of renal stones."

"Diet plays a role in the formation of some types of stones."

"Women have a greater risk overall than men."

Answer and Explanation

The Correct Answer is C

C. Dietary factors, such as high intake of certain foods (e.g., animal protein, sodium, oxalate-rich foods) and low intake of others (e.g., fluids, calcium), can influence the composition of urine and contribute to the formation of renal stones. For example, calcium oxalate stones can form when there is an imbalance of calcium and oxalate in the urine, while uric acid stones can form in individuals with high purine diets.
A. The frequency of renal stones can vary depending on factors such as climate, dietary habits, and genetic predisposition, but it is not specifically associated with the northern United States.
B. Dehydration and inadequate fluid intake can contribute to the formation of renal stones, particularly calcium-based stones. Insufficient fluid intake can lead to concentrated urine, which increases the risk of stone formation and not vice versa.
D. The risk of renal stones is equal in both men and women.

Correct Answer is B

Explanation

A. While it may have some impact on kidney function indirectly through its effects on blood pressure and heart function, urine output is not the primary parameter used to assess the effectiveness of carvedilol in a patient with a history of unstable angina.
B. Carvedilol, as a beta-blocker, helps reduce heart rate by blocking the effects of adrenaline on the heart. In unstable angina, lowering the heart rate can reduce myocardial oxygen demand, which is beneficial in managing ischemic symptoms
C. Carvedilol primarily affects heart rate and blood pressure but doesn't directly regulate heart rhythm. However, in patients with certain cardiac conditions, like heart failure or left ventricular dysfunction after a heart attack, carvedilol can sometimes help to stabilize heart rhythm indirectly by reducing stress on the heart.
D. Carvedilol is also effective in reducing blood pressure, which is beneficial in patients with unstable angina, as it decreases the workload on the heart and the oxygen demand of the myocardium. A blood pressure reading of 120/90 is within the normal range for an adult and indicates good control of blood pressure.

A. Change the IV site dressing every 48-72 hours B. Change the IV tubing every 24 hours C. Weigh the client every other day on the same scale D. Obtain the client's blood glucose every 12 hours

Correct Answer is B

Explanation

B. Changing the IV tubing every 24 hours helps prevent the accumulation of bacteria and other contaminants within the tubing, reducing the risk of infection. This practice is particularly important for clients receiving TPN, as they are at higher risk of infection due to the direct infusion of nutrients into the bloodstream.
A. It is essential to maintain the integrity of the IV site to prevent infection and ensure proper TPN delivery. Changing the IV site dressing every 24 hours helps minimize the risk of contamination and infection at the insertion site.
C. Regular monitoring of the client's weight is not necessary.
D. While monitoring blood glucose levels is important for clients at risk of hyperglycemia or hypoglycemia, the frequency of monitoring should be individualized based on the client's clinical condition and risk factors.
