Shellen chart 20/200,

Correct Answer: B

Rationale: The Shellen chart is used to measure visual acuity. The notation "20/200" means that at 20 feet, the patient can see what a normal person can see at 200 feet. Therefore, choice B is correct because 200 represents the distance at which a normal person can read the same line of letters on the chart as the patient can at 20 feet. Choices A, C, and D are incorrect as they do not accurately interpret the notation or the purpose of the Shellen chart.

Correct Answer: B

Rationale: The correct answer is B: Rectal temperature on an infant. This method provides the most accurate measurement as it reflects the core body temperature. Infants are more prone to temperature fluctuations, making rectal temperature the most reliable. Oral temperature may not be accurate due to infants' inability to keep the thermometer in their mouth. Axillary temperature (option C) is less accurate than rectal temperature. Tympanic temperature (option D) can also be influenced by factors like earwax and positioning, making it less reliable for infants.
