A patient with a history of atrial fibrillation has contacted the clinic saying that she has accidentally overdosed on her prescribed warfarin (Coumadin). The nurse should recognize the possible need for what antidote?

Factor VIII

Vitamin K

IVIG

Factor X

Answer and Explanation

The Correct Answer is B

A. Factor VIII: Factor VIII is a component of the clotting cascade, but it is not the antidote for warfarin. Factor VIII is used in the treatment of hemophilia A.

B. Vitamin K: This is the correct answer. Vitamin K is the antidote for warfarin overdose. It helps in the synthesis of clotting factors.

C. IVIG (Intravenous Immunoglobulin): IVIG is not an antidote for warfarin. It is used for various immune-related conditions.

D. Factor X: Factor X is also a clotting factor, but it is not the antidote for warfarin. Factor Xa inhibitors are used as anticoagulants.

Correct Answer is A

Explanation

A. "The test will provide a detailed profile of the heart’s electrical activity."

This statement is inappropriate because transesophageal echocardiography (TEE) primarily provides detailed images of the heart's structure, such as the valves and chambers, rather than focusing on the heart's electrical activity. The assessment of electrical activity is typically associated with electrocardiography (ECG or EKG) rather than echocardiography.

B. "I will need to start an IV in your arm before the test."

This statement is appropriate. It is common for medical procedures, including TEE, to require an intravenous (IV) line for administration of medications or fluids during or after the procedure.

C. "Your throat may be a little sore after the exam."

This statement is appropriate. TEE involves inserting a probe through the esophagus, and it is common for patients to experience a sore throat afterward due to the presence of the probe.

D. "You will need to refrain from eating and drinking 6-8 hours before this test."

This statement is appropriate. It is standard practice to ask patients to fast for a specific period before TEE to minimize the risk of complications, such as aspiration, during the procedure.

A. Frequent change of position B. Antibiotics C. Oxygen humidification D. Chest physiotherapy

Correct Answer is A

Explanation

A. Frequent change of position:

Frequent changes in position help prevent pooling of secretions and promote lung expansion. This simple and cost-effective measure is important in preventing complications related to immobility, such as pneumonia and atelectasis. It aids in maintaining optimal respiratory function.

B. Antibiotics: Antibiotics are used to treat bacterial infections and would not directly address the risks associated with decreased mobility.

C. Oxygen humidification: While oxygen therapy may be necessary in some cases, humidification is typically used to prevent drying of mucous membranes and is not a primary intervention for preventing complications of decreased mobility.

D. Chest physiotherapy: Chest physiotherapy involves techniques to mobilize respiratory secretions and may be indicated in specific situations. However, it is not as simple and cost-effective as frequent changes in position.
