A nurse is preparing a client for a magnetic resonance angiography (MRA). The client is allergic to iodinated contrast dye. Which of the following actions should the nurse plan to take?
Administer prednisone before the test.
Consult with the provider to change to a CT scan.
Assess the alkaline phosphatase level.
Obtain the client's allergy history to seafood.
The Correct Answer is A
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 A
Explanation
Choice A reason: This response is appropriate because it encourages the client to seek professional medical advice, ensuring they receive personalized recommendations based on their health status and needs. It also emphasizes the importance of a physical examination to rule out any contraindications or underlying health issues before starting any contraceptive method.
Choice B reason: Storing the CPM machine on the floor when not in use is not recommended as it can pose a tripping hazard and may not comply with safety standards. The machine should be stored properly according to the manufacturer's instructions to ensure safety and maintain the equipment's integrity.
Choice C reason:While barrier methods are a good option for preventing both pregnancy and sexually transmitted infections (STIs), suggesting a specific method without a full assessment of the client's needs and preferences is not ideal. It is better to involve a healthcare provider in the decision-making process.
Choice D reason: Increasing the range of motion rapidly when the CPM machine is used intermittently is not advised. Adjustments to the range of motion should be made gradually and according to the client's tolerance and the surgeon's orders. Rapid increases can cause pain and may hinder the healing process.
Correct Answer is A
Explanation
Choice A reason: Drawing the regular insulin into the syringe first is correct. When mixing two types of insulin, the clear (regular) insulin should be drawn up before the cloudy (NPH) insulin to prevent contamination.
Choice B reason: Storing prefilled syringes with the needle pointed upward can cause air bubbles to move into the insulin, which can alter the dose when injected. The needle should be pointed downward.
Choice C reason: Shaking the NPH vial vigorously is not recommended as it can create air bubbles and affect the insulin dose. Instead, the vial should be gently rolled between the hands to mix the insulin.
Choice D reason: Inserting the needle at a 15-degree angle is incorrect for subcutaneous injections. A 90-degree angle is typically used unless the patient is very thin, in which case a 45-degree angle may be used.
