[pane00]

When providing nutritional counseling to a client at risk for kidney stones, the nurse should recommend a:
 
  1. Low-sodium diet.
   2. High-purine diet.
   3. Low-potassium diet.
   4. High-protein diet.

Question 2

In patients receiving parenteral nutrition, high blood glucose levels may be caused by
 
  a. inadequate infusions of potassium.
  b. rapid infusions of high levels of dextrose.
  c. use of peripheral rather than central pa-renteral nutrition.
  d. infusion of too much amino acid that is deaminated and converted to glucose.

Answer to Question 1

1

Rationale: A low-sodium diet is recommended because sodium and calcium compete for reabsorption at the renal tubule and excessive sodium will result in increased calcium excretion in the urine. Animal proteins, also known as purines, should be limited since metabolism results in uric acid formation. Potassium does not have a role in kidney stone formation.

Answer to Question 2

B
In patients receiving parenteral nutrition, high blood glucose levels may be caused by rapid infu-sions of high levels of dextrose. Potassium does not affect glucose tolerance. Use of peripheral versus central routes does not affect glucose tolerance (and generally less glucose is infused via the peripheral route). Excess amino acids are deaminated within cells and do not usually cause high blood glucose levels.
