1. Where is Vitamin E commonly found?

A. produced by bacteria in the GI tract
B. synthesized by the body through sunlight exposure
C. associated with beriberi deficiency
D. present in vegetable oils

Correct answer: D

Rationale: Vitamin E is an antioxidant commonly found in sources like vegetable oils, nuts, seeds, and green leafy vegetables. It plays a crucial role in protecting cells from damage. Choices A and B are incorrect as Vitamin E is not produced by bacteria in the GI tract nor synthesized by sunlight exposure. Choice C is incorrect as beriberi is a deficiency of Vitamin B1 (thiamine), not Vitamin E.

2. Which of the following terms describes the amount of blood ejected per heartbeat?

A. Stroke volume
B. Cardiac output
C. Ejection fraction
D. Afterload

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

3. A client with cholecystitis is being taught about required dietary modifications. Which of the following foods is appropriate for the client's diet?

A. Creamed chicken
B. Roast turkey
C. Ice cream
D. Macaroni and cheese

Correct answer: B

Rationale: Roast turkey is the most appropriate choice for a client with cholecystitis. Foods that are high in fat content, like creamed chicken, ice cream, and macaroni and cheese, should be avoided in cholecystitis as they can exacerbate symptoms due to the reduced ability of the gallbladder to process fats. Roast turkey is a leaner option that is better tolerated by individuals with cholecystitis.

4. While a team effort is necessary in the operating room (OR) for efficient and quality patient care delivery, the number of people in the room should be limited for infection control purposes. Which roles comprise this team?

A. Surgeon, anesthesiologist, scrub nurse, radiologist, orderly
B. Surgeon, assistants, scrub nurse, circulating nurse, anesthesiologist
C. Surgeon, assistant surgeon, anesthesiologist, scrub nurse, pathologist
D. Surgeon, assistant surgeon, anesthesiologist, intern, scrub nurse

Correct answer: B

Rationale: The roles typically present in an operating room team include the surgeon, assistants (which may include an assistant surgeon), scrub nurse, circulating nurse, and anesthesiologist. These roles are directly involved in the operation and patient care. Choice B is correct. Choice A includes a radiologist and an orderly, who are not typically part of the immediate surgical team in the OR. Choice C includes a pathologist, who usually works in a laboratory outside of the OR. Choice D includes an intern, who may or may not be part of the team, depending on the specific circumstances and hospital policy. These explanations make choices A, C, and D incorrect.

5. Which statement about essential nutrients should the nurse include?

A. Fat-containing foods can help to decrease triglyceride levels.
B. Animal sources of protein contain 20 essential amino acids.
C. Carbohydrates are the primary source of fuel for muscles and the brain.
D. High-fiber foods are a good source of energy.

Correct answer: C

Rationale: The correct answer is C because carbohydrates are indeed the primary source of fuel for muscles and the brain. Choice A is incorrect because while certain fats are essential, they do not help decrease triglyceride levels. Choice B is incorrect because animal sources of protein do not contain all 20 essential amino acids. Choice D is incorrect because although high-fiber foods are important for digestion and overall health, they are not a direct source of energy.
