1. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

2. Which change during pregnancy is related to the slowing of the gastrointestinal tract?

• A. Diarrhea
• B. Constipation
• C. Decreased absorption of iron
• D. Decreased absorption of calcium

Correct answer: B

Rationale: During pregnancy, the gastrointestinal tract tends to slow down, leading to constipation. This is due to hormonal changes that relax the intestinal muscles, allowing more time for nutrient absorption and ultimately leading to constipation. Diarrhea is not typically associated with the slowing of the gastrointestinal tract during pregnancy. Decreased absorption of iron and calcium may occur during pregnancy due to increased demands, but they are not directly related to the slowing of the gastrointestinal tract.

3. Larry, 55 years old, who is suspected of having colorectal cancer, is admitted to the CI. After taking the history and vital signs the physician does which test as a screening test for colorectal cancer.

• A. Barium enema
• B. Carcinoembryonic antigen
• C. Annual digital rectal examination
• D. Proctosigmoidoscopy

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. Which physiologic role does vitamin C play in the body?

• A. Transcribing DNA to RNA
• B. Absorption and regulation of calcium
• C. Protects integrity of cellular membranes
• D. Catalyst for synthesis of blood-clotting factors

Correct answer: C

Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.

5. You would expect that after an abdominal perineal resection, the type of colostomy that will be use is?

• A. Double barrel colostomy
• B. Temporary colostomy
• C. Permanent colostomy
• D. An Ileostomy

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
