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","C","E"]
Explanation
Choice A rationale:
Including the family in the discharge teaching is essential, especially when dealing with a client who has communication barriers such as hearing loss and illiteracy. Involving the daughter in the teaching process ensures that she is aware of the client's care needs and can provide support at home.
Choice B rationale:
Encouraging the client to attend reading classes is not a practical intervention for an older adult with hearing loss. Reading classes may not address the immediate communication needs of the client, and the client's primary caregiver, in this case, is the daughter who will provide daily care and support.
Choice C rationale:
Facing the client when speaking is a crucial intervention when dealing with someone who has hearing loss. By facing the client, the nurse ensures that the client can see their lips and facial expressions, which can aid in lip-reading and understanding the communication better.
Choice D rationale:
Speaking loudly when teaching is not always the best approach for clients with hearing loss. While it may seem intuitive to speak loudly, it can distort speech and make it more challenging for the client to understand. Clear and slow speech, along with visual cues, is often more effective.
Choice E rationale:
Providing the daughter with written instructions is essential, especially when the client has limited reading skills. Written instructions can serve as a reference guide for the daughter, helping her provide care and support to her father accurately.
Correct Answer is ["A","C","F"]
Explanation
Choice A rationale:
Urticaria is a skin condition characterized by the sudden appearance of raised, itchy, and red welts on the skin. It is an objective finding because it can be observed and assessed visually. The presence of urticaria may indicate an allergic reaction or another underlying condition.
Choice B rationale:
Hypertension is a subjective finding because it cannot be directly observed. It requires blood pressure measurement to confirm, making it a subjective parameter.
Choice C rationale:
Diaphoresis refers to excessive sweating, which can be observed and assessed visually. It is an objective finding and may be indicative of various conditions, including anxiety or fever.
Choice D rationale:
Nausea is a subjective symptom because it is a sensation that the client experiences and reports. It cannot be directly observed by the nurse, making it a subjective parameter.
Choice E rationale:
Anxiety is a subjective symptom, as it is a mental and emotional state experienced by the client. It cannot be directly observed, making it a subjective parameter.
Choice F rationale:
Edema is an objective finding because it can be visually assessed by the nurse. Edema is the accumulation of excess fluid in body tissues, and its presence or absence can be objectively determined.
