Jaundice is manifested by a yellow skin colour, indicating rising levels of bilirubin in the blood. Which of the following findings is indicative of true jaundice?

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: The presence of tears along the inner canthus. This is a normal finding during an eye examination as tears are produced by the lacrimal gland and drain into the nasolacrimal duct, which exits at the inner canthus. This indicates proper tear production and drainage. Incorrect choices: B: A blocked nasolacrimal duct in a newborn infant - This would present as excessive tearing and discharge. C: A slight swelling over the upper lid and along the bony orbit if the patient has a cold - This could indicate inflammation due to infection. D: The absence of drainage from the puncta when the inner orbital rim is pressed - This would suggest an issue with the lacrimal drainage system.

Correct Answer: C

Rationale: The correct answer is C because the nurse should use the Snellen chart positioned 6.1 m (20 ft) away to assess visual acuity. This is the standard method for testing distance vision. The nurse should ask the patient to read the letters on the chart from the top row down, covering one eye at a time if necessary. This method provides an accurate measurement of visual acuity at a distance. A: Performing the confrontation test assesses visual fields, not visual acuity. B: Using a Jaeger card is for near vision testing, not distance visual acuity. D: Assessing the ability to read newsprint at a close distance does not provide an accurate measurement of visual acuity at a distance.

Correct Answer: D

Rationale: The correct answer is D: mandible. The temporomandibular joint is located just below the temporal artery and it connects the mandible (lower jaw) to the temporal bone. This joint allows for movement of the jaw during actions like chewing and speaking. Choices A, B, and C are incorrect because the temporomandibular joint is not located near the hyoid bone (A), the vagus nerve (B), or the tragus of the ear (C). These structures are not directly associated with the temporomandibular joint's anatomical location and function.

Correct Answer: A

Rationale: The correct answer is A because vision is not fully developed until around 2 years of age. Newborns have limited visual capabilities and their visual acuity improves over time. Choices B, C, and D are incorrect because infants do not develop the ability to focus on an object at 8 months (B), develop coordinated eye movements by 3 months (C), or have uncoordinated eye movements in the first year of life (D). These statements do not accurately reflect the timeline of visual development in infants.
