The nurse is preparing to administer 1 liter (1000 mL) of 0.9% NS over 2 hours intravenously to a patient experiencing shock. At what rate will the nurse set the infusion pump? Enter the number only.
The Correct Answer is ["8.3"]
Step 1: Total volume = 1000 mL (which is 1 liter)
Step 2: Total time = 2 hours. But since the infusion pump rate is typically set in mL per minute, we need to convert this to minutes. There are 60 minutes in an hour, so 2 hours is 2 × 60 = 120 minutes.
Step 3: Now we can calculate the rate. The rate is the total volume divided by the total time. So, the rate = 1000 mL ÷ 120 minutes.
Calculating the above gives us the rate at which the nurse will set the infusion pump. Let's calculate it:
Step 4: Rate = 1000 mL ÷ 120 minutes = 8.33 mL/minute.
So, the nurse will set the infusion pump at a rate of approximately 8.33 mL per minute. If rounding is required, this can be rounded to 8.3 mL per minute.

Correct Answer is A
Explanation
Choice A reason: Administering prednisone before the test may be part of a premedication protocol for clients with a history of allergic reactions to contrast media. However, this is typically done for iodinated contrast used in CT scans, not for gadolinium-based contrast agents used in MRA.
Choice B reason: Consulting with the provider to change to a CT scan would not be appropriate if the client is allergic to iodinated contrast dye, as CT scans commonly use iodinated contrast. MRA typically uses gadolinium-based contrast agents, which may be safer for clients with iodine allergies.
Choice C reason: Assessing the alkaline phosphatase level is not directly related to preparing a client with a contrast dye allergy for an MRA. Alkaline phosphatase is an enzyme measured in blood tests and is not specific to contrast media allergies.
Choice D reason: Obtaining the client's allergy history to seafood is not necessary for MRA preparation. While there is a common misconception that seafood allergies are related to iodinated contrast allergies, the evidence does not support this association.
Correct Answer is B
Explanation
Choice A reason: This statement does not indicate a need for further instruction. It is recommended to take other medications at least 30 minutes after alendronate to ensure proper absorption of the drug.
Choice B reason: This statement indicates a need for further instruction. Alendronate should be taken with plain water, not milk. The calcium in milk can interfere with the absorption of alendronate.
Choice C reason: This statement is correct and does not indicate a need for further instruction. Patients are advised to stay upright for at least 30 minutes after taking alendronate to prevent esophageal irritation or reflux.
Choice D reason: This statement is correct and does not indicate a need for further instruction. Periodic bone density tests are necessary to monitor the effectiveness of alendronate therapy in treating osteoporosis.
