Correct Answer: C

Rationale: The correct answer is C because purpura is characterized by the presence of confluent and extensive patches of petechiae and ecchymoses. Petechiae are small, pinpoint hemorrhages less than 2mm in size, and ecchymoses are larger bruises. This presentation is indicative of a more severe underlying condition, such as a bleeding disorder or vasculitis. Choice A is incorrect as it describes spider veins or telangiectasias, not purpura. Choice B describes a birthmark, not purpura. Choice D is incorrect as it describes petechiae, not purpura, which involves larger areas of bleeding.

Correct Answer: D

Rationale: The correct answer is D: convergence of the axes of the eyes. During the accommodation response, the eyes converge to focus on a near object. This is necessary to maintain clear vision when looking at close objects. Dilation of the pupils (A) is not part of the accommodation response. A consensual light reflex (B) refers to both pupils constricting simultaneously in response to light, not specific to accommodation. Conjugate movement of the eyes (C) refers to both eyes moving together in the same direction, which is not the primary action during accommodation.

Correct Answer: D

Rationale: The correct answer is D because a loss of air conduction, known as conductive hearing loss, refers to a problem conducting sound waves through the outer or middle ear. This type of hearing loss can be caused by issues such as earwax buildup, fluid in the middle ear, or problems with the ear canal or eardrum. Choices A, B, and C are incorrect because air conduction is not the most efficient pathway for hearing (choice A), it is not caused by vibrations of bones in the skull (choice B), and the pitch of sound is determined by the frequency, not the amplitude (choice C). Conductive hearing loss specifically relates to the transmission of sound through the outer and middle ear structures, making choice D the correct statement.

Correct Answer: B

Rationale: The correct answer is B because the patient's symptoms (change in mole size, color changes, itching, burning, bleeding) are concerning for melanoma, a type of skin cancer. Given her history of blistering sunburns, early evaluation and referral are crucial for timely intervention. Option A is incorrect as it delays necessary evaluation. Option C is irrelevant as the symptoms suggest a serious condition, not environmental irritants. Option D is incorrect as compound nevi typically do not present with the described symptoms and are not common in this age group.

Correct Answer: A

Rationale: The correct answer is A because one pinch of smokeless tobacco (SLT) in the mouth for 30 minutes can indeed deliver a similar amount of nicotine as smoking one cigarette. This is because the nicotine in SLT is absorbed through the oral mucosa directly into the bloodstream, providing a quick effect. This statement is accurate and reflects the pharmacokinetics of SLT use. Option B is incorrect because smoking carries a higher risk of oral cancer compared to SLT use. Option C is incorrect as pain is not always an early sign of oral cancer, and other symptoms such as non-healing sores or lumps may indicate oral cancer. Option D is incorrect as pain can sometimes be an early sign of oral cancer, especially in advanced stages.
