1. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. Which of the four phases of emergency management is defined as 'sustained action that reduces or eliminates long-term risk to people and property from natural hazards and their effects'?

• A. Recovery
• B. Mitigation
• C. Response
• D. Preparedness

Correct answer: B

Rationale: The correct answer is B, 'Mitigation.' Mitigation is the phase of emergency management that focuses on sustained actions aimed at reducing or eliminating long-term risks to people and property from natural hazards. Recovery (A) involves restoring and rebuilding infrastructure, housing, and services after a disaster. Response (C) deals with immediate actions taken to save lives and prevent further damage during a disaster. Preparedness (D) involves planning, training, and equipping organizations and communities to effectively respond to emergencies.

3. To raise HDL levels, what is Mrs. Smith advised to do?

• A. quit smoking
• B. increase dietary sodium
• C. take iron supplements
• D. avoid dairy products

Correct answer: A

Rationale: The correct answer is A: quit smoking. Smoking lowers HDL levels, so quitting smoking is crucial to raising HDL levels. Increasing dietary sodium (choice B) is not linked to raising HDL levels and can have negative effects on cardiovascular health. Taking iron supplements (choice C) is not directly related to increasing HDL levels. Avoiding dairy products (choice D) is not necessary to raise HDL levels; in fact, some dairy products like low-fat options can be part of a heart-healthy diet.

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. Why is there an ethical dilemma?

• A. Because the law does not clearly state what is right from what is wrong
• B. Because morality is subjective and it differs from each individual
• C. Because the patient's right coincide with the nurse's responsibility
• D. Because the nurse lacks ethical knowledge to determine what action is correct and what action is unethical

Correct answer: C

Rationale: The correct answer is C because an ethical dilemma arises when the patient's rights conflict with the nurse's responsibilities, requiring a careful balance to ensure ethical care delivery. Choices A and B are incorrect because ethical dilemmas are not solely about legal or subjective moral issues. Choice D is incorrect as nurses are generally equipped with ethical knowledge through education and training, and ethical dilemmas are more about conflicting values and responsibilities rather than a lack of knowledge.
