During an examination of a 3-year-old child, the nurse notes a bruit over the left temporal area. What should the nurse do?

Correct Answer: D

Rationale: The correct answer is D because a bruit in a 3-year-old child, especially over the temporal area, is not a normal finding and could indicate a serious underlying issue such as an arteriovenous malformation or other vascular abnormality. Stopping the examination and notifying the physician is crucial for further evaluation and management. A: Continuing the examination is not appropriate as the bruit should prompt further investigation. B: Checking again in 1 hour is unnecessary delay in addressing a potentially serious issue. C: Notifying the parents alone without medical intervention may delay necessary evaluation and treatment.

Correct Answer: A

Rationale: Visual accommodation refers to the ability of the eye to adjust focus when shifting gaze between objects at different distances. The correct answer is A, pupillary constriction when looking at a near object, as this is a key component of visual accommodation. When looking at a near object, the eye needs to adjust its focus by constricting the pupil to allow more depth of field and clearer vision. This process helps in bringing near objects into focus. Choices B, C, and D are incorrect: B: Pupillary dilation when looking at a far object is not related to visual accommodation, as the pupil dilates in low light conditions to allow more light to enter the eye. C: Changes in peripheral vision in response to light is not related to visual accommodation, as peripheral vision refers to the ability to see objects outside the direct line of sight. D: Involuntary blinking in the presence of bright light is a protective reflex to shield the eyes from excessive light and is not directly related to visual

Correct Answer: B

Rationale: The correct answer is B: A dark retinal background. This is because individuals of African descent typically have a higher concentration of melanin in their eyes, resulting in a darker retinal background. This can affect the appearance of the fundus during eye examinations. Incorrect choices: A: Increased night vision - Night vision is not directly influenced by melanin levels in the eyes and is more related to the function of rods and cones in the retina. C: Increased photosensitivity - Melanin provides some protection against UV light, so individuals with darker retinas may have lower photosensitivity. D: Narrowed palpebral fissures - Palpebral fissures refer to the opening between the eyelids and are not typically influenced by melanin levels in the eyes.

Correct Answer: A

Rationale: The correct answer is A. Referring the patient to an ophthalmologist or optometrist is the appropriate action because the patient's inability to read the 20/100 line on the Snellen chart suggests significant visual impairment that requires professional evaluation. Options B and C are incorrect as they do not address the underlying cause of the vision issue. Option B focuses on a different method of assessment and does not provide a solution for the patient's visual acuity problem. Option C assumes the patient's vision issue can be corrected by reading glasses, which may not be the case for a 20/100 visual acuity. Option D is also incorrect as it only adjusts the testing distance and does not address the need for a comprehensive evaluation by an eye care specialist.

Correct Answer: B

Rationale: The correct answer is B because people of African descent commonly have a pigmented layer near the outer canthus of the lower lid called the "plica semilunaris." This is a normal anatomical variation in this population. Yellow fatty deposits over the cornea (choice A) are not typical findings in this demographic. Yellow color of the sclera extending up to the iris (choice C) is not a characteristic feature. The presence of small brown macules on the sclera (choice D) is also not a common finding in individuals of African descent.
