Answer to Question 1

ANS: A
A serum sodium level lower than 135 mEq/L is considered hyponatremia. A serum potassium level of 3.5 or 5.0 mEq/L and a serum sodium level of 140 mEq/L are considered within normal limits.

Answer to Question 2

ANS: B
Skin turgor is assessed by gently pinching the skin together over the sternum, on the forehead, or on the forearm. Elasticity is present and skin rapidly returns to a flat position in the well-hydrated patient. Exerting pressure against the shin would assess for edema. Vein distention and oral mucous membranes are indicators of hydration status but are not considered when assessing skin turgor.
