Answer to Question 1

Answer: C, E

In order to exhibit cyanosis, the client's blood must contain about 5 g or more of unoxygenated hemoglobin per 100 mL of blood and the surface blood capillaries must be dilated. Severe anemia will interfere with the development of cyanosis, so the nurse should review the hemoglobin and hematocrit. Blood sugar, cardiac enzymes, and serum electrolytes are not implicated in this phenomenon.

Answer to Question 2

Answer: C

The client on Lasix (furosemide) may lose excess potassium, disposing the client toward metabolic alkalosis. The client is taught to refrain from the use of sodium antacids when prone to metabolic alkalosis. The client should consult with the primary care provider for gastric distress rather than self-medicate. The client who is prone to metabolic alkalosis is likely to have fluid deficits and would not be instructed to restrict fluids.
