The nurse is performing an assessment on a 7-year-old child who has the following symptoms: chronic watery eyes, sneezing, and clear nasal drainage. The nurse notes the presence of a transverse line across the bridge of the nose, dark blue shadows under the eyes, and a double crease on the lower eyelids. These findings are characteristic of:

Correct Answer: A

Rationale: The correct answer is A: allergies. The symptoms described such as chronic watery eyes, sneezing, and clear nasal drainage are classic signs of allergies. The presence of a transverse line across the bridge of the nose, dark blue shadows under the eyes, and a double crease on the lower eyelids are typical physical exam findings in children with allergic rhinitis. These signs are known as Dennie-Morgan lines, allergic shiners, and allergic crease respectively. Allergies are the most likely cause based on the symptoms and physical exam findings. Sinus infection (choice B) typically presents with purulent nasal discharge and facial pain. Nasal congestion (choice C) usually involves nasal stuffiness and may not present with the specific eye findings mentioned. An upper respiratory infection (choice D) may present with fever, cough, and nasal discharge, but the eye findings described are not characteristic of an upper respiratory infection.

Correct Answer: A

Rationale: The correct answer is A: overlies the sclera. The bulbar conjunctiva is the transparent layer that covers the white part of the eye (sclera). This layer helps protect the eye and keeps it moist. It does not cover the iris and pupil (B), as that is the cornea's role. It is not visible at the inner canthus (C), which is where the lacrimal caruncle is located. Lastly, it is not a mucous membrane lining the lids (D), as that is the role of the palpebral conjunctiva. Therefore, the correct answer is A.

Correct Answer: D

Rationale: The correct answer is D because intraocular pressure is primarily determined by the amount of aqueous humor produced and the resistance to its outflow at the angle of the anterior chamber. When there is an imbalance in the production and outflow of aqueous humor, it can lead to an increase in intraocular pressure, which can result in conditions like glaucoma. Choices A, B, and C are incorrect because they do not directly influence intraocular pressure. The thickness or bulging of the lens (A) is related to accommodation for near vision, the posterior chamber accommodating fluid (B) is not a primary factor in determining intraocular pressure, and the contraction of the ciliary body (C) affects the shape of the lens for focusing rather than intraocular pressure regulation.

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.

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.
