Correct Answer: C

Rationale: In this situation, the nurse's priority is to determine if the client is experiencing psychotic thinking as it addresses the immediate safety concern. Psychotic thinking may pose a risk to the client's safety or the safety of others. Referring the client to a mental health counselor (choice A) may be appropriate but not the priority when safety is a concern. Encouraging the client to express their feelings (choice B) and asking about their social support system (choice D) are essential aspects of care but are secondary to addressing immediate safety issues.

Correct Answer: D

Rationale: Correct Answer: Green leafy vegetables - Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin. Tomatoes, apples, and broccoli are not contraindicated with warfarin therapy. While they are healthy choices, they do not have a significant impact on warfarin's effectiveness.

Correct Answer: A

Rationale: To maintain the sterility of the field, the nurse should place the cap from the solution sterile side up on a clean surface. This action helps prevent contamination. Choice B is incorrect because opening the outermost flap toward the body increases the risk of introducing contaminants onto the sterile field. Choice C is incorrect as the sterile dressing should be placed at least 2.5 cm (1 in) from the edge of the sterile field to prevent accidental contamination. Choice D is incorrect because setting up the sterile field above waist level could lead to inadvertent contact and compromise the field's sterility.

Correct Answer: B

Rationale: Increased appetite may indicate that the client is experiencing symptoms of hyperthyroidism due to an excessive dose of levothyroxine. This finding suggests a need for a dosage adjustment to prevent potential complications. Tremors are more commonly associated with hyperthyroidism, not necessarily indicating a need for dosage adjustment. Bradycardia and diarrhea are not typical signs of an incorrect levothyroxine dosage and would not directly warrant a need for adjustment.

Correct Answer: B

Rationale: The correct answer is to ensure the client consumes adequate protein. Protein is essential for wound healing as it supports tissue repair. Applying heat to the surgical site (choice A) is not recommended as it can increase inflammation. Although ambulation (choice C) is beneficial for circulation and preventing complications, it is not directly related to promoting wound healing. Instructing the client to drink 4 liters of water daily (choice D) is excessive and not specifically related to wound healing in this context.
