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.

Answer and Explanation

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 : Uric acid levels are expected to be increased in a client with acute gout. Gout is associated with hyperuricemia, where serum or plasma urate concentrations exceed 6.8 mg/dL. This elevation in uric acid can lead to the formation of monosodium urate crystals in joints, causing the characteristic painful inflammation of gout.

Choice B reason : Intrinsic factor is not related to gout. It is a protein produced by the stomach that is necessary for the absorption of vitamin B12.

Choice C reason : Chloride levels are typically not affected in acute gout and are not a specific indicator for this condition.

Choice D reason : Creatinine kinase is an enzyme found in the heart, brain, skeletal muscle, and other tissues. Elevated levels may indicate muscle damage but are not a specific marker for gout.

A. "This means your lung is fully re-expanded." B. "Your breathing pattern causes this." C. "Suction pressure that is too high causes this." D. "This indicates a possible air leak."

Correct Answer is B

Explanation

Choice A reason: The fluctuation of fluid in the water-seal chamber does not necessarily mean that the lung is fully re-expanded. The water-seal chamber's fluid level fluctuates with the client's breathing because it reflects the changes in intrathoracic pressure.

Choice B reason: The statement "Your breathing pattern causes this" is correct. The fluctuation, also known as tidaling, in the water-seal chamber is normal and occurs in response to the client's breathing. When the client inhales, negative pressure in the chest cavity causes the fluid level to rise, and when the client exhales, the pressure becomes positive, causing the fluid level to fall.

Choice C reason: Suction pressure that is too high can cause continuous bubbling in the suction control chamber but does not directly cause the fluid in the water-seal chamber to rise and fall. The suction control chamber's bubbling should be steady and gentle when the suction is set correctly.

Choice D reason: Continuous bubbling in the water-seal chamber may indicate an air leak, which is a problem that needs to be addressed. However, normal fluctuation with breathing is not indicative of an air leak.
