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: C

Rationale: The correct answer is C: the presence of shadows, which may indicate glaucoma. When a light is directed across the iris from the temporal side, it helps in evaluating the presence of shadows in the anterior chamber angle, which can suggest a narrow or closed angle glaucoma. This technique is known as transillumination test and is important in detecting potential glaucoma cases. A: Drainage from dacryocystitis is incorrect as it is typically assessed by pressing on the lacrimal sac area to observe for discharge. B: Conjunctivitis over the iris is incorrect as conjunctivitis is an inflammation of the conjunctiva, not the iris. D: A scattered light reflex indicative of cataracts is incorrect as cataracts cause clouding of the lens, not scattering of light across the iris.

Correct Answer: A

Rationale: The dry mucosa and deep fissures in the tongue indicate dehydration in the patient. Dehydration causes decreased saliva production, leading to dry mouth and tongue fissures. This is a common symptom of dehydration. The lack of moisture in the oral cavity can result in these physical signs. The other choices are incorrect because irritation by gastric juices typically presents with other symptoms, a normal oral condition would not show these specific findings, and side effects of nausea medication would not directly cause dry mucosa and deep fissures in the tongue. Therefore, the correct answer is A: dehydration.

Correct Answer: D

Rationale: The correct answer is D: Enlarged regional lymph nodes. In otitis externa, there may be regional lymphadenopathy due to inflammation and infection. Rhinorrhea (A) is associated with upper respiratory infections, not otitis externa. Periorbital edema (B) is seen in conditions like periorbital cellulitis. Pain over the maxillary sinuses (C) is indicative of sinusitis, not otitis externa.

Correct Answer: B

Rationale: The correct answer is B: damage to the trigeminal nerve. Trigeminal nerve damage can result in the inability to differentiate between sharp and dull sensations on the face. The trigeminal nerve is responsible for transmitting sensory information from the face to the brain. Bell's palsy (choice A) affects facial muscles, not sensory perception. Frostbite (choice C) typically causes numbness rather than loss of sensation discrimination. Scleroderma (choice D) is a connective tissue disorder that does not directly affect sensory perception on the face.
