1. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

• A. Thiamine (B1)
• B. Riboflavin (B2)
• C. Niacin (B3)
• D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.

2. The small intestine is comprised of the cecum, colon, and rectum. The large intestine includes the duodenum, jejunum, and ileum.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: Both statements are false. The small intestine consists of the duodenum, jejunum, and ileum, while the large intestine includes the cecum, colon, and rectum.

3. A healthcare provider is teaching a client who has constipation about a high-fiber diet. Which of the following foods should be included as sources of fiber? (Select one that does not apply.)

• A. Whole wheat bread
• B. Kidney beans
• C. Refined cereals
• D. Blackberries

Correct answer: C

Rationale: Refined cereals are not a good source of fiber as they have been processed and stripped off most of their fiber content. Whole wheat bread, kidney beans, and blackberries are excellent sources of fiber. Whole wheat bread is made from whole grains, which are high in fiber. Kidney beans are rich in fiber and can help alleviate constipation. Blackberries are a good source of fiber and can aid in promoting bowel regularity.

4. A patient is being cared for by a nurse who has stomatitis following radiation treatment. Which of the following is an appropriate intervention for the nurse to take?

• A. Serve foods without sauces or gravies
• B. Offer mouth rinses with normal saline and water
• C. Serve foods while still at a hot temperature
• D. Instruct the client to drink liquids without a straw

Correct answer: B

Rationale: Offering mouth rinses with normal saline and water is an appropriate intervention for a nurse caring for a patient with stomatitis following radiation treatment. This intervention can help soothe and clean the mouth, promoting comfort and oral hygiene. Choice A is incorrect because serving foods without sauces or gravies does not directly address the client's stomatitis. Choice C is incorrect because serving hot foods can exacerbate discomfort in the client's mouth. Choice D is incorrect because using a straw can help in preventing further irritation in the client's mouth.

5. What type of drug is lamivudine, used for the management of HIV infection?

• A. CCR5 antagonist
• B. fusion inhibitor
• C. nucleoside reverse transcriptase inhibitor
• D. protease inhibitor

Correct answer: C

Rationale: Lamivudine belongs to the class of nucleoside reverse transcriptase inhibitors (NRTIs), making choice C the correct answer. NRTIs like lamivudine work by inhibiting the reverse transcriptase enzyme, an essential component for the HIV virus to replicate. Choices A, B, and D are incorrect because lamivudine does not function as a CCR5 antagonist, fusion inhibitor, or protease inhibitor in the management of HIV infection.
