1. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

A. 10-15 seconds
B. 30-35 seconds
C. 20-25 seconds
D. 0-5 seconds

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.

2. Which symptoms are associated with cancer of the colon?

A. constipation, ascites, and mucus in the stool
B. diarrhea, heartburn, and eructation
C. blood in the stools, anemia, and 'pencil-shaped' stools
D. anorexia, hematemesis, and increased peristalsis

Correct answer: C

Rationale: The correct symptoms associated with cancer of the colon are blood in the stools, anemia, and 'pencil-shaped' stools. These symptoms are classic indicators of colorectal cancer. Choices A, B, and D do not typically present in colorectal cancer. Constipation, ascites, and mucus in the stool are more commonly associated with other gastrointestinal conditions. Diarrhea, heartburn, and eructation are not typical symptoms of colon cancer. Anorexia, hematemesis, and increased peristalsis are more indicative of other gastrointestinal issues and not specific to colon cancer.

3. Which biomolecule is responsible for the storage and transfer of genetic information?

A. Carbohydrates
B. Proteins
C. Lipids
D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

4. Which type of medication is most likely to induce xerostomia?

A. Antibiotics
B. Diuretics
C. Local anesthetics
D. Anticholinergics

Correct answer: D

Rationale: The correct answer is D, Anticholinergics. Anticholinergic medications commonly cause xerostomia by inhibiting saliva production, leading to dry mouth. Antibiotics (choice A) are not typically associated with xerostomia. Diuretics (choice B) increase urine production but do not directly affect saliva production. Local anesthetics (choice C) are used to numb specific areas during dental procedures and do not induce xerostomia.

5. Select all that apply. A person who is deficient in vitamin A could consume which of the following to increase vitamin A levels?

A. cantaloupe
B. eggs
C. carrots
D. all of the above

Correct answer: D

Rationale: Vitamin A can be found in high amounts in foods like cantaloupe, eggs, carrots, and milk, all of which help to maintain healthy vision, skin, and immune function.
