A nurse is instructing a nursing assistant on how to assist a patient with bathing.

The patient has hemiparesis on the left side due to a stroke.

Which of the following statements by the nursing assistant demonstrates understanding of the teaching?

Choice A rationale:

The client's statement, "I should avoid foods that are high in vitamin K," indicates an understanding of the medication. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-containing foods helps maintain a stable INR (International Normalized Ratio) and warfarin's effectiveness. Clients on warfarin should be educated about avoiding drastic changes in their vitamin K intake.

Choice B rationale:

Taking warfarin with food or on an empty stomach doesn't significantly impact its efficacy. Therefore, this statement is not indicative of the client's understanding of the medication.

Choice C rationale:

The statement "I should report any unusual bleeding or bruising to my provider" is important but doesn't specifically reflect an understanding of warfarin. It's a general caution for anyone taking anticoagulants.

Choice D rationale:

While it's important to avoid excessive use of medications like aspirin that can increase the risk of bleeding, this statement doesn't directly demonstrate an understanding of warfarin itself.

The correct answer is Choice B.

Choice A rationale: While notifying the charge nurse about the client’s condition is important, it is not the most critical action. The charge nurse’s role would be to coordinate care and ensure appropriate resources are available, but the immediate safety and well-being of the client and others in the facility is the priority. Therefore, this choice is not the most important action for the nurse to take.

Choice B rationale: Instituting droplet precautions, placing the client in a private room, and keeping the door closed is the most important action. COVID-19 is primarily spread through respiratory droplets when an infected person coughs, sneezes, or talks. It can also be spread by touching a surface or object that has the virus on it and then touching the mouth, nose, or eyes. Therefore, it is crucial to implement droplet precautions to prevent the spread of the virus. This includes wearing a mask, eye protection, and a gown and gloves when caring for the client. The client should also be placed in a private room with the door closed to further prevent the spread of the virus.

Choice C rationale: While it is important for the client to inform others that they may have been potentially exposed, this is not the most critical action. The priority is to prevent the spread of the virus within the healthcare facility. Once the client is appropriately isolated and precautions are in place, the client can be educated and assisted with notifying others about potential exposure.

Choice D rationale: Placing the nasal swab specimen for COVID-19 directly into a biohazard bag is a standard procedure when collecting specimens for testing. However, this action does not address the immediate need to prevent the spread of the virus within the healthcare facility. Therefore, this choice is not the most important action for the nurse to take.
