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 D

Explanation

Choice A rationale

While the upper outer quadrant can be prone to injury and calcifications, this is not the primary reason for its importance in breast examinations. Calcifications can occur in various parts of the breast and are often detected through mammography rather than physical examination.

Choice B rationale

Suspensory ligaments, also known as Cooper's ligaments, provide structural support to the breast. They attach to the skin and the underlying pectoral fascia. However, these ligaments are distributed throughout the breast and are not confined to the upper outer quadrant.

Choice C rationale

The upper outer quadrant is not the largest quadrant of the breast. All quadrants have relatively similar sizes. Therefore, the size of the quadrant is not the reason for its importance in breast examinations.

Choice D rationale

The upper outer quadrant of the breast is the most common location for breast tumors. This is because a significant portion of the breast tissue, including the axillary tail (an extension of breast tissue into the armpit), is located in this quadrant. Therefore, careful examination of this area is crucial for early detection of breast cancer.

A. DVT. B. Venous insufficiency. C. Varicosities. D. Arterial insufficiency.

Correct Answer is D

Explanation

Choice A rationale

Deep vein thrombosis (DVT) involves a blood clot in a deep vein, usually in the legs. Symptoms include swelling, pain, and redness, but not typically cold legs or hair loss, making it unlikely in this scenario.

Choice B rationale

Venous insufficiency occurs when veins struggle to send blood back to the heart, leading to varicose veins, swelling, and skin changes. While it can cause leg discomfort, it does not typically result in cold legs or hair loss.

Choice C rationale

Varicosities are enlarged, twisted veins caused by increased pressure. They can cause pain and swelling but not cold legs or hair loss, making them an unlikely cause of the described symptoms.

Choice D rationale

Arterial insufficiency, caused by poor blood flow due to narrowed arteries, results in symptoms such as cold legs, hair loss, pain, and weakened pulses. The description of cold legs and hair loss fits arterial insufficiency, making it the most likely diagnosis.
