A nurse is planning care for a client who has a newly implanted arteriovenous graft in the right arm. Which of the following actions should the nurse include in the plan of care?

Insert a saline lock into a site 10 cm (4 in) distal to the graft.

Instruct the client to avoid lifting the right arm for 72 hr.

Palpate the site for a thrill.

Check blood pressure in the right arm.

Answer and Explanation

The Correct Answer is C

Palpating the site for a thrill is an important action to assess the patency and function of an arteriovenous graft, which is a synthetic tube that connects an artery and a vein for hemodialysis access. A thrill is a vibration felt over the graft that indicates blood flow. The other options are incorrect because they could compromise or damage the graft.

Correct Answer is B

Explanation

A complete AV block (also called third-degree AV block) is a type of heart block in which there is no electrical communication between the atria and ventricles. This means that the atria and ventricles beat independently of each other, resulting in a slow and irregular pulse. A complete AV block can cause symptoms such as dizziness, fainting, chest pain, shortness of breath, and heart failure.

A permanent pacemaker is a device that sends electrical impulses to the heart to regulate its rhythm and prevent bradycardia (slow heart rate). A permanent pacemaker is indicated for clients with complete AV block and rates slower than 40/min or symptomatic bradycardia.

The other options are not indications for a permanent pacemaker. Vasovagal bradycardia is a temporary drop in heart rate and blood pressure caused by a stimulus that triggers the vagus nerve, such as pain, stress, or straining.

It usually resolves on its own or with simple measures, such as lying down or elevating the legs. Sinus tachycardia is a normal increase in heart rate in response to physical or emotional stress, such as exercise, fever, or anxiety. It usually does not require treatment unless it is caused by an underlying condition or causes symptoms.

Asymptomatic second-degree AV block is a type of heart block in which some of the electrical impulses from the atria are blocked from reaching the ventricles. It may not cause any symptoms or affect the overall heart rate. It may be benign or transient, or it may progress to a more serious type of heart block. It may require monitoring or medication, but not a permanent pacemaker unless it causes symptomatic bradycardia.

A. Urine output 45 mL/hr B. Potassium 5.2 mEq/L C. Capillary refill 1.5 seconds D. PaCO2 37 mm Hg

Correct Answer is B

Explanation

This indicates hyperkalemia, which is a common complication of severe burn injuries due to massive cell destruction and fluid lossfrom damaged tissues. Hyperkalemia can lead to cardiac dysrhythmias and arrest, which are signs of hypovolemic shock.
