Correct Answer: D

Rationale: The correct answer is D: 'I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or other medications that increase the risk of bleeding. Choices A, B, and C are correct statements that show understanding of warfarin therapy, such as the importance of avoiding foods high in vitamin K, taking medication consistently, and using a soft toothbrush to prevent gum bleeding.

Correct Answer: A

Rationale: The correct answer is to assess the oral cavity. 'Edentulous' means without teeth, so the nurse should assess the oral cavity for any issues related to oral health, dentures, or potential complications. This assessment is crucial to prevent oral health problems and ensure proper care for the patient. Assessing the room for drafts (choice B) is unrelated to the patient's edentulous status and does not address the immediate care needs. Assessing ankles for edema (choice C) is important for circulatory assessment but not directly related to the patient being edentulous. Assessing for reduced sensations (choice D) would be more relevant for neurological or sensory concerns, which are not specifically associated with being edentulous.

Correct Answer: A

Rationale: The most critical aspect for the nurse to include in the discharge plan for a client performing his own dressing changes at home following abdominal surgery is the demonstration of appropriate hand hygiene. Proper hand hygiene is essential to prevent the introduction of infection during dressing changes. While wound care technique, signs and symptoms of infection, and instructions for contacting the healthcare provider are all important components of the discharge plan, ensuring the client understands and practices proper hand hygiene is paramount to minimize the risk of infection. This choice takes precedence as it directly addresses infection prevention during the dressing changes, which is crucial for successful post-operative recovery.

Correct Answer: A

Rationale: Postural hypotension is a common sign of extracellular fluid volume deficit due to decreased blood volume, leading to a drop in blood pressure upon standing. Distended neck veins, dependent edema, and bradycardia are not typically associated with extracellular fluid volume deficit. Distended neck veins are more indicative of fluid volume overload, dependent edema is a sign of fluid retention, and bradycardia is not a common finding in extracellular fluid volume deficit.

Correct Answer: B

Rationale: To improve clients' commitment to a long-term goal of weight loss, attempting to develop their self-motivation is crucial. Self-motivation is essential for sustaining behavior changes over time. Providing a strict diet plan (choice A) may not address the root motivation needed for long-term success. While rewards (choice C) can be motivating, relying solely on external rewards may not foster the intrinsic motivation required for sustained weight loss. Encouraging group exercise (choice D) is beneficial, but without addressing individual motivation, it may not lead to long-term commitment to weight loss goals.
