Correct Answer: D

Rationale: The correct answer is D because cranial nerve X, also known as the vagus nerve, controls the movement of the soft palate and uvula. Asking the patient to say "ahhh" assesses the function of CN X as the soft palate and uvula should elevate symmetrically. A: Observing the patient's ability to articulate specific words does not specifically test CN X function. B: Assessing movement of the hard palate and uvula with the gag reflex primarily tests CN IX (glossopharyngeal nerve). C: Having the patient stick out the tongue and observing for tremors or pulling to one side primarily tests CN XII (hypoglossal nerve).

Correct Answer: A

Rationale: The correct answer is A: lesions that run together. Confluent lesions refer to merging or blending of individual lesions to form a larger lesion. This indicates a continuous area of involvement on the skin. Choices B, C, and D do not accurately describe confluent lesions as they refer to different patterns of lesion distribution such as annular, linear, or grouped. The key to identifying confluent lesions is the concept of merging or running together, which is best represented by choice A.

Correct Answer: C

Rationale: The correct answer is C: A thin, translucent membrane. In elderly patients, the tympanic membrane tends to become thinner and more translucent due to age-related changes. This is considered a normal finding as it is a common occurrence in older individuals. The other choices are incorrect because: A) Loss of high-tone frequency hearing is not a normal finding in an ear examination of an elderly patient, as age-related hearing loss typically affects high frequencies. B) Increased elasticity of the pinna is not a common age-related change and may indicate a different issue. D) A shiny pink tympanic membrane is not a typical finding in an elderly patient and could suggest inflammation or infection instead of a normal age-related change.

Correct Answer: B

Rationale: Step 1: Jaundice is characterized by a yellow skin color due to elevated bilirubin levels. Step 2: Yellow color extending up to the iris indicates systemic jaundice, involving the whole body. Step 3: Yellow patches throughout the sclera (Choice A) may not indicate systemic jaundice. Step 4: Skin appearing yellow under low light (Choice C) may not be specific to jaundice. Step 5: Yellow deposits on palms and soles (Choice D) are not typical signs of jaundice. Therefore, Choice B is correct as it reflects systemic jaundice, while the other choices do not fully align with the manifestation of true jaundice.

Correct Answer: A

Rationale: The correct answer is A: No sensation. When the sinus areas are normal, the patient should not feel any discomfort or pain upon palpation. This indicates that there is no inflammation or infection present. Choices B, C, and D are incorrect because feeling firm pressure, experiencing pain during palpation, or feeling pain behind the eyes would suggest abnormalities in the sinuses, such as congestion, inflammation, or infection. Therefore, the absence of any sensation is the expected response when the sinuses are normal.
