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

The Angle of Louis, also known as the sternal angle, is located at the level of the 2nd intercostal space. It is a significant landmark in clinical examinations because it is used to locate important areas of the chest, such as the aortic and pulmonic areas, for auscultation.

Choice B rationale

The 3rd intercostal space is not the correct location for the Angle of Louis. The sternal angle is found at the level of the 2nd intercostal space, not the 3rd. Therefore, this option is incorrect.

Choice C rationale

The 2nd rib attaches at the level of the Angle of Louis. The sternal angle is an anatomical landmark where the manubrium and the body of the sternum meet, and it corresponds with the attachment of the 2nd rib.

Choice D rationale

The 4th intercostal space is not the correct location for the Angle of Louis. The sternal angle is located at the 2nd intercostal space, not the 4th. Therefore, this option is incorrect. .

A. Electrical representations of the cardiac cycle that are documented by deflections on recording paper. B. The amount of blood ejected from the left ventricle over 1 minute. C. The amount of blood that is ejected with every heartbeat. D. Electrical impulses of the heart displayed on a screen.

Correct Answer is A

Explanation

Choice A rationale

The electrical representations of the cardiac cycle that are documented by deflections on recording paper are known as an electrocardiogram (ECG). ECGs provide a visual record of the heart's electrical activity, captured through electrodes placed on the body. These deflections correspond to the depolarization and repolarization phases of the heart's muscle cells, translating into P, QRS, and T waves on the ECG strip. The primary function is to diagnose arrhythmias, myocardial infarction, and other heart conditions by identifying abnormal patterns in these waves.

Choice B rationale

This choice describes cardiac output, the amount of blood ejected from the left ventricle over one minute, which is unrelated to the visual documentation of electrical activity provided by an ECG.

Choice C rationale

This choice refers to the stroke volume, the amount of blood ejected with each heartbeat, not the electrical representation of cardiac activity shown on an ECG.

Choice D rationale

This choice is partially correct but does not fully describe an ECG, which includes a detailed recording on paper rather than just visual electrical impulses on a screen.
