Which vein(s) is(are) responsible for most of the venous return in the arm?

Correct Answer: D

Rationale: The correct answer is D: Superficial. The superficial veins, like the basilic and cephalic veins, are responsible for most of the venous return in the arm due to their larger size and proximity to the surface. These veins run parallel to major arteries, assisting in venous return through the pumping action of nearby muscles. Deep veins are important but less significant in venous return compared to superficial veins in the arm. Ulnar and subclavian veins are not primarily responsible for venous return in the arm.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Inquiring about the number of sexual partners in the last 6 months is not appropriate as it can be seen as judgmental and might make the patient uncomfortable. 2. The focus should be on gathering relevant information about the patient's sexual practices and behaviors without passing judgment. 3. Questions A, B, and C are relevant and appropriate for eliciting information about the patient's sexual history without making assumptions or causing discomfort. 4. Asking about sexual activity, types of partners, and recent intimate physical contact are essential in assessing the risk factors and providing appropriate care.

Correct Answer: D

Rationale: The correct answer is D: Do a skin biopsy in the office. This is the most appropriate action to take in this scenario as the presence of multiple small, blood-red, raised lesions without pain or bleeding warrants further investigation to determine the underlying cause. A skin biopsy would provide histological information about the nature of the lesions, helping to differentiate between various skin conditions such as angiomas, petechiae or purpura. This would guide the appropriate management and rule out any serious underlying conditions. Choice A (Reassure him that there is nothing to worry about) is incorrect as the appearance of these lesions warrants further investigation rather than immediate reassurance. Choice B (Do laboratory work to check for platelet problems) is not the most appropriate initial step without first obtaining more specific information about the nature of the lesions. Choice C (Obtain an extensive history regarding blood problems and bleeding disorders) may be necessary later but is not the initial step in this case.

Correct Answer: A

Rationale: The correct answer is A: Equal status seating. This is important during an interview to create a comfortable and balanced environment for both parties. It promotes open communication and mutual respect. B: Leading questions are not ideal as they can influence the interviewee's responses and lead to biased information. C: Passive listening is ineffective as it shows disinterest and lack of engagement in the conversation, hindering effective communication. D: Distancing can create a sense of physical and emotional separation, making it difficult to establish rapport and connection during the interview.

Correct Answer: B

Rationale: The correct answer is B: Connects the second metatarsal head to the first cuneiform. The Lisfranc ligament plays a crucial role in maintaining the stability of the midfoot by connecting the second metatarsal to the first cuneiform bone. This connection is essential in weight-bearing activities to prevent excessive movement and maintain proper alignment of the bones in the midfoot. The other choices are incorrect because: A) The distal tibia is not connected to the talus by the Lisfranc ligament, C) The preservation of the medial longitudinal arch is primarily achieved by other ligaments in the foot, and D) The primary ankle stabilizer is the deltoid ligament on the medial side of the ankle, not the Lisfranc ligament.
