Explanation

Each category must have at least 1 response option selected

Finding	Normal	Abnormal
Tympany to percussion over the intestines	✅
Loose, watery stool		✅
Suprapubic tenderness		✅
A non-palpable spleen	✅
Aortic pulsation in the epigastric area	✅
Decreased bowel sounds		✅

Rationale:

Tympany to percussion over the intestines (Normal):

Tympany is expected due to the presence of gas in the intestines.

Loose, watery stool (Abnormal):

This is indicative of diarrhea, which may point to gastrointestinal upset or infection.

Suprapubic tenderness (Abnormal):

Tenderness in this area may indicate bladder infection, inflammation, or pelvic issues.

A non-palpable spleen (Normal):

The spleen is generally not palpable in healthy individuals unless it is enlarged (splenomegaly).

Aortic pulsation in the epigastric area (Normal):

Mild pulsations may be felt in thin or normal-weight individuals. However, a widened or strong pulsation could suggest an abdominal aortic aneurysm.

Decreased bowel sounds (Abnormal):

Hypoactive or absent bowel sounds may indicate decreased intestinal motility, such as in ileus or peritonitis.

A. The patient can read at 20 feet what a person with normal vision can read at 30 feet. B. The patient can read from 30 feet what a person with normal vision can read from 20 feet. C. At 30 feet the patient can read the entire chart. D. The patient can read the chart from 20 feet in the left eye and 30-feet in the right eye.

Correct Answer is A

Explanation

A. A vision of 20/30 means that the patient can read at 20 feet what a person with normal vision can read at 30 feet, indicating mild visual impairment.

B. This reverses the explanation of 20/30 vision and is incorrect.

C. This option incorrectly describes the Snellen chart results, which measure clarity of vision at specific distances, not entire chart reading ability.

D. This option confuses visual acuity for each eye; Snellen scores do not indicate different distances for each eye.
