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: B

Rationale: The correct answer is B: hyphema. Hyphema is the presence of blood in the anterior chamber of the eye, which can occur due to trauma like being hit with a baseball bat. This indicates bleeding inside the eye, specifically in the space between the cornea and iris. Hypopyon (A) is the accumulation of white blood cells in the anterior chamber. Corneal abrasion (C) is a scratch on the cornea, not related to blood in the anterior chamber. Iritis (D) is inflammation of the iris, which does not necessarily involve blood in the anterior chamber.

Correct Answer: A

Rationale: The correct answer is A. Referring the patient to an ophthalmologist or optometrist is the appropriate action because the patient's inability to read the 20/100 line on the Snellen chart suggests significant visual impairment that requires professional evaluation. Options B and C are incorrect as they do not address the underlying cause of the vision issue. Option B focuses on a different method of assessment and does not provide a solution for the patient's visual acuity problem. Option C assumes the patient's vision issue can be corrected by reading glasses, which may not be the case for a 20/100 visual acuity. Option D is also incorrect as it only adjusts the testing distance and does not address the need for a comprehensive evaluation by an eye care specialist.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Bloody or clear watery drainage can indicate a basal skull fracture. 2. Basal skull fractures can cause cerebrospinal fluid leakage, leading to clear watery drainage. 3. Blood in the ear canal can suggest a temporal bone fracture. 4. Assessing for drainage helps identify potential serious head injuries. Summary: A. Incorrect. Purulent drainage indicates infection, not related to head injuries. C. Incorrect. Increased cerumen is not the priority in assessing head injuries. D. Incorrect. Foreign bodies in the canal are not the primary concern in this scenario.

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.
