A nurse is performing a focused eye assessment. Select up to 5 unexpected findings.

A) Consensual constriction present: Consensual constriction of the pupil is a normal finding when light is shined into one eye, causing both pupils to constrict simultaneously. This is a normal response and not an unexpected finding.

B) Snellen chart finding 20/40: A Snellen chart result of 20/40 indicates that the patient's vision is slightly less than normal but still within acceptable limits for daily functioning. This is not considered an unexpected or abnormal finding for an adult.

C) Sting to the upper eyelid: A sting or discomfort in the upper eyelid is an unexpected finding and may suggest irritation, infection (such as blepharitis), or trauma. This symptom should be further evaluated, as it is not typical during a normal eye assessment.

D) Pupil size 4 mm: A pupil size of 4 mm is considered normal and expected in a well-lit environment for most adults. It falls within the typical range for pupil size, so it is not an unexpected finding.

E) Jerky eye movements with the 6 Cardinal Fields of Gaze: Jerky or abnormal eye movements, such as nystagmus or inability to follow the cardinal fields of gaze smoothly, are unexpected findings. This could suggest neurological conditions, muscle weakness, or issues with the vestibular system, all of which warrant further investigation.

F) Pupil size 6 mm: A pupil size of 6 mm can be normal in low-light conditions (dilated pupils), but in a well-lit environment, it is on the larger end of the normal range. If this is observed in normal light, it may indicate a pathological condition, medication side effect, or neurological issue, but it could also be normal for some individuals. It’s less of an "unexpected" finding than jerky eye movements or a stinging sensation, but it may warrant monitoring if unusual for the patient.

G) Erythema to lower eyelid: Erythema (redness) to the lower eyelid is an unexpected finding, which could suggest an infection (such as conjunctivitis), irritation, or inflammation. This finding should be further assessed, as redness in the eyelid area is not typical during a normal eye assessment.

A) Bacterial: Bacterial infections in the mouth typically result in symptoms like foul odor, swelling, or pus, but they do not generally cause a black, hairy appearance on the tongue. A black, hairy tongue is more commonly associated with fungal overgrowth or other non-bacterial factors.

B) Fungal: A black, hairy tongue is often caused by an overgrowth of yeast or fungi, particularly Candida. This condition occurs when the normal balance of microorganisms in the mouth is disrupted, leading to the growth of fungi on the tongue’s papillae. These elongated, discolored papillae can trap food, bacteria, and dead cells, leading to a dark, furry appearance.

C) Parasite: Parasitic infections in the mouth are rare and usually cause symptoms such as sores, swelling, or difficulty swallowing, but they do not typically result in a black, hairy tongue. A parasitic infection would have a different set of symptoms and appearance.

D) Viral: Viral infections, such as those caused by the herpes simplex virus, can cause sores or ulcers in the mouth but do not typically cause a black, hairy appearance of the tongue. Viral infections might also cause symptoms like fever, pain, or swelling, but not this specific characteristic.
