A nurse is caring for a client receiving sodium polystyrene sulfonate (Kayexalate) for the treatment of chronic renal disease. The nurse should monitor for which therapeutic effect of sodium polystyrene sulfonate (Kayexalate)?
Decreased serum sodium
Decreased serum phosphorus
Decreased urine specific gravity
Decreased serum potassium
The Correct Answer is D
A. Decreased serum sodium: Kayexalate exchanges sodium for potassium, so sodium may actually increase.
B. Decreased serum phosphorus: Kayexalate does not directly affect phosphate levels.
C. Decreased urine specific gravity: Kayexalate does not influence urine output or concentration.
D. Decreased serum potassium: Kayexalate treats hyperkalemia by exchanging potassium ions for sodium in the intestines, lowering serum potassium.

Correct Answer is C
Explanation
A. Auscultate the antecubital fossa using a Doppler stethoscope: The graft is located in the forearm, not the antecubital fossa.
B. Measure the client's blood pressure to ensure it is higher in the left arm than the right: This does not assess AV graft patency and blood pressure should be avoided in the arm with a graft.
C. Auscultate the site for a bruit: The presence of a bruit and thrill indicates blood flow through the graft, confirming patency.
D. Check the brachial and radial pulses of the left arm simultaneously: While peripheral pulses can offer some insight, they do not directly confirm graft patency.
Correct Answer is A
Explanation
A. Skin is red, blanches, and weeps: This is consistent with deep partial-thickness burns. These burns damage deeper layers but still allow capillary refill and exudate.
B. Skin has a leathery and dry: This is characteristic of full-thickness (third-degree) burns.
C. Skin is waxy in appearance: A waxy appearance suggests full-thickness burns.
D. Skin is intact, dry, and red in color: This indicates superficial (first-degree) burns like sunburn.
