MULTIPLE CHOICE

1. Identify the triad of anatomic sites of abdominal wall weakness with a potential for hernias.

ANS:  C

The weak places or intervals in the abdominal aponeurosis are (1) the inguinal canal, (2) the femoral rings, and (3) the umbilicus.

REF:   Page 396

2. What composes the lining of a herniated abdominal sac?

ANS:  B

A hernia is a sac lined by peritoneum that protrudes through a defect in the layers of the abdominal wall. Hernias can occur in several places in the abdominal wall, with protrusion of a portion of the parietal peritoneum and often a part of the intestine. Generally, the hernia mass is composed of covering tissues, a peritoneal sac, and any contained viscera.

ANS:  A

The boundaries of the Hesselbach triangle are deep epigastric vessels laterally, inguinal ligament inferiorly, and rectus abdominis muscle medially.

4. Select the most common hernia that occurs in both males and females and name the side on which it would most likely occur.

ANS:  B

Although hernias occur most often in males, the most common hernia in both males and females is the indirect inguinal hernia. Hernias occur more commonly on the right side than on the left.

5. Contributing factors to hernia formation include age, gender, previous surgery, obesity, nutritional status, and pulmonary and cardiac disease. The formation of the hernia at a site of weakness is due to any number of conditions that cause:

ANS:  C

Any number of conditions causing increased pressure within the abdomen can contribute to the formation of a hernia. Loss of tissue turgor occurs with aging and from chronic debilitating diseases. Current evidence suggests that adult male inguinal hernias are likely associated with impaired collagen metabolism and weakening of the fibroconnective tissue of the groin. Smoking has also been noted as a contributing factor to hernia formation.
