Which of the following is true in regards to hyperopia?

Patient would be unable to pass the Snellen exam.

Difficulty seeing from far or at a distance.

Inability to see objects or letters close in range.

Patient most likely will pass the Rosenbaum chart.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Patients with hyperopia (farsightedness) are able to see distant objects clearly but may have difficulty focusing on near objects. They can pass the Snellen exam, which measures distance vision, but may struggle with close-up tasks.

Choice B rationale

Hyperopia involves difficulty seeing close objects, not distant ones. Therefore, patients with hyperopia would not have difficulty seeing from far or at a distance, making this statement incorrect.

Choice C rationale

Hyperopia, or farsightedness, is characterized by the inability to see objects or letters that are close in range. It occurs when the eye's shape causes light to focus behind the retina instead of directly on it, leading to blurred near vision. Corrective lenses can help focus light properly on the retina.

Choice D rationale

The Rosenbaum chart is used to assess near vision acuity, which would highlight issues with hyperopia. However, patients with hyperopia would pass the Snellen exam, which tests distance vision, but might struggle with the Rosenbaum chart. .

Correct Answer is A

Explanation

Choice A rationale

Vitiligo is a condition caused by the destruction or malfunction of melanocytes, the cells responsible for producing melanin pigment. This leads to the development of white patches on the skin, as melanin is absent in these areas. Vitiligo is an autoimmune condition and can affect any part of the body, including the skin, hair, and mucous membranes.

Choice B rationale

Excess apocrine glands in the feet are not related to vitiligo. Apocrine glands are sweat glands found primarily in the underarm and genital areas and are responsible for the secretion of a thick, odorless fluid. Their overactivity does not result in the white patches seen in vitiligo.

Choice C rationale

Impetigo is a bacterial skin infection characterized by red sores, blisters, and crusting. It is not related to vitiligo and does not cause depigmentation. Impetigo is treated with antibiotics, whereas vitiligo requires different management strategies to address the loss of pigment.

Choice D rationale

Vitiligo is not caused by an excess of melanin pigment. Rather, it is the result of melanin loss or the absence of melanocytes in certain areas of the skin, leading to the characteristic white patches.

A. The sides of the mouth are symmetric when the patient smiles. B. The patient's eyes move to the left, right, up, down, and obliquely during conversation. C. The patient's eyelids blink periodically. D. The patient moistens the lips with the tongue.

Correct Answer is A

Explanation

Choice A rationale

The sides of the mouth being symmetric when the patient smiles indicate intact function of the facial cranial nerve (CN VII). This nerve controls the muscles responsible for facial expressions, including smiling, frowning, and closing the eyes. Symmetry in these actions suggests that the facial nerve is functioning properly and that there is no nerve damage or weakness.

Choice B rationale

The patient's eyes moving to the left, right, up, down, and obliquely during conversation are functions of the oculomotor nerve (CN III), trochlear nerve (CN IV), and abducens nerve (CN VI), not the facial cranial nerve (CN VII). These nerves work together to control the movements of the eye muscles, enabling the eyes to move in different directions and maintain proper alignment.

Choice C rationale

Periodic blinking of the eyelids involves the oculomotor nerve (CN III) and the facial nerve (CN VII). The oculomotor nerve controls the muscles that lift the eyelid, while the facial nerve controls the muscles that close the eyelid. Blinking is a coordinated action involving both nerves, but the observation alone is not sufficient to determine the integrity of CN VII.

Choice D rationale

The patient moistening the lips with the tongue involves the function of the hypoglossal nerve (CN XII), which controls the movements of the tongue. The hypoglossal nerve is responsible for the motor control of most of the tongue muscles, allowing for actions like licking the lips, speaking, and swallowing. It is not related to the facial cranial nerve (CN VII).
