A client who has atrial fibrillation is prescribed warfarin therapy.
Which of the following statements by the client indicates an understanding of the medication?
“I should avoid foods that are high in vitamin K.”.
“I should take this medication with food.”.
“I should report any unusual bleeding or bruising to my provider.”.
“I should avoid taking aspirin while taking this medication.”.
The Correct Answer is A
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.

Correct Answer is ["A","B","C","E"]
Explanation
Choice A rationale:
Stopping the heparin infusion immediately is essential when the client's aPTT is significantly elevated (in this case, 120 seconds). A prolonged aPTT indicates a higher risk of bleeding, and discontinuing the heparin infusion is a crucial step in preventing further bleeding.
Choice B rationale:
Administering protamine sulfate is necessary when a client on heparin therapy experiences excessive bleeding or if the aPTT is significantly elevated. Protamine sulfate acts as a heparin antagonist and can reverse the anticoagulant effects of heparin.
Choice C rationale:
Notifying the healthcare provider of the significantly prolonged aPTT is essential because it may indicate a need for adjustments in the heparin dosage or therapy. The provider can determine the appropriate course of action based on the client's clinical condition.
Choice D rationale:
Drawing a prothrombin time (PT) and international normalized ratio (INR) level is not necessary in this situation. PT and INR are more relevant parameters when assessing clients on warfarin therapy, not heparin.
Choice E rationale:
Monitoring the client for signs and symptoms of bleeding is crucial when the aPTT is prolonged, as it indicates a higher risk of bleeding. This action allows for early detection and intervention to prevent complications.
Correct Answer is A
Explanation
A. This finding requires immediate action, as it indicates that the client is not receiving the prescribed amount of oxygen, which can compromise the oxygenation and perfusion of the tissues. The PN should adjust the flowmeter to deliver 3 liters per minute of oxygen, and check for any leaks or kinks in the tubing.
The other options are not correct because:
B. The absence of a humidifier does not require immediate action, as it is not a critical component of the oxygen delivery system. A humidifier can help moisten the dry oxygen and prevent mucosal irritation, but it is not essential for oxygenation.
CThe supine position does not require immediate action, as it is not a contraindication for oxygen therapy. The client may prefer this position for comfort or rest, and it does not affect the oxygen delivery or uptake.
D . The snug fit of the cannula does not require immediate action, as it is not a problem for oxygen therapy. The cannula should fit snugly against the client's cheeks to prevent dislodgment or slippage, and it does not interfere with the oxygen flow or diffusion.
