Correct Answer: C

Rationale: The correct answer is C: Two-point discrimination: The nurse gently pricks the patient's skin. Two-point discrimination assesses the ability to discern two points touched simultaneously on the skin. Fine motor coordination (Choice A) refers to the precise movements of small muscles, not related to tactile sensation. Stereognosis (Choice B) is the ability to recognize objects by touch, not equal hearing in both ears. Gross motor function (Choice D) involves the coordination of large muscle groups, not specifically related to tactile sensation testing.

Correct Answer: B

Rationale: Lanugo is the term used to describe the fine, down-like hairs found on a newborn's ears, shoulders, lower back, and/or forehead. These hairs are different from vernix, which is a waxy or cheese-like white substance covering the skin of newborns. Milia are small, white, or yellowish cysts that commonly appear on a newborn's face, while vibrissae are the thick, stiff hairs commonly found around the nose and other parts of the face.

Correct Answer: B

Rationale: The twelfth cranial nerve is the hypoglossal nerve, which controls the muscles of the tongue. The other choices are incorrect because the trochlear nerve is the fourth cranial nerve responsible for eye movement, the olfactory nerve is the first cranial nerve responsible for the sense of smell, and there are only twelve cranial nerves, so there is no thirteenth cranial nerve.

Correct Answer: A

Rationale: The correct answer is Orange juice. Orange juice enhances the absorption of an iron supplement due to its high vitamin C content. Vitamin C helps in the absorption of non-heme iron, the type of iron found in plant-based foods and iron supplements. Green beans, fortified milk, and baked potato do not have the same level of vitamin C as orange juice, making them less effective in enhancing iron absorption.

Correct Answer: D

Rationale: The post-icteric stage of viral hepatitis is accurately described as the stage where jaundice and dark urine occur due to the accumulation of bilirubin. The resolution of jaundice and normalization of urine color are seen in this stage. Choices A, B, and C are incorrect. In the prodromal stage, symptoms like fatigue and malaise appear before jaundice. The icteric stage is characterized by jaundice, not flu-like symptoms. The pre-icteric stage does not typically involve elevated urine bilirubin levels, as this occurs after the icteric stage.
