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 B
Explanation
Choice A reason: Changing the ostomy pouch daily is not typically necessary. Most pouches can be worn comfortably for several days before needing to be changed. Frequent changes are not only unnecessary but can also irritate the skin around the stoma.
Choice B reason: Emptying the ostomy pouch when it is 2/3 full is recommended to prevent leaks and overfilling, which can lead to discomfort and potential skin irritation. It is important to monitor the fullness of the pouch and empty it regularly to maintain hygiene and comfort.
Choice C reason: Trimming the opening of the ostomy seal to be 1/2 inch wider than the stoma is incorrect. The opening should be cut to match the size of the stoma to ensure a snug fit that prevents leakage and protects the skin around the stoma.
Choice D reason: Applying lotion to the peristomal skin when changing the ostomy pouch is not advised. Lotions or creams can interfere with the adhesive of the ostomy appliance and should be avoided. The peristomal skin should be clean and dry to ensure proper adhesion of the ostomy appliance.
Correct Answer is A
Explanation
Choice A reason: Checking the pulse distal to the graft is essential to ensure that the graft is patent and that there is adequate blood flow to the distal extremity. A palpable pulse indicates that the graft is functioning properly and not occluded. The absence of a pulse could signify a serious complication, such as thrombosis or stenosis, which requires immediate attention.
Choice B reason: Keeping the left forearm below the level of the heart is not recommended as it can increase venous pressure and swelling, potentially compromising graft function. The extremity should be kept at or above heart level to promote venous return and reduce the risk of edema.
Choice C reason: Collecting blood specimens from the graft is generally avoided to prevent damage to the graft. Blood draws can be performed from other sites to protect the integrity of the graft.
Choice D reason: Splinting the left forearm is not a standard postoperative care measure for an arteriovenous graft. While protecting the graft from injury is important, immobilization with a splint is not necessary and can impede mobility and circulation.
