Answer to Question 1

B
Phlebitis is an inflammation of the vein. Its presence in a vein being used for IV therapy may be caused by mechanical forces associated with the IV device or by chemical factors related to the composition and osmolarity of the drug solution. The key manifestation is that the symptoms are directly associated with the vein. The vein with phlebitis should not receive any additional fluids and the IV therapy is discontinued. If IV therapy needs to continue, it is restarted in a different vein.

Answer to Question 2

B
Although all of these values are abnormal, only the potassium level is dangerously out of the normal range (it is low, indicating hypokalemia; normal is 3.5 to 5 mEq/L). Abnormal potassium levels change the effectiveness of digoxin. In the case of hypokalemia, the sensitivity of the car-diac muscle membrane is increased to the effects of digoxin. This means that the risk for toxicity is greatly increased. The prescriber will probably order a digoxin level and lower the dosage of the drug.
