Answer to Question 1
ANS: D
The patient has a history of cardiac problems and is receiving a critical care medication, IV heparin. In this case, contacting the patient's health care provider would be appropriate to avoid harm. Increasing the infusion rate might place the patient into fluid overload and might infuse too much heparin in a short time. Reducing the infusion rate to TKO or discontinuing the solution would put the schedule even further behind.
Answer to Question 2
ANS: D
The safest action is to maintain the ordered rate. The health care provider should be consulted if the patient has not received critical IV replacement therapy. Increasing an IV rate without a health care provider's order can be detrimental for patients who have cardiac, renal, or circulatory impairment. Normal aging process results in decreased cardiac, renal, and circulatory function. The rate ordered is the one the provider intended for the administration of fluids; changing it to fit the prevailing situation is not appropriate. The bolus technique should only be used for the administration of medications or fluid challenges in patients who need a volume of IV fluid quickly. The flow rate must be consistent with the provider's order.
