Question 1

Which of the following dairy products is MOST LIKELY to contain the least lactose for those who are lactose intolerant?

Accepted Answer

Greek-style whole-fat yogurt

Answer

Explanation:
Because Greek-style yogurt is thicker than regular whole-fat yogurt, more of the whey is removed, and the lactose is part of the whey, so those who are lactose intolerant are more likely to tolerate Greek yogurt than other dairy products. Those who are lactose intolerant lack the enzyme needed to digest lactose, resulting in stomach cramps, gas and distention, and diarrhea after eating or drinking dairy products. Some dairy products are now lactose-free, and Lactaid can be taken to replace the missing enzymes.

Question 2

Following an esophagoscopy to obtain a biopsy of the thoracic esophagus, which of the following symptoms MOST indicates the need for emergent care for perforation?

Accepted Answer

Chest pain, dysphagia, and tachycardia

Answer

Explanation:
Following an esophagoscopy to obtain a biopsy of the thoracic esophagus, chest pain, dysphagia, and tachycardia are indications of the need for emergent care for perforation. The onset of fever is often rapid, and Hamann's sign (crunching, rasping precordial sound coinciding with the heartbeat) is positive because of leakage of air to the mediastinum. Perforation is usually confirmed radiologically although CT or endoscopy may be necessary if the perforation cannot be seen on x-ray.

Question 3

If a patient scheduled for a colonoscopy has a nose stud and enclosed lip ring, which of the following actions is appropriate?

Accepted Answer

Remove both prior to the procedure

Answer

Explanation:
If a patient scheduled for a colonoscopy has a nose stud and enclosed lip ring, they should both be removed prior to the procedure because they pose the risk of trauma and aspiration if they become dislodged. Nose studs are removed by applying gentle pressure and pulling straight out. Enclosed lip rings are removed by applying pressure inside of the ring to force the ends apart. Barbell-type jewelry has a bead on the end that is unscrewed in a counter-clockwise direction.

Question 4

Cancer of the colon and rectum is primarily which of the following types of cancer?

Accepted Answer

Adenocarcinoma

Answer

Explanation:
Cancer of the colon and rectum is primarily (about 95%) adenocarcinoma, which arises in the epithelial lining of the bowel. Adenocarcinomas often develop from a precancerous polyp. Early detection through screening is essential because colorectal cancers may remain essentially asymptomatic until they are advanced and changes in bowel habits or rectal bleeding occur. Hemorrhage may occur if the tumor invades blood vessels, and obstruction may occur as the mass enlarges.

Question 5

How soon after collection should duodenal aspirate be transported to the laboratory?

Accepted Answer

Immediately

Answer

Explanation:
Duodenal aspirate should be immediately transported to the laboratory because it must be examined within 60 minutes of collection. The aspirate should be collected (at least 2 mL) in a sterile centrifuge tube. Duodenal aspirates may be useful in diagnosing Giardia duodenalis and Strongyloides stercoralis.
