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?

Choice A reason: While it is generally advised to avoid taking blood pressure readings from an arm with a PICC line to prevent complications, if the right arm cannot be used, as may be the case with the other clients listed, the nurse may have to use the left arm with extreme caution, ensuring not to disrupt the PICC line.

Choice B reason: Bell's palsy affects facial nerves and does not typically impact the measurement of blood pressure. Therefore, there is no contraindication to using the left arm for a blood pressure reading in a client with left-sided Bell's palsy.

Choice C reason: A client with right-sided weakness due to Parkinson's disease can have their blood pressure taken on the left side if the right side is too weak to provide an accurate reading or if using the right side would cause discomfort to the client.

Choice D reason: For a client with a right upper extremity arteriovenous fistula, typically created for dialysis access, blood pressure measurements should not be taken on that arm to avoid damaging the fistula. Therefore, the left arm should be used for blood pressure readings in this case.

Choice A reason: Dry areas around the pins can be a normal finding if the pin sites are healing properly. It indicates that there is no excessive moisture that could promote bacterial growth and infection. However, the nurse should continue to monitor for any signs of redness, swelling, or pain that could indicate a developing infection.

Choice B reason: Crusts around the pins are typically a sign of dried exudate, which can be part of the normal healing process. The crusts should be monitored and cleaned according to the healthcare facility's protocol to prevent infection. If the crusts are accompanied by other signs of infection, such as redness, warmth, or purulent drainage, they should be reported to the healthcare provider.

Choice C reason: Purulent drainage around the pins is a sign of infection and should be reported immediately to the unit care coordinator. Infections at pin sites can lead to complications such as osteomyelitis, delayed healing, or even systemic infection. Prompt intervention with appropriate cleaning and possibly antibiotics is necessary to prevent further complications.

Choice D reason: The absence of pain at the site can be a normal finding and is not typically a cause for concern unless there is an expectation of pain based on the patient's condition or recent procedures. However, a complete lack of sensation could indicate nerve damage or other issues, so the nurse should assess for other signs of neurovascular compromise and report any concerns to the healthcare provider.
